Cautionary Statement Regarding Forward-Looking Information

This Quarterly Report on Form 10-Q contains statements that are considered forward-looking statements within the meaning of the Securities Act of 1933 and the Securities Exchange Act of 1934.

·	adverse financial market conditions including changes in interest rates and the availability and cost of capital
·	adverse economic conditions
·	changes to prevailing local, state, and federal governmental policies and regulatory actions (including those of the DPU and the FERC) with respect to allowed rates of return, rate structure, continued recovery of regulatory assets and energy costs, financings, municipalization, acquisition and disposition of assets, operation and construction of facilities, changes in tax laws and policies, and changes in and compliance with environmental and safety laws and policies
·	new governmental regulations or changes to existing regulations that impose additional operating requirements or liabilities
·	changes in available information and circumstances regarding legal issues and the resulting impact on our estimated litigation costs
·	weather conditions that directly influence the demand for electricity
·	impact of continued cost control processes on operating results
·	ability to maintain current credit ratings
·	impact of uninsured losses
·	impact of adverse union contract negotiations
·	damage from major storms
·	impact of conservation measures and self-generation by our customers
·	changes in financial accounting and reporting standards
·	changes in hazardous waste site conditions and the cleanup technology
·	prices and availability of operating supplies
·	impact of terrorist acts and cyber-attacks, and
·	impact of service quality performance measures

Any forward-looking statement speaks only as of the date of this filing and NSTAR Electric undertakes no obligation to publicly update forward-looking statements, whether as a result of new information, future events, or otherwise. You are advised, however, to consult all further disclosures NSTAR Electric makes in its filings to the SEC. Other factors in addition to those listed here could also adversely affect NSTAR Electric.

Notes to Condensed Consolidated Financial Statements

(Unaudited)

The accompanying notes should be read in conjunction with Notes to Consolidated Financial Statements included in NSTAR Electric's 2009 Annual Report on Form 10-K.

Note A. Business Organization and Summary of Significant Accounting Policies

1. About NSTAR Electric

NSTAR Electric Company (NSTAR Electric or the Company) is a regulated public utility incorporated in 1886 under Massachusetts law and is a wholly-owned subsidiary of NSTAR. NSTAR Electric serves approximately 1.1 million electric distribution customers in the City of Boston and 80 surrounding communities. NSTAR is a holding company engaged through its subsidiaries in the energy delivery business serving approximately 1.4 million customers in Massachusetts, including NSTAR Electric’s customers and approximately 300,000 natural gas distribution customers in 51 communities. NSTAR has a service company that provides management and support services to substantially all NSTAR subsidiaries - NSTAR Electric & Gas.

Harbor Electric Energy Company (HEEC), a wholly-owned subsidiary of NSTAR Electric, provides distribution service and ongoing support to its only customer, the Massachusetts Water Resources Authority's wastewater treatment facility located on Deer Island in Boston, Massachusetts. NSTAR Electric’s three wholly-owned consolidated special-purpose subsidiaries are BEC Funding LLC, BEC Funding II LLC, and CEC Funding LLC, all established to facilitate the sales of electric rate reduction certificates at a public offering. The certificates of all special-purpose subsidiaries are secured by a portion of the transition charge assessed on NSTAR Electric's retail customers as permitted by the 1997 Massachusetts Electric Restructuring Act and authorized by the DPU. These certificates are non-recourse to NSTAR Electric. The activities of BEC Funding LLC were substantially completed as of March 31, 2010 and the Company was dissolved on April 14, 2010.

2. Basis of Consolidation and Accounting

The accompanying condensed consolidated financial information presented as of June 30, 2010 and for the three-month and six-month periods ended June 30, 2010 and 2009, has been prepared from NSTAR Electric's books and records without audit by an independent registered public accounting firm. However, NSTAR Electric's independent registered public accounting firm has performed a review of these interim financial statements in accordance with standards established by the PCAOB. The review report is filed as Exhibit 99.1 to this Form 10-Q. Financial information as of December 31, 2009 was derived from the audited consolidated financial statements of NSTAR Electric, but does not include all disclosures required by GAAP. In the opinion of NSTAR Electric's management, all adjustments (which are of a normal recurring nature) necessary for a fair presentation of the financial information for the periods indicated, have been included. All signific ant intercompany transactions have been eliminated in consolidation. Certain immaterial reclassifications have been made to the accompanying prior period Condensed Consolidated Statement of Cash Flow amounts to conform to the current period’s presentation.

NSTAR Electric follows accounting policies prescribed by the FERC and the DPU. In addition, NSTAR Electric is subject to the accounting and reporting requirements of the SEC. NSTAR Electric is subject to the application of ASC 980,Regulated Operations, that considers the effects of regulation resulting from differences in the timing of its recognition of certain revenues and expenses from those of other businesses and industries. The energy delivery business is subject to rate-regulation that is based on cost recovery and meets the criteria for application of ASC 980.

The preparation of financial statements in conformity with GAAP requires management of NSTAR Electric and its subsidiaries to make estimates and assumptions that affect the reported amounts of assets and

liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

The results of operations for the three-month and six-month periods ended June 30, 2010 and 2009 are not indicative of the results that may be expected for an entire year. The demand for electricity is affected by weather conditions, economic conditions, and consumer conservation behavior. Electric energy sales and revenues are typically higher in the winter and summer months than in the spring and fall months.

3. Pension and Postretirement Benefits Other than Pensions (PBOP) Plans

NSTAR Electric’s net periodic Pension Plan and PBOP Plan benefit costs for the second quarter are based on the latest available participant census data. An annual actuarial valuation was completed during the second quarter, and recognized costs were adjusted based on the final actuarial study results.

NSTAR Electric’s Pension Plan and NSTAR’s PBOP Plan assets, which partially consist of equity investments, are affected by the overall global equity markets. Fluctuations in the fair value of the Pension Plan and PBOP Plan assets impact the funded status, accounting costs, and cash funding requirements of these Plans. The earnings impact of changes in Pension and PBOP costs is substantially mitigated by NSTAR Electric’s DPU-approved Pension and PBOP rate adjustment mechanism (PAM).

