PART I

ITEM 1.   BUSINESS

GENERAL

Overview and Description of Material Subsidiaries

AEP was incorporated under the laws of the State of New York in 1906 and reorganized in 1925. It is a public utility holding company that owns, directly or indirectly, all of the outstanding common stock of its public utility subsidiaries and varying percentages of other subsidiaries.

The service areas of AEP’s public utility subsidiaries cover portions of the states of Arkansas, Indiana, Kentucky, Louisiana, Michigan, Ohio, Oklahoma, Tennessee, Texas, Virginia and West Virginia. The transmission facilities of AEP’s public utility subsidiaries are interconnected and their operations are coordinated. Transmission networks are interconnected with extensive distribution facilities in the territories served. The public utility subsidiaries of AEP have traditionally provided electric service, consisting of generation, transmission and distribution, on an integrated basis to their retail customers. Restructuring laws in Michigan, Ohio and the ERCOT area of Texas have caused AEP public utility subsidiaries in those states to unbundle previously integrated regulated rates for their retail customers.  In Ohio, AEP’s regulated utility operates its distribution and transmission assets while its former generation assets are owned and operated by a competitive generation affiliate.affiliates.

The member companies of the AEP System have contractual, financial and other business relationships with the other member companies, such as participation in the AEP System savings and retirement plans and tax returns, sales of electricity and transportation and handling of fuel. The companies of the AEP System also obtain certain accounting, administrative, information systems, engineering, financial, legal, maintenance and other services at cost from a common provider, AEPSC.

FINANCING

General

Companies within the AEP System generally use short-term debt to finance working capital needs.  Short-term debt may also be used to finance acquisitions, construction and redemption or repurchase of outstanding securities until such needs can be financed with long-term debt.  In recent history, short-term funding needs have been provided for by cash on hand borrowing under AEP's revolving credit agreements and AEP’s commercial paper program.  Funds are made available to subsidiaries under the AEP corporate borrowing program.  Certain public utility subsidiaries of AEP also sell accounts receivable to provide liquidity.  See Management’s Discussion and Analysis of Financial Condition and Results of Operations, included in the 20142016 Annual Reports, under the heading entitled Financial Condition for additional information concerning short-term funding and our access to bank lines of credit, commercial paper and capital markets.

AEP’s revolving credit agreements (which backstop the commercial paper program) include covenants and events of default typical for this type of facility, including a maximum debt/capital test.  In addition, the acceleration of AEP’s payment obligations, or the obligations of certain of ourits major subsidiaries, prior to maturity under any other agreement or instrument relating to debt outstanding in excess of $50 million, would cause an event of default under these credit agreements. As of December 31, 2014,2016, AEP was in compliance with its debt covenants.  With the exception of a voluntary bankruptcy or insolvency, any event of default has either or both a cure period or notice requirement before


termination of the agreements.  A voluntary bankruptcy or insolvency of AEP or one of its significant subsidiaries would be considered an immediate termination event.  See Management’s Discussion and Analysis of Financial Condition and Results of Operations, included in the 20142016 Annual Reports, under the heading entitled Financial Condition for additional information with respect to AEP’s credit agreements.

AEP’s subsidiaries have also utilized, and expect to continue to utilize, additional financing arrangements, such as securitization financings and leasing arrangements, including the leasing of coal transportation equipment and facilities.

ENVIRONMENTAL AND OTHER MATTERS

General

AEP’sAEP subsidiaries are currently subject to regulation by federal, state and local authorities with regard to air and water-quality control and other environmental matters, and are subject to zoning and other regulation by local authorities.  The environmental issues that we believemanagement believes are potentially material to the AEP systemSystem are outlined below.

Clean Water Act Requirements

Our operationsOperations for AEP subsidiaries are subject to the Federal Clean Water Act, which prohibits the discharge of pollutants into waters of the United States except pursuant to appropriate permits, and regulates systems that withdraw surface water for use in our power plants.  In 2014, the Federal EPA issued a final rule setting forth standards for existing power plants that is intended to reduce mortality of aquatic organisms pinned against a plant’s cooling water intake screen (impingement) or entrained in the cooling water.  The standards affect all plants withdrawing more than two million gallons of cooling water per day and establish specific intake design and intake velocity standards meant to allow fish to avoid or escape impingement.  Compliance with this standard is required within eight years of the effective date of the final rule.  The standard for entrainment for existing facilities requires a site-specific evaluation of the available measures for reducing entrainment.  Challenges to this final rule have been consolidated in the U.S. Court of Appeals for the Second Circuit, and additional changes could be made to this rule as a result of review by the court.

TheIn November 2015, the Federal EPA is also engaged in rulemakingissued a final rule to update the technology-based standards that govern discharges from new and existing power plants under the Clean Water Act’s National Pollutant Discharge Elimination System program.  These standards were last updated over 20 years ago, and the Federal EPA proposed revised standards in 2013.  A final rule is expected in September 2015. For additional information, see Management’s Discussion and Analysis of Financial Condition and Results of Operations under the headings entitled Environmental Issues.

Coal Ash Regulation

OurAEP’s operations produce a number of different coal combustion products, including fly ash, bottom ash, gypsum and other materials.  In December 2008, the breach of a dike at the Tennessee Valley Authority’s Kingston Station resulted in a spill of several million cubic yards of ash into a nearby river and onto private properties, prompting federal and state reviews of ash storage and disposal practices at many coal-fired electric generating facilities, including ours.  AEP operates 37 ash ponds, and we manage these ponds in a manner that complies with state and local requirements, including dam safety rules designed to assure the structural integrity of these facilities.  We also operate a number of dry disposal facilities in accordance with state standards, including ground water monitoring and other applicable standards.  In December 2014,Effective October 2015, the Federal EPA signedadopted a rule to regulate the disposal and beneficial re-use of coal combustion residuals, including fly ash and bottom ash generated at coal-fired electric generating units.  The final rule requires certain standards for location, groundwater monitoring and dam stability to be met at landfills and certain surface impoundments at operating facilities on a schedule spanning approximately four years after publication of the final rule in the Federal Register. If existing disposal facilities cannot meet these standards, they will be required to close, but the time frame for closure may be extended if adequate alternative disposal options are not available. Extensions are available for completion of certain activities. For additional information regarding the Federal EPA action taken to regulate the disposal and beneficial re-use of coal combustion residuals and the potential impact on our operations, see Management’s Discussion and Analysis of Financial Condition and Results of Operations under the headings entitled Environmental Issues-Coal Combustion Residual Rule.

Clean Air Act Requirements

The CAA establishes a comprehensive program to protect and improve the nation’s air quality and control mobile and stationary sources of air emissions.  The major CAA programs affecting ourAEP’s power plants are described below.  The states implement and administer many of these programs and could impose additional or more stringent requirements.


AEP has made significant long-term investments in environmental controls to reduce air emissions from its power plants. Between 2000 and 2016, AEP invested approximately $8.5 billion in environmental controls, primarily related to CAA, that have significantly reduced emissions. From 2001 and including projections through 2017, AEP expects its emissions of mercury will be lower by approximately 8,300 pounds, a reduction of approximately 87%. Since 1990 and including projections through 2017, AEP expects its emissions of SO2 and NOx will be lower by approximately 1,460,000 tons and 560,000 tons, respectively, a reduction of approximately 94% and 89%, respectively.

The Acid Rain Program

The 1990 Amendments to the CAA include a cap-and-trade emission reduction program for SO2 emissions from power plants.  By 2000, the program established a nationwide cap on power plant SO2 emissions of 8.9 million tons per year and required further reductions in 2010.  The 1990 Amendments also contain requirements for power plants to reduce NOx emissions through the use of available combustion controls.

The success of the SO2 cap-and-trade program encouraged the Federal EPA and the states to use it as a model for other emission reduction programs.  We continueAEP continues to meet ourits obligations under the Acid Rain Program through the installation of controls, use of alternate fuels and participation in the emissions allowance markets.  Subsequent programs developed by the Federal EPA have imposed more stringent SO2 and NOx emission reduction requirements than the Acid Rain Program on many of ourAEP facilities.  We have installed additionalAdditional controls and taken other actions have been taken to achieve compliance with these programs.programs at these facilities.

National Ambient Air Quality Standards

The CAA requires the Federal EPA to review the available scientific data for criteria pollutants periodically and establish a concentration level in the ambient air for those substances that is adequate to protect the public health and welfare with an extra safety margin.  The Federal EPA also can list additional pollutants and develop concentration levels for them.  These concentration levels are known as national ambient air quality standards (NAAQS).

Each state identifies the areas within its boundaries that meet the NAAQS (attainment areas) and those that do not (nonattainment areas).  Each state must develop a state implementation plan (SIP) to bring nonattainment areas into compliance with the NAAQS and maintain good air quality in attainment areas.  All SIPs are submitted to the Federal EPA for approval.  If a state fails to develop adequate plans, the Federal EPA develops and implements a plan.  As the Federal EPA reviews the NAAQS and establishes new concentration levels, the attainment status of areas can change and states may be required to develop new SIPs.  In 2008, the Federal EPA issued revised NAAQS for both ozone and fine particulate matter (PM2.5).  The PM2.5 standard was remanded by the D.C. Circuit Court of Appeals, and a new

rule was signed by the administrator in December 2012 that lowerslowered the annual standard.  A new ozone standard was proposedadopted in 2014.2015.  The Federal EPA also adopted a new short-term standard for SO2 in 2010, a lower standard for NOx in 2010, and confirmed the existing standard for lead in 2014.2016.  The existing standard for carbon monoxide was retained in 2011.  The states are in the process of developing new SIPs for the SO2, NOx and PM2.5 and ozone standards, which could result in more stringent emission limitations being imposed on our facilities. Additional designations of SO2 nonattainment areas and finalization of a more stringent ozone standard could also lead to the imposition of more stringent emission limitations on ourAEP facilities.

In 2005, the Federal EPA issued the Clean Air Interstate Rule (CAIR), which requiresrequired additional reductions in SO2 and NOx emissions from power plants and assists states developing new SIPs to meet the NAAQS.   In August 2011, the Federal EPA issued a final rule to replace CAIR (the Cross State Air Pollution Rule (CSAPR)) that contains more stringent requirements to control SO2 and NOx emissions from fossil fuel-fired electric generating units in 27 states and the District of Columbia.  Petitions for review were filed with the U.S. Court of Appeals for the District of Columbia Circuit, and CSAPR was vacated.  That decision was subsequently reversed by the U.S. Supreme Court and remanded back to the U.S. Court of Appeals for further proceedings. The Federal EPA filed a motion to lift the stay and allow Phase I of CSAPR to take effect on January 1, 2015 and Phase II to take effect on January 1, 2017. The court granted the Federal EPA'sEPA’s motion, an interim final rule has been issued, and the court has remanded certain state budgets to Federal EPA for further consideration ofrulemaking while the petitions for review on CSAPR will continue during 2015 while Phase I isrule remains in effect. Federal EPA has proposed more stringent NOx budgets for 23 states during the 2017 ozone season. For additional information regarding CAIR and CSAPR, see Management’s Discussion and Analysis of Financial Condition and Results of Operations under the headings entitled Environmental Issues-Clean Air Act Requirements.


Hazardous Air Pollutants

As a result of the 1990 Amendments to the CAA, the Federal EPA investigated hazardous air pollutant (HAP) emissions from the electric utility sector and submitted a report to Congress, identifying mercury emissions from coal-fired power plants as warranting further study.  In 2011, the Federal EPA issued a final rule setting Maximum Achievable Control Technology (MACT) standards for new and existing coal and oil-fired utility units and New Source Performance Standards (NSPS) for emissions from new and modified power plants.  Petitions for review of the MACT standards were denied by the U.S. Court of Appeals for the D.C. Circuit, but in 2014 the U.S. Supreme Court granted certiorari to determine whetherdetermined that Federal EPA should have consideredacted unreasonably in refusing to consider costs in determining if it was appropriate and necessary to regulate hazardous air pollutant emissions from electric generating units. Federal EPA has issued a supplemental finding and the rule remains in effect. For additional information regarding MACT, see Management’s Discussion and Analysis of Financial Condition and Results of Operations under the headings entitled Environmental Issues-Clean Air Act Requirements.

Regional Haze

The CAA establishes visibility goals for certain federally designated areas, including national parks, and requires states to submit SIPs that will demonstrate reasonable progress toward preventing impairment of visibility in these areas (Regional Haze program).  In 2005, the Federal EPA issued its Clean Air Visibility Rule (CAVR), detailing how the CAA’s best available retrofit technology requirements will be applied to facilities built between 1962 and 1977 that emit more than 250 tons per year of certain pollutants in specific industrial categories, including power plants.

PSO executed a settlement with the Federal EPA and the State of Oklahoma to comply with Regional Haze program requirements in Oklahoma, and the settlement is now codified in the Oklahoma SIP. PSO is in the process of implementing a settlement with the requirements of the SIP. Federal EPA in order to comply withhas disapproved portions of the Regional Haze program requirements in Oklahoma. Federal EPA is likely to issueArkansas and Texas SIPs, and finalized a Federal Implementation Plan for Arkansas in 2015.2016.  For additional information regarding CAVR and the Regional Haze program requirements, see Management’s Discussion and Analysis of Financial Condition and Results of Operations under the headings entitled Environmental Issues-Clean Air Act Requirements.

Climate Change

We continueAEP has taken action to support a federal legislative approach to energy policy as the most effective means of reducing emissions of CO2reduce and other greenhouse gases (generally referred to as CO2) that recognizes that a reliable and affordable electricity supply is vital to economic recovery and growth.  We do not believe regulatingoffset CO2 emissions under the CAA is the appropriate solution.  In the past decade, we have taken voluntary actions to reducefrom its generating fleet and offset ourexpects CO2 emissions from its operations to continue to decline due to the retirement of some of its coal-fired generation units, and have complied with state energy policies designedactions taken to reduce carbon emissions through increasing reliance on renewable resourcesdiversify the generation fleet and expanding ourincrease energy efficiency programs.  

AEP'swhere there is regulatory support for such activities. AEP’s total projected CO2 emissions in 20142017 (not including our ownership inemissions from the Kyger Creek and Clifty Creek plants) werePlants) are approximately 12090 million metric tons.  This representstons, a 46% reduction of 18% compared to our 2005 CO2 emission of approximately 146 million metric tons. We expect minor variations infrom AEP’s 2000 CO2 emissions of approximately 167 million metric tons. Federal EPA has taken action to regulate CO2 emissions from new and existing fossil fueled electric generating units under the existing provisions of the CAA.  The Federal EPA published the Clean Power Plan in October 2015. Such actions, including the near-term as potential salesClean Power Plan, are being legally challenged by numerous parties and emission increases from rebounding economic activityfinal regulatory outcomes remain uncertain.  In February 2016, the U.S. Supreme Court issued a stay on the final Clean Power Plan, including all of the deadlines for submission of initial or final state plans. The stay will remain in effect until a final decision is issued by the U.S. Court of Appeals for the District of Columbia Circuit and the U.S. Supreme Court considers any petition for review.For additional information regarding the Federal EPA action taken to be offset by expected changes in generation sources.regulate CO2 emissions, including the Clean Power Plan, see Management’s Discussion and Analysis of Financial Condition and Results of Operations under the headings entitled Environmental Issues-Climate Change, CO2 Regulation and Energy Policy.

We expect ourManagement expects emissions to continue to decline over time as we diversify ourAEP diversifies generating sources and operateoperates fewer coal units.  The projected decline in coal-fired generation is due to a number of factors, including the ongoing cost of operating older units, the relative cost of coal and natural gas as fuel sources, increasing environmental regulations requiring significant capital investments and changing commodity market fundamentals.  OurManagement’s strategy for this transformation includes diversifying ourAEP’s fuel portfolio and generating more electricity from natural gas, increasing energy efficiency and investing in renewable resources, where there is regulatory support.



In the absence of comprehensive climate change legislation, the Federal EPA has taken action to regulate CO2 emissions under the existing provisions of the CAA.  Such actions are being legally challenged by numerous parties and final regulatory outcomes remain uncertain.  For additional information regarding the Federal EPA action taken to regulate CO2 emissions, see Management’s Discussion and Analysis of Financial Condition and Results of Operations under the headings entitled Environmental Issues Climate Change, CO2 Regulation and Energy Policy.

OurAEP’s fossil fuel-fired generating units are large sources of CO2 emissions.  If substantial additional CO2 emission reductions are required, there will be significant increases in capital expenditures and operating costs which would hasten the ultimate retirement of older, less-efficient, coal-fired units.  To the extent we install additional controls on our generation plantsinvestments are made to limitreduce CO2 emissions and receive regulatory approvals to increase our rates, return on capital investment would have a positive effect on future earnings.  Prudently incurred capital investments made by ourAEP subsidiaries in rate-regulated jurisdictions to comply with legal requirements and benefit customers are generally included in rate base for recovery and earn a return on investment.  WeManagement would expect these principles to apply to investments made to address new environmental requirements.  However, requests for rate increases reflecting these costs can affect us adverselyhave adverse effects because our regulators could limit the amount or timing of increased costs that weAEP would recover through higher rates. For our sales of energy into thecompetitive markets, however, there is no such recovery mechanism.

