We are 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
supply cost by about $ 33.00 beginning June 1, 2014. Also, in October when the
new winter SOS rates take effect in Maryland, the average monthly supply cost
will decrease by about $16.00. Combined, the new summer and winter supply rates
will decrease supply costs by about $22.00.