Pension

NSTAR Electric is the sponsor of the NSTAR Pension Plan (the Plan), which is a defined benefit retirement plan that covers substantially all employees. As its sponsor, NSTAR Electric allocates the costs of the Plan to NSTAR Electric & Gas. NSTAR Electric & Gas charges all of its benefit costs to the NSTAR operating companies, including NSTAR Electric, based on the proportion of total direct labor charged to the Company. During the six months ended June 30, 2010, NSTAR contributed $6.3 million to the Plan. NSTAR contributed an additional $6.3 million to the Plan in July 2010 and currently anticipates contributing approximately $12.4 million to the Plan during the remainder of 2010. The actual level of funding may change depending on management’s assessment of market conditions.

Components of net periodic pension benefit cost were as follows:


		Three Months Ended						Six Months Ended
		June 30,						June 30,
(in millions)		2010			2009			2010			2009
Service cost	$	5.8		$	5.3		$	11.8		$	10.7
Interest cost		15.5			15.5			30.9			30.9
Expected return on Plan assets		(15.8	)		(14.8	)		(31.4	)		(29.1	)
Amortization of prior service cost		(0.2	)		(0.2	)		(0.4	)		(0.4	)
Recognized actuarial loss		12.7			13.3			25.2			26.6
Net periodic pension benefit cost	$	18.0		$	19.1		$	36.1		$	38.7

The first quarter net periodic pension cost is estimated utilizing projections based on the previous year’s liability and asset levels. The net periodic pension costs for the six months ended June 30, 2010 and 2009 have been adjusted in the second quarter to reflect the final actuarial study cost amounts for 2010 and 2009.

Postretirement Benefits Other than Pensions

NSTAR also provides health care and other benefits to retired employees who meet certain age and years of service eligibility requirements. Under certain circumstances, eligible retirees are required to contribute to the costs of postretirement benefits.

To fund these postretirement benefits, NSTAR, on behalf of NSTAR Electric and other NSTAR subsidiaries, makes contributions to various VEBA trusts that were established pursuant to section 501(c)(9) of the Internal Revenue Code.

NSTAR Electric participates in the Plan trusts with other NSTAR subsidiaries. Plan assets are available to provide benefits for all Plan participants who are former employees of NSTAR Electric and other subsidiaries of NSTAR. During the six months ended June 30, 2010, NSTAR contributed $14.4 million to this plan. NSTAR contributed an additional $2.4 million to the plan in July 2010 and currently anticipates contributing approximately $13.2 million to the plan during the remainder of 2010. NSTAR Electric will fund approximately $11.5 million, $1.9 million, and $10.6 million of these amounts, respectively. The actual level of funding may change depending on management’s assessment of market conditions.

NSTAR is evaluating the impact of the Patient Protection and Affordable Care Act of 2010 (PPACA) and the Health Care and Education Reconciliation Act of 2010 (HCERA) on its retiree health care benefits and accumulated PBOP obligation. To date, no adjustment has been made to NSTAR’s retiree benefit plan provisions or actuarial assumptions (including health care cost trend rates) as a result of PPACA and HCERA.

The net periodic postretirement benefit cost allocated to NSTAR Electric for the three-month and six-month periods ended June 30, 2010 was $8.6 million and $16.6 million, as compared to $8.3 million and $18 million in the three-month and six-month periods ended June 30, 2009.

5. Variable Interest Entities

Amended consolidation guidance applicable to variable interest entities became effective for NSTAR Electric on January 1, 2010. This amended guidance did not have an impact on the accompanying Condensed Consolidated Financial Statements.

NSTAR Electric has certain long-term purchase power agreements with energy facilities where it purchases substantially all of the output from a specified facility for a specified period. NSTAR Electric has evaluated these arrangements under the variable interest accounting guidance and has determined that these agreements represent variable interests. NSTAR Electric is not considered the primary beneficiary of these entities and does not consolidate the entities because it does not control the activities most relevant to the operating results of these entities and does not hold any equity interests in the entities. NSTAR Electric’s exposure to risks and financial support commitments with respect to these entities is limited to the purchase of the power generated at the prices defined under the contractual agreements. NSTAR Electric’s involvement with these variable interest entities has no material impact on NSTAR Electric’s fina ncial position, financial performance, or cash flows.

6. Subsequent Events

Management has reviewed subsequent events through the date of this filing and concluded that no material subsequent events have occurred that are not accounted for in the accompanying Condensed Consolidated Financial Statements or disclosed in the accompanying Notes to Condensed Consolidated Financial Statements.

Note B. Derivative Instruments

Energy Contracts

NSTAR Electric has determined that the majority of its electricity supply contracts qualify for, and NSTAR Electric has elected, the normal purchases and sales exception. As a result, these agreements are not reflected on the accompanying Condensed Consolidated Balance Sheets. NSTAR Electric has a long-term renewable energy contract that does not qualify for the normal purchases and sales exception and is valued at an estimated $2.5 million liability as of June 30, 2010. The value represents the difference between the cost of this contract and projected market energy costs over the life of the contract, and NSTAR Electric has recorded a long-term derivative liability and a corresponding long-term regulatory asset for the value of this contract. Changes in the value of the contract have no impact on earnings. The fair value of the renewable energy contract deemed to be a derivative is as follows:


(in thousands)		June 30, 2010		December 31, 2009
Renewable Energy Contracts – Non-hedging instruments
Consolidated Balance Sheet Account:
Deferred credits and other liabilities – Power contract obligations	$	2,483	$	-
Total liability for derivative instruments	$	2,483	$	-

Note C. Income Taxes

Effective Tax Rate

NSTAR Electric is part of a consolidated tax group. As such, income tax payments are either due to or from NSTAR (Holding Company).