Renewable Sources of Energy

Some of theThe states we serveAEP serves, other than Kentucky, West Virginia and Tennessee, have established mandatory or voluntary programs to increase the use of energy efficiency, alternative energy, or renewable energy sources (Arkansas, Indiana, Louisiana, Michigan, Ohio, Oklahoma, Texas, Virginia and West Virginia).  During 2014 in support of our goals or requirements, our operating companies procured rights to an additional 199 MW of wind power and atsources.

At the end of 2014 our2016, the AEP operating companies had long-term contracts for 2,183 MW2,630 MWs of wind and 10 MWMWs of solar power.power delivering renewable energy to the companies’ customers. In addition, the Indiana Utility Regulatory Commission has approved I&M's proposal for a self-build&M completed construction of four solar projects that make up I&M’s 14.7 MW Clean Energy Solar Pilot Project (15.7 MW).  When(CESPP) that was approved by the additional projects under construction and/or pending regulatory approval are addedIndiana Utility Regulatory Commission. This resulted in a total of 2,655 MWs of wind and netted against one wind contract that is expiring at the end of 2015, the total renewable portfolio will be 2,715 MW to serve oursolar in-service serving AEP’s regulated operating company customers.  Weutilities. Management actively manage ourmanages AEP’s compliance position and areis on pace to meet the relevant requirements or benchmarks in each applicable jurisdiction.


11The growth of AEP’s renewable portfolio reflects the company’s strategy to diversify its generation resources to provide clean energy options to customers that meet both energy and capacity needs. In addition to gradually reducing AEP’s reliance on coal-fueled generating units, the growth of renewables and natural gas helps AEP to maintain a diversity of generation resources.


The integrated resource plans filed with state regulatory commissions by AEP’s regulated utility subsidiaries reflect AEP’s renewable strategy to balance reliability and cost with customers’ desire for clean energy in a carbon-constrained world. The Company has committed significant capital investments to modernize the electric grid and integrate these new resources. Transmission assets of the AEP System interconnect approximately 9,000 MWs of renewable energy resources of third parties, and AEP’s transmission development initiatives are designed to facilitate the interconnection of additional renewable energy resources.

AEP Energy Supply LLC owns 311 MWs of wind capacity in Texas and sells its energy entitlement to third parties or liquidates at market. In 2016, AEP took several major steps in executing its strategic plan to develop and market a merchant distributed resource portfolio. AEP Renewables, LLC, was formed in April 2016 to develop and/or acquire large scale renewable projects backed with long-term contracts with credit worthy counterparties. In 2016, AEP Renewables, LLC brought into service a 26 MW solar project in Utah. The company also owns a 62 MW solar project in Nevada that was brought into service in 2017.

AEP OnSite Partners, LLC works directly with wholesale and large retail customers to provide tailored solutions to reduce their energy costs based upon market knowledge, innovative applications of technology and deal structuring capabilities. The company targets opportunities in distributed solar, combined heat and power, energy storage, waste heat recovery, energy efficiency, peaking generation and other energy solutions that create value for customers. AEP OnSite Partners, LLC pursues and develops behind the meter projects with credit-worthy customers. As of December 31, 2016, AEP OnSite Partners, LLC owned projects operating in six states, including 15 MWs of installed solar capacity and another 21 MWs of solar projects under construction in five states.



End Use Energy Efficiency

Beginning in 2008, AEP ramped up efforts to reduce energy consumption and peak demand through the introduction of additional energy efficiency and demand response programs.  These programs, commonly and collectively referred to as demand side management, were implemented in jurisdictions where appropriate cost recovery was available.  Since that time, AEP operating companies have implemented over 100125 programs across the AEP service territory and in most of the states we serve.AEP serves.  For the period 2008 through 2014,2016, these programs have reduced annual consumption by over 5.26.0 million megawatt hours and peak demand by over 1,500 MW.  Toapproximately 2,000 MWs.  AEP estimates that its operating companies spent approximately $1 billion during that period to achieve these levels, AEP operating companies invested approximately $700 million during the same period.   These results are preliminary and subject to independent third party evaluation and verification of savings, as required.levels.  

Energy efficiency and demand reduction programs have received regulatory support in most of the states we serve,AEP serves, and appropriate cost recovery will be essential for usAEP operating companies to continue and expand these consumer offerings. Appropriate recovery of program costs, lost revenues, and an opportunity to earn a reasonable return ensures that energy efficiency programs are considered equally with supply side investments.  Going forward, we will work closely with regulatorsAs AEP continues to ensure that plans are in placetransition to meet specific regulatory and legislativea cleaner, more efficient energy future, energy efficiency and/orand demand reduction targets presentresponse programs will continue to play an important role in how the respective jurisdictions.company serves its customers.

AEP believes its experience providing robust energy efficiency programs in several states positions the company to be a cost-effective provider of these programs as states develop their implementation plans.

Corporate Governance

In response to environmental issues and in connection with its assessment of ourAEP’s strategic plan, ourthe Board of Directors continually reviews the risks posed by our actions.new environmental rules and requirements that could accelerate the retirement of coal-fired generation assets. The Board of Directors is informed of any new material issues, including changes to environmental regulations and proposed regulation or legislation that couldwould affect the Company.company.  The Board’s Committee on Directors and Corporate Governance oversees the Company’scompany’s annual Corporate Accountability Report, which includes information about the Company’scompany’s environmental, financial and social performance.

Other Environmental Issues and Matters

The Comprehensive Environmental Response, Compensation and Liability Act of 1980 imposes costs for environmental remediation upon owners and previous owners of sites, as well as transporters and generators of hazardous material disposed of at such sites.  See Note 6 to the consolidated financial statements entitled Commitments, Guarantees and Contingencies, included in the 20142016 Annual Reports, under the heading entitled The Comprehensive Environmental Response Compensation and Liability Act (Superfund) and State Remediation for further information.

Environmental Investments

Investments related to improving AEP System plants’ environmental performance and compliance with air and water quality standards during 2012, 20132014, 2015 and 20142016 and the current estimatesestimate for 2015, 2016 and 2017 are shown below, in each case including debt AFUDC.below. These investments include both environmental as well as other related spending. Estimated construction expenditures are subject to periodic review and modification and may vary based on the ongoing effects of regulatory constraints, environmental regulations, business opportunities, market volatility, economic trends and the ability to access capital.  AEP expects to make substantial investments in future years in addition to the amounts set forth below in connection with the modification and addition of facilities at generation plants for environmental quality controls.  Such future investments are needed in order to comply with air and water quality standards that have been adopted and have deadlines for compliance after 20142016 or have been proposed and may be adopted.  Future investments could be significantly greater if emissions reduction requirements are accelerated or otherwise become more onerous or if CO2 becomes regulated at existing facilities.onerous. The cost of complying with applicable environmental laws, regulations and rules is expected to be material to the AEP System. WeAEP typically recoverrecovers costs of complying with environmental standards from customers through rates in regulated jurisdictions.  For our sales of energy into the markets,AEP’s merchant generation units however, there is no such recovery mechanism.  Failure to recover these costs could reduce our future net income and cash flows and possibly harm ourAEP’s financial condition.  See Management’s Discussion and Analysis of Financial Condition and Results of Operations under the heading entitled Environmental Issues and Note 6 to the consolidated financial statements, entitled Commitments, Guarantees and Contingencies, included in the 20142016 Annual Reports, for more information regarding environmental expenditures in general.

Counterparty Risk Management

Counterparties and exchanges may require cash or cash related instruments to be deposited on transactions as margin against open positions.  As of December 31, 2014, counterparties posted approximately $9 million in cash, cash equivalents or letters of credit with AEPSC for the benefit of AEP’s public utility subsidiaries (while, as of that date, AEP’s public utility subsidiaries posted approximately$53 million with counterparties and exchanges).  Since open trading contracts are valued based on market prices of various commodities, exposures change daily.  See Management’s Discussion and Analysis of Financial Condition and Results of Operations, included in the 2014 Annual Reports, under the heading entitled Quantitative and Qualitative Disclosures About Market Risk for additional information.

Fuel Supply

The 2012 and 2013 results include fuel used and transported by OPCo, a utility subsidiary that is not part of the Vertically Integrated Utilities segment.  OPCo’s results appear here because it retained its generation until year-end 2013 at which point all of its generation was transferred to AGR which transferred portions to APCo and KPCo.

Thefollowing table shows the owned and leased generation sources of fuelby type (including wind purchase agreements), on an actual net generation (MWhs) basis, used by the Vertically Integrated Utilities:
2014 2013 20122016 2015 2014
Coal and Lignite72% 75% 71%61% 66% 69%

Natural Gas11% 13% 17%13% 11% 10%
Hydroelectric and other1% <1% <1%
Renewables10% 7% 6%

A price increase/decrease in one or more fuel sources relative to other fuels, as well as the addition of renewable resources, may result in the decreased/increased use of other fuels.  AEP’s overall 20142016 fossil fuel costs for the Vertically Integrated Utilities were relatively unchangedremained flat on a dollar per MMBtu basis from 2013. A slight decline in the cost of coal was offset by an increase in natural gas prices, during the first half of 2014.2015.

Coal and Lignite

AEP’s Vertically Integrated Utilities procure coal and lignite under a combination of purchasing arrangements including long-term contracts, affiliate operations and spot agreements with various producers and coal trading firms.  Coal consumption in 2014 was higher than 20132016 decreased from 2015 due to strongthe decreased demand for coal-fired generation resulting from low natural gas prices, and the retirement of Northeastern 4 and Welsh 2 in the East during the first half of the year, but coal2016. Coal inventories ended the year at targetabove-target levels on a system basis.

Management believes that the Vertically Integrated Utilities will be able to secure and transport coal and lignite of adequate quality and in adequate quantities to operate their coal and lignite-fired units.  Through subsidiaries, AEP owns, leases or controls more than 4,9903,722 railcars, approximately 509468 barges, 12 towboats and a coal handling terminal with approximately 18 million tons of annual capacity to move and store coal for use in ourAEP generating facilities.  See AEP River Operations for a discussion of AEP’s for-profit liquid, coal and other dry-bulk commodity transportation operations that are not part of this segment.

Spot market prices for coal decreased throughout 2014.  The decreased spot coal prices during the year can be attributedstarted to weak European coal demand, and relatively inexpensive natural gas,strengthen in the second half of 2014.  Approximately2016. The increased spot coal prices reflect tighter supplies and increased demand for export coal. As of December 31, 2016, slightly less than half of the coal purchased by AEP isAEP’s subsidiaries was procured through term contracts.  As those contracts expire they areor re-open for price adjustments, needed tonnage is replaced with contracts at current market prices.prices as necessary.  The price impact of this process is reflected in subsequent periods.  The price paid for coal delivered in 2014 decreased2016 remained relatively flat from the prior year primarily due to a decrease in spot coal prices and heavier reliance on shorter term contracts.year.

The coal supplies at the Vertically Integrated Utilities plants vary from time to time depending on various factors, including, but not limited to, demand for electric power, unit outages, transportation infrastructure limitations, space limitations, plant coal consumption rates, availability of acceptable coals, labor issues and weather conditions, which may interrupt production or deliveries. As of December 31, 2014,2016, the Vertically Integrated Utilities coal inventory was approximately 3142 days of full load burn. While inventory targets vary by plant and are changed as necessary, the current coal inventory target for the Vertically Integrated Utilities is approximately 30 days.

Natural Gas

The Vertically Integrated Utilities consumed over 96approximately 104 billion cubic feet of natural gas during 20142016 for generating power. This represents a decreasean increase of 15%16% from 2013; 96.1 billion cubic feet2015.  Total gas consumption for the Vertically Integrated Utilities was higher year over year due to lower natural gas prices in 2014 as compared to 112.4 billion cubic feet in 2013, excluding OPCo usage.  While AEP’s natural gas-fired generating capacity has increased over the past several years withfirst half of 2016 and the addition of Clinch River, Units 1 and 2 and Big Sandy, Unit 1 as gas retrofitted units during the Stall and Dresden units, the implementationsecond quarter of the SPP Market and change in the dispatch of AEP’s natural gas fleet resulted in a decreased natural gas-fired generation.  Despite the availability of natural gas due to the increased shale supply, the U.S. pipeline infrastructure remains a limiting factor in the expansion of natural gas-fired generation.2016. Several of AEP’s natural gas-fired power plants are connected to at least two pipelines however, which allow greater access to competitive supplies and improvesimprove delivery reliability.

Nuclear

I&M has made commitments to meet the current nuclear fuel requirements of the Cook Plant.  I&M has made and will make purchases of uranium in various forms in the spot, short-term and mid-term markets.  I&M also continues to lease a portion of its nuclear fuel.

For purposes of the storage of high-level radioactive waste in the form of spent nuclear fuel, I&M completed modifications to its spent nuclear fuel storage pool more than 10 years ago.  I&M entered into an agreement to provide for onsite dry cask storage of spent nuclear fuel to permit normal operations to continue.  I&M is scheduled to conduct further dry cask loading and storage projects on an ongoing periodic basis.  I&M completed its initial loading of spent nuclear fuel into the dry casks in 2012, which consisted of 12 casks (32 spent nuclear fuel assemblies contained within each).  The second loading of spent nuclear fuel into dry casks was completed in 2015, which consisted of 16 casks. The third dry cask loading is expected to be completedoccur in 2015.2018.

Nuclear Waste and Decommissioning

As the owner of the Cook Plant, I&M has a significant future financial commitment to dispose of spent nuclear fuel and decommission and decontaminate the plant safely.  The cost to decommission a nuclear plant is affected by NRC regulations and the spent nuclear fuel disposal program.  The most recent decommissioning cost study was completed in 2012.  In it, the2015.  The estimated cost of decommissioning and disposal of low-level radioactive waste for the Cook Plant ranged from $1.3 billion to $1.7was $1.6 billion in 20122015 non-discounted dollars.  As of December 31, 2014,2016, the total decommissioning trust fund balance for the Cook Plant was approximately $1.8$1.9 billion. The balance of funds available to eventually decommission Cook Plant will differ based on contributions and investment returns.  The ultimate cost of retiring the Cook Plant may be materially different from estimates and funding targets as a result of the:

Type of decommissioning plan selected.
Escalation of various cost elements (including, but not limited to, general inflation and the cost of energy).
Further development of regulatory requirements governing decommissioning.
Technology available at the time of decommissioning differing significantly from that assumed in studies.
Availability of nuclear waste disposal facilities.
Availability of a United States Department of Energy facility for permanent storage of spent nuclear fuel.

Accordingly, management is unable to provide assurance that the ultimate cost of decommissioning the Cook Plant will not be significantly different than current projections.  WeAEP will seek recovery from customers through our regulated rates if actual decommissioning costs exceed our projections.  See Note 6 to the consolidated financial statements, entitled Commitments, Guarantees and Contingencies under the heading Nuclear Contingencies, included in the 20142016 Annual Reports, for information with respect to nuclear waste and decommissioning.

Low-Level Radioactive Waste

The Low-Level Waste Policy Act of 1980 mandates that the responsibility for the disposal of low-level radioactive waste rests with the individual states.  Low-level radioactive waste consists largely of ordinary refuse and other items that have come in contact with radioactive materials.  Michigan does not currently have a disposal site for such waste available.  I&M cannot predict when such a site may be available. However, the states of Utah and Texas have licensed low level radioactive waste disposal sites which currently accept low level radioactive waste from Michigan waste generators.  There is currently no set date limiting I&M’s access to either of these facilities.  The Cook Plant has a facility onsite designed specifically for the storage of low level radioactive waste.  In the event that low level radioactive waste disposal facility access becomes unavailable, then low level radioactive waste can be stored onsite at this facility.

Counterparty Risk Management

The Vertically Integrated Utilities segment also sells power and enters into related energy transactions with wholesale customers and other market participants. As a result, counterparties and exchanges may require cash or cash related instruments to be deposited on transactions as margin against open positions.  As of December 31, 2016, counterparties posted approximately $9 million in cash, cash equivalents or letters of credit with AEPSC for the benefit of AEP’s public utility subsidiaries (while, as of that date, AEP’s public utility subsidiaries posted approximately$57 million with counterparties and exchanges).  Since open trading contracts are valued based on market prices of various commodities, exposures change daily.  See Management’s Discussion and Analysis of Financial Condition and Results of Operations, included in the 2016 Annual Reports, under the heading entitled Quantitative and Qualitative Disclosures About Market Risk for additional information.



Certain Power Agreements

I&M

The Unit Power Agreement between AEGCo and I&M, dated March 31, 1982, provides for the sale by AEGCo to I&M of all the capacity (and the energy associated therewith) available to AEGCo at the Rockport Plant.  Whether or not power is available from AEGCo, I&M is obligated to pay a demand charge for the right to receive such power (and an energy charge for any associated energy taken by I&M).  The agreement will continue in effect until the last of the lease terms of Unit 2 of the Rockport Plant hashave expired (currently December 2022) unless extended in specified circumstances.

