How Power Plant Services Work Across Maryland

Maryland has no single power plant office where a resident can walk in and get an answer. Electricity here is handled by a chain of owners, grid operators, regulators and local governments. This page lists generating stations, cogeneration units, solar arrays, landfill-gas plants and related facilities across Maryland, so you can find the one you need and work out who actually answers for it.

That distinction matters because most plants are private industrial sites. A gas-fired station in Brandywine or a wind project near Oakland has a control room and a corporate owner, not a public counter. Your practical contact is usually the owner's community line, your electric utility, or a state regulator.

Who Regulates Generating Stations in Maryland

The Maryland Public Service Commission (PSC) is the main state regulator. It sits at 6 St. Paul Street in Baltimore. Under the Public Utilities Article of the state code, a company generally needs a Certificate of Public Convenience and Necessity from the PSC before it builds a generating station above roughly 2 megawatts. Smaller projects usually go through local zoning and building permits instead.

Several other agencies share the work. The Maryland Department of Natural Resources runs the Power Plant Research Program, which studies the environmental and natural-resource effects of proposed plants and advises the PSC. The Maryland Department of the Environment issues air, water-discharge and waste permits. The Maryland Energy Administration handles energy policy, efficiency programs and many clean-energy incentives.

Wholesale power moves across a regional grid run by PJM Interconnection, a multi-state operator. Maryland plants sell into PJM's markets, and PJM decides which units run to keep the lights on. The state does not dispatch individual plants, so a plant down the road from you may be serving customers in another state.

Utilities, Deregulation and What It Means at Your Door

Maryland restructured its electric industry under the Electric Customer Choice and Competition Act of 1999. Since then, companies such as BGE, Pepco, Delmarva Power and Potomac Edison have delivered electricity over their wires. Power generation is a competitive business. A plant in your county does not necessarily supply your home.

Some areas follow a different model. Southern Maryland Electric Cooperative and Choptank Electric Cooperative serve many rural customers. Municipal systems, including Easton Utilities on the Eastern Shore, run their own distribution. Knowing which one you are connected to saves time when you call.

Here is who to contact for the most common problems:

Maryland's Metro Corridor Versus Its Rural Counties

The listings cluster where people and heavy industry cluster. Baltimore County has the most entries. They include Back River Waste Water Treatment on Eastern Avenue, Eastern Landfill Gas on Days Cove Road in White Marsh, Riverside on Sollers Point Road in Dundalk, and a senior-living campus plant in Glen Arm. Many metro entries turn waste into energy, using sewage gas, landfill gas or on-site combined heat and power.

Along the Baltimore-Washington corridor, larger fossil plants sit near rivers, rail and transmission lines. The Herbert A. Wagner station on Brandon Shores Road in Curtis Bay is part of an Anne Arundel County cluster that PJM has leaned on for regional reliability. Prince George's County lists the Brandywine Power Facility, the NRG Chalk Point site in Aquasco, a county-run plant on Brown Station Road in Upper Marlboro, and the University of Maryland's combined heat and power plant in College Park. In Montgomery County, the NIH Cogeneration Facility in Bethesda and the Dickerson station anchor the list.

Rural Maryland looks different. Frederick, Hagerstown and Emmitsburg show solar arrays, including Fort Detrick Solar PV and the Emmitsburg Solar Arrays. On the Eastern Shore, Easton, Church Hill and Berlin have smaller local plants and solar. In Cumberland, the AES Warrior Run cogeneration facility reflects Western Maryland's coal history. In Southern Maryland, Lusby is home to the Cove Point LNG terminal, and the Calvert Cliffs nuclear station is also nearby. Western Maryland's ridgelines host wind turbines, such as the Criterion project on Eagle Rock Road in Oakland, in Garrett County.

Where Solar and Wind Are Growing

State policy is pushing the mix toward renewables. The Clean Energy Jobs Act of 2019 raised Maryland's renewable portfolio standard to 50 percent by 2030. Utility-scale solar now competes with farmland, so siting fights often land at county hearings. For larger projects the PSC holds a public hearing, usually in the affected county, where residents can speak or file written comments.

If a project is proposed near you, find its PSC case number and read the filings. They list the acreage, the equipment, the setbacks and the conditions the applicant has agreed to. Those documents are public and free to read online.

Practical Steps Before You Contact a Maryland Power Plant

A little preparation gets a faster answer. Most plants do not take walk-in visitors, because they are secured industrial sites with safety rules. Call first, state your purpose, and expect to be routed to a plant manager or a corporate affairs contact.

