Delmarva Power wants to reduce rates for its Maryland customers. The utility company filing plans to cut rates by about $3.82 per residential electric customer. If approved, the reductions would go into effect in March. However, the reductions may not be readily apparent, as they will mainly offset a rate increase approved by the Maryland Public Service Commission last month. Last week, Delmarva Power announced Delaware ratepayers will see a decrease in their monthly bills between $3 – $4.60.
