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, we
began offering SOS supply at market-based rates in Maryland on June 1,
Each year in June and
October, supply rates are adjusted to reflect the cost of power that we buy on
behalf of our customers who do not contract with an alternative supplier.
For Maryland residential customers, the new summer SOS rate will increase
the average monthly summer bill by about $3.00 beginning June 1, 2016. Also, in October when the new
winter SOS rates effect in Maryland, the average monthly bill will decrease by about $9.00. Combined, the new summer and winter supply rates for Maryland will decrease the annual average monthly bill by about $7.00. For an average Maryland residential customer who uses about 1000 kilowatt-hour of electricity a month, this would result in a decrease of about 5.0 percent.
