Exhibit 34.1

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholder of

Monongahela Power Company

We have examined Monongahela Power Company’s (the “Company’s”) compliance with the servicing criteria set forth in Item 1122(d) of the Securities and Exchange Commission’s Regulation AB for the environmental control property-backed securities transactions, the Senior Secured Sinking Fund Environmental Control Bonds, Series A and Series B, for which the Asserting Party acted as servicer (the “Platform”) described in the accompanying Management’s Report on Assessment of Compliance with SEC Regulation AB Servicing Criteria as of and for the year ended December 31, 2009 (the “Reporting Period”), excluding criteria 1122(d)(1)(ii), (1)(iii), (1)(iv), (2)(vi), (4)(ii), (4)(iii), (4)(v), (4)(ix), (4)(xi), (4)(xii), (4)(xiii), and (4)(xv), which management has determined are not applicable to the activities performed by the Company with respect to the Platform. Management is responsible for the Company’s compliance with the servicing criteria. Our responsibility is to express an opinion on the Company’s compliance with the servicing criteria based on our examination.

Our examination was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants, as adopted by the Public Company Accounting Oversight Board (United States), and, accordingly, included examining, on a test basis, evidence about the Company’s compliance with the applicable servicing criteria, including tests on a sample basis of the servicing activities related to the Platform, determining whether the Company performed those selected activities in compliance with the servicing criteria during the specified period, and performing such other procedures as we considered necessary in the circumstances. Our procedures were limited to selected servicing activities performed by the Company during the period covered by this report and, accordingly, such samples may not have included servicing activities related to each transaction included in the Platform. Further, an examination is not designed to detect noncompliance arising from errors that may have occurred prior to the period specified above that may have affected the balances or amounts calculated or reported by the Company during the period covered by this report. We believe that our examination provides a reasonable basis for our opinion. Our examination does not provide a legal determination on the Company’s compliance with the servicing criteria.

Our examination disclosed the following material noncompliance with 1122(d)(4)(xiv) applicable to the Company during the year ended December 31, 2009. The Company charged-off customer accounts in a time frame other than the time frame specified in the transaction agreement for the Reporting Period.

In our opinion, except for the material noncompliance described in the preceding paragraph, the Company complied, in all material respects, with the aforementioned applicable servicing criteria for the Platform as of and for the year ended December 31, 2009.
