Exhibit 99.2
Report of Independent Registered Public Accounting Firm
To The Shareholder and Directors of NSTAR Electric Company:
In our opinion, the consolidated financial statements listed in the index appearing under Item 9.01 of this Form 8-K present fairly, in all material respects, the financial position of NSTAR Electric Company and its subsidiaries (the "Company") at December 31, 2006 and 2005, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2006 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 9.01 of this Form 8-K presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. These financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and finan cial statement schedule based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
As discussed in Note I to the accompanying consolidated financial statements, effective December 31, 2006, the Company adopted Statement of Financial Accounting Standards No. 158,Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans - an amendment of FASB Statements No. 87, 88, 106, and 132(R).
