Transmission Rate Incentives Requested for Maine Power Connection

Market Wire, July, 2008

Officials at Maine Public Service Company (MPS), a subsidiary of Maine & Maritimes Corporation (AMEX: MAM), and Central Maine Power Company (CMP) submitted a joint petition to the Federal Energy Regulatory Commission (FERC) on July 18, 2008, requesting authorization for transmission rate incentives in connection with the Maine Power Connection Project (MPC Project). The MPC Project, with an estimated cost of $625 million, consists of a proposed 200-mile, 345 kV transmission line and the construction of new and upgraded substations. Together, CMP and MPS are developing this voluntary market efficiency project that will provide significant benefits to regional markets and also provide electrical reliability benefits to Maine and New England.

The request for rate incentives was made pursuant to the Federal Power Act, Section 219 and FERC Order No. 679 which allow incentive rates to promote investment in transmission projects providing significant competition, market enhancement, and reliability benefits. MPS and CMP requested that FERC issue a decision by September 18, 2008. Pending Federal and State approvals, the companies expect project construction to begin in June, 2009. In the filing, MPS and CMP requested formula rate-based incentives to recover revenue requirements for the MPC Project, including: (1) an additional return on equity (ROE) of 150 basis points above each company's base ROE and (2) recovery of prudently incurred costs if the MPC Project is abandoned.