Pursuant to an assignment between I&M and KPCo, and a unit power agreement between AEGCo and KPCo, AEGCo sells KPCo 30% of the capacity (and the energy associated therewith) available to AEGCo from both units of the Rockport Plant.  KPCo has agreed to pay to AEGCo the amounts that I&M would have paid AEGCo under the terms of the Unit Power Agreement between AEGCo and I&M for such entitlement.  The KPCo unit power agreement expires in December 2022.

OVEC

AEP and several nonaffiliated utility companies jointly own OVEC.  The aggregate equity participation of AEP in OVEC is 43.47%.  Until 2001, OVEC supplied from its generation capacityUnder the Inter-Company Power Agreement, which defines the rights of the owners and sets the power requirementsparticipation ratio of a uranium enrichment plant near Portsmouth, Ohio owned byeach, the United States Department of Energy.  The sponsoring companies are entitled to receive and are obligated to pay for all OVEC capacity (approximately 2,200 MW)2,400 MWs) in proportion to their respective power participation ratios.  The aggregate power participation ratio of APCo, I&M and OPCo is 43.47%.  The Inter-Company Power Agreement terminates in June 2040. The proceeds from the sale of power by OVEC are designed to be sufficient for OVEC to meet its operating expenses and fixed costs and to provide a return on its equity capital.  The Inter-Company Power Agreement, which defines the rights of the owners and sets the power participation ratio of each, was extended by the owners in 2011 from the termination date of March 2026 until June 2040.  AEP and the other owners have authorized environmental investments related to their ownership interests.  OVEC financed capital expenditures totaling $1.3 billion in connection with the engineering and construction of flue gas desulfurization projects and the associated scrubber waste disposal landfills at its two generation plants through debt issuances, including tax-advantaged debt issuances.  Both OVEC generation plants are operating with the new environmental controls in service.  OPCo attempted to assign its rights and obligations under the Inter-Company Power Agreement to an affiliate as part of its transfer of its generation assets and liabilities in keeping with corporate separation required by Ohio law.  OPCo failed to obtain the consent to assignment from the other owners of OVEC and therefore filed a request with the PUCO seeking authorization to maintain its ownership of OVEC. In December 2013, the PUCO approved OPCo’s request, subject to the condition that energy from the OVEC entitlements are sold into the day-ahead or real-time PJM energy markets, or on a forward basis through a bilateral arrangement. OPCo has filed an application withIn November 2016, the PUCO approved OPCo’s request to approve a purchasedcost-based purchased power agreement (PPA) rider, effective in January 2017, that would allow retail customers to receive a rate stabilizing charge or credit by hedging market-based prices with a cost-based purchase power agreement.  The PPA would initially be based upon OPCo'sOPCo’s contractual entitlement under the Inter-Company Agreement which is approximately 20% of OVEC's capacityOVEC’s capacity. Some parties filed a rehearing challenge to the PUCO decision which was denied. Separately, OPCo filed a proposal to replace the PPA rider with a bypassable rate mechanism that involves serving non-shopping load with the OVEC contractual entitlement, which remains pending at this time..



ELECTRIC DELIVERY

General

Other than AEGCo, AEP’s vertically integrated public utility subsidiaries own and operate transmission and distribution lines and other facilities to deliver electric power.  See Item 2 – Properties for more information regarding the transmission and distribution lines.  Most of the transmission and distribution services are sold to retail customers of AEP’s vertically integrated public utility subsidiaries in their service territories.  These sales are made at rates approved by the state utility commissions of the states in which they operate, and in some instances, approved by the FERC.  See Item 11. Business – Vertically Integrated Utilities – Regulation – Rates.  The FERC regulates and approves the rates for both wholesale transmission transactions and wholesale generation contracts.  The use and the recovery of costs associated with the transmission assets of the AEP vertically integrated public utility subsidiaries are subject to the rules, principles, protocols and agreements in place with PJM and SPP, and as approved by the FERC. See Item 11. Business – Vertically Integrated Utilities – Regulation – FERC.  As discussed below, some transmission services also are separately sold to non-affiliated companies.

Other than AEGCo, AEP’s vertically integrated public utility subsidiaries hold franchises or other rights to provide electric service in various municipalities and regions in their service areas.  In some cases, these franchises provide the utility with the exclusive right to provide electric service.service within a specific territory.  These franchises have varying provisions and expiration dates.  In general, the operating companies consider their franchises to be adequate for the conduct of their business.  For a discussion of competition in the sale of power, see Item 11. Business – Vertically Integrated Utilities – Competition.

The use and the recovery of costs associated with the transmission assets of the AEP vertically integrated public utility subsidiaries are subject to the rules, principles, protocols and agreements in place with PJM, SPP and ERCOT, and as approved by the FERC.

Transmission Agreement

APCo, I&M, KGPCo, KPCo and WPCo own and operate transmission facilities that are used to provide transmission service under the PJM OATT and are parties to the TA.  OPCo, a subsidiary in ourAEP’s Transmission and Distribution Utilities segment, is also a party to the TA.  The TA defines how the parties to the agreement share the revenues associated with their transmission facilities and the costs of transmission service provided by PJM.  The TA has been approved by the FERC.

The following table shows the net charges allocated among the certain parties to the TA during the years ended December 31, 2014, 2013 and 2012:

TCA, OATT, and ERCOT Protocols

PSO, SWEPCo and AEPSC are parties to the TCA.  Under the TCA, a coordinating committee is charged with the responsibility of (a) overseeing the coordinated planning of the transmission facilities of the parties to the agreement, including the performance of transmission planning studies, (b) the interaction of such subsidiaries with independent system operators and other regional bodies interested in transmission planning and (c) compliance with the terms of the OATT filed with the FERC and the rules of the FERC relating to such tariff.  Pursuant to the TCA, AEPSC has responsibility for monitoring the reliability of their transmission systems and administering the OATT on behalf of the other parties to the agreement.  The TCA also provides for the allocation among the parties of revenues collected for transmission and ancillary services provided under the OATT.  These allocations have been determined by the FERC-approved OATT for the SPP.

The following table shows the net (credits) or charges allocated pursuant to the TCA and SPP OATT protocols as described above for the years ended December 31, 2014, 2013 and 2012:

Transmission Services for Non-Affiliates

In addition to providing transmission services in connection with their own power sales, AEP’s vertically integrated public utility subsidiaries through RTOs also provide transmission services for non-affiliated companies.  See Item 1 – Vertically Integrated Utilities – Electric Transmission and Distribution – Regional Transmission Organizations, below.  Transmission of electric power by AEP’s public utility subsidiaries is regulated by the FERC.

Coordination of East and West Zone Transmission

AEP’s System Transmission Integration Agreement was terminated effective June 1, 2014. It provided for the integration and coordination of the planning, operation and maintenance of the transmission facilities of AEP East Companies and AEP West Companies.  The System Transmission Integration Agreement functioned as an umbrella agreement in addition to the TA and the TCA.  AEP’s System Transmission Integration Agreement contained two service schedules that governed:

The allocation of transmission costs and revenues.
The allocation of third-party transmission costs and revenues and System dispatch costs.

The System Transmission Integration Agreement contemplated that additional service schedules may be added as circumstances warrant.

Regional Transmission Organizations

AEGCo, APCo, I&M, KGPCo, KPCo and WPCo are members of PJM, and PSO and SWEPCo are members of the SPP (both FERC-approved RTOs).  RTOs operate, plan and control utility transmission assets in a manner designed to provide open access to such assets in a way that prevents discrimination between participants owning transmission assets and those that do not.



REGULATION

General

AEP’s vertically integrated public utility subsidiaries’ retail rates and certain other matters are subject to traditional cost-based regulation by the state utility commissions.  AEP’s vertically integrated public utility subsidiaries are also subject to regulation by the FERC under the Federal Power Act with respect to wholesale power and transmission service transactions.  I&M is subject to regulation by the NRC under the Atomic Energy Act of 1954, as amended, with respect to the operation of the Cook Plant.  AEP and its vertically integrated public utility subsidiaries are also subject to the regulatory provisions of EPACT, much of which is administered by the FERC.

Rates

Historically, state utility commissions have established electric service rates on a cost-of-service basis, which is designed to allow a utility an opportunity to recover its cost of providing service and to earn a reasonable return on its investment used in providing that service.  A utility’s cost of service generally reflects its operating expenses, including operation and maintenance expense, depreciation expense and taxes.  State utility commissions periodically adjust rates pursuant to a review of (a) a utility’s adjusted revenues and expenses during a defined test period and (b) such utility’s level of investment.  Absent a legal limitation, such as a law limiting the frequency of rate changes or capping rates for a period of time, a state utility commission can review and change rates on its own initiative.  Some states may initiate reviews at the request of a utility, customer, governmental or other representative of a group of customers.  Such parties may, however, agree with one another not to request reviews of or changes to rates for a specified period of time.

Public utilities have traditionally financed capital investments until the new asset is placed in service.  Provided the asset was found to be a prudent investment, it was then added to rate base and entitled to a return through rate recovery.  Given long lead times in construction, the high costs of plant and equipment and volatile capital markets, we aremanagement is actively pursuing strategies to accelerate rate recognition of investments and cash flow.  AEP representatives continue to engage our state commissioners and legislators on alternative ratemaking options to reduce regulatory lag and enhance certainty in the process.  These options include pre-approvals, a return on construction work in progress, rider/trackers, formula rates and the inclusion of future test-year projections into rates.


20



The rates of AEP’s vertically integrated public utility subsidiaries are generally based on the cost of providing traditional bundled electric service (i.e., generation, transmission and distribution service).  Historically, the state regulatory frameworks in the service area of the AEP vertically integrated public utility subsidiaries reflected specified fuel costs as part of bundled (or, more recently, unbundled) rates or incorporated fuel adjustment clauses in a utility’s rates and tariffs.  Fuel adjustment clauses permit periodic adjustments to fuel cost recovery from customers and therefore provide protection against exposure to fuel cost changes.

The following state-by-state analysis summarizes the regulatory environment of certain major jurisdictions in which AEP operates.AEP’s vertically integrated public utility subsidiaries operate.  Several public utility subsidiaries operate in more than one jurisdiction.  See Note 4 to the consolidated financial statements, entitled Rate Matters, included in the 20142016 Annual Reports, for more information regarding pending rate matters.

Indiana

I&M provides retail electric service in Indiana at bundled rates approved by the IURC, with rates set on a cost-of-service basis.  Indiana provides for timely fuel and purchased power cost recovery through a fuel cost recovery mechanism.



Oklahoma

PSO provides retail electric service in Oklahoma at bundled rates approved by the OCC.  PSO’s rates are set on a cost-of-service basis.  Fuel and purchased energy costs above or below the amount included in base rates are recovered or refunded by applying fuel adjustment and other factors to retail kilowatt-hour sales.  The factors are generally adjusted annually and are based upon forecasted fuel and purchased energy costs.  Over or under collections of fuel and purchased energy costs for prior periods are returned to or recovered from customers in the year following when new annual factors are established.

Virginia

APCo currently provides retail electric service in Virginia at unbundled generation and distribution rates, currently frozen, approved by the Virginia SCC.  Virginia generally allows for timely recovery of fuel costs through a fuel adjustment clause.  Transmission services are provided at OATT rates based on rates established by the FERC.  In addition to base rates and fuel cost recovery, APCo is permitted to recover a variety of costs through rate adjustment clauses.clauses including transmission services provided at OATT rates based on rates established by the FERC.

West Virginia

APCo and WPCo provide retail electric service at bundled rates approved by the WVPSC, with rates set on a combined cost-of-service basis.  West Virginia generally allows for timely recovery of fuel costs through an expanded net energy cost which trues-up to actual expenses.

FERC

Under the Federal Power Act, the FERC regulates rates for interstate power sales at wholesale, transmission of electric power, accounting and other matters, including construction and operation of hydroelectric projects.  The FERC regulations require AEP’s vertically integrated public utility subsidiaries to provide open access transmission service at FERC-approved rates.rates, and AEP has approved cost-based formula transmission rates on file at FERC.  The FERC also regulates unbundled transmission service to retail customers.  TheIn addition, the FERC also regulates the sale of power for resale in interstate commerce by (a) approving contracts for wholesale sales to municipal and cooperative utilities and (b) granting authority to public utilities to sell power at wholesale at market-based rates upon a showing that the seller lacks the ability to improperly influence market prices.  AEP’s vertically integrated public utility subsidiaries have market-based rate authority from the FERC, under which much of their wholesale marketing activity takes place.  The FERC requires each public utility that owns or controls interstate transmission facilities to, directly or through an RTO, to file an open access network and point-to-point transmission tariff that offers services comparable to the utility’s own uses of its transmission system.  The FERC also requires all

21



transmitting utilities, directly or through an RTO, to establish an Open Access Same-time Information System, which electronically posts transmission information such as available capacity and prices, and requires utilities to comply with Standards of Conduct that prohibit utilities’ transmission employees from providing non-public transmission information to the utility’s marketing employees.

The FERC oversees RTOs, entities created to operate, plan and control utility transmission assets.  FERC Order 2000 also prescribes certain characteristics and functions of acceptable RTO proposals.  AEGCo, APCo, I&M, KGPCo, KPCo and WPCo are members of PJM.  PSO and SWEPCo are members of SPP.

The FERC has jurisdiction over the issuances of securities of most of ourAEP’s public utility subsidiaries, the acquisition of securities of utilities, the acquisition or sale of certain utility assets and mergers with another electric utility or holding company.  In addition, both the FERC and state regulators are permitted to review the books and records of any company within a holding company system.  EPACT gives the FERC increased utility merger oversight.



COMPETITION

The vertically integrated public utility subsidiaries of AEP, like the electric industry generally, face competition in the sale of available power on a wholesale basis, primarily to other public utilities and power marketers.  The Energy Policy Act of 1992 was designed, among other things, to fosterFederal policy generally fosters competition in the wholesale market by creating a generation market with fewer barriers to entry and mandatingmandates that all generators have equal access to transmission services.  As a result, there are more generators able to participate in this market.  The principal factors in competing for wholesale sales are price (including fuel costs), reliability of service, and availability of capacity and power and reliability of service.power.

Technology advancements, increased demand for clean energy, changing consumer behaviors, low-priced and abundant natural gas, and regulatory and public policy reforms are among the catalysts for transformation within the industry that impact competition for AEP’s vertically integrated public utility subsidiaries. AEP’s vertically integrated public utility subsidiaries also compete with self-generation and with distributors of other energy sources, such as natural gas, fuel oil, renewables and coal, within their service areas.  The primary factors in such competition are price, reliability of service and the capability of customers to utilize alternative sources of energy other than electric power. With respect to competing generators and self-generation, the public utility subsidiaries of AEP believe that they generallycurrently maintain a competitive position. With respect

Changes in regulatory policies and advances in newer technologies for batteries or energy storage, fuel cells, microturbines, wind turbines and photovoltaic solar cells are reducing costs of new technology to alternative sourceslevels that are making them competitive with some central station electricity production.  The costs of photovoltaic solar cells in particular have continued to become increasingly competitive. The ability to maintain relatively low cost, efficient and reliable operations and to provide cost-effective programs and services to customers are significant determinants of AEP’s competitiveness.

While the adoption rate of distributed generation in AEP’s service areas has not reached the levels seen in other parts of the country, AEP’s vertically integrated utility companies are focused on providing customers with more choices by working with regulators and policymakers to expand, and potentially accelerate, renewable energy theofferings. Such additional customer choices consider not only long-term cost, but are also focused on expanding resource diversity. This includes proposed new revenue structures that enable deployment of advanced technologies and resources. In 2015, AEP formed an Enterprise Technology Council to develop and deploy new programs and services designed to receive regulatory support. The vertically integrated public utility subsidiaries of AEP believe that the reliability of their service, and the limited ability of customers to substitute other cost-effectiveeconomical sources for electric power and their ability to cost-effectively deploy advanced technologies, such as solar, on a large scale place them in a favorable competitive position, even though their prices may be higher than the costs of some other sources of energy.position.

SignificantIn the event that alternative generation resources are mandated, subsidized or encouraged through legislation or regulationor otherwise are economically competitive and added to the available generation supply, such resources could displace a higher marginal cost fossil plant, which could reduce the price at which market participants sell their electricity. These events could cause AEP to retire generating capacity prior to the end of its estimated useful life.  AEP typically recovers undepreciated plant balances and associated operating costs, each including a return, from customers through regulated rates in regulated jurisdictions.  Failure to recover these costs could reduce future net income and cash flows and possibly harm financial condition.

