Delaware Electricity Information

Delaware offers retail electricity choice for most customers, so the utility delivers power while residents and businesses can select a third-party supplier for the supply portion of the bill. Customers served by Delmarva Power and Delaware Electric Cooperative are eligible to shop, and the Delaware Public Service Commission maintains an active list of licensed suppliers and consumer guidance. If you do not choose a supplier, the utility provides default supply service, and delivery remains with the utility either way. This market structure creates flexibility on price and product options while keeping reliability under regulated utility operations.

Delaware’s electricity generation is dominated by natural gas, which supplies the vast majority of the state’s power. While coal once played a larger role, it has mostly been phased out, and renewables like solar and offshore wind are gradually expanding. However, Delaware still imports much of its electricity from neighboring states.

Electricity consumption is moderate, but prices are slightly above the national average due to transmission costs and reliance on out-of-state power. The shift away from coal has helped reduce emissions, though natural gas remains a significant source of greenhouse gases. With growing investments in clean energy and efficiency, Delaware is working toward a greener and more resilient energy future.

Delaware’s electricity use follows a Mid-Atlantic climate with cold winters and warm, humid summers that push winter heating and summer cooling peaks. Residential customers are the largest slice of demand at about 46% of electricity sales in 2024, with commercial at ~38% and industrial at ~17%, which keeps household usage central to grid planning. The state sits in a transition zone between humid subtropical and humid continental climates, so coastal moderation reduces extremes but seasonal swings still drive pronounced peaks.

Delaware Natural Gas Information

Delaware’s reliance on natural gas has grown quickly over the past two decades as coal plants were retired or converted, making gas the backbone of electricity generation and an essential part of daily life. Cold Mid-Atlantic winters drive demand for home heating, while hot, humid summers push gas-fired plants to keep up with air-conditioning loads. With no in-state production, Delaware depends on interstate pipelines, so reliability and storage play a critical role in keeping both homes and the grid supplied.

About 42% of households in Delaware use natural gas as their primary heating source, while electricity and propane make up much of the rest. The industrial sector accounts for roughly 40% of all natural gas deliveries, and the residential sector about 13%. Most households are served by Chesapeake Utilities or Delmarva Power, which both purchase and deliver the fuel. This blend of local utility service and interstate pipeline reliance makes natural gas a cornerstone of Delaware’s energy system in every season.