Before you call, gather these details:

Plant tours are possible for schools and community groups at some sites, but the owner decides, and security approvals can take weeks. Permit files and inspection records can be requested from state agencies under the Maryland Public Information Act. Most offices answer during weekday business hours, while public hearings are often held in the evening. If a number on a listing is missing or out of date, start with the owner's main line or the county government office.

Power plant facilities in Maryland include a mix of federal, state, and municipally owned generation assets that contribute to the region's overall electricity supply. Maryland'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 76 cities across Maryland. They are spread across 21 counties.

Areas with the highest concentration of power plant locations include Baltimore, Hagerstown, Easton, often reflecting proximity to water resources, fuel supply infrastructure, or industrial demand centers.

Residents of Maryland 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.

Residents of Maryland 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 Maryland, contacting the state's public utility commission is often the best starting point.

Reading the Maryland Power Plant Listings Like a Local

Many listing names are shorthand, and decoding them helps you search faster. "Apg Combined Heat And Power Plant" in Edgewood refers to Aberdeen Proving Ground in Harford County. "Umcp Chp Plant" is the University of Maryland, College Park's combined heat and power plant. "Nih Cogeneration Facility" serves the National Institutes of Health campus in Bethesda. "Lfge" in the Montgomery County Oaks entry stands for landfill gas to energy.

Entries on the Eastern Shore tend to be small and local. The Easton 2 listing on Glebe Park Drive in Talbot County shows the phone number 410-822-6110. Gateway Solar on Old Ocean City Road in Berlin sits in Worcester County, the county nearest the proposed offshore wind areas. In Hagerstown, the ESS Fairgrounds entry on Security Road reminds you that a listing can be a modest on-site installation rather than a large station.

Always confirm the current status before you plan a visit or file a complaint. Plants change owners, switch fuels and retire units. Check the listing's county, then match it to the utility that serves that area.

The Maryland Public Service Commission decides whether a larger generating station gets a Certificate of Public Convenience and Necessity. The Department of Natural Resources' Power Plant Research Program reviews environmental effects and advises the Commission. The Maryland Department of the Environment handles air and water permits. The county still controls zoning and local building approvals. Public hearings are normally held in the county affected, and anyone can file written comments in the case. The docket is public, so you can read the application, the conditions and the staff recommendations before you speak.

Call your electric utility, not the plant. Generating stations feed the regional grid, while BGE, Pepco, Delmarva Power, Potomac Edison, a cooperative such as SMECO or Choptank, or a municipal system such as Easton Utilities maintains the lines to your home. Your bill shows which company serves you. Report the outage through its outage line or app. If you see a downed wire, a fire or a gas smell, stay back and call 911 first. Calling the plant only delays help because its staff cannot restore neighborhood service.

Sometimes, but not on a walk-in basis. Plants are secured industrial sites, and visits depend on the owner's policy, current safety conditions and staff availability. Schools, civic groups and professional associations have the best chance. Contact the owner's community or corporate affairs office several weeks ahead, name your group size and purpose, and be ready to supply identification. Some owners also run visitor programs or open houses at other times. A solar array or wind site can often be seen from public roads without entering, and that is usually the simplest option.

Those sites generate power from waste byproducts. Landfills produce methane, which can run engines or turbines. Wastewater plants, such as Back River Waste Water Treatment in the Baltimore area, can capture biogas from sewage treatment. Entries such as Eastern Landfill Gas in White Marsh and the Montgomery County Oaks plant near Gaithersburg fit this pattern. Their main job is waste management, with electricity as a secondary product. For questions about odor, truck traffic or permits, the operator and the Maryland Department of the Environment are more relevant than the electric utility.

Status changes more often than directories do. Several large coal units in Maryland, including those at Chalk Point and Dickerson, have retired in recent years, and other sites have changed fuel or ownership. Start by calling the owner's main line. You can also search the Public Service Commission's case files, look up permits through the Maryland Department of the Environment, or check PJM's public generator information. If the listing has a phone number, try it first. If it does not, contact the county government office for the area.

The Maryland Energy Assistance Program helps eligible households with heating and electric costs. You apply through the local administering agency in your county, often a community action agency or the local social services office. Bring proof of income, a recent utility bill, identification and Social Security numbers for household members. Your utility can also explain payment plans and shutoff rules. If you cannot settle a billing problem with the company, you can file a complaint with the Public Service Commission. Acting before the account is far behind gives you more options.