The following table reconciles the statutory federal income tax rate to the annual estimated effective income tax rate for 2010 and the actual effective income tax rate for the year ended December 31, 2009:

Uncertain Tax Positions

As of June 30, 2010, the 2001 through 2007 Federal and state tax years remain open. NSTAR Electric has reached agreement on all issues and upon final resolution of an issue on an affiliated entity, NSTAR Electric will receive a written closing agreement from IRS Appeals. Upon the required approval of the settlement by the U.S. Congress Joint Committee on Taxation, NSTAR Electric expects receipt of the $128 million of its refundable income tax receivable, plus interest, in the second half of 2010. The 2008 Federal income tax return has been examined under the IRS Compliance Assurance Process (CAP) and NSTAR has received a “no change” letter. The 2009 Federal income tax return is being reviewed under CAP. This program accelerates the examination of the return in an attempt to resolve issues before the tax return is filed. The outcome of any potential audit adjustments and the timing are uncertain.

The following is a reconciliation of the unrecognized tax benefits that have been reflected as uncertain tax position liabilities on the accompanying Condensed Consolidated Balance Sheets included in Deferred credits and other liabilities: Other:


(in millions)		2010			2009
Balance at January 1	$	14		$	14
Changes for prior year tax positions		(14	)		-
Balance at June 30	$	-		$	14

During the second quarter of 2010, as a result of progress in ongoing settlement discussions with IRS Appeals, NSTAR Electric reversed reserves for uncertain tax positions of $14 million. As of June 30, 2010 and 2009, there were no unrecognized tax benefits of a permanent tax nature that if recognized would have an impact on the Company’s effective tax rate.

Interest on tax positions

NSTAR Electric recognizes interest accrued related to uncertain tax positions in: Interest income and other, net on the accompanying Condensed Consolidated Statements of Income. Related penalties, if applicable, are reflected in Other deductions, on the accompanying Condensed Consolidated Statements of Income.

For the six months ended June 30, 2010 and 2009, the amount of interest income recognized on the accompanying Condensed Consolidated Statements of Income was $6.7 million and $6.2 million, respectively, and the total amount of accrued interest receivable on the accompanying Condensed Consolidated Balance Sheets was $31.9 million and $25.2 million at June 30, 2010 and December 31, 2009, respectively. No penalties were recognized. During the second quarter of 2010, NSTAR Electric reversed approximately $6 million of previously accrued interest expense on various items because NSTAR Electric believes it is now more-likely-than-not that the original deductions will be sustained by IRS Appeals.

Unrecognized Tax Benefits

NSTAR Electric has unrecognized benefits associated with interest on construction-related uncertain tax positions. These unrecognized benefits were $4 million as of June 30, 2010 and December 31, 2009. As a result of the settlement agreement reached with IRS Appeals on SSCM, it is unlikely that these additional benefits will be recognized.

Note D. Fair Value Measurements

NSTAR Electric discloses fair value measurement pursuant to a framework for measuring fair value in accordance with GAAP. NSTAR Electric follows a fair value hierarchy that prioritizes the inputs used to determine fair value and requires the Company to classify assets and liabilities carried at fair value based on the observability of these inputs. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The three levels of the fair value hierarchy are:

Level 1 – Unadjusted quoted prices available in active markets for identical assets or liabilities as of the reporting date. Financial assets utilizing Level 1 inputs include active exchange-traded equity securities.

Level 2 – Quoted prices available in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, inputs other than quoted prices that are directly observable, and inputs derived principally from market data.

Level 3 – Unobservable inputs from objective sources. These inputs may be based on entity-specific inputs. Level 3 inputs include all inputs that do not meet the requirements of Level 1 or Level 2.

The renewable energy contract was valued based on the difference between the contracted price and the estimated fair value of remaining contracted supply to be purchased. Inputs used to develop the estimate included on-line regional generation and forecasted demand.

The following represents the fair value hierarchy of NSTAR Electric’s financial liability that was recognized at fair value on a recurring basis as of June 30, 2010. Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement.


Recurring Fair Value Measures:

Fair Value of Financial Instruments

The carrying amounts for cash and cash equivalents, net accounts receivable, other current assets, certain current liabilities, and notes payable as of June 30, 2010 and December 31, 2009, respectively, approximate fair value due to the short-term nature of these securities.

The fair values of long-term indebtedness (excluding notes payable, including current maturities) are based on the quoted market prices of similar issues. Carrying amounts and fair values as of June 30, 2010 and December 31, 2009 were as follows:


		June 30, 2010				December 31, 2009
(in thousands)		Carrying Amount		Fair Value		Carrying Amount		Fair Value

Long-term indebtedness (including current maturities)	$	1,839,515	$	2,029,960	$	1,717,588	$	1,801,910

Note E. Long-Term Debt Issuance and Retirement

On March 15, 2010, NSTAR Electric’s subsidiary BEC Funding LLC, retired its final series of outstanding Transition Property Securitization Certificates. On March 16, 2010, NSTAR Electric issued, at a discount, $300 million of 5.50% Debentures due 2040. The proceeds from this sale were used to retire NSTAR

Electric’s short-term debt and for other corporate purposes. On May 17, 2010, NSTAR Electric retired its $125 million, 7.8% Debentures as scheduled.

Note F. Commitments and Contingencies

1. Service Quality Indicators

SQI are established performance benchmarks for certain identified measures of service quality relating to customer service and billing performance, safety and reliability and DPU Consumer Division statistics performance for all Massachusetts utilities. NSTAR Electric is required to report annually to the DPU concerning its performance as to each measure and is subject to maximum penalties of up to two and one-half percent of total transmission and distribution revenues should performance fail to meet the applicable benchmarks.

