• Standard Offer Service

  • We buy electricity for customers who have not chosen to purchase electricity from a certified competitive electric provider. Called the Standard Offer Service (SOS) program, this program is approved by the Delaware Public Service Commission. 

    Each year in June (for the summer) and in October (for the winter), generation rates from the SOS program are adjusted to reflect the cost of power that Delmarva buys on behalf of its customers.
