Oil and Gas in the Wilmington Region
The Delaware River has been one of America's most important energy corridors for more than a century. Refineries, terminals, and pipelines along the river serve the Northeast's dense population, and Wilmington sits right in the middle of this network. While Delaware is actively pursuing clean energy, oil and natural gas still power transportation, heating, manufacturing, and electricity generation across the region.
From large-scale refining to local heating oil delivery, the following ten companies play key roles in supplying energy to Wilmington homes and businesses.

Why the Oil and Gas Sector Matters Locally
The oil and gas industry supports thousands of jobs in refining, pipeline operations, logistics, and home services. It also provides tax revenue and supports related industries such as chemical manufacturing, which depends on hydrocarbon feedstocks. For many Wilmington households, natural gas and heating oil remain the primary sources of winter warmth.
Industry Trends
The sector is adapting to a changing energy landscape. Refiners are investing in renewable diesel and lower-carbon fuels, while utilities are upgrading aging pipelines to reduce leaks and improve safety. Heating oil companies increasingly offer bioheat blends and high-efficiency heat pump installations. Delaware's climate goals are encouraging electrification, but natural gas continues to play a role in grid reliability as renewable capacity grows.
Choosing an Energy Provider
For homeowners, compare pricing plans such as budget billing, fixed-price contracts, and automatic delivery. Look for companies with strong safety records, responsive emergency service, and maintenance programs. Businesses should consider fleet fueling programs and long-term supply agreements that provide price stability.
Frequently Asked Questions
Is natural gas available throughout Wilmington?
Natural gas service is widely available in the city and much of northern New Castle County through Delmarva Power. Some rural or older properties may rely on heating oil or propane instead.
What is bioheat?
Bioheat is heating oil blended with renewable biodiesel. It burns cleaner than traditional heating oil and can typically be used in existing furnaces and boilers without modification.
How can I save on heating oil costs?
Options include budget payment plans, pre-buy or fixed-price contracts, automatic delivery, and annual furnace maintenance to keep equipment running efficiently. Improving home insulation also reduces fuel use.
Should I switch from oil heat to a heat pump?
Modern cold-climate heat pumps perform well in Delaware winters and can lower energy costs and emissions. Many homeowners keep their existing system as a backup during the coldest days. Rebates through Delaware efficiency programs may help offset the cost of installation.
Why do gasoline prices change so often in the region?
Fuel prices reflect global crude oil markets, refinery output, seasonal fuel blends, transportation costs, and taxes. Because the Delaware City Refinery and regional terminals supply much of the area, planned maintenance or unexpected outages can also influence local prices.
