Diversity of Regulated Assets

As the utility sector enters its first comprehensive capital expenditure

build-out since the 1980’s, many analysts project the industry to be cash flow
negative for the next few years

MEHC has no dividend requirement and therefore its 100% reinvestment of

free cash flow and access to equity capital from Berkshire under any market
condition clearly differentiates the quality of MEHC’s credit from its peers

MEHC’s Competitive Advantage

•

MEHC’s cash flow is derived from a diversified portfolio of businesses which

demonstrate low historical correlation amongst one another and macro economic
variables

•

Approximately 89% of MEHC’s operating income in 2006 was generated from

rate-regulated businesses

Alternative Regulation in Iowa

Case Study

•

Two independent prongs

–

Legislative – Rate-making principles (H.F. 577) apply to investor owned utilities in Iowa

–

Regulatory – Iowa Utilities Board (IUB) and Office of Consumer Advocate (OCA) are

receptive to rate-making proposals that are specific to a single utility

•

MEC has been successful with both

Case Study

Legislative Background

•

1984 – Significant costs related to newly-built generation were not allowed to be included

in rates, increasing risk of investing in the industry

Iowa enacted legislation that discouraged regulated utilities from building

generation

Incremental electric needs met through conservation, energy efficiency and

renewables

As a result, only one combustion turbine was added during the period (1984 -

2002)

•

1996 – Deregulation of the electric utility industry begins in California

•

1999 – Iowa decides not to follow popular nationwide trend toward electric industry

deregulation

•

2000 – Skyrocketing prices in the California market raise concerns about inadequacy of

generating capacity in the United States

MEC projected a need for new power plants to replace expiring power purchase

contracts and to satisfy load growth not met by energy efficiency and
renewables

2001 Legislative Debate

Case Study

•

Prior legislation and energy policy made power purchases from outside the state the

only cost-effective option for satisfying electric-supply needs

•

The legislature and the governor recognized the reliability and economic benefits of

additional rate-regulated generation being constructed in Iowa

•

MEC was asked what it would take to encourage the construction of regulated

generation in Iowa

•

The utilities, IUB, OCA, legislature and governor worked cooperatively to produce H.F.

577

Case Study

H.F. 577 Objective

•

H.F. 577 facilitates portfolio diversity by replacing the least-cost standard with a

reasonable cost standard

•

H.F. 577 mitigates regulatory risk and market price risk by providing for binding

regulatory review and determination of rate-making principles for proposed generation
investments prior to significant expenditures

–

Prudence review occurs prior to investment rather than after considerable investment

is made

•

A similar process is provided for investments in environmental improvements to

existing coal-fired generation

Case Study

H.F. 577 Rate-Making Principles

•

The rate-making principles process can be pursued at the option of the utility

•

The utility itself determines which rate-making principles are important to it for its

proposed investment

•

The generation facility must be located in Iowa and a baseload facility of at least 300

MW in size, a combined-cycle facility or a renewable facility

•

The utility must have in place an IUB-approved energy efficiency plan

•

The IUB is required to issue a decision on the principles

•

The rate-making principles apply for the life of the investment and are binding upon

future regulators

•

If the utility does not accept the rate-making principles as approved, the utility is not

required to pursue the project

Case Study

Revenue Sharing

•

The settlement of a contested case over MEC’s electric revenues in 1997 included:

–

Elimination of MEC’s fuel adjustment clause

–

An agreement that MEC and customers would share revenue above certain return on

equity (ROE) levels

–

Customer’s share was refunded through bill credits and checks

–

Refunds were given to customers related to earnings in years 1998 through 2000

•

MEC recognized that customers did not give long-term credit to rate reductions and bill

credits and that customers do not like rate increases

•

Because MEC would need to invest in new generation, increasing rate base by 65% over

six years, rate increases would be likely

•

Proposed to off-set the cost of new generation with the customers’ portion of revenue

sharing instead of providing bill credits or checks

•

Beginning with earnings from 2001, revenue-sharing dollars were applied to new

generation

•

Revenue sharing is specific to MEC through stipulation and agreement as approved by

the IUB, not by legislation

Case Study

MidAmerican Settlements

•

MEC is currently operating under a series of settlements that:

–

Provide rate-making principles for three major generation construction projects

•

Greater Des Moines Energy Center

•

Council Bluffs Energy Center Unit 4

•

Iowa Wind Projects

–

Allow returns over 11.75% to be shared between customers and MEC

•

11.75% - 13% share 40% customers / 60% company

•

13% - 14% share 50% customers / 50% company

•

Over 14% share 83.3% customers / 16.7% company

–

Customers’ share is used to off-set the cost of generation through 2010

•

As of December 31, 2006, customers’ share of revenue sharing has totaled $290 million

