Supply Rates to Decrease for Pepco District of Columbia Customers

New Standard Offer Service rates Effective June 1

Bottom Line - The Cost of Electricity is Going Down

WASHINGTON - The District of Columbia Public Service (DCPSC) has authorized a decrease in supply rates. Based on the results of a competitive auction, District customers who buy their electricity through the Standard Offer Service (SOS) program will see decreases in their electricity bills beginning June 1, 2012. SOS represents about 70 percent of a residential customer's bill. The change will decrease average monthly residential electricity bills by about 5.8 percent. The average residential customer uses about 825 kWh per month in the summer and 615 kWh per month in the winter. The monthly bill for an average residential SOS customer will decrease by $5.25 adjusting the average bill from $90.00 to $84.74.

The supply cost of electricity (including generation and transmission) for SOS customers will decline from 9.75 cents per kWh in the summer to 8.86 cents per kWh and from 9.22 cents per kWh in the winter to 8.61 cents per kWh. As a result the supply portion of the average residential electricity bill will decline from $63.71 to $58.45. The average monthly residential bill (including supply and delivery charges) will be about $84.74.

"This is great news for our District of Columbia customers because the cost of electricity has the greatest impact on their bills," said Thomas H. Graham, President, Pepco Region.

The SOS program is administered by Pepco under rules established by the DCPSC. Under legislation passed by the D.C. Council in 1990, Pepco no longer owns any power plants. The DCPSC has designated Pepco to purchase electricity for SOS customers through power supply contracts in an annual auction.