NSTAR Electric monitors its service quality continuously to determine if a liability has been triggered. If it is probable that a liability has been incurred and is estimable, a liability is accrued. Annually, NSTAR Electric makes a service quality performance filing with the DPU. Any settlement or rate order that would result in a different liability level from what has been accrued would be adjusted in the period that the DPU issues an order determining the amount of any such liability.

NSTAR Electric’s service quality performance levels for 2009 were not in a penalty situation and the final performance report was filed with the DPU on March 1, 2010.

2. Environmental Matters

NSTAR Electric faces possible liabilities as a result of involvement in several multi-party disposal sites, state-regulated sites or third party claims associated with contamination remediation. NSTAR Electric generally expects to have only a small percentage of the total potential liability for the majority of these sites. As of June 30, 2010 and December 31, 2009, NSTAR Electric had liabilities of approximately $0.9 million and $0.8 million, respectively, for these environmental sites. This estimated recorded liability is based on an evaluation of all currently available facts with respect to these sites.

Estimates related to environmental remediation costs are reviewed and adjusted as further investigation and assignment of responsibility occurs and as either additional sites are identified or NSTAR Electric's responsibilities for such sites evolve or are resolved. NSTAR Electric's ultimate liability for future environmental remediation costs may vary from these estimates. Based on NSTAR Electric's current assessment of its environmental responsibilities, existing legal requirements, and regulatory policies, NSTAR Electric does not believe that these environmental remediation costs will have a material adverse effect on NSTAR Electric's consolidated results of operations, financial position, or cash flows.

3. DPU Safety and Reliability Programs (CPSL)

As part of the Rate Settlement Agreement, NSTAR Electric is allowed to recover incremental costs related to the double pole inspection, replacement/restoration and transfer program and the underground electric safety program, which includes stray-voltage remediation and manhole inspections, repairs, and upgrades. Recovery of these Capital Program Scheduling List (CPSL) billed costs is subject to DPU review and approval. NSTAR Electric incurred and billed incremental costs of $12 million, $14 million, $15 million and $16 million in 2006, 2007, 2008 and 2009, respectively. During 2010, approximately $9 million has been incurred through June 30. This includes incremental operations and maintenance and revenue requirements on capital investments.

cost recovery through 2009. NSTAR Electric cannot predict the timing of subsequent DPU orders related to these pending filings. Should an adverse DPU decision be issued, it could have a material adverse impact on NSTAR Electric’s results of operations, financial position, and cash flows.

4. Basic Service Bad Debt Adder

On July 1, 2005, in response to a generic DPU order that required electric utilities in Massachusetts to recover the energy-related portion of bad debt costs in their Basic Service rates, NSTAR Electric increased its Basic Service rates and reduced its distribution rates for those bad debt costs. In furtherance of this generic DPU order, NSTAR Electric included a bad debt cost recovery mechanism as a component of its Rate Settlement Agreement. This recovery mechanism (bad debt adder) allows NSTAR Electric to recover its Basic Service bad debt costs on a fully reconciling basis. These rates were implemented, effective January 1, 2006, as part of NSTAR Electric’s Rate Settlement Agreement.

On February 7, 2007, NSTAR Electric filed its 2006 Basic Service reconciliation with the DPU proposing an adjustment related to the increase in its Basic Service bad debt charge-offs. This proposed rate adjustment was anticipated to be implemented effective July 1, 2007. On June 28, 2007, the DPU issued an order approving the implementation of a revised Basic Service rate. However, the DPU instructed NSTAR Electric to reduce distribution rates by the increase in its Basic Service bad debt charge-offs. Such action would result in a further reduction to distribution rates from the adjustment NSTAR Electric made when it implemented the Settlement Agreement. This adjustment to NSTAR Electric’s distribution rates would eliminate the fully reconciling nature of the Basic Service bad debt adder.

NSTAR Electric has not implemented the directives of the June 28, 2007 DPU order. Implementation of this order would require NSTAR Electric to write-off a previously recorded regulatory asset related to its Basic Service bad debt costs. NSTAR Electric filed a Motion for Reconsideration of the DPU’s order on July 18, 2007. On December 14, 2007, the Motion for Reconsideration was granted and the DPU reopened the case to hear additional evidence. NSTAR Electric filed additional testimony in April 2008, an evidentiary hearing was held, and briefs were filed in June and early July 2008.

On May 28, 2010, the DPU issued an order and reaffirmed that NSTAR Electric should reduce its distribution rates by the increase in its Basic Service bad debt charge-offs. NSTAR Electric continues to believe that its position is appropriate and that it is probable upon appeal that it will ultimately prevail. On June 18, 2010, NSTAR Electric filed with the Massachusetts Supreme Judicial Court to appeal the DPU’s decisions. On June 25, 2010, NSTAR Electric filed with the Massachusetts Supreme Judicial Court to seek a stay of execution of the distribution rate reduction requirement pending the appeal. As of June 30, 2010, the potential impact to earnings of eliminating the bad debt adder would be approximately $22.3 million, pre-tax. NSTAR Electric cannot predict the timing of this appeals process.

5. Yankee Companies Spent Fuel Litigation

In October 2006, the U.S. Court of Federal Claims issued a judgment in a spent nuclear fuel litigation in the amounts of $34.2 million, $32.9 million, and $75.8 million for Connecticut Yankee Atomic Power Company (CY), Yankee Atomic Electric Company (YA), and Maine Yankee Atomic Power Company (MY), respectively. This judgment in favor of the Yankee Companies relates to the alleged failure of the Department of Energy (DOE) to provide for a permanent facility to store spent nuclear fuel for years prior to 2001 for CY and YA, and prior to 2002 for MY (DOE Phase I Damages). NSTAR Electric’s portion of the Phase I judgments amounts to $4.8 million, $4.6 million, and $3 million, respectively. On July 1, 2009, the Yankee Companies filed for additional damages related to the alleged failure of the DOE to provide for a permanent facility to store spent nuclear fuel for the years from January 2002 through December 2008 for CY and YA, and from January 2003 through December 2008 for MY (DOE Phase II Damages). This phase of the spent nuclear fuel litigation specifies damages in the amounts of $135.4 million, $86.1 million, and $43 million for CY, YA, and MY, respectively. Claim amounts applicable to NSTAR Electric are $19 million, $12 million, and $1.7 million, respectively.

