District of Columbia SOS
What Is Standard Offer Service?
Pepco is required to buy electricity for customers who do not choose an alternative electricity supplier. Customers are charged for electricity – called Standard Offer Service (SOS) – under rates approved by the District of Columbia Public Service Commission. Under a settlement with the Commission, Pepco began offering SOS supply at market-based rates in the District of Columbia on February 8, 2005.
Each year in June supply rates are adjusted to reflect the cost of power that Pepco buys on behalf of its customers who do not contract with an alternative supplier.
For District residential customers, the new summer SOS rate will add about $3.49 to the average monthly bill. In October, when the new winter SOS rate takes effect in D.C., the average monthly bill of a District residential customer will increase by $2.12.
Combined, the new winter and summer supply rates for the District will increase the annual average monthly bill by $2.69. For an average District customer who uses about 730 kWh of electricity a month this would result in an increase of 2.7 percent.