Recent changes in the global economy have led to increased price competition for many industrial customers in the United States, including those served by the AEP System. Some of these industrial customers have requested price reductions from their suppliers of electric power.  In addition, industrialIndustrial customers that are downsizing or reorganizing often close a facility based upon its costs, which may include, among other things, the cost of electric power.  The vertically integrated public utility subsidiaries of AEP cooperatework with such customers to meet their business needs through, forneeds. For example, providing various off-peak or interruptible supply options may be provided pursuant to tariffs filed with, and approved by, the various state commissions. Occasionally, these rates are negotiatedThe vertically integrated public utility subsidiaries of AEP also work with customers that seek to source more of their electric power from renewable resources. Depending on the customer, and then filed with the state commissions for approval.jurisdiction, customers may have access to green power tariffs. In other instances, AEP purchases renewable power that is available to all customers in a specific jurisdiction.


SEASONALITY

The sale of electric power is generally a seasonal business.  In many parts of the country, demand for power peaks during the hot summer months, with market prices also peaking at that time.  In other areas, power demand peaks during the winter.  The pattern of this fluctuation may change due to the nature and location of AEP’s facilities and the terms of power sale contracts into which AEP enters.  In addition, AEP has historically sold less power, and consequently earned less income, when weather conditions are milder. Unusually mild weather in the future could diminish AEP’s results of operations and may impact its financial condition.operations. Conversely, unusually extreme weather conditions could increase AEP’s results of operations.

TRANSMISSION AND DISTRIBUTION UTILITIES

GENERAL

This segment consists of the transmission and distribution of electricity for sale to retail and wholesale customers through assets owned and operated by OPCo, TCCAEP Texas and TNC.OPCo. OPCo is engaged in the transmission and distribution of electric power to approximately 1,466,0001,472,000 retail customers in Ohio.  TCCAEP Texas is engaged in the transmission and distribution of electric power to approximately 817,000 retail customers through REPs in southern Texas. TNC is engaged in the transmission and distribution of electric power to approximately 189,0001,024,000 retail customers through REPs in west, central and centralsouthern Texas.

AEP’s transmission and distribution utility subsidiaries own and operate transmission and distribution lines and other facilities to deliver electric power.  See Item 2 – Properties for more information regarding the transmission and distribution lines.  Most of the transmission and distribution services are sold to retail customers of AEP’s transmission and distribution utility subsidiaries in their service territories.  These sales are made at rates approved by the PUCT for TCC and TNCAEP Texas and by the PUCO and the FERC for OPCo.  The FERC regulates and approves the rates for wholesale transmission transactions.  As discussed below, some transmission services also are separately sold to non-affiliated companies.

AEP’s transmission and distribution utility subsidiaries hold franchises or other rights to provide electric service in various municipalities and regions in their service areas.  In some cases, these franchises provide the utility with the exclusive right to provide electric service.  These franchises have varying provisions and expiration dates.  In general, the operating companies consider their franchises to be adequate for the conduct of their business.

The use and the recovery of costs associated with the transmission assets of the AEP transmission and distribution utility subsidiaries are subject to the rules, protocols and agreements in place with PJM and ERCOT, and as approved by the FERC.  In addition to providing transmission services in connection with power sales in their service areas, AEP’s transmission and distribution utility subsidiaries through RTOs also provide transmission services for non-affiliated companies.

Transmission Agreement

OPCo, together with APCo, I&M, KGPCo, KPCo and WPCo, is a party to the TA.  The TA defines how the parties to the agreement share the cost of their transmission facilities.  The TA has been approved by the FERC.  OPCo’s net charges allocated to it under the TA during the years ended December 31, 2014, 2013 and 2012 were $17 million, $8.9 million and $6.1 million, respectively.

Regional Transmission Organizations

OPCo is a member of PJM, a FERC-approved RTO.  RTOs operate, plan and control utility transmission assets in a manner designed to provide open access to such assets in a way that prevents discrimination between participants owning transmission assets and those that do not.  TCC and TNC are membersAEP Texas is a member of ERCOT.

REGULATION

OPCo provides distribution and transmission services to retail customers within its service territory at cost-based rates approved by the PUCO or by the FERC.  TCC and TNC provideAEP Texas provides transmission and distribution service on a cost-of-service basis at rates approved by the PUCT and wholesale transmission service under tariffs approved by the FERC consistent with PUCT rules.  Transmission and distribution rates are established on a cost-of-service basis, which is designed to allow a utility an opportunity to recover its cost of providing service and to earn a reasonable return on its investment used in providing that service.  The cost of service generally reflects operating expenses, including operation and maintenance expense, depreciation expense and taxes.  Utility commissions periodically adjust rates pursuant to a review of (a) a utility’s adjusted revenues and expenses during a defined test period and (b) such utility’s level of investment.

FERC

Under the Federal Power Act, the FERC regulates rates for transmission of electric power, accounting and other matters.  The FERC regulations require AEP to provide open access transmission service at FERC-approved rates.rates, and it has approved cost-based formula transmission rates on file at FERC.  The FERC also regulates unbundled transmission service to retail customers.  The FERC requires each public utility that owns or controls interstate transmission facilities to, directly or through an RTO, file an open access network and point-to-point transmission tariff that offers services comparable to the utility’s own uses of its transmission system.  The FERC also requires all transmitting utilities, directly or through an RTO, to establish an Open Access Same-time Information System, which electronically posts transmission information such as available capacity and prices, and requires utilities to comply with Standards of Conduct that prohibit utilities’ transmission employees from providing non-public transmission information to the utility’s marketing employees. In addition, both the FERC and state regulators are permitted to review the books and records of any company within a holding company system.  EPACT gives the FERC increased utility merger oversight.

SEASONALITY

The delivery of electric power is generally a seasonal business.  In many parts of the country, demand for power peaks during the hot summer months.  In other areas, power demand peaks during the winter months.  The pattern of this fluctuation may change due to the nature and location of AEP’s transmission and distribution facilities.  In addition, AEP transmission and distribution has historically delivered less power, and consequently earned less income, when weather conditions are milder.  UnusuallyIn Texas, and to a lesser extent, in Ohio, unusually mild weather in the future could diminish AEP transmission and distribution’sAEP’s results of operations and may impact its financial condition.operations.  Conversely, unusually extreme weather conditions could increase AEP transmission and distribution’sAEP’s results of operations.

GENERATION & MARKETING

GENERAL

Our Generation & Marketing segment subsidiaries consist of competitive nonutility generating assets, a wholesale energy trading and marketing business and a retail supply and energy management business.  The largest subsidiary in our Generation & Marketing segment is AGR.  On December 31, 2013, AGR acquired the generation assets and related liabilities at net book value of OPCo in a series of transactions approved by the PUCO and the FERC.  AGR transferred a portion of the generation assets and liabilities at net book value that it received to APCo and KPCo, and, in 2015 to WPCo.  As a result of these transactions, AGR owns 9,159 MW of generating capacity, with rights to an additional 1,186 MW pursuant to a unit power agreement (see below).  Other subsidiaries in this segment own or have the right to receive power from additional generation assets.  See Item 2 – Properties for more information regarding the generation assets of the Generation & Marketing segment. AGR is a competitive generation subsidiary.

With respect to our wholesale energy trading and marketing business, we enter into short and long-term transactions to buy or sell capacity, energy and ancillary services primarily in ERCOT, MISO and PJM.  We sell power into the market and engage in power, natural gas, coal and emissions allowances risk management and trading activities.  

These activities primarily involve the purchase and sale of electricity (and to a lesser extent, natural gas, coal and emissions allowances) under forward contracts at fixed and variable prices.  These contracts include physical transactions, exchange-traded futures, and to a lesser extent, over-the-counter swaps and options.  The majority of forward contracts are typically settled by entering into offsetting contracts.  These transactions are executed with numerous counterparties or on exchanges.

With respect to our retail supply and energy management business, our subsidiary AEP Energy is a retail energy supplier that supplies electricity to residential, commercial, and industrial customers.  AEP Energy provides an array of energy solutions and is operating in Illinois, Pennsylvania, Delaware, Maryland, New Jersey, Ohio and Washington, D.C.  AEP Energy also provides demand-side management solutions nationwide.  AEP Energy had approximately 240,000 customer accounts as of December 31, 2014.

REGULATION

AGR is a public utility under the Federal Power Act, and is subject to FERC’s exclusive ratemaking jurisdiction over wholesale sales of electricity and the transmission of electricity in interstate commerce. Under the Federal Power Act, FERC has the authority to grant or deny market-based rates for sales of energy, capacity and ancillary services to ensure that such sales are just and reasonable.  FERC granted AGR market-based rate authority in December 2013.  FERC’s jurisdiction over ratemaking also includes the authority to suspend the market-based rates of utilities (including AGR, which is a public utility as defined by the FERC) and set cost-based rates if FERC subsequently determines that such utility can exercise market power, create barriers to entry or engage in abusive affiliate transactions.  As a condition to the order granting AGR market-based rate authority, every three years AGR is required to file a market power update to show that it continues to meet FERC’s standards with respect to generation market power and other criteria used to evaluate whether it continues to qualify for market-based rates.  Other matters subject to FERC jurisdiction include, but are not limited to, review of mergers; and dispositions of jurisdictional facilities and acquisitions of securities of another public utility or an existing operational generating facility.

Specific operations of AGR are also subject to the jurisdiction of various other Federal, state, regional and local agencies, including Federal and state environmental protection agencies.  We are also regulated by the PUCT for transactions inside ERCOT.  Additionally, AGR is subject to mandatory reliability standards promulgated by the North American Electric Reliability Corporation, with the approval of FERC. 

COMPETITION

The generation and marketing subsidiaries of AEP face competition for the sale of available power, capacity and ancillary services.  The principal factors impacting us are electricity and fuel prices, new market entrants, construction or retirement of generating assets by others and technological advances in power generation. It is possible that changes in regulatory policies or advances in newer technologies for batteries or energy storage, fuel cells, microturbines, windmills and photovoltaic solar cells will reduce costs of new technology to levels that are equal to or below that of most central station electricity production.  Our ability to maintain relatively low cost, efficient and reliable operations is a significant determinate of our competitiveness.

With over 70% of our generation fleet fueled by coal, our overall competitive position is impacted by the price of natural gas relative to coal.  While higher relative natural gas prices generally favor our competitive position, lower relative natural gas prices will favor our competitors that have a higher concentration of natural gas fueled generation.  Other factors impacting our competitiveness include environmental regulation, transmission congestion or transportation constraints at or near our generation facilities, inoperability or inefficiencies, outages and deactivations and retirements at our generation facilities.

SEASONALITY

The sale of electric power is generally a seasonal business.  In many parts of the country, demand for power peaks during the hot summer months, with market prices also peaking at that time.  In other areas, power demand peaks during the winter months.  The pattern of this fluctuation may change.

Counterparty Risk Management

Counterparties and exchanges may require cash or cash related instruments to be deposited on these transactions as margin against open positions.  As of December 31, 2014, counterparties posted approximately $26 million in cash, cash equivalents or letters of credit with AEP for the benefit of AEP’s generation and marketing subsidiaries (while, as of that date, AEP’s generation and marketing subsidiaries posted approximately$220 million with counterparties and exchanges).  Since open trading contracts are valued based on market prices of various commodities, exposures change daily.  See Management’s Discussion and Analysis of Financial Condition and Results of Operations, included in the 2014 Annual Reports, under the heading entitled Quantitative and Qualitative Disclosures About Market Risk for additional information.

Fuel Supply

The table shows the sources of fossil fuel used, on a heat basis, by AGR:
2014
Coal 88%
Natural Gas   12%
Fuel Oil and other< 1%
A price increase/decrease in one or more fuel sources relative to other fuels may result in the decreased/increased use of other fuels.

Coal and Consumables
AGR procures coal and consumables needed to burn the coal under a combination of purchasing arrangements including long-term and spot contracts with various producers and coal trading firms.  As contracts expire, they are replaced, as needed, with contracts at market prices. Coal and consumable inventories remain adequate to meet generation requirements.
Management believes that AGR will be able to secure and transport coal and consumables of adequate quality and in adequate quantities to operate their coal fired units.  AGR, through contracts, ownership and leases has the ability to adequately move and store coal and consumables for use in our generating facilities. AGR plants consumed 16.1 million tons of coal in 2014.

The coal supplies at AGR plants vary from time to time depending on various factors, including, but not limited to, demand for electric power, unit outages, transportation infrastructure limitations, space limitations, plant coal consumption rates, coal quality, availability of acceptable coals, labor issues and weather conditions, which may interrupt production or deliveries. As of December 31, 2014, AGR’s coal inventory was adequate to meet the generation demand of the coal fleet.

Natural Gas

Despite the availability of natural gas due to the increased shale supply, the U.S. pipeline infrastructure remains a limiting factor in the expansion of natural gas-fired generation.  A portfolio of term, monthly, seasonal firm and daily peaking purchase and transportation agreements (that are entered into on a competitive basis and based on market prices) supplies natural gas requirements for each plant, as appropriate. AGR plants consumed 50 billion cubic feet of natural gas in 2014, an increase of approximately 9% from 2013.

Certain Power Agreements

AEGCo

The Unit Power Agreement between AEGCo and AGR (assigned from OPCo) dated March 15, 2007, provides for the sale by AEGCo to AGR of all the capacity and associated unit contingent energy and ancillary services available to AGR from the Lawrenceburg Plant, a 1,186 MW natural gas-fired unit owned by AEGCo.  AGR is obligated to pay a capacity charge (whether or not power is available from the Lawrenceburg Plant), and the fuel, operating and maintenance charges associated with the energy dispatched by AGR, and to reimburse AEGCo for other costs associated with the operation and ownership of the Lawrenceburg Plant.  The agreement will continue in effect until December 31, 2017 unless extended.

OPCo

Pursuant to a Power Supply Agreement (PSA) between AGR and OPCo, AGR supplies capacity for OPCo’s switched and non-switched retail load for the period January 1, 2014 through May 31, 2015.  AGR also supplied the energy needs of OPCo’s non-switched retail load that was not acquired through auctions from January 1, 2014 through December 31, 2014 under the PSA.

Other

As of December 31, 2014, the assets utilized in this segment included approximately 310 MW of company-owned domestic wind power facilities, 177 MW of domestic wind power from long-term purchase power agreements and 355 MW of coal-fired capacity which was obtained through an agreement effective through 2027 that transfers TNC’s interest in the Oklaunion power station to AEP Energy Partners, Inc.  The power obtained from the Oklaunion power station is marketed and sold in ERCOT.


AEP TRANSMISSION HOLDCO (AEPTHCO)

GENERAL

AEPTHCo is a holding company for (a) AEP’s transmission joint ventures and (b) AEPTCo, which is the direct holding company for the seven wholly-owned FERC-regulated transmission-only electric utilities (Transcos) listed below, each of which is geographically aligned with our existing utility operating companies.  State Transcos and (b) AEP’s Transmission Joint Ventures.

AEPTCo

AEPTCo TRANSCOS

AEP East Transmission Companies (all located within PJM)wholly owns the State Transcos:

AEP Appalachian Transmission Company, Inc. (APTCo) (covering Virginia)
AEP Indiana Michigan Transmission Company, Inc. (IMTCo)
AEP Kentucky Transmission Company, Inc. (KTCo)
AEP Ohio Transmission Company, Inc. (OHTCo)
AEP West Virginia Transmission Company, Inc. (WVTCo)

AEP West Transmission Companies (all located within SPP)

AEP Oklahoma Transmission Company, Inc. (OKTCo)
AEP Southwestern Transmission Company, Inc. (SWTCo) (covering Louisiana)


27



Transmission development through the Transcos is primarily driven by:

Improvements to local area reliability by upgrading, rebuilding or replacing existing, aging infrastructure.
Construction of new facilities to support customer points of delivery, generation interconnections, new facilities to provide transmission service directed by the RTOs, and new facilities required to maintain grid reliability.
Projects assigned as a result of the regional planning initiatives conducted by PJM and SPP.  PJM and SPP identify the need for transmission in support of regional reliability, congestion reduction and the integration of and retirement of generation facilities.

The Transcos develop, own and operate transmission assets that are physically connected to AEP’s existing system.  They are regulated for rate-making purposes exclusively by the FERC and employ a forward-looking formula rate tariff design.  TheState Transcos are independent of, but respectively overlay, the following of AEP’s existing vertically integratedelectric utility operating companies: APCo, I&M, KPCo, KGPCo, OPCo, PSO, SWEPCo, and WPCo. The State Transcos develop, own, operate, and maintain their respective transmission assets. Assets of the State Transcos interconnect to transmission facilities owned by the aforementioned operating companies and unaffiliated transmission owners within the transmission operationsfootprints of OPCo.PJM and SPP. APTCo, IMTCo, KTCo, OHTCo, and WVTCo are located within PJM. OKTCo and SWTCo are located within SPP.

IMTCo, KTCo, OHTCo, OKTCo, and WVTCo have received all necessary approvals for formation or did not require state commission approval to operate.  IMTCo, KTCo, OHTCo, OKTCo and WVTCo currently own and operate transmission assets or have assets under construction.  APTCo requires approval fromin their respective jurisdictions.  In December 2016, the Virginia SCC onand WVPSC granted consent for APCo and APTCo to enter into a project by project basis.  The APSC has denied SWTCo's application to operatejoint license agreement that will support APTCo investment in Arkansas.the state of Tennessee. An application for regulatory approval for SWTCo is under consideration in Louisiana.