NSTAR Electric cannot predict the ultimate outcome of these pending decisions for trial, appeal or the potential subsequent complaints. However, should the Yankee Companies ultimately prevail, NSTAR Electric’s share of the proceeds received would be refunded to its customers.

6. Legal Matters

In the normal course of its business, NSTAR Electric and its subsidiaries are involved in certain legal matters, including civil litigation. Management is unable to fully determine a range of reasonably possible court-ordered damages, settlement amounts, and related litigation costs (“legal liabilities”) that would be in excess of amounts accrued and amounts covered by insurance. Based on the information currently available, NSTAR Electric does not believe that it is probable that any such legal liabilities will have a material impact on its consolidated financial position. However, it is reasonably possible that additional legal liabilities that may result from changes in circumstances could have a material impact on its results of operations, financial condition, and cash flows.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations (MD&A)

The accompanying MD&A focuses on factors that had a material effect on the financial condition, results of operations, and cash flows of NSTAR Electric during the periods presented and should be read in conjunction with the accompanying Condensed Consolidated Financial Statements and accompanying Notes to Condensed Consolidated Financial Statements, and with the MD&A in NSTAR Electric's 2009 Annual Report on Form 10-K.

Business Overview

NSTAR Electric Company is a regulated public utility incorporated in 1886 under Massachusetts law and is a wholly-owned subsidiary of NSTAR. NSTAR Electric serves approximately 1.1 million electric distribution customers in the City of Boston and 80 surrounding communities. NSTAR is a holding company engaged through its subsidiaries in the energy delivery business serving approximately 1.4 million customers in Massachusetts, including NSTAR Electric's customers and approximately 300,000 natural gas distribution customers in 51 communities. NSTAR has a service company that provides management and support services to substantially all NSTAR subsidiaries - NSTAR Electric & Gas.

Harbor Electric Energy Company (HEEC), a wholly owned-subsidiary of NSTAR Electric, provides distribution service and ongoing support to its only customer, the Massachusetts Water Resources Authority's wastewater treatment facility located on Deer Island in Boston, Massachusetts. NSTAR Electric's three wholly-owned consolidated special-purpose subsidiaries are BEC Funding LLC (BEC Funding), BEC Funding II, LLC (BEC Funding II) and CEC Funding, LLC (CEC Funding), all established to facilitate the sales of electric rate reduction certificates at a public offering. The certificates of all special-purpose subsidiaries are secured by a portion of the transition charge assessed on NSTAR Electric's retail customers as permitted by the 1997 Massachusetts Electric Restructuring Act and authorized by the DPU. These certificates are non-recourse to NSTAR Electric. The activities of BEC Funding LLC were substantially completed as of March 31, 2010 and the Company was dissolved on April 14, 2010.

NSTAR Electric derives its operating revenues primarily from the sale of energy, distribution, transmission, and energy efficiency services to customers. However, NSTAR Electric's earnings are impacted by fluctuations in unit sales of electric kilowatt-hours, which have an effect on the level of distribution and transmission revenues recognized. In accordance with the regulatory rate structure in which NSTAR Electric operates, its recovery of energy and energy-related costs are fully reconciled with the level of energy revenues currently recorded and, therefore, do not have an impact on earnings. As a result of this rate structure, any variability in the cost of energy supply purchased will have an impact on purchased power and transmission expenses, but will not affect the Company's net income as the Company recognizes a corresponding change in revenues.

Earnings

NSTAR Electric's earnings are impacted by its customers’ requirements for energy in the form of unit sales of electricity, which directly determine the levels of retail distribution and transmission revenues recognized. In accordance with the regulatory rate structures in which NSTAR Electric operates, its recovery of energy and energy-related costs are fully reconciled with the level of energy revenues currently recorded and, therefore, do not have an impact on earnings.

Net income for the three-month and six-month periods ended June 30, 2010 was $62.7 million and $105.4 million, respectively, as compared to $59.2 million and $103.1 million, respectively, for the same period in 2009, as further explained below.

Critical Accounting Policies and Estimates

For a complete discussion of critical accounting policies, refer to "Critical Accounting Policies and Estimates" in Item 7 of NSTAR Electric's 2009 Form 10-K. There have been no substantive changes to those policies and estimates.

Rate Structure

a. Rate Settlement Agreement

NSTAR Electric is currently operating under a DPU-approved seven-year Rate Settlement Agreement (Rate Settlement Agreement) that expires December 31, 2012. From 2007 through 2012, the Rate Settlement Agreement establishes for NSTAR Electric, among other things, annual inflation-adjusted distribution rates that are generally offset by an equal and corresponding reduction in transition rates. The increase adjustment is 1.32% effective January 1, 2010; and corresponding adjustments were 1.74%, 2.68%, and 2.64% effective January 1, 2009, 2008, and 2007, respectively. Uncollected transition charges as a result of the reductions in transition rates are deferred and collected through future rates with a carrying charge.

b. Electric Rates

Retail electric delivery rates are established by the DPU and are comprised of:


