Mays Landing, N.J. - Atlantic City Electric filed today with the New Jersey Board of Public Utilities for permission to reset two billing components. The utility is asking for a decrease to the Net Generation Charge (NGC) and an increase to the Societal Benefits Charge (SBC) to be collected from all customers for the period of October 1, 2007, through September 30, 2008.

The net impact of the proposed adjustments will provide an overall rate decrease of approximately $131.8 million. The estimated savings for an average residential customer using approximately 1,000 kWh per month is about $12.87 or 8.57% on a total monthly bill.

The proposed changes to the rates are based on a true up of deferred actual and estimated costs and revenues collected through the current NGC and SBC rates as of September 30, 2007, and forecasted costs and revenues for the period October 1, 2007, through September 30, 2008.

The purpose of the NGC and SBC rate components is to recover, on an unbundled basis, certain utility costs and expenses. The NGC provides primarily for recovery of the above-market component of payments made under a utility's Non-Utility Generation (NUG) contracts and stranded costs associated with such commitments. The SBC is intended to permit utilities to recover costs related to:

· Universal Service Fund and Lifeline social programs

· Clean Energy Program

· Uncollectible Accounts

· Consumer Education

In this filing, the increase to the SBC is due to the increased costs associated with funding the New Jersey Clean Energy Program, which is administered statewide by the Board of Public Utilities' Office of Clean Energy, through 2008. The final amount of any adjustment to customer rates as proposed by the Atlantic City Electric is subject to review and approval of the New Jersey Board of Public Utilities.