The State Transcos are regulated for rate-making purposes exclusively by FERC and earn revenues through tariff rates charged for the use of their electric transmission systems.  The State Transcos establish transmission rates each year through formula rate filings with FERC.  The rate filings calculate the revenue requirement needed to cover the costs of operation and debt service and to earn an allowed return on equity.  These rates are then included in OATT for SPP and PJM.

The State Transcos own, operate, maintain and invest in transmission infrastructure in order to maintain and enhance system integrity and grid reliability, grid security, safety, reduce transmission constraints and facilitate interconnections of new generating resources and new wholesale customers, as well as enhance competitive wholesale electricity markets. A key part of AEP’s business is replacing and upgrading transmission facilities, assets and components of the existing AEP System as needed to maintain reliability.

The State Transcos provide the capability to replace and upgrade existing facilities. The State Transcos are geographically diverse and have assets in service or under construction across two RTOs and in six states, with additional states planned or pending approval. As of December 31, 2014, AEPTCo2016, the State Transcos had $1.8$4.1 billion of transmission assets in-service with plans to construct approximately $3$ 4.4 billion of additional transmission assets through 2017.2019. Management anticipates the need for extensive additional investment in transmission infrastructure within PJM and SPP to maintain the required level of grid reliability, resiliency, security and efficiency and to address an aging transmission infrastructure. Management also foresees the need to construct additional transmission facilities based on changes in generating resources, such as wind or solar projects, generation additions or retirements, and additional new customer interconnections.  AEP will continue its investment to enhance physical and cyber security of assets, and are also investing in improving the telecommunication network that supports the operation and control of the grid.

OurAEP’s joint ventures do not have employees.  Business services for the joint ventures are provided by AEPSC and other AEP subsidiaries and the joint venture partners. During 20142016 approximately 665598 AEPSC employees and 260292 operating company employees provided service to one or more joint ventures. The amount of service provided was equal to the service of approximately 195 full-time employees.

REGULATION

The State Transcos and joint venturesthe Transmission Joint Ventures located outside of ERCOT establish transmission rates annually through forward looking formula rate filings with the FERC pursuant to FERC-approved implementation protocols.  The protocols include a transparent, formal review process to ensure the updated transmission rates are prudently incurred and reasonably calculated.

The State Transcos’ and joint ventures’the Transmission Joint Ventures’ (where applicable) rates are included in the respective OATT for PJM and SPP.  An OATT is the FERC rate schedule that provides the terms and conditions for transmission and related services on a transmission provider’s transmission system.  The FERC requires transmission providers such as PJM and SPP to offer transmission service to all eligible customers (for example, load-serving entities, power marketers, generators and customers) on a non-discriminatory basis.

The FERC-approved formula rates establish the annual transmission revenue requirement (ATRR) and transmission service rates for transmission owners in annual rate base filings with FERC.  The formula rates establish rates for a one-year period based on the current projects in-service and proposed projects for a defined timeframe.  The formula rates also include a true-up calculation for the previous year’s billings, allowing for over- and over/under-recovery of the transmission owner’s ATRR.  PJM and SPP pay the transmission owners their ATRR for use of their facilities and bill transmission customers taking service under the PJM and SPP OATTs, based on the terms and conditions in the respective OATT for the service taken.

The formula rate mechanism allows for a return on equity of 11.49% based on a capital structure of up to 50% equity for the AEP East Transmission Companies.  The AEP West Transmission CompaniesAPTCo, IMTCo, KTCo, OHTCo and WVTCo.  OKTCo and SWTCo are allowed a return on equity of 11.20%11.2% based on a capital structure of up to 50% equity. The authorized returns on equity for the State Transcos are commensurate with the FERC-authorized returns on equity in the PJM and SPP OATTs, respectively, for AEP’s utility subsidiaries.

In October 2016, several parties filed a joint complaint with FERC claiming the base return on common equity used by various AEP affiliates in calculating formula transmission rates under the PJM OATT is excessive and should be reduced from 10.99% to 8.32%, effective upon the date of the complaint. In November 2016, AEP affiliates filed an application with the FERC to modify the FERC formula transmission rate calculation, including adjustments for certain tax issues and a switch from historic to estimated expenses with a proposed effective date of January 1, 2017. The rates will be implemented based upon the date provided in the pending FERC order, subject to refund.

In the annual rate basedbase filings described above, the State Transcos in aggregate filed rate base totals of $1,448 million$3.2 billion in 2014, $776 million2016, $2.3 billion for 20132015 and $283 million$1.4 billion for 2012.2014.  The total transmission revenue requirement filed in the ATRR, including prior year over/under recoveryunder-recovery of revenue and associated carrying charges, for 2016, 2015, and 2014 2013 and 2012 was $229$555 million, $107$363 million and $35$231 million, respectively.

The rates of ETT, which is located in ERCOT, are determined by the PUCT.  ETT sets its rates through a combination of base rate cases and interim Transmission Costs of Services (TCOS) filings.  ETT may file interim TCOS filings semi-annually to update its rates to reflect changes in its net invested capital.

Our joint venturesEffective March 2017, the Transmission Joint Ventures have approved returns on equity ranging from 9.96%9.6% to 12.8% based on equity capital structures ranging from 40% to 60%.


GENERATION & MARKETING

GENERAL

The AEP Generation & Marketing segment subsidiaries consist of competitive nonutility generating assets, a wholesale energy trading and marketing business and a retail supply and energy management business.  The largest subsidiary in the Generation & Marketing segment is AGR.  Through year end 2016 AGR owned 6,752 MWs of generating capacity, with rights to an additional 1,186 MWs pursuant to a unit power agreement (see below).  In January 2017, AGR sold 4,143 MWs of generation capacity to an unaffiliated third party and terminated the 1,186 MW unit power agreement. As a result of the sale, AGR currently owns 2,732 MWs of generating capacity. Other subsidiaries in this segment own or have the right to receive power from additional generation assets.  See Item 2 – Properties for more information regarding the generation assets of the Generation & Marketing segment. AGR is a competitive generation subsidiary.

With respect to wholesale energy trading and marketing business, AEP Generation & Marketing segment subsidiaries enter into short-term and long-term transactions to buy or sell capacity, energy and ancillary services in ERCOT, SPP, MISO and PJM.  These subsidiaries sell power into the market and engage in power, natural gas, coal and emissions allowances risk management and trading activities.  

These activities primarily involve the purchase and sale of electricity (and to a lesser extent, natural gas, coal and emissions allowances) under forward contracts at fixed and variable prices.  These contracts include physical transactions, exchange-traded futures, and to a lesser extent, over-the-counter swaps and options.  The majority of forward contracts are typically settled by entering into offsetting contracts.  These transactions are executed with numerous counterparties or on exchanges.

With respect to the retail supply and energy management business, AEP Energy is a retail energy supplier that supplies electricity and/or natural gas to residential, commercial, and industrial customers.  AEP Energy provides various energy solutions in Illinois, Pennsylvania, Delaware, Maryland, New Jersey, Ohio and Washington, D.C.  AEP Energy also provides demand-side management solutions nationwide.  AEP Energy had approximately 430,000 customer accounts as of December 31, 2016.

AEP Energy Supply LLC owns 311 MWs of wind capacity in Texas and sells its energy entitlement to third parties or liquidates at market. In 2016, AEP took several major steps in executing its strategic plan to develop and market a merchant distributed resource portfolio. AEP Renewables, LLC was formed in April 2016 to develop and/or acquire large scale renewable projects backed with long-term contracts with credit worthy counterparties. In 2016, AEP Renewables, LLC brought into service a 26 MW solar project in Utah. The company also owns a 62 MW solar project in Nevada that was brought into service in 2017.

AEP OnSite Partners, LLC works directly with wholesale and large retail customers to provide tailored solutions to reduce their energy costs based upon market knowledge, innovative applications of technology and deal structuring capabilities. The company targets opportunities in distributed solar, combined heat and power, energy storage, waste heat recovery, energy efficiency, peaking generation and other energy solutions that create value for customers. AEP OnSite Partners, LLC pursues and develops behind the meter projects with credit-worthy customers and appropriate agreements. As of December 31, 2016, AEP OnSite Partners, LLC owned projects operating in six states, including 15 MWs of installed solar capacity and another 21 MWs of solar projects under construction in five states.



REGULATION

AGR is a public utility under the Federal Power Act, and is subject to FERC’s exclusive ratemaking jurisdiction over wholesale sales of electricity and the transmission of electricity in interstate commerce. Under the Federal Power Act, FERC has the authority to grant or deny market-based rates for sales of energy, capacity and ancillary services to ensure that such sales are just and reasonable.  FERC granted AGR market-based rate authority in December 2013.  FERC’s jurisdiction over ratemaking also includes the authority to suspend the market-based rates of utilities (including AGR, which is a public utility as defined by the FERC) and set cost-based rates if FERC subsequently determines that such utility can exercise market power, create barriers to entry or engage in abusive affiliate transactions.  Periodically, AGR is required to file a market power update to show that it continues to meet FERC’s standards with respect to generation market power and other criteria used to evaluate whether it continues to qualify for market-based rates.  Other matters subject to FERC jurisdiction include, but are not limited to, review of mergers, and dispositions of jurisdictional facilities and acquisitions of securities of another public utility or an existing operational generating facility.

Specific operations of AGR are also subject to the jurisdiction of various other Federal, state, regional and local agencies, including Federal and state environmental protection agencies.  AGR is also regulated by the PUCT for transactions inside ERCOT.  Additionally, AGR is subject to mandatory reliability standards promulgated by the North American Electric Reliability Corporation, with the approval of FERC. 

COMPETITION

OneThe AEP Generation & Marketing segment subsidiaries face competition for the sale of available power, capacity and ancillary services.  The principal factors of impact are electricity and fuel prices, new market entrants, construction or retirement of generating assets by others and technological advances in power generation. Because most of AGR’s remaining generation is coal-fired, lower relative natural gas prices will favor competitors that have a higher concentration of natural gas fueled generation.  Other factors impacting competitiveness include environmental regulation, transmission congestion or transportation constraints at or near generation facilities, inoperability or inefficiencies, outages and deactivations and retirements at generation facilities.

Technology advancements, increased demand for clean energy, changing consumer behaviors, low-priced and abundant natural gas, and regulatory and public policy reforms are among the catalysts for transformation within the industry that impact competition for AEP’s Generation & Marketing segment. AGR also competes with self-generation and with distributors of other energy sources, such as natural gas, fuel oil, renewables and coal, within their service areas.  The primary factors in such competition are price, unit availability and the capability of customers to utilize sources of energy other than electric power.

Changes in regulatory policies and advances in newer technologies for batteries or energy storage, fuel cells, microturbines, wind turbines and photovoltaic solar cells are reducing costs of new technology to levels that are making them competitive with some central station electricity production.  The ability to maintain relatively low cost, efficient and reliable operations and to provide cost-effective programs and services to customers are significant determinants of AGR’s competitiveness. The costs of photovoltaic solar cells in particular have continued to become increasingly competitive.

In the event that alternative generation resources are mandated, subsidized or encouraged through climate legislation or regulation or otherwise are economically competitive and added to the available generation supply, such resources could displace a higher marginal cost fossil plant, which could reduce the price at which market participants sell their electricity. These events could cause AGR to retire generating capacity prior to the end of its estimated useful life.



Changes in the global economy have led to increased competition for many industrial customers in the United States, including those served by the Generation & Marketing segment. Industrial customers that are downsizing or reorganizing often close a facility based upon its costs, which may include, among other things, the cost of electric power.  The Generation & Marketing segment works with such customers to meet their business needs through, for example, providing various off-peak or interruptible supply options. The Generation & Marketing segment also works with customers that seek to source more of their electric power from renewable resources.

SEASONALITY

The sale of electric power is generally a seasonal business.  In many parts of the most significant provisionscountry, demand for power peaks during the hot summer months, with market prices also peaking at that time.  In other areas, power demand peaks during the winter months.  The pattern of FERC Order No. 1000 isthis fluctuation may change.

Fuel Supply

The following table shows the removalgeneration sources by type, on an actual net generation (MWhs) basis, used by the Generation & Marketing segment, not including AGR’s ownership of the federal rightOklaunion generating unit:

Natural Gas36% 32%
Renewables2% 2%
A price increase/decrease in one or more fuel sources relative to other fuels, as well as the addition of first refusal for incumbent utilities within tariffs and agreements for certain regional transmission projects. Historically, vertically integrated public utilities hadrenewable resources, may result in the right to build and own transmission lines proposed by the region’s planning processes when those lines connected to facilities within their respective retail service territories.  FERC Order No. 1000 eliminates the federal rightdecreased/increased use of first refusal in regional transmission organization (RTO) tariffs for incumbent utilities to construct certain regional transmission projects within their own service territories, thereby creating the opportunity for any qualified entity to build and own regional transmission facilities in any service territory.  Transource was created to respond to FERC Order No. 1000 competitive processes at the RTO level.

AEP RIVER OPERATIONSother fuels.

Our AEP River Operations segment transports liquid,Coal and Consumables
AGR procures coal and dry bulk commodities primarily onconsumables needed to burn the Ohio, Illinoiscoal under a combination of purchasing arrangements including long-term and lower Mississippi rivers.  Almost allspot contracts with various producers and coal trading firms.  As contracts expire, they are replaced, as needed, with contracts at market prices. Coal and consumable inventories remain adequate to meet generation requirements.
Management believes that AGR will be able to secure and transport coal and consumables of our customers are nonaffiliatedadequate quality and in adequate quantities to operate their coal fired units.  AGR, through its contracts with third parties who obtainparty transporters, has the transportability to adequately move and store coal and consumables for use in its generating facilities. AGR plants consumed 10.4 million tons of coal in 2016.

The coal supplies at AGR plants vary from time to time depending on various factors, including, but not limited to, demand for electric power, unit outages, transportation infrastructure limitations, space limitations, plant coal consumption rates, coal quality, availability of acceptable coals, labor issues and dry bulk commoditiesweather conditions, which may interrupt production or deliveries. AGR aims to maintain the coal inventory of its managed plants in the range of 15 to 40 days of full load burn.  As of December 31, 2016, the coal inventory of AGR was above target.

Natural Gas

Despite the availability of natural gas due to the increased shale supply, the U.S. pipeline infrastructure remains a limiting factor in the expansion of natural gas-fired generation.  A portfolio of term, monthly, seasonal firm and daily peaking purchase and transportation agreements (that are entered into on a competitive basis and based on market prices) supplies natural gas requirements for various uses.  We chargeeach plant, as appropriate. AGR plants consumed 100 billion cubic feet of natural gas in 2016, an increase of approximately 8.7% from 2015.


Counterparty Risk Management

Counterparties and exchanges may require cash or cash related instruments to be deposited on these customers market ratestransactions as margin against open positions.  As of December 31, 2016, counterparties posted approximately $19 million in cash, cash equivalents or letters of credit with AEP for the purposebenefit of making a profit.  DependingAEP’s Generation & Marketing segment subsidiaries (while, as of that date, AEP’s Generation & Marketing segment subsidiaries posted approximately$142 million with counterparties and exchanges).  Since open trading contracts are valued based on market conditionsprices of various commodities, exposures change daily.  See Management’s Discussion and other factors, including barge availability, we permitAnalysis of Financial Condition and Results of Operations, included in the 2016 Annual Reports, under the heading entitled Quantitative and Qualitative Disclosures About Market Risk for additional information.

Certain Power Agreements

As of December 31, 2016, the assets utilized in this segment included approximately 310 MWs of company-owned domestic wind power facilities, 177 MWs of domestic wind power from long-term purchase power agreements and 355 MWs of coal-fired capacity which was obtained through an agreement effective through 2027 that transfers the interest of AEP utility subsidiary affiliatesTexas in the Oklaunion power station to use certain of our equipment at rates that reflect our cost.  Our affiliated utility customers procure the transport of coal for use as fuel in their respective generation plants.  AEP River Operations includes approximately 2,300 barges, 37 towboats and 18 harbor boats that we own or lease. In 2015, River Operations will operate its current fleet of 40 ten thousand barrel tank barges and may add an additional 40 ten thousand barrel tank barges throughout the year.  These assets are separateEnergy Partners, Inc.  The power obtained from the bargesOklaunion Power Station is marketed and towboats dedicated exclusively to transporting coal for use as fuelsold in our own generating facilities discussed under the prior segment.  See Item 1 – Vertically Integrated Utilities – Electric Generation – Fuel Supply – Coal and Lignite.ERCOT.



Competition within the barging industry for major commodity contracts is intense, with a number of companies offering transportation services in the waterways we serve.  We compete with other carriers primarily on the basis of commodity shipping rates, but also with respect to customer service, available routes, value-added services (including scheduling convenience and flexibility).  The industry continues to experience consolidation.  The resulting companies increasingly offer the widespread geographic reach necessary to support major national customers.  Demand for barging services can be seasonal, particularly with respect to the movement of harvested agricultural commodities (beginning in the late summer and extending through the fall).  Cold winter weather, water levels and inefficient older river locks may also limit our operations when certain of the waterways we serve are closed or commercial traffic is limited.