·	a distribution charge, which includes a fixed customer charge and a demand and/or energy charge (to collect the costs of building and expanding the infrastructure to deliver power to its destination, as well as ongoing operating costs and certain DPU-approved safety and reliability programs costs), a Pension and PBOP Rate Adjustment Mechanism (PAM) to recover incremental pension and pension benefit costs and a reconciling rate adjustment mechanism to recover costs associated with the residential assistance adjustment clause, and an Energy Efficiency Reconciling Factor (EERF) to recover energy efficiency expenditures in addition to those charges recovered in the energy conservation change;
·	a basic service chargerepresents the collection of energy costs, including costs related to charge-offs of uncollected energy costs, through DPU-approved rate mechanisms. Electric distribution companies in Massachusetts are required to obtain and resell power to retail customers through Basic Service for those who choose not to buy energy from a competitive energy supplier. Basic Service rates are reset every six months (every three months for large commercial and industrial customers). The price of Basic Service is intended to reflect the average competitive market price for electric power;
·	a transition charge represents the collection of costs primarily from previously held investments in generating plants and costs related to existing above-market power contracts, and contract costs related to long-term power contracts buy-outs;
·	a transmission charge represents the collection of costs of moving the electricity over high voltage lines from generating plants to substations located within NSTAR Electric’s service area including costs allocated to NSTAR Electric by ISO-NE to maintain the wholesale electric market;
·	an energy conservation chargerepresents a legislatively-mandated charge to collect costs for energy efficiency programs; and
·	a renewable energy charge represents a legislatively-mandated charge to collect the costs to support the development and promotion of renewable energy projects.

c. Regulatory Matters

DPU Safety and Reliability Programs (CPSL)

On May 28, 2010, the DPU issued an order on NSTAR Electric’s 2006 CPSL costs recovery filing. This order addressed the cost recovery of NSTAR Electric’s 2006 CPSL program. The expected recovery amount does not vary materially from the revenue previously recognized. During the fourth quarter of 2010, NSTAR Electric expects to make supplemental filings in compliance with the DPU order to address cost recovery through 2009. NSTAR Electric cannot predict the timing of subsequent DPU orders related to these pending filings. Should an adverse DPU decision be issued, it could have a material adverse impact on NSTAR Electric’s results of operations, financial position, and cash flows.

Basic Service Bad Debt Adder

FERC Transmission ROE

NSTAR Electric earns an 11.14% ROE on local transmission facility investments. The ROE on NSTAR Electric’s regional transmission facilities is 11.64%. Additional incentive adders are determined on a case-by-case basis according to FERC’s national transmission incentive rules. The FERC may grant a variety of financial incentives, including ROE basis point incentive adders for qualified investments made in new regional transmission facilities that can bring the ROE for NSTAR Electric up to 13.1% for certain qualified regional investments.

Other

a. Energy Efficiency Plans

NSTAR Electric is required to administer an energy efficiency program. The Massachusetts Green Communities Act (GCA) required electric distribution companies to develop three-year energy efficiency plans. The first three-year plan effective in 2010 is expected to lead to a significant expansion of energy efficiency activity in Massachusetts. Like the historical programs, the new three-year plan includes financial incentives based on energy efficiency program performance and spending. In addition, the DPU has stated that it will permit distribution companies like NSTAR Electric that do not yet have rate decoupling mechanisms in place to implement lost base revenue rate adjustment mechanisms that will partially offset reduced distribution rate revenues as a result of successful energy efficiency programs.

NSTAR Electric has filed its 2010 Energy Efficiency Plan and anticipates that the program will amount to about $122 million in spending, including incentives. This 2010 plan was approved by the DPU on January 28, 2010.

b. Proposed Transmission Investments

ISO-NE has included in its regional system plan a new twenty-two mile 345kV transmission line that will cross the Cape Cod Canal. This project involves the expansion and upgrade of existing transmission infrastructure. NSTAR Electric is pursuing the license approval of this project, as well as preparing cost allocation and reliability applications with ISO-NE. This project is anticipated to cost approximately $120 million and be in-service in 2012.

Results of Operations

The following section of MD&A compares the results of operations for each of the three-month and six-month periods ended June 30, 2010 and 2009 and should be read in conjunction with the accompanying Condensed Consolidated Financial Statements and the accompanying Notes to Condensed Consolidated Financial Statements included elsewhere in this report.

Three Months Ended June 30, 2010 compared to Three Months Ended June 30, 2009

Executive Summary of Quarterly Results

Net income was $62.7 million for the three months ended June 30, 2010 compared to $59.2 million for the same period in 2009. Major factors on an after-tax basis that contributed to the $3.5 million, or 5.9%, increase include:


·	Higher distribution revenues due to a 5.9% increase in sales and the annual inflation rate adjustment ($10.3 million)
·	Higher transmission revenues ($2.1 million)
·	Lower costs to achieve amortization ($2.1 million)

These increases in earnings factors were partially offset by:


·	Higher net interest charges ($1.5 million)
·	Cumulative impact of a true-up adjustment resulting from a DPU order on May 28, 2010 related to NSTAR Electric’s transition mitigation incentive for the years 2006-2009 ($3 million)
·	Higher operations and maintenance expense ($0.5 million)
·	Higher depreciation and property taxes ($2.8 million)

Significant cash flow events during the quarter include the following:


·	Cash flows from operating activities provided approximately $53 million, an increase of $3 million as compared to the same period in 2009. The increase primarily reflects the timing of payments and customer collections related to energy costs partially offset by the higher level of income tax payments
·	Cash outflows for investing activities include approximately $66 million in capital projects to improve system reliability and capacity
·	Cash outflows from financing activities included $29 million in common share dividends and retirement of approximately $144 million in long-term and securitized debt

Energy sales

The following is a summary of retail electric energy sales for the periods indicated:


Retail Electric Sales - MWh	Three Months Ended June 30,
	2010	2009	% Change

Residential	1,508,700	1,390,494	8.5
Commercial, Industrial, and Other	3,610,897	3,443,658	4.9
Total retail sales	5,119,597	4,834,152	5.9

NSTAR Electric’s energy sales in the three months ended June 30, 2010 increased 5.9% compared to 2009 primarily due to favorable weather conditions resulting from warmer weather in May and June 2010 as compared to 2009. Cooling degree-days in NSTAR Electric’s service area for the three months ended June 30, 2010 were up nearly 228% from the same period in 2009.

