About electricity rates in Delaware

Delaware allows retail choice: customers of Delmarva Power, the investor-owned utility that serves Wilmington and most of the state, may pick a competitive supplier for their generation while Delmarva continues to deliver it. Much of Kent and Sussex counties is served instead by the Delaware Electric Cooperative, and several towns, including Dover and Newark, run their own municipal utilities. The Delaware Public Service Commission regulates Delmarva's rates.

The state sits inside the PJM regional grid and generates relatively little of its own power, importing much of it from neighboring states; in-state plants run mainly on natural gas. Hot, humid summers make air-conditioning the main seasonal load, and winters are moderate. Net metering is available, rooftop and community solar have grown, and a renewable portfolio standard requires suppliers to source a rising share of their power from renewables.