Our transportation operations are subject to regulation by the U.S. Coast Guard, federal laws, state laws and certain international conventions.  Legislation has been proposed that could make our towboats subject to inspection by the U.S. Coast Guard.

ITEM 1A.   RISK FACTORS

In addition to other disclosures within this report, including Management’s Discussion and Analysis of Financial Condition and Results of Operations, and other documents filed with the SEC from time to time, the following factors should be considered in evaluating the Registrants. Such factors could affect actual results of operations and cause results to differ substantially from those currently expected or sought. As indicated below, many of the following risk factors apply to AEP and several or all of the Registrant Subsidiaries and, accordingly, such risk factors should be read to include the applicable Registrants.

GENERAL RISKS OF OUR REGULATED OPERATIONS AND STATE RESTRUCTURING

WeAEP may not be able to recover the costs of our substantial planned investment in capital improvements and additions. Affecting each Registrant(Applies to all Registrants)

OurAEP’s business plan calls for extensive investment in capital improvements and additions, including the installation of environmental upgrades and retrofits, construction of additional transmission facilities, modernizing existing infrastructure as well as other initiatives.  OurAEP’s public utility subsidiaries currently provide service at rates approved by one or more regulatory commissions.  If these regulatory commissions do not approve adjustments to the rates we charge, wecharged, affected AEP subsidiaries would not be able to recover the costs associated with ourtheir planned extensive investment.  This would cause our financial results to be diminished.

Our regulatedRegulated electric revenues, earnings and results are dependent on federal and state regulation that may limit ourAEP’s ability to recover costs and other amounts. Affecting each Registrant(Applies to all Registrants)

The rates our customers pay to ourAEP regulated utility businesses are subject to approval by the FERC and the respective state utility commissions of Arkansas, Indiana, Kentucky, Louisiana, Michigan, Ohio, Oklahoma, Tennessee, Texas, Virginia and West Virginia, Oklahoma, Indiana, Louisiana, Kentucky, Arkansas, Michigan and Tennessee. Virginia. In certain instances, AEP’s applicable regulated utility businesses may agree to negotiated settlements related to various rate matters that are subject to regulatory approval. AEP cannot predict the ultimate outcomes of any settlements or the actions by the FERC or the respective state commissions in establishing rates.

If our regulated utility earnings exceed the returns established by the relevant commissions, retail electric rates may be subject to review and possible reduction by the commissions, which may decrease our future earnings. Additionally, if regulatory bodies do not allow recovery of costs incurred in providing service on a timely basis, it could reduce future net income and cash flows and negatively impact financial condition. Similarly, if recovery or other rate relief authorized in the past is overturned or reversed on appeal, our future earnings could be negatively impacted. Any regulatory action or litigation outcome that triggers a reversal of a regulatory asset or deferred cost, including fuel and related costs, generally results in an impairment to the balance sheet and a charge to the income statement of the company involved. See Note 4 of the Notes to Consolidated Financial Statements entitled Rate Matters for information regarding rate proceedings.

OurAEP’s transmission investment strategy and execution bears certain risks associated with these activities. Affecting each Registrant(Applies to all Registrants)

We expectManagement expects that a growing portion of ourAEP’s earnings in the future will derivebe derived from the transmission investments and activities of AEPTCo and our transmission joint ventures.activities.  FERC policy currently favors the expansion and updating of the transmission infrastructure within its jurisdiction.  If FERC were to adopt a different policy, if states were to limit or restrict such policies, or if transmission needs do not continue or develop as projected, ourAEP’s strategy of investing in transmission could be curtailed.  We believe ourimpacted.  Management believes AEP’s experience with transmission facilities construction and operation gives usAEP an advantage over other competitors in securing authorization to install, construct and operate new transmission lines and facilities.  However, there can be no assurance that PJM, SPP or other RTOs will authorize any new transmission projects or will award any such projects to us.  AEP.  


In October 2016, several parties filed a joint complaint with the FERC claiming that the base return on common equity used by various AEP affiliates in calculating formula transmission rates under the PJM Open Access Transmission Tariff (OATT) is excessive and should be reduced from 10.99% to 8.32%, effective upon the date of the complaint. If the FERC orders revenue reductions as a result of the complaint, including refunds from the date of the complaint filing, it could reduce future net income and cash flows and impact financial condition.

If the FERC were to lower the rate of return it has authorized for ourAEP’s transmission investments and facilities, or if one or more states were to successfully limit FERC jurisdiction on recovery of costs on transmission investment and its return, it could reduce future net income and cash flows and negatively impact financial condition.


Changes in technology and regulatory policies may lower the value of electric utility facilities and franchises. (Applies to all Registrants)
34
AEP primarily generates electricity at large central facilities and delivers that electricity to customers over its transmission and distribution facilities to customers usually situated within an exclusive franchise. This method results in economies of scale and generally lower costs than newer technologies such as fuel cells and microturbines, and distributed generation using either new or existing technology.  Other technologies, such as light emitting diodes (LEDs), increase the efficiency of electricity and, as a result, lower the demand for it.   Changes in regulatory policies and advances in batteries or energy storage, wind turbines and photovoltaic solar cells are reducing costs of new technology to levels that are making them competitive with some central station electricity production and delivery.  The ability to maintain relatively low cost, efficient and reliable operations, to establish fair regulatory mechanisms and to provide cost-effective programs and services to customers are significant determinants of AEP’s competitiveness.   Further, in the event that alternative generation resources are mandated, subsidized or encouraged through climate legislation or regulation or otherwise are economically competitive and added to the available generation supply, such resources could displace a higher marginal cost fossil plant, which could reduce the price at which market participants sell their electricity. This occurrence could then reduce the market price at which all generators in that region would be able to sell their output and could adversely affect AEP’s financial condition, results of operations and cash flows, which could also result in an impairment of certain long-lived assets.



WeAEP may not recover costs incurred to begin construction on projects that are canceled. Affecting each Registrant(Applies to all Registrants)

OurAEP’s business plan for the construction of new projects involves a number of risks, including construction delays, nonperformance by equipment and other third party suppliers, and increases in equipment and labor costs.  To limit the risks of these construction projects, weAEP and its subsidiaries enter into equipment purchase orders and construction contracts and incur engineering and design service costs in advance of receiving necessary regulatory approvals and/or siting or environmental permits.  If any of these projects isare canceled for any reason, including our failure to receive necessary regulatory approvals and/or siting or environmental permits, we could incur significant cancellation penalties under the equipment purchase orders and construction contracts.contracts could occur.  In addition, if we have recorded any construction work or investments have been recorded as an asset, wean impairment may need to impair that assetbe recorded in the event the project is canceled.

We are

AEP is exposed to nuclear generation risk. Affecting(Applies to AEP and I&M&M)

Through I&M, we ownAEP owns the Cook Plant.  It consists of two nuclear generating units for a rated capacity of 2,191 MW,MWs, or about 6%7% of the generating capacity in the AEP System.  WeAEP and I&M are, therefore, subject to the risks of nuclear generation, which include the following:

The potential harmful effects on the environment and human health due to an adverse incident/event resulting from the operation of nuclear facilities and the storage, handling and disposal of radioactive materials such as spent nuclear fuel.
Limitations on the amounts and types of insurance commercially available to cover losses that might arise in connection with our nuclear operations.
Uncertainties with respect to contingencies and assessment amounts triggered by a loss event (federal law requires owners of nuclear units to purchase the maximum available amount of nuclear liability insurance and potentially contribute to the coverage for losses of others).
Uncertainties with respect to the technological and financial aspects of decommissioning nuclear plants at the end of their licensed lives.

There can be no assurance that I&M’s preparations or risk mitigation measures will be adequate if and when these risks are triggered.

The NRC has broad authority under federal law to impose licensing and safety-related requirements for the operation of nuclear generation facilities.  In the event of non-compliance, the NRC has the authority to impose fines or shut down a unit, or both, depending upon its assessment of the severity of the situation, until compliance is achieved.  Revised safety requirements promulgated by the NRC could necessitate substantial capital expenditures at nuclear plants such as ours.plants.  In addition, although we havemanagement has no reason to anticipate a serious nuclear incident at our plants,the Cook Plant, if an incident did occur, it could harm our results of operations or financial condition.  A major incident at a nuclear facility anywhere in the world could cause the NRC to limit or prohibit the operation or licensing of any domestic nuclear unit.  Moreover, a major incident at any nuclear facility in the U.S. could require usAEP or I&M to make material contributory payments.

Costs associated with the operation (including fuel), maintenance and retirement of nuclear plants continue to be more significant and less predictable than costs associated with other sources of generation, in large part due to changing regulatory requirements and safety standards, availability of nuclear waste disposal facilities and experience gained in the operation of nuclear facilities.  Costs also may include replacement power, any unamortized investment at the end of the useful life of the Cook Plant (whether scheduled or premature), the carrying costs of that investment and retirement costs.  OurThe ability to obtain adequate and timely recovery of costs associated with the Cook Plant is not assured.


35



The different regional power markets in which weAEP subsidiaries compete or will compete in the future have changing market and transmission structures, which could affect our performance in these regions. Affecting each Registrant(Applies to all Registrants)

Our resultsResults are likely to be affected by differences in the market and transmission structures in various regional power markets.  The rules governing the various regional power markets, including SPP and PJM, may also change from time to time which could affect our costs or revenues.  Because the manner in which RTOs will evolve remains unclear, we aremanagement is unable to assess fully the impact that changes in these power markets may have on ourthe business.

WeAEP could be subject to higher costs and/or penalties related to mandatory reliability standards. Affecting each Registrant(Applies to all Registrants)

As a result of EPACT, owners and operators of the bulk power transmission system are subject to mandatory reliability standards promulgated by the North American Electric Reliability Corporation and enforced by the FERC.  The standards are based on the functions that need to be performed to ensure the bulk power system operates reliably and are guided by reliability and market interface principles.  Compliance with new reliability standards may subject us AEP


to higher operating costs and/or increased capital expenditures.  While we expectmanagement expects to recover costs and expenditures from customers through regulated rates, there can be no assurance that the applicable commissions will approve full recovery in a timely manner.  If weAEP were found not to be in compliance with the mandatory reliability standards, weAEP could be subject to sanctions, including substantial monetary penalties, which likely would not be recoverable from customers through regulated rates.

AEP may be negatively impacted by changes in federal income tax policy.  (Applies to all Registrants)

AEP is impacted by the United States federal income tax policy, including corporate income tax laws. Both the new federal administration and the Republicans in the House of Representatives have made public statements in support of comprehensive tax reform, including significant changes to the United States corporate income tax laws. Management is currently unable to predict whether these reform discussions will result in any significant changes to existing tax laws, or if any such changes would have a cumulative positive or negative impact on AEP. A reduction in the federal statutory tax rate could result in an accelerated return of deferred federal income taxes to customers.  This and other changes in the United States federal income tax laws could have an adverse effect on cash flow, financial condition, and liquidity.

Collection of revenues in Texas is concentrated in a limited number of REPs. (Applies to AEP)

Revenues from the distribution of electricity in the ERCOT area of Texas are collected from REPs that supply the electricity AEP distributes to REP customers.  Currently, AEP does business with approximately one hundred REPs.  In 2016, AEP Texas’ largest REP accounted for 18% of its operating revenue, its second largest REP accounted for 18% of its operating revenue and its third largest REP accounted for 10% of its operating revenue. Adverse economic conditions, structural problems in the Texas market or financial difficulties of one or more REPs could impair the ability of these REPs to pay for services or cause them to delay such payments.  AEP depends on these REPs for timely remittance of payments.  Any delay or default in payment could reduce future cash flows and negatively impact financial condition.

RISKS RELATED TO MARKET, ECONOMIC OR FINANCIAL VOLATILITY AND OTHER RISKS

OurAEP’s financial performance may be adversely affected if we areAEP is unable to successfully operate our facilities or perform certain corporate functions. Affecting each Registrant(Applies to all Registrants)

Our performancePerformance is highly dependent on the successful operation of our generation, transmission and distribution facilities.  Operating these facilities involves many risks, including:

Operator error and breakdown or failure of equipment or processes.
Operating limitations that may be imposed by environmental or other regulatory requirements.
Labor disputes.
Compliance with mandatory reliability standards, including mandatory cyber security standards.
Information technology failure that impairs ourAEP’s information technology infrastructure or disrupts normal business operations.
Information technology failure that affects ourAEP’s ability to access customer information or causes us to loseloss of confidential or proprietary data that materially and adversely affects ourAEP’s reputation or exposes usAEP to legal claims.
Fuel or water supply interruptions caused by transportation constraints, adverse weather such as drought, non-performance by our suppliers and other factors.
Catastrophic events such as fires, earthquakes, explosions, hurricanes, tornados, ice storms, terrorism (including cyber-terrorism), floods or other similar occurrences.
Fuel costs and related requirements triggered by financial stress in the coal industry.



HostilePhysical attacks or hostile cyber intrusions could severely impair our operations, lead to the disclosure of confidential information and damage ourAEP’s reputation. Affecting each Registrant(Applies to all Registrants)

WeAEP and its regulated utility businesses face physical security and cybersecurity risks as the owner-operators of generation, transmission and distribution facilities and as participants in commodities trading. AEP and its regulated utility businesses own assets deemed as critical infrastructure, the operation of which is dependent on information technology systems. Further, the computer systems that run ourthese facilities are not completely isolated from external networks. Parties that wish to disrupt the U.S. bulk power system or ourAEP operations could view ourthese computer systems, software or networks as targets for cyber attack.  In addition, ourthe electric utility business requires that we collect and maintainthe collection of sensitive customer data, as well as confidential employee and shareholder information, which is subject to electronic theft or loss.


36



A security breach of AEP or its regulated utility businesses’ physical assets or information systems, AEP’s competitors, interconnected entities in RTOs and ISOs, or regulators could impact the operation of the generation fleet and/or reliability of the transmission and distribution system or subject AEP and its regulated utility businesses to financial harm associated with theft or inappropriate release of certain types of information, including sensitive customer, vendor, employee, trading or other confidential data. A successful cyber attack on the systems that control our generation, transmission, distribution or other assets could severely disrupt business operations, preventing us from servingservice to customers or collectingcollection of revenues. The breach of certain business systems could affect ourthe ability to correctly record, process and report financial information. A major cyber incident could result in significant expenses to investigate and repair security breaches or system damage and could lead to litigation, fines, other remedial action, heightened regulatory scrutiny and damage to ourAEP’s reputation. In addition, the misappropriation, corruption or loss of personally identifiable information and other confidential data could lead to significant breach notification expenses and mitigation expenses such as credit monitoring.  We maintain cyber insurance to cover liabilities and losses directly arising from a potential cyber event.  We also maintain property and casualty insurance that may cover certain resultant physical damage or third-party injuries caused by potential cyber events.  However, damage and claims arising from such incidents may exceed the amount of any insurance available and other damage and claims arising from such incidents may not be covered at all. For these reasons, a significant cyber incident could reduce future net income and cash flows and negatively impact financial condition.

In an effort to reduce the likelihood and severity of cyber intrusions, we haveAEP has a comprehensive cyber security program designed to protect and preserve the confidentiality, integrity and availability of data and systems. In addition, we areAEP is subject to mandatory cyber security regulatory requirements. However, cyber threats continue to evolve and adapt, and, as a result, there is a risk that weAEP could experience a successful cyber attack despite our current security posture and regulatory compliance efforts.

If we areAEP is unable to access capital markets on reasonable terms, it could reduce future net income and cash flows and negatively impact financial condition. Affecting each Registrant(Applies to all Registrants)

We relyAEP relies on access to capital markets as a significant source of liquidity for capital requirements not satisfied by operating cash flows.  Volatility and reduced liquidity in the financial markets could affect ourAEP’s ability to raise capital and fund our capital needs, including construction costs and refinancing maturing indebtedness.  In addition, ifCertain sources of debt and equity capital is available onlyexpressed increasing unwillingness to invest in companies, such as AEP, that rely on less than reasonable terms or to borrowers whose creditworthiness is better than ours,fossil fuels. If sources of capital for AEP disappear, capital costs could increase materially.  Restricted access to capital markets and/or increased borrowing costs could reduce future net income and cash flows and negatively impact financial condition.

Downgrades in ourAEP’s credit ratings could negatively affect ourits ability to access capital and/or to operate ourthe power trading businesses. Affecting each Registrant(Applies to all Registrants)

The credit ratings agencies periodically review ourAEP’s capital structure and the quality and stability of our earnings.  Any negative ratings actions could constrain the capital available to usAEP and could limit our access to funding for our operations.  OurAEP’s business is capital intensive, and we areAEP is dependent upon ourthe ability to access capital at rates and on terms we determinemanagement determines to be attractive.  In periods of market turmoil, access to capital is difficult for all borrowers.  If ourAEP’s ability to access capital becomes significantly constrained, ourAEP’s interest costs will likely increase and could reduce future net income and cash flows and negatively impact financial condition.