–

No general rate increase through at least 2012

–

If ROE falls below 10%, MEC may file for a rate increase

Case Study

Everyone Wins

•

Customers will face much smaller rate increases in the future

•

Customers enjoy the benefits of no general rate increase through at least 2012

•

Significant economic benefit to Iowa

•

IUB now has the legal authority to pre-approve without concerns about binding future boards

•

Significant new generation (over $2.5 billion in 6 years) is being, or has been, built in Iowa

–

Greater Des Moines Energy Center 491 MW Dec. 2004

–

Council Bluffs Energy Center Unit 4 790 MW June 2007

–

Iowa Wind Projects 583 MW 2004 – 2007

New Generation – Natural Gas

Greater Des Moines Energy Center is a 491 MW combined-cycle natural gas plant that was completed in December 2004

Council Bluffs Energy Center Unit 4

New Generation – Coal

Unit 4 to begin commercial operation in June 2007

New Generation – Coal

•

The Council Bluffs Energy Center Unit 4 is the largest power plant ever built in Iowa

•

The $1.2 billion, 790 MW facility uses advanced-supercritical coal-fueled technology

–

State-of-the-art power cycle design for high efficiency and low emissions per MWh

–

The plant applies the best available control technology to control air emissions and

meet or exceed all required standards for a new coal-fueled generation facility

–

First new coal-fueled plant in the United States with mercury control technology

•

A new 124 mile, 345kV transmission line and associated substation modifications were

completed in the summer of 2006 and will help to relieve transmission constraints and
improve transmission system reliability between Unit 4 and the central Iowa energy
market

TRANSACTIONS

Focused on ‘Wires Only’

•

Electricity distribution requires a licence enforced by the British regulator Ofgem

•

Licences oblige operators to transport electricity on non-discriminatory and

price-controlled terms on behalf of suppliers

•

Price controls are generally set for five years following a price control review, current

period extends to the end of March 2010

•

Metering is a separately price controlled activity and the services are provided through

a contract with a third party

Distribution Price Control Reviews

•

Price controls are set to recover Ofgem’s view of efficient costs over the next five years

•

Ofgem takes account of

–

Required quality of service outputs

–

Operating costs and comparative efficiency

–

Future capital expenditure

–

Regulatory asset value and depreciation

–

Pensions costs

–

(Forward) cost of capital

–

Tax

–

Financial ratios and investment grade rating targets

•

U.K. regulation tries to provide strong efficiency incentives for opex and capex

2005 – Initial request – filed May 2005

Revenue increase – $39.2 million or 17.9%

In April 2006 commission denied any rate relief

Commission rejected proposed allocation method finding a failure to demonstrate that all system resources benefited Washington customers

•

2006 – Initial request – filed October 2006

Revenue increase – $23.2 million or 10.2%

Proposed new west control area allocation method favored by staff

•

2006 – Current status

Staff supports PCAM

Staff testimony proposes a $12 million increase if the PCAM is adopted, $16 million if PCAM is not adopted

Industrial customer group and public counsel testimony proposes a $25 million rate reduction if PCAM is adopted

Company rebuttal proposes PCAM plus a $19 million increase

Hearings March 27 - 30; mid-year 2007 order expected

Oregon SB408

•

Attempts to match the amount of income “Taxes Collected” from customers to the amount of income “Taxes Paid,” as those terms are defined by the statute

Taxes Collected is determined by way of fixed reference to income tax expense expressed as a percentage of retail revenues as authorized by the commission in setting rates for the respective calendar year; percentage is applied to actual retail revenues to determine a hypothetical collection

Taxes Paid is computed as the lowest of 1) the stand-alone tax liability of the utility, 2) the tax liability of the consolidated group of which the utility is a member, or 3) the tax liability derived using the commission developed “Apportionment Method.”

Not an actual-to-actual comparison

•

If “Taxes Collected” and “Taxes Paid” vary by more than $100,000 the difference is either refunded or collected from customers

•

Oregon utilities are sponsoring legislation that would eliminate the hypothetical “Taxes Collected” formula and require the commission to compare actual taxes collected with taxes paid

•

Each affected utility submitted a request for a private letter ruling from the Internal Revenue Service to ensure the statute and its administrative rules comply with the normalization provisions of the Internal Revenue Code

Regulatory Strategy & Challenges

•

Recovering levels of investment which exceed depreciation and sales growth will require rate increases

–

Frequent large rate increases are not compatible with customer satisfaction goals

–

Low embedded generation cost compared to marginal generation cost, coupled with significant load growth, results in the need for more frequent rate increases