Primarily weather, but also to a lesser extent fluctuations in fuel costs, conservation measures, and economic conditions affect sales to NSTAR Electric’s residential and small commercial customers. Economic conditions, fluctuations in fuel costs, and conservation measures affect NSTAR Electric’s large commercial and industrial customers. In terms of customer sector characteristics, industrial sales are less sensitive to weather than residential and commercial sales, which are influenced by temperature variations. Refer to the“Operating Revenues” section below for a more detailed discussion.

Weather conditions

NSTAR Electric forecasts its electric sales based on normal weather conditions. Actual results may vary from those projected due to actual weather conditions, energy conservation, and other factors. Refer to the“Cautionary Statement Regarding Forward-Looking Information” section preceding Part 1“Financial Information” of this Form 10-Q.

The demand for electricity is affected by weather. Weather impacts electric sales primarily during the summer. Customer heating or cooling usage may not directly correlate with historical levels or with the level of degree-days that occur (as further discussed below), particularly when weather patterns experienced are consistently colder or warmer. Also, NSTAR Electric’s business is sensitive to variations in daily weather, is highly influenced by New England’s seasonal weather variations, and is susceptible to severe storm-related incidents that could adversely affect the Company’s ability to provide energy.

Degree-days measure changes in daily mean temperature levels. A degree-day is a unit measuring how many degrees the outdoor daily mean temperature falls below (in the case of heating) or rises above (in the case of cooling) a base of 65 degrees. The comparative information below relates to heating and cooling degree-days for the three-month periods ended June 30, 2010 and 2009 and the number of heating and cooling degree-days in a “normal” second quarter as presented by a 30-year average. NSTAR uses the “normal 30-year average” degree-days data to compare current temperature readings to a baseline or “normal” period, that is recalculated every ten years for the preceding 30 years (currently 1980-2009), as collected at the Worcester, Massachusetts airport and Boston’s Logan airport for both heating and cooling degree-day data. As shown in the table below, weather conditions during the three-month period ended J une 30, 2010 measured by heating and cooling degree-days, respectively, were 29.7% lower/warmer related to heating degree-days and 227.8% higher/warmer related to cooling degree-days for 2010 as compared to 2009, favorably impacting revenues. Refer to the“Electric Revenues” section below for more detailed discussions.


Heating Degree-Day (HDD)
Three months ended June 30, 2010	503
Three months ended June 30, 2009	716
Normal 30-Year Average	784
Percentage that 2010 HDD were higher than 2009	29.7	%
Percentage that 2010 HDD were higher than 30-year average	35.8	%

Cooling Degree-Days (CDD)
Three months ended June 30, 2010	259
Three months ended June 30, 2009	79
Normal 30-Year Average	175
Percentage that 2010 CDD were higher than 2009	227.8	%
Percentage that 2010 CDD were higher than 30-year average	48	%

Operating revenues

Operating revenues for the second quarter of 2010 decreased $28 million, or 5%, from the same period in 2009 as follows:


(in millions)		Three Months Ended June 30,				Increase (Decrease)
Operating revenues		2010		2009		Amount		Percent

Retail distribution and transmission	$	282.7	$	245.8	$	36.9		15	%
Energy, transition, and other		296.2		361.1		(64.9	)	(18	)%
Total operating revenues	$	578.9	$	606.9	$	(28.0	)	(5	)%

NSTAR's largest earnings sources are the revenues derived from distribution and transmission rates approved by the DPU and the FERC. Electric retail distribution revenues primarily represent charges to customers for recovery of the Company's capital investment, including a return component, and operation and maintenance costs related to its electric distribution infrastructure. The transmission revenue component represents charges to customers for the recovery of similar costs to move the electricity over high voltage lines from the generator to the Company's distribution substations.

The increase of $36.9 million, or 15%, in retail distribution and transmission revenues primarily reflects:


·	Higher distribution revenues attributable to a 5.9% increase in sales, in addition to an increase resulting from the annual inflation rate adjustment ($16.9 million)
·	Increased transmission revenues primarily due to the recovery of a higher transmission investment base, including higher depreciation and property taxes and recovery of higher regional network service and other costs ($16.3 million)

Energy, transition, and other revenues primarily represent charges to customers for the recovery of costs incurred by the Company in order to acquire the energy supply on behalf of its customers and a transition charge for recovery of the Company's prior investments in generating plants and the costs related to long-term power contracts. The energy revenues relate to customers being provided energy supply under Basic Service. These revenues are fully reconciled to the costs incurred and have no impact on NSTAR's consolidated net income. Energy, transition, and other revenues also reflect revenues related to the Company's ability to effectively reduce stranded costs (incentive entitlements), rental revenue from electric property, and annual cost reconciliation true-up adjustments. The $64.9 million decrease in energy, transition, and other revenues is primarily attributable to lower Basic Service rates in effect due to lower energy costs. Uncollected transition costs as a result of the reductions in transition rates are deferred and collected through future rates with a carrying charge.

Operating expenses

Purchased power and transmission expense was $268.2 million in the second quarter of 2010 compared to $299.1 million in the same period of 2009, a decrease of $30.9 million, or 10.3%. The decrease in expense reflects lower Basic Service and other energy costs of $43.8 million. These decreases were partially offset by higher transmission costs of $12.9 million due to an increase in regional network support costs. NSTAR Electric adjusts its rates to collect the costs related to energy supply from customers on a fully reconciling basis. Due to this rate adjustment mechanism, changes in the amount of energy supply expense have no impact on consolidated net income.

Operations and maintenance expensewas $78 million in the second quarter of 2010 compared to $74 million in the same period of 2009, an increase of $4 million, or 5.4%. The increase in expense reflects higher pension and PBOP related PAM amortization costs ($2.8 million). Fluctuations in PAM amortization do not have an earnings impact as these costs are fully recovered from customers. Also contributing to the higher expense was higher bad debts expense ($1 million) and higher storm-related costs ($0.5 million).

