Delmarva Power 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 Maryland Public Service
Commission. Under a settlement with the Commission, Delmarva Power began
offering SOS supply at market-based rates in Maryland on June 1, 2004.
Each year in June and
October, supply rates are adjusted to reflect the cost of power that Delmarva
Power buys on behalf of its customers who do not contract with an alternative
For Maryland small
commercial customers, the new summer SOS rate will decrease the average monthly bill by about $ 33.00
beginning June 1, 2014. The new winter
SOS rates for Maryland beginning October 1, 2014 have not yet been set.