•

Implement effective relationship management

–

Communications plan

–

Relationship management plans for regulators, consumer groups and industrial consumer associations

•

Pursue alternative cost recovery mechanisms

–

Power cost adjustment mechanisms

–

Single item cost trackers (e.g., renewable investment)

–

Alternate forms of regulation

–

Implement use of future test periods in all states

•

Review and implement innovative cost-of-service and rate design methodologies

–

•

9-12 million tons of coal mined annually

•

6,104 MW coal-fired generation

•

1,702 MW gas-fired generation

•

Generation Investments

•

The embedded cost of generation in 2007 rates is approximately $34/MWh; whether new load is met by owned facilities or purchased power, that embedded cost is significantly below today’s marginal cost of power; as a result, the generation component of rates will increase as new power costs are reflected

–

New generation costs are significantly higher than embedded generation costs

•

New coal and gas plants cost approximately $60/MWh to $70/MWh on a levelized basis without carbon capture

•

New wind projects cost approximately $70/MWh after the production tax credit

–

Hydro capital costs will be $528 million over the next 10 years to meet FERC license requirements

•

New license implementation, excluding Klamath, will result in an output decrease of approximately 150 GWh per year

•

Klamath relicensing could result in an additional loss of 220 GWh or more, beginning in 2015

•

Swift #1 capacity increase of 75 MW, but small energy increase

•

2007 and 2008 generation capital spending projections do not reflect the decision to expedite the addition of renewable energy in those two years

Competitive Threats

and Opportunities

•

LNG on the West Coast

–

Competitive threat may be overstated

•

Schedule delays – particularly upstream liquefaction facilities and host country production sharing agreements

•

Reduced load factor expectations

•

Can North America compete for LNG supply?

Supply constraints in the winter

Sponge in the summer

•

Siting controversy continues to frustrate re-gasification proposals on the West Coast

•

Kern River is presently well positioned to compete if any California LNG re-gasification terminals are successful

Competitive Threats

and Opportunities

•

Potential impacts of Rockies Express

–

1,800 MDth/d of incremental Rocky Mountain supply heading east

–

Rocky Mountain production is currently pipeline capacity constrained

–

Kern River will compete with Rockies Express to attract supply

•

Wellhead net back will win the day

–

Full completion of Rockies Express is not scheduled until June 2009, but initial volumes are expected to flow to the mid-continent in 2008

–

Kern River anticipates Wyoming natural gas prices will increase due to increased access to premium eastern markets

–

Wyoming/California price spreads will narrow until production increases outstrip new pipeline takeaway capacity

–

Incremental Rocky Mountain production is expected to increase by 500-650 MDth per year over the next four years

–

Any impact on Kern River pricing is expected to be seasonal and temporary

Competitive Threats

and Opportunities

•

Growth in the West

–

California is captive to gas-fired generation

–

California ISO set an electric output record on July 24, 2006, which was not anticipated until 2011 (> 50,000 MW)

–

California is again short electric generation and is turning to natural gas to satisfy new electric demand

•

8,400 MW of new gas-fired electric generation is proposed in California

•

1,200 MW of new gas-fired electric generation is approved in Nevada

•

New delivery laterals and a capacity expansion are likely on Kern River by 2010

Phase 1

Global Climate Change Legislation

•

Transitioning to a low-carbon economy cannot take place overnight, but there are measures we should undertake now that will place us on the right path

•

We recommend a phased-in, technology and policy driven approach to provide tools necessary to successfully reduce long-term global greenhouse gas emissions while minimizing the costs and risks to the economy and the impact to customers

In the first phase, we suggest technology development and market transformation activities

•

Adoption of a flexible renewable and clean technology portfolio standard

•

More stringent energy efficiency mandates

•

Policies to encourage efficiency improvements at existing facilities

•

A ten-year, multi-billion dollar public-private research and development program for emissions reductions

•

Removal of the legal and regulatory barriers to the development of new technologies such as carbon sequestration and new nuclear development

•

Tax policies to support these programs, such as long-term energy tax credits

Phase 3

Phase 2

Global Climate Change Legislation

•

In the second phase, as technologies become widely available, a hybrid system of phased-in emissions reductions based on carbon intensity targets, together with a carbon price cap, would be developed

•

The third phase prescribes a 25 percent reduction of U.S. greenhouse gas emissions from 2000 levels by 2030, with additional reductions of 10 percent in each succeeding five-year period through 2050

Cautionary note about the cap and trade concept

•

Cap and trade is a useful tool but it is not a panacea

•

It does not supply emissions-free power

•

It does not bring new technologies on-line

•

It does not reduce prices for renewable energy resources

•

It merely raises prices for carbon-based emissions
