About electricity rates in Maryland
Maryland is a restructured state with retail choice. Baltimore Gas and Electric, Pepco, Delmarva Power and Potomac Edison own the delivery wires, and their customers may buy generation from a competitive supplier or stay on standard offer service that the utility procures. The Southern Maryland Electric Cooperative and Choptank Electric Cooperative serve southern Maryland and the Eastern Shore. The Maryland Public Service Commission regulates the utilities and licenses suppliers.
Maryland imports a large share of its electricity through the PJM regional grid, and in-state generation is led by the Calvert Cliffs nuclear plant and natural gas, with most coal plants now retired and solar growing. Hot, humid summers bring heavy air-conditioning use, and winters are cold enough that homes rely on a mix of gas, electric and oil heating. Net metering is available, and a community solar program lets households subscribe to shared projects.
