Delaware is a small state with a surprisingly varied electricity system. Our directory lists 39 power plant sites across its three counties, from a coastal wind turbine in Lewes to a refinery power plant in Delaware City. This page explains who regulates these facilities, how they differ from north to south, and how to use the listings to find the right site or the right agency.
Not every listing is a traditional generating station. Many are solar farms, landfill gas projects, combined heat and power units at factories, or small municipal plants. Knowing which type you are looking at tells you who to call.
Who Oversees Power Plants in Delaware
Delaware has no single office that runs every power plant. Responsibility is split among several bodies, and the right one depends on your question.
- Delaware Public Service Commission (Dover): sets rules for regulated utilities such as Delmarva Power and handles unresolved customer complaints about service and billing.
- DNREC, the Department of Natural Resources and Environmental Control: issues air quality and other environmental permits for generating units and runs state energy and climate programs.
- Municipal electric utilities: cities such as Dover, Newark, New Castle, Milford, Seaford, Smyrna and Lewes operate their own systems under local governance.
- Delaware Electric Cooperative: a member-owned utility that serves much of rural Kent and Sussex counties.
Behind all of them sits PJM Interconnection, the regional grid operator. Delaware lies within the PJM footprint, and plants here sell electricity into that wholesale market. PJM dispatches power according to price and system need, so a plant's output on a given day is not a local decision.
The state's renewable portfolio standard also shapes the map. It requires electricity suppliers to buy a growing share of their power from renewable sources. That policy helps explain why so many listings are solar farms and landfill gas projects rather than large fossil stations.
What Kinds of Power Plants Appear in Delaware Listings
The word power plant covers a wide range of equipment in this state. Reading the name and address usually reveals the type.
- Gas-fired and conventional stations: Garrison Energy Center in Dover and the Calpine Christiana plant in Wilmington are examples of this category.
- Solar arrays: Dover Sun Park, Milford Solar Farm and the Bruce A Henry Solar Farm turn open land into generating capacity.
- Wind: the University of Delaware turbine at Lewes is a rare utility-scale wind installation in the state.
- Landfill gas and waste-related projects: Ameresco sites in Georgetown and Felton, plus solar at a Kent County wastewater facility, reuse resources a community already produces.
- Industrial combined heat and power: Croda Atlas Point in New Castle and the Delaware City Refinery Power Plant supply factories directly.
North to South: How Power Plants Differ Across Delaware's Counties
Each of Delaware's three counties has its own energy profile. Geography, industry and population density shape what you will find.
New Castle County: Industry and Dense Demand
The northern county has the most listings and the heaviest industrial load. In Wilmington, the Calpine Mid-Atlantic Generation Christiana plant sits on Christina Avenue. Farther south along the Delaware River, the Delaware City Refinery Power Plant on Wrangle Hill Road and the Delaware City Plant in Bear support heavy industry. Croda Atlas Point CHP on Cherry Lane in New Castle produces electricity and useful heat from the same fuel. Even a college-town suburb has local generation, as the Brookside listing on East Chestnut Hill Road in Newark shows. For locality-level detail, see the New Castle County page.
Kent County: Dover's Municipal Cluster
Kent County revolves around Dover, the state capital, which has its own city-run electric utility. Dover's listings include McKee Run on Buttner Place, Van Sant Station on Electric Avenue, Garrison Energy Center on Garrison Oak Drive, NRG Energy Center Dover on West North Street and Dover Sun Park on White Oak Road. In Smyrna, the DEMEC Warren F. Beasley Power Station on Artisan Drive is tied to the municipal joint-action group. An Ameresco project on Willow Grove Road in Felton rounds out the county. Browse the Kent County listings to compare them.
Sussex County: Coast, Farms and the Indian River
Sussex is the largest county by area and the most rural. The best-known site is the Indian River Generating Station at 29416 Road 332 in Dagsboro, which has a long history as one of the state's major generating sites. The poultry industry appears in the data too: Perdue Bridgeville Photovoltaic on Adams Road and Onyx Allen Harim in Harbeson show food processors generating power on site. Georgetown has Ameresco Delaware South on Landfill Lane and the Bruce A Henry Solar Farm on East Trap Pond Road. In Lewes, look for the University of Delaware wind turbine on Pilottown Road and Ess Lewes on Schley Avenue. Milford straddles the Kent-Sussex line, so always check the county shown in each listing. The full set is on the Sussex County page.
Finding the Right Delaware Power Plant Listing
Start with your question. If you want to know where a plant is, who operates it or what it produces, a listing page is the right place. If you have a billing problem or an outage, the plant itself is not the office to contact.
Before you call or visit, run through this short checklist:
- Identify the facility type: utility station, solar farm, landfill gas unit or factory plant.
- Note the operator in the name, such as Calpine, NRG, Ameresco or Croda.
- Check the county, because it determines which planning and zoning office has jurisdiction.
- Use the street address for map lookups only; many sites are fenced and secured.
- Where no phone number is listed, contact the operating utility rather than guessing.
Most power plants are secured industrial sites with no walk-in counter. Any tour or visit has to be arranged in advance with the operator. Public roads usually give a clear view of the larger sites.
Permits, Zoning and Public Input in Delaware
Building or changing a plant in Delaware involves several layers of review. DNREC examines air emissions, wastewater discharges and other environmental matters. County planning and zoning offices decide land use, and municipal planning departments do the same inside city limits. The Delaware Coastal Zone Act, passed in 1971, limits new heavy industry along the shoreline. That matters for sites near the Delaware River and Bay.
Residents can take part in this process. DNREC publishes public notices for permit applications and holds hearings on some of them, with comment periods announced in advance. Local land-use hearings are posted by the county or city involved, so watch those notices as well.
If a nearby plant raises a concern about noise, odor or visible smoke, begin with the operator. Then contact DNREC if the problem continues. Keep dates, times and photographs, because specific records make a complaint much easier to act on.
Power plant facilities in Delaware include a mix of federal, state, and municipally owned generation assets that contribute to the region's overall electricity supply. Delaware's energy mix and the number of publicly owned facilities reflect the state's natural resources, regulatory environment, and historical development of its utility infrastructure.
Power Plant locations are available in 15 cities across Delaware. They are spread across 3 counties.
Areas with the highest concentration of power plant locations include Wilmington, Dover, Smyrna, often reflecting proximity to water resources, fuel supply infrastructure, or industrial demand centers.
Residents of Delaware who are customers of a municipal or public power utility can contact their local power authority for billing assistance, energy efficiency programs, and information about planned outages or infrastructure upgrades in their service area.
Power Plant by Counties
Residents of Delaware who receive electricity service from a publicly owned utility can visit or contact that utility's customer service office to learn about outage reporting, billing options, and energy assistance programs. For information about a specific power generation facility in Delaware, contacting the state's public utility commission is often the best starting point.

Using Delaware Power Plant Listings in Practice
Delaware is compact, at roughly 96 miles from top to bottom. The whole state shares one utility regulator, the Public Service Commission, and one environmental agency, DNREC. That makes cross-checking a listing far easier than in a large state with dozens of overlapping authorities.
Watch for listings that share an address. The University of Delaware wind turbine and the facility on Parcel 3-35-4-131CR both sit at 700 Pilottown Road in Lewes, so they are likely parts of one site. The Kent County Sewage Treatment Plant and the Kent County Wastewater Treatment Solar listing both use 139 Milford Neck Road in Milford.
Some names, such as Delaware City 10 or Seaford, are database labels rather than formal facility names. Confirm the operator before you rely on one for research, a permit question or a vendor inquiry. In an emergency such as fire or a downed line, call 911 first.