Our

AEP’s power trading business relies on the investment grade ratings of ourAEP’s individual public utility subsidiaries’ senior unsecured long-term debt or on the investment grade ratings of AEP.  Most of our counterparties require the creditworthiness of an investment grade entity to stand behind transactions.  If those ratings were to decline below investment grade, ourAEP’s ability to operate ourthe power trading business profitably would be diminished because weAEP would likely have to deposit cash or cash-related instruments which would reduce future net income and cash flows and negatively impact financial condition.

AEP has no income or cash flow apart from dividends paid or other obligationspayments due it from its subsidiaries. Affecting AEP(Applies to AEP)

AEP is a holding company and has no operations of its own.  Its ability to meet its financial obligations associated with its indebtedness and to pay dividends on its common stock is primarily dependent on the earnings and cash flows of its operating subsidiaries, primarily its regulated utilities, and the ability of its subsidiaries to pay dividends to, or repay loans from, AEP.  Its subsidiaries are separate and distinct legal entities that have no obligation (apart from loans

37



from AEP) to provide AEP with funds for its payment obligations, whether by dividends, distributions or other payments.  Payments to AEP by its subsidiaries are also contingent upon their earnings and business considerations.  AEP indebtedness and common stock dividends are structurally subordinated to all subsidiary indebtedness.

OurAEP’s operating results may fluctuate on a seasonal or quarterly basis and with general economic and weather conditions. Affecting each Registrant(Applies to all Registrants)

Electric power generation is generally a seasonal business.  In many parts of the country, demand for power peaks during the hot summer months, with market prices also peaking at that time.  In other areas, power demand peaks during the winter.  As a result, our overall operating results in the future may fluctuate substantially on a seasonal basis.  The pattern of this fluctuation may change depending on the terms of power sale contracts that we enterAEP enters into.  In addition, we haveAEP has historically sold less power, and consequently earned less income, when weather conditions are milder.  Unusually mild weather in the future could reduce future net income and cash flows and negatively impact financial condition.  Conversely,In addition, unusually extreme weather conditions could increaseimpact AEP’s results of operations in a manner that would not likely be sustainable.

Further, deteriorating economic conditions generally result in reduced consumption by our customers, particularly industrial customers who may curtail operations or cease production entirely, while an expanding economic environment generally results in increased revenues.  As a result, prevailing economic conditions may reduce our future net income and cash flows and negatively impact financial condition.

Volatility in the securities markets, interest rates, and other factors could substantially increase defined benefit pension and other postretirement plan costs and the costs of nuclear decommissioning. (Applies to all Registrants and to AEP and I&M with respect to the costs of nuclear decommissioning)

The costs of providing pension and other postretirement benefit plans are dependent on a number of factors, such as the rates of return on plan assets, discount rates, the level of interest rates used to measure the required minimum funding levels of the plan, changes in actuarial assumptions, future government regulation, changes in life expectancy, and the frequency and amount of AEP’s required or voluntary contributions made to the plans. Changes in actuarial assumptions and differences between the assumptions and actual values, as well as a significant decline in the value of investments that fund the pension and other postretirement plans, if not offset or mitigated by a decline in plan liabilities, could increase pension and other postretirement expense, and AEP could be required from time to time to fund the pension plan with significant amounts of cash. Such cash funding obligations could have a material impact on liquidity by reducing cash flows and could negatively affect results of operations. Additionally, I&M holds a significant amount of assets in its nuclear decommissioning trusts to satisfy obligations to decommission its nuclear plant. The rate of return on assets held in those trusts can significantly impact both the costs of decommissioning and the funding requirements for the trusts.



Failure to attract and retain an appropriately qualified workforce could harm our results of operations. Affecting each Registrant(Applies to all Registrants)

Certain events, such as an aging workforce without appropriate replacements, mismatch of skillset or complement to future needs, or unavailability of contract resources may lead to operating challenges and increased costs.  The challenges include lack of resources, loss of knowledge and a lengthy time period associated with skill development.  In this case, costs, including costs for contractors to replace employees, productivity costs and safety costs, may rise.  Failure to hire and adequately train replacement employees, including the transfer of significant internal historical knowledge and expertise to the new employees, or the future availability and cost of contract labor may adversely affect the ability to manage and operate ourthe business.  If we areAEP is unable to successfully attract and retain an appropriately qualified workforce, our future net income and cash flows may be reduced.

Changes in commodity pricesthe price of commodities, emission allowances for criteria pollutants and the costs of transport may increase ourAEP’s cost of producing power or decrease the amount we receivereceived from selling power, harming ourimpacting financial performance. Affecting each Registrant(Applies to all Registrants)

We areAEP is exposed to changes in the price and availability of coal and the price and availability to transport coal.  We haveAEP has existing contracts of varying durations for the supply of coal, but as these contracts end or otherwiseif they are not honored, weAEP may not be able to purchase coal on terms as favorable as the current contracts.  Similarly, we areAEP is exposed to changes in the price and availability of emission allowances.  We useAEP uses emission allowances based on the amount of coal we useused as fuel and the reductions achieved through emission controls and other measures.  As long as current environmental programs remain in effect, we haveAEP has sufficient emission allowances to cover the majority of ourthe projected needs for the next two years and beyond.  If the Federal EPA is ableattempts to create a replacement rule tofurther reduce interstate transport, and it is acceptable by the courts, additional costs may be incurred either to acquire additional allowances or to achieve further reductions in emissions.  If we needAEP needs to obtain allowances, under a replacement rule, those purchases may not be on as favorable terms as those under the current environmental programs.  OurAEP’s risks relative to the price and availability to transport coal include the volatility of the price of diesel which is the primary fuel used in transporting coal by barge.


38



WeAEP also ownowns natural gas-fired facilities which exposes usAEP to market prices of natural gas.  Historically, natural gas prices have tended to be more volatile than prices for other fuel sources. Recently however, the availability of natural gas from shale production has lessened price volatility. OurAEP’s ability to make sales at a profit is highly dependent on the price of natural gas.  As the price of natural gas falls, other market participants that utilize natural gas-fired generation will be able to offer electricity at increasingly competitive prices relative to ourAEP’s sales prices, so the margins we realizerealized from sales will be lower and, on occasion, weAEP may need to curtail operation of marginal plants.  We expectManagement expects the availability of shale natural gas and issues related to its accessibility will have a long-term material effect on the price and volatility of natural gas.

Prices for coal, natural gas and emission allowances have shown material upward and downward swings in the past.  Changes in the cost of coal, emission allowances or natural gas and changes in the relationship between such costs and the market prices of power could reduce future net income and cash flows and negatively impact financial condition.

In addition, actual power prices and fuel costs will differ from those assumed in financial projections used to value our trading and marketing transactions, and those differences may be material.  As a result, as those transactions are marked to market, those transactionsthey may reduceimpact future results of operations and cash flows and impact financial condition.

Our AEP River Operations segment is subject to risks that are beyond our control. Affecting AEP

Our AEP River Operations segment transports liquid, coal and dry bulk commodities primarily on the Ohio, Illinois and lower Mississippi rivers.  These activities can be hazardous and depend on natural conditions and forces.  Our river transport operations could result in an environmental event such as a serious spill or release.  In addition, if drought conditions or other factors cause the water levels of one or more of these rivers to drop below the amount necessary to permit commercial barging traffic, it would prevent our AEP River Operations from transporting cargo on the affected river.  Conversely, if unusually high amounts of precipitation or other factors cause the water levels of one or more of these rivers to be too high to permit commercial barging traffic, it would prevent our AEP River Operations from transporting cargo on the affected river.  Extreme water levels that do not close river basin commercial traffic can still harm our business if the levels curtail the total volume permitted to move on the affected river. The levels on portions of the Mississippi River in 2013 were near the lowest since the levels caused by severe drought in 1988.  Water levels during 2014 were improved and generally considered favorable for barge operations. Any reduction in the commercial activities of our AEP River Operations due to extreme water levels could reduce future net income and cash flows.

We are subject to physical and financial risks associated with climate change. Affecting each Registrant(Applies to all Registrants)

Climate change creates physical and financial risk.  Physical risks from climate change may include an increase in sea level and changes in weather conditions, such as changes in precipitation and extreme weather events.  Our customers’Customers’ energy needs vary with weather conditions, primarily temperature and humidity.  For residential customers, heating and cooling represent their largest energy use.  To the extent weather conditions are affected by climate change, customers’ energy use could increase or decrease depending on the duration and magnitude of the changes.


Increased energy use due to weather changes may require usAEP to invest in additional generating assets, transmission and other infrastructure to serve increased load.  Decreased energy use due to weather changes may affect our financial condition through decreased revenues.  Extreme weather conditions in general require more system backup, adding to costs, and can contribute to increased system stress, including service interruptions.  Weather conditions outside of ourthe AEP service territory could also have an impact on our revenues.  We buyAEP buys and sellsells electricity depending upon system needs and market opportunities.  Extreme weather conditions creating high energy demand on ourAEP’s own and/or other systems may raise electricity prices as we buyAEP buys short-term energy to serve ourAEP’s own system, which would increase the cost of energy we provideAEP provides to our customers.


39



Severe weather impacts ourAEP’s service territories, primarily when thunderstorms, tornadoes, hurricanes, floods and snow or ice storms occur.  To the extent the frequency of extreme weather events increases, this could increase ourAEP’s cost of providing service.  Changes in precipitation resulting in droughts, or water shortages or floods could adversely affect our operations, principally ourthe fossil fuel generating units.  A negative impact to water supplies due to long-term drought conditions or severe flooding could adversely impact ourAEP’s ability to provide electricity to customers, as well as increase the price they pay for energy.  WeAEP may not recover all costs related to mitigating these physical and financial risks.

To the extent climate change impacts a region’s economic health, it may also impact our revenues.  OurAEP’s financial performance is tied to the health of the regional economies we serve.AEP serves.  The price of energy, as a factor in a region’s cost of living as well as an important input into the cost of goods and services, has an impact on the economic health of our communities.the communities within the AEP System.

WeManagement cannot predict the outcome of the legal proceedings relating to ourAEP’s business activities. Affecting each Registrant(Applies to all Registrants)

We areAEP is involved in legal proceedings, claims and litigation arising out of ourits business operations, the most significant of which are summarized in Note 6 of the Notes to Consolidated Financial Statements entitled Commitments, Guarantees and Contingencies.  Adverse outcomes in these proceedings could require significant expenditures that could reduce future net income and cash flows and impact financial condition.

RISKS RELATING TO STATE RESTRUCTURING

Customers are choosing alternative electric generation service providers, as allowed by Ohio law and regulation. Affecting AEP

Under current Ohio law, electric generation is sold in a competitive market in Ohio and native load customers in Ohio have the ability to switch to alternative suppliers for their electric generation service.  CRES providers are targeting retail customers by offering alternative generation service.   As customer switching in Ohio continues, it could reduce AGR’s future net income and cash flows and impact financial condition.

Collection of our revenues in Texas is concentrated in a limited number of REPs. Affecting AEP

Our revenues from the distribution of electricity in the ERCOT area of Texas are collected from REPs that supply the electricity we distribute to their customers.  Currently, we do business with approximately one hundred REPs.  In 2014, TCC’s largest REP accounted for 25% of its operating revenue and its second largest REP accounted for 23% of its operating revenue; TNC’s largest REP accounted for 11% of its operating revenues, and its second largest REP accounted for 9% of its operating revenues.  Adverse economic conditions, structural problems in the Texas market or financial difficulties of one or more REPs could impair the ability of these REPs to pay for our services or cause them to delay such payments.  We depend on these REPs for timely remittance of payments.  Any delay or default in payment could reduce future cash flows andnegatively impact financial condition.

RISKS RELATED TO OWNING AND OPERATING GENERATION ASSETS AND SELLING POWER

Our costsCosts of compliance with existing environmental laws are significant. Affecting each Registrant(Applies to all Registrants)

Our operationsOperations are subject to extensive federal, state and local environmental statutes, rules and regulations relating to air quality, water quality, waste management, natural resources and health and safety.  Approximately 90%82% of the electricity generated by the AEP System is produced by the combustion of fossil fuels.  Emissions of nitrogen and sulfur oxides, mercury and particulates from fossil fueled generation plants are subject to increased regulations, controls and mitigation expenses.  Compliance with these legal requirements requires usAEP to commit significant capital toward environmental monitoring, installation of pollution control equipment, emission fees and permits at all of ourAEP facilities and could cause usAEP to retire generating capacity prior to the end of its estimated useful life.  These expenditures have been significant in the past, and we expectmanagement expects that they will continue to be significant in order to comply with the current and proposed regulations.  Costs of compliance with environmental regulations could reduce future net income and

40



negatively impact financial condition, especially if emission and/or discharge limits are tightened, more extensive permitting requirements are imposed or additional substances become regulated.  If we retire generation plants prior to the end of their estimated useful life, there can be no assurance that we will recover the remaining costs associated with such plants.  WeAlthough AEP typically recover ourrecovers expenditures for pollution control technologies, replacement generation, undepreciated plant balances and associated operating costs from customers through regulated rates in regulated jurisdictions.jurisdictions, there can be no assurance that AEP will recover the remaining costs associated with such plants.  Failure to recover these costs could reduce our future net income and cash flows and possibly harm our financial condition.  For ourAEP’s sales of energy from our competitive units, there is no such cost-recovery mechanism.   As a result, weAEP may not recover our costs through the market and we may be forced to shut competitive units down.  The costs of compliance for ourAEP’s competitive units could reduce our future net income and cash flows and possibly harm our financial condition.



Regulation of CO2 emissions could materially increase costs to usAEP and ourits customers or cause some of our electric generating units to be uneconomical to operate or maintain. Affecting each Registrant(Applies to all Registrants)

The U.S. Congress has not taken any significant steps toward enacting legislation to control CO2 emissions since 2009.  In December 2009, the Federal EPA issued a final endangerment finding under the CAA regarding emissions from motor vehicles.  The Federal EPA finalized CO2 emission standards for new motor vehicles and issued a rule that implements a permitting program for new and modified stationary sources of CO2 emissions in a phased manner.  Several groups have filed challenges to the endangerment finding and the Federal EPA’s subsequent rulemakings.  The Supreme Court agreed to review whether the Federal EPA reasonably determined that establishing standards for new motor vehicles automatically triggered regulation of stationary sources through the prevention of significant deterioration and Title V permitting programs, and determined that the Federal EPA was neither compelled nor authorized to automatically regulate stationary sources of CO2 emissions under these programs, but that the Federal EPA could establish requirements for best available control technology reviews of CO2 emissions for sources otherwise required to obtain a Prevention of Significant Deterioration permit if their emissions exceed a reasonable level.  The Federal EPA must undertake additional rulemaking to establish such requirements and a reasonable level.

In 2012, the Federal EPA issued a proposed CO2 emissions standard for new power generation sources.  In response to the comments submitted on this proposed rule, and in accordance with a directive from the President, the Federal EPA withdrew the April 2012 proposed rule and has issued a new proposal.  This proposed rule includes separate, but equivalent, standards for natural gas and coal-fired units, based on the use of partial carbon capture and storage at coal units.  In June 2014, the Federal EPA issued standards for new, modified and reconstructed units, and a guideline for the development
of state implementation plans that would reduce carbon emissions from existing utility units. The standards and guidelines were finalized in 2015, and have been challenged by several dozen states as well as industry groups and other stakeholders. The U.S. Supreme Court has stayed the implementation of the guidelines for existing sources, include aggressive emission rate goals that are composed ofknown as the Clean Power Plan, until a number of measures.  Management believes some policy approaches being discussed would have significant and widespread negative consequences forfinal decision is issued by the national economy and major U.S. industrial enterprises, including AEP and our customers.courts.

CO2 standards could require significant increases in capital expenditures and operating costs and could impact the dates for retirement of ourAEP’s coal-fired units. WeAEP typically recoverrecovers costs of complying with new requirements such as the potential CO2 and other greenhouse gases emission standards from customers through regulated rates in regulated jurisdictions. For ourAEP’s sales of energy into the markets, however, there is no such recovery mechanism. Failure to recover these costs, should they arise, could reduce our future net income and cash flows and possibly harm our financial condition.

We may be harmed if our merchant generation fleet is not profitable or loses value. Affecting AEP

We are evaluating strategic alternatives for our merchant generation fleet, which primarily includes AGR’s generation fleet which operates in PJM and a 54.7% interest in the Oklaunion Plant which operates in ERCOT.    Potential alternatives may include, but are not limited to, continued operation of the merchant generation fleet, executing a PPA with a regulated affiliate for certain merchant generation units in Ohio, a spin-off of the merchant generation fleet or a sale of the merchant generation fleet.  We have not made a decision regarding the potential alternatives, nor have we set a specific timeframe for a decision.  Certain of these alternatives could result in a loss which could reduce future net income and cash flow and impact financial condition.