Depreciation and amortization expense was $67.1 million in the second quarter of 2010 compared to $85.4 million in the same period of 2009, a decrease of $18.3 million, or 21.4%. The decrease primarily reflects the completion of the 10-year amortization related to merger integration costs and lower amortization costs related to the pay-down of securitized debt, offset by higher depreciable distribution and transmission plant-in-service.

Energy efficiency and renewable energy programs expensewas $22 million in the second quarter of 2010 compared to $17.2 million in the same period of 2009, an increase of $4.8 million, or 27.9%, which is consistent with the collection of conservation and renewable energy revenues. These costs are in accordance with program guidelines established by the DPU and are collected from customers on a fully reconciling basis plus a performance incentive. NSTAR Electric anticipates a further increase in Energy Efficiency spending during 2010 and in future years driven by requirements of the Green Communities

Act (GCA). Those spending increases are expected to be funded partially through proceeds from the Regional Greenhouse Gas Initiative and through NSTAR Electric’s participation in the Forward Capacity Market.

Property and other taxes expense was $24.3 million in the second quarter of 2010 compared to $21.7 million in the same period of 2009, an increase of $2.6 million, or 12%, reflecting higher overall property investments and higher tax rates.

Interest charges (income):

Long-term debt and transition property securitization certificateinterest charges were $26.7 million in the second quarter of 2010 compared to $25.9 million in the same period of 2009, an increase of $0.8 million, or 3.1%. The increase in interest charges reflects the issuance of $300 million of 5.5% Debentures in March 2010, partially offset by pay downs of $125 million of 7.8% Debentures in May 2010 and scheduled principal pay downs of transition property securitization debt.

Interest income and other, net were $11.3 million of net interest income in the second quarter of 2010 compared to $10.9 million of net interest income in the same period of 2009, an increase of $0.4 million, or 3.7%, due to higher interest income on income tax matters of $0.9 million and lower average level of funds borrowed.

Other income (deductions):

Other income was approximately $1.2 million in the second quarter of 2010 compared to $2.2 million in the same period of 2009, a decrease of $1 million, or 45%. The decrease relates primarily to lower cash surrender values of insurance policies.

Other deductions was $0.4 million in the second quarter of 2010 compared to $0.5 million in the same period of 2009.

Income tax expense:

Income tax expense was $41.9 million in the second quarter of 2010 compared to $37.1 million in the same period of 2009, an increase of $4.8 million, or 12.9%, due to higher pre-tax operating income.

Six Months Ended June 30, 2010 compared to Six Months Ended June 30, 2009

Executive Summary of Quarterly Results

Net income was $105.4 million for the six months ended June 30, 2010 compared to $103.1 million for the same period in 2009. Major factors on an after-tax basis that contributed to the $2.3 million, or 2.2%, increase include:


·	Higher distribution revenues due to a 1.7% increase in sales and the annual inflation rate adjustment ($9 million)
·	Higher transmission revenues ($3.5 million)
·	Lower costs to achieve amortization ($4.3 million)

These increases in earnings factors were partially offset by:


·	Higher net interest charges ($1.4 million)
·	Cumulative impact of a true-up adjustment resulting from a DPU order on May 28, 2010 related to NSTAR Electric’s transition mitigation incentive for the years 2006-2009 ($3 million)
·	Higher operations and maintenance expense ($3.2 million)
·	Higher depreciation and property taxes ($4.9 million)

Significant cash flow events during the six months ended June 30, 2010 include the following:


·	Cash flows from operating activities provided $145.4 million, a decrease of $101.7 million as compared to the same period in 2009. The decrease primarily reflects the timing of payments and customer collections related to energy costs and higher income tax payments
·	Cash flows from investing activities included $136.2 million in capital projects to improve system reliability and capacity
·	Cash outflows from financing activities included retirement of $173.4 million in long-term and securitized debt and $131.6 million in common share dividends. Significant inflows included the issuance of $300 million of 5.50% Debentures with an effective rate of 5.61%

Energy sales

The following is a summary of retail electric energy sales for the periods indicated:

Item 4. Controls and Procedures

NSTAR Electric's disclosure controls and procedures are designed to ensure that information required to be disclosed in reports that it files or submits under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission.

As of the end of the period covered by this Quarterly Report on Form 10-Q, NSTAR Electric carried out an evaluation, under the supervision and with the participation of NSTAR Electric's management, including NSTAR Electric's Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of NSTAR Electric's disclosure controls and procedures pursuant to Securities Exchange Act of 1934 Rules 13a-15(e) or 15d-15(e). Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that NSTAR Electric's disclosure controls and procedures were effective (1) to timely alert them to material information relating to NSTAR Electric's information required to be disclosed by NSTAR Electric in the reports that it files or submits under the Securities Exchange Act of 1934 and (2) to ensure that appropriate information is recorded, processed, summarized and reported within the time periods specified in the Secur ities and Exchange Commission's rules and forms.

There have been no changes in NSTAR Electric’s internal control over financial reporting (as defined in Rules 13a-15(f) or 15d-15(f) of the Securities Exchange Act of 1934) during NSTAR Electric's most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, NSTAR Electric's internal control over financial reporting.

Part II - Other Information

Item 1. Legal Proceedings

In the normal course of its business, NSTAR Electric and its subsidiaries are involved in certain legal matters, including civil litigation. Management is unable to fully determine a range of reasonably possible court-ordered damages, settlement amounts, and related litigation costs ("legal liabilities") that would be in excess of amounts accrued and amounts covered by insurance. Based on the information currently available, NSTAR Electric does not believe that it is probable that any such legal liability will have a material impact on its consolidated financial position. However, it is reasonably possible that additional legal liabilities that may result from changes in circumstances could have a material impact on its results of operations, financial condition, or cash flows.

Item 1A. Risk Factors

Investors or prospective investors should carefully consider the risk factors that were previously disclosed in NSTAR Electric's Annual Report on Form 10-K for the year ended December 31, 2009.
