Maryland
Standard Offer Service
Overview – Delmarva Power uses a competitive bidding process to buy electricity for customers who do not choose a Third Party Supplier (TPS). Customers are charged for this service—called Standard Offer Service (SOS)—under rates approved by the Maryland Public Service Commission to permit recovery of Delmarva's cost of purchasing power at competitive wholesale market prices. Customers who do not choose to switch to a TPS, or who leave a TPS to return to their Electric Delivery Company, are supplied with Standard Offer Service (SOS).
SOS is the default electric supply service provided by Delmarva Power.