Amounts we receive from the results of PJM capacity auctions associated with our nonregulated generation assets could fail to adequately compensate us. Affecting AEP

Financial returns on AGR’s generation capacity are subject to the results of annual PJM capacity auctions.  Recent auction results indicate a great deal of volatility and the possibility of clearing prices substantially lower than the cost of such capacity.   We expect a significant decline in AGR capacity revenues after May 2015 when the Power Supply Agreement between AGR and OPCo ends.  Additionally, we expect a decline in AGR capacity revenues from June 2016 through May 2017 based upon the decrease in the PJM base auction price.  PJM recently proposed at FERC a set of supplemental auctions for 2016/17 and 2017/18. Those auctions may mitigate the decline in capacity revenues.  However, this proposal has not yet been accepted at FERC and we can give no assurance that the FERC will approve the proposal.  If the PJM capacity auctions continue to result in clearing prices lower than the cost of our capacity, it could reduce our future net income and cash flows and impact financial condition.

Courts adjudicating nuisance and other similar claims in the future may order usAEP to pay damages or to limit or reduce our emissions. Affecting each Registrant(Applies to all Registrants)

In the past, there have been several cases seeking damages based on allegations of federal and state common law nuisance in which we,AEP, among others, were defendants.  In general, the actions allege that emissions from the defendants’ power plants constitute a public nuisance.  The plaintiffs in these actions generally seek recovery of damages and other relief.  If future actions are resolved against us,AEP, substantial modifications of ourAEP’s existing coal-fired power plants could be required and weAEP might be required to limit or reduce emissions.  Such remedies could require usAEP to purchase power from third parties to fulfill ourAEP’s commitments to supply power to ourAEP customers.  This could have a material impact on our costs.  In addition, weAEP could be required to invest significantly in additional emission control equipment, accelerate the timing of capital expenditures, pay damages or penalties and/or halt operations.  While management believes such costs should be recoverable from customers as costs of doing business in ourAEP jurisdictions where generation rates are set on a cost of service basis, without such recovery, those costs could reduce our future net income and cash flows and harm our financial condition.  Moreover, our results of operations and financial position could be reduced due to the timing of recovery of these investments and the expense of ongoing litigation.

Our profitabilityProfitability is impacted by ourAEP’s continued authorization to sell power at market-based rates. Affecting each Registrant(Applies to all Registrants)

FERC has granted AGR, APCo, I&M, KPCo, OPCo, PSO and SWEPCo authority to sell electricity at market-based rates. FERC reserves the right to revoke or revise this market-based rate authority if it subsequently determines that one or more of these companies can exercise market power in transmission or generation, create barriers to entry or engage in abusive affiliate transactions.  Each company that has obtained market-based rate authority from FERC must file a market power update every three years to show that they continue to meet FERC’s standards with respect to generation market power and other criteria used to evaluate whether entities qualify for market-based rates.  The loss of market-based rate authority by any of these entities, especially by AGR, could have a material adverse effect on our results of operations.

Our revenuesRevenues and results of operations from selling power are subject to market risks that are beyond ourAEP’s control. Affecting each Registrant(Applies to all Registrants)

We sellAEP sells power from ourits generation facilities into the spot market and other competitive power markets on a contractual basis.  WeAEP also enterenters into contracts to purchase and sell electricity, natural gas, emission allowances and coal as part of ourits power marketing and energy trading operations.  With respect to such transactions, the rate of return on our capital investments is not determined through mandated rates, and our revenues and results of operations are likely to depend, in large part, upon prevailing market prices for power in our regional markets and other competitive markets.  These market prices can fluctuate substantially over relatively short periods of time.  TradingSales margins may erode as markets mature and there may be diminished opportunities for gain should volatility decline.  In addition, the FERC, which has jurisdiction over wholesale power rates, as well as RTOs that oversee some of these markets, may impose price limitations, bidding rules and other mechanisms to address some of the volatility in these markets.  Power supply and other similar agreements entered into during extreme market conditions may subsequently be held to be unenforceable by a reviewing court or the FERC.  Fuel and emissions prices may also be volatile, and the price weAEP can obtain for power sales may not change at the same rate as changes in fuel and/or emissions costs.  These factors could reduce our margins and therefore diminish our revenues and results of operations.  Volatility in market prices for fuel and power may result from:

Weather conditions, including storms.
Economic conditions.
Outages of major generation or transmission facilities.
Seasonality.
Power usage.
Illiquid markets.
Transmission or transportation constraints or inefficiencies.
Availability of competitively priced alternative energy sources.
Demand for energy commodities.
Natural gas, crude oil and refined products and coal production levels.
Natural disasters, wars, embargoes and other catastrophic events.
Federal, state and foreign energy and environmental regulation and legislation and/or incentives.

Commodity trading and marketing activities are subject to inherent risks which can be reduced and controlled but not eliminated. Affecting each Registrant(Applies to all Registrants)

We attempt to manage theThe exposure of orAEP’s power trading activities is managed by establishing and enforcing risk limits and risk management procedures. These risk limits and risk management procedures may not work as planned and cannot eliminate the risks associated with these activities.  As a result, wemanagement cannot predict the impact that ourAEP’s energy trading and risk management decisions may have on ourAEP’s business, operating results or financial position.

WeAEP routinely havehas open trading positions in the market, within guidelines we set by AEP, resulting from the management of ourAEP’s trading portfolio.  To the extent open trading positions exist, fluctuating commodity prices can improve or diminish our financial results and financial position.


43




OurAEP’s power trading risk management activities, including our power sales agreements with counterparties, rely on projections that depend heavily on judgments and assumptions by management of factors such as the future market prices and demand for power and other energy-related commodities.  These factors become more difficult to predict and the calculations become less reliable the further into the future these estimates are made.  Even when our policies and procedures are followed and decisions are made based on these estimates, results of operations may be diminishedimpacted if the judgments and assumptions underlying those calculations prove to be inaccurate.

We may not successfully manage the uncertainty involved with our power trading (including coal, natural gas and emission allowances trading and power marketing). Affecting each Registrant

OurAEP’s power trading activities also expose usAEP to risks of commodity price movements.  To the extent that ourAEP’s power trading does not hedge the price risk associated with the generation it owns, or controls, through long-term power purchase agreements, weAEP would be exposed to the risk of rising and falling spot market prices.

For example, the use of new technologies to recover natural gas from shale deposits has increased natural gas supply and reserves, placing further downward pressure on natural gas prices, and has reduced the need for our coal-fired generation. Further, in the event that alternative generation resources, such as wind and solar, are mandated or otherwise subsidized or encouraged through climate legislation or regulation and added to the available generation supply, such resources could displace a higher marginal cost fossil plant, which could reduce the price at which market participants sell their electricity. This occurrence could then reduce the market price at which all generators in that region would be able to sell their output. These events could adversely affect our financial condition, results of operations and cash flows, and could also result in an impairment of certain long-lived assets.

In connection with these trading activities, weAEP routinely enterenters into financial contracts, including futures and options, over-the counter options, financially-settled swaps and other derivative contracts.  These activities expose usAEP to risks from price movements.  If the values of the financial contracts change in a manner we doAEP does not anticipate, it could harm our financial position or reduce the financial contribution of our trading operations.

Parties with whom we haveAEP has contracts may fail to perform their obligations, which could harm ourAEP’s results of operations. Affecting each Registrant(Applies to all Registrants)

We areAEP is exposed to the risk that counterparties that owe usAEP money or power could breach their obligations.  Should the counterparties to these arrangements fail to perform, weAEP may be forced to enter into alternative hedging arrangements or honor underlying commitments at then-current market prices that may exceed ourAEP’s contractual prices, which would cause our financial results to be diminished and weAEP might incur losses.  Although our estimates take into account the expected probability of default by a counterparty, our actual exposure to a default by a counterparty may be greater than the estimates predict.

We relyAEP relies on electric transmission facilities that we doAEP does not own or control.  If these facilities do not provide usAEP with adequate transmission capacity, weAEP may not be able to deliver our wholesale electric power to the purchasers of ourAEP’s power. Affecting each Registrant(Applies to all Registrants)

We dependAEP depends on transmission facilities owned and operated by other nonaffiliated power companies to deliver the power we sellAEP sells at wholesale.  This dependence exposes usAEP to a variety of risks.  If transmission is disrupted, or transmission capacity is inadequate, weAEP may not be able to sell and deliver ourAEP wholesale power.  If a region’s power transmission infrastructure is inadequate, ourAEP’s recovery of wholesale costs and profits may be limited.  If restrictive transmission price regulation is imposed, the transmission companies may not have sufficient incentive to invest in expansion of transmission infrastructure.

The FERC has issued electric transmission initiatives that require electric transmission services to be offered unbundled from commodity sales.  Although these initiatives are designed to encourage wholesale market transactions, access to transmission systems may in fact not be available if transmission capacity is insufficient because of physical constraints or because it is contractually unavailable.  WeManagement also cannot predict whether transmission facilities will be expanded in specific markets to accommodate competitive access to those markets.

OVEC may require additional liquidity and other capital support.  (Applies to AEP, APCo, I&M and OPCo)

AEP and several nonaffiliated utility companies own OVEC. The Inter-Company Power Agreement (ICPA) defines the rights and obligations and sets the power participation ratio of the parties to it.  Under the ICPA, parties are entitled to receive and are obligated to pay for all OVEC capacity (approximately 2,400 MW) in proportion to their respective power participation ratios. The aggregate power participation ratio of APCo, I&M and OPCo is 43.47%. If a party fails to make payments owed by it under the ICPA, OVEC may not have sufficient funds to honor its payment obligations, including its ongoing operating expenses as well as its indebtedness. OVEC has outstanding indebtedness of approximately $1.5 billion.



Recently, a nonaffiliated party to the ICPA announced its intention to exit its merchant business and that it may pursue restructuring or bankruptcy. This party’s aggregate power participation ratio is approximately 8% under the ICPA. As a result of this announcement and other related developments, Moody’s downgraded OVEC’s rating and left them on negative outlook for possible downgrade, Fitch revised OVEC’s outlook to negative, while S&P affirmed OVEC’s rating and stable outlook.

If OVEC does not have sufficient funds to honor its payment obligations, there is risk that APCo, I&M and/or OPCo may need to make payments in addition to their power participation ratio payments.  Further, if OVEC’s indebtedness is accelerated for any reason, there is risk that APCo, I&M and/or OPCo may be required to pay some or all of such accelerated indebtedness in amounts equal to their aggregate power participation ratio of 43.47%.  Also, as a result of the Moody’s and Fitch actions, OVEC’s ability to access capital markets on terms as favorable as previously may diminish and its financing costs may rise.

SYSTEM TRANSMISSION LINES AND FACILITY SITING

Laws in the states of Arkansas, Indiana, Kentucky, Louisiana, Michigan, Ohio, Tennessee, Texas, Virginia and West Virginia require prior approval of sites of generating facilities and/or routes of high-voltage transmission lines.  We haveAEP has experienced delays and additional costs in constructing facilities as a result of proceedings conducted pursuant to such statutes and in proceedings in which ourAEP’s operating companies have sought to acquire rights-of-way through condemnation.  These proceedings may result in additional delays and costs in future years.

CONSTRUCTION PROGRAM

With input from its state utility commissions, the AEP System continuously assesses the adequacy of its generation, transmission, distribution, generation and other facilities to plan and provide for the reliable supply of electric power and energy to its customers.  In this assessment process, assumptions are continually being reviewed as new information becomes available and assessments and plans are modified, as appropriate.  AEP forecasts approximately $4.5$5.7 billion of construction expenditures for 2015, including debt AFUDC and assets acquired under leases.2017. Estimated construction expenditures are subject to periodic review and modification and may vary based on the ongoing effects of regulatory constraints, environmental regulations, business opportunities, market volatility, economic trends, weather legal reviews and the ability to access capital.  For additional information on ourAEP’s construction program, see Combined Management’s Narrative Discussion and Analysis of Financial Condition and Results of Operations, included in the 2016 Annual Reports, under the heading entitled Budgeted Construction Expenditures for each Registrant.Expenditures.



POTENTIAL UNINSURED LOSSES

Some potential losses or liabilities may not be insurable or the amount of insurance carried may not be sufficient to meet potential losses and liabilities, including liabilities relating to damage to ourAEP’s generation plants and costs of replacement power.  Unless allowed to be recovered through rates, future losses or liabilities which are not completely insured could reduce net income and impact the financial conditions of AEP and other AEP System companies.  For risks related to owning a nuclear generating unit, see Note 6 to the consolidated financial statements entitled Commitments, Guarantees and Contingencies under the heading Nuclear Contingencies for information with respect to nuclear incident liability insurance.

During 2014,2016, management, including the principal executive officer and principal financial officer of each of American Electric Power Company, Inc. (“AEP”), Appalachian Power Company, Indiana Michigan Power Company, Ohio Power Company, Public Service Company of Oklahoma and Southwestern Electric Power Company (each a “Registrant” and collectively the “Registrants”) evaluated each respective Registrant’s disclosure controls and procedures.  Disclosure controls and procedures are defined as controls and other procedures of the Registrant that are designed to ensure that information required to be disclosed by the Registrants in the reports that they file or submit under the Exchange Act are recorded, processed, summarized, and reported within the time periods specified in the Commission’s rules and forms.  Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Registrants in the reports that they file or submit under the Exchange Act is accumulated and communicated to each Registrant’s management, including the principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

As of December 31, 2014,2016, these officers concluded that the disclosure controls and procedures in place are effective and provide reasonable assurance that the disclosure controls and procedures accomplished their objectives.  The Registrants continually strive to improve their disclosure controls and procedures to enhance the quality of their financial reporting and to maintain dynamic systems that change as events warrant.

There have been no changes in the Registrants’ internal control over financial reporting (as such term is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) during the fourth quarter 20142016 that materially affected, or is reasonably likely to materially affect, the Registrants’ internal control over financial reportingreporting.

Management assessed and reported on the effectiveness of its internal control over financial reporting as of December 31, 2014.2016.  As a result of that assessment, management determined that there were no material weaknesses as of December 31, 20142016 and, therefore, concluded that each Registrant’s internal control over financial reporting was effective.

Additional information required by this item of the Registrants is incorporated by reference to Management’s Report on Internal Control over Financial Reporting, included in the 20142016 Annual Report of each Registrant.

Basis of Presentation

The condensed financial information of AEP (Parent)Parent is required as a result of the restricted net assets of AEP consolidated subsidiaries exceeding 25% of AEP consolidated net assets as of December 31, 2014.2016.  Parent is a public utility holding company that owns all of the outstanding common stock of its public utility subsidiaries and varying percentages of other subsidiaries, including joint ventures and equity investments.  The primary source of income for Parent is equity in its subsidiaries’ earnings.  Its major source of cash is dividends from the subsidiaries.  Parent borrows the funds for the money pool that is used by the subsidiaries for their short-term cash needs.

Income Taxes

Parent files a consolidated federal income tax return with its subsidiaries.  AEP System’s current consolidated federal income tax is allocated to AEP System companies so that their current tax expense reflects a separate return result for each company in the consolidated group.  The tax benefit of Parent is allocated to its subsidiaries with taxable income.

2.  COMMITMENTS, GUARANTEES AND CONTINGENCIES

Parent and its subsidiaries are parties to environmental and other legal matters.  For further discussion of commitments, guarantees and contingencies, see Note 6 in the 20142016 Annual Reports.

4.  RELATED PARTY TRANSACTIONS

Payments on Behalf of Subsidiaries

Due to occasional time sensitivity and complexity of payments, Parent makes certain insurance, tax and benefit payments on behalf of subsidiary companies.  Parent is then fully reimbursed by the subsidiary companies.

Short-term Lending to Subsidiaries

Parent uses a commercial paper program to meet the short-term borrowing needs of subsidiaries.  The program is used to fund both a Utility Money Pool, which funds the utility subsidiaries, and a Nonutility Money Pool, which funds the majority of thecertain nonutility subsidiaries.  In addition, the program also funds, as direct borrowers, the short-term debt requirements of other subsidiaries that are not participants in either money pool for regulatory or operational reasons.  The program also allows some direct borrowers to invest excess cash with Parent.

Interest expense related to Parent’s short-term borrowing is included in Interest Expense on Parent’s statements of income.  Parent incurred interest expense for amounts borrowed from subsidiaries of $413 thousand, $7 thousand$2 million, $2 million and $11$413 thousand for the years ended December 31, 2014, 20132016, 2015 and 2012,2014, respectively.

Interest income related to Parent’s short-term lending is included in Interest Income on Parent’s statements of income.  Parent earned interest income for amounts advanced to subsidiaries of $4$10 million, $4 million and $5$4 million for the years ended December 31, 2014, 20132016, 2015 and 2012,2014, respectively.

Global Borrowing Notes

Parent issued long-term debt, portions of which were loaned to its subsidiaries.  Parent pays interest on the global notes, but the subsidiaries accrue interest for their share of the global borrowing and remit the interest to Parent.  Interest income related to Parent’s loans to subsidiaries is included in Interest Income on Parent’s statements of income.  Parent earned interest income on loans to subsidiaries of $3$1 million, $15$1 million and $15$3 million for the years ended December 31, 2016, 2015 and 2014, 2013 and 2012, respectively.
