How Utility Service Is Organized in Delaware

Delaware is a small state with only three counties, but its utility map is a patchwork. Your electricity might come from Delmarva Power, a member-owned cooperative, or a city-run system. Your water might come from a private company, a town commission, or a municipal department. This page explains who runs what, so you can find the right office before you make a trip.

Most investor-owned utilities in the state answer to the Delaware Public Service Commission, based in Dover. The commission has five members appointed by the governor and works under Title 26 of the Delaware Code. It reviews rate requests, holds public hearings, and takes consumer complaints about electric, natural gas, water, and wastewater companies. A separate agency, the Division of the Public Advocate, speaks for ratepayers when rate cases come up.

Not every provider falls under that system. Electric cooperatives are governed by boards elected by their members. Municipal systems answer to city councils or utility boards. Water quality is a different track again. The Division of Public Health's Office of Drinking Water oversees public water systems, while the Department of Natural Resources and Environmental Control (DNREC) handles well permits and water supply planning. Our listing for the Water Resources Division at 89 Kings Highway Southwest in Dover sits on this state-agency side.

In practice, three questions decide where you go. Who delivers the service? Who sets the rates? Who handles complaints? The company name on your bill answers the first. The other two depend on whether that company is private, a cooperative, or a municipality.

Electric, Gas, and Fuel Providers Across Delaware's Three Counties

Delmarva Power & Light Co, listed at 1624 Jessup Street in Wilmington (302-652-1553), is the main investor-owned electric delivery company in the state. Delaware Electric Co-Op Inc, listed at 14198 Sussex Highway in Greenwood (302-349-9090), serves members in rural parts of Kent and Sussex. Several cities, including Dover, Newark, Smyrna, and Milford, run their own electric systems and bill customers directly. Check a recent bill to see whose name appears at the top.

Delaware's 1999 electric restructuring law separated power delivery from power supply. You still pay your local utility to deliver electricity, but many customers can buy the supply portion from a licensed competitive supplier. NRG Energy, listed at 29416 Road 332 in Dagsboro (302-934-3500), is one name in that market. Co-op and municipal customers may have different options, so ask your provider first.

For natural gas, Chesapeake Utilities has listings at 350 South Queen Street in Dover (302-734-6700) and 345 Reybold Road in Newark (302-266-8258). Eastern Shore Natural Gas appears twice in Dover, at 417 Bank Lane and 1110 Forrest Avenue (both 302-734-6720). That company is mainly a pipeline operator that moves gas to local distributors. For a new home hookup, start with the local distribution company instead.

Propane and heating oil work differently. Poore's Propane Gas Services (3799 North Dupont Highway, Dover), Sharp Energy Inc. Dover (5011 North Dupont Highway), Tri Gas & Oil Co Inc (20501 Dupont Boulevard, Georgetown), and Acorn Energy (3903 Centerville Road, Greenville) are private fuel dealers. Compare quotes, ask who owns the tank, and read any delivery contract before you sign.

Kent County: Dover Anchors Government and Utility Offices

Dover has 14 of the 45 listings in our database, more than any other city. It is the state capital, so state agencies and local providers sit close together. The City of Dover Utilities Department is at 860 Buttner Place (302-736-7070). Dover Water & Wastewater is at 15 Loockerman Plaza (302-736-7058). Tidewater Utilities, Inc. is at 1100 South Little Creek Road (302-734-7500).

Dover is unusual because the city itself supplies electricity, water, and wastewater service, so one municipal account can cover several services. Outside city limits, sewer service is generally handled by the county or a private water company, so confirm which applies to your street. Middlesex Water C., at 8 South Main Street in Smyrna (302-653-7849), is another Kent County listing. Browse the full set of Kent County utility offices to compare addresses and phone numbers.

Sussex County: Beach Towns, Inland Bays, and Co-op Territory

Sussex County is where the water map gets crowded. Dagsboro alone has five listings. They include Tidewater Utilities at 103 Riverview Drive (302-732-3014), Roseville Middlesex Water Company at 30524 Piney Neck Road (302-732-3950), and Water Systems Council at 305 Cea Dag Circle (302-732-3110).

Along the coast, Bethany Beach is served by both the Bethany Beach Water Department at 434 Collins Street (302-537-0851) and Sussex Shores Water Company at 39602 Waterworks Court (302-539-7611). Middlesex Water Company has an office at 17832 Coastal Highway in Lewes (302-645-8715). In the southwest corner, the Delmar Town Water Commission is at 100 North Pennsylvania Avenue (302-846-2664), and a Middlesex Water Co office is on Bacons Road (302-875-3808).

Sussex County Utility Billing, at 2 The Circle in Georgetown (302-855-7870), is the place to ask about county sewer charges. Summer crowds raise demand at the beaches, so ask about seasonal turn-on and shutoff when you rent or buy a second home. Our Sussex County utility listings cover each town.

New Castle County: Fewer Listings, Most of the Population

New Castle County has seven listings, but it holds more than half of the state's residents. Delmarva Power's Wilmington office, Chesapeake Utilities in Newark, and Acorn Energy in Greenville are the main entries. Large suburban providers rely heavily on online accounts and call centers, so a walk-in counter is less common here. Wilmington's water is handled through city public works, and Artesian Water Company is a major private supplier in the suburbs. Newark runs its own electric system. See the New Castle County utility offices for the addresses we have on file.

Practical Steps Before You Call or Visit a Delaware Utility Office

If you are struggling with a bill, ask your provider about payment plans first. Then ask about state energy assistance programs, which are run through Delaware's human services agencies.

Municipal utility departments throughout Delaware provide electricity, water, sewer, and related services to millions of residents and businesses. Utility governance in Delaware is shaped by the state's public utility commission, which regulates investor-owned utilities, while municipally owned systems operate under local authority.

Utilities locations are available in 17 cities across Delaware. They are spread across 3 counties.

Cities with the highest concentration of utility offices include Dover, Dagsboro, Wilmington, reflecting their larger populations and service area demands.

Delaware residents should contact their local utility provider directly for account setup, billing questions, and outage reporting. State-level utility assistance programs may also be available through the state's health and human services agency.

Seasonal Demand and Rural Gaps in Delaware Utility Service

Delaware's utility needs change with the calendar. In the Sussex County beach towns, summer visitors multiply water and sewer demand, and small systems such as those in Bethany Beach and Sussex Shores must plan for peak weeks. Rental owners should ask about seasonal accounts and final readings before closing a property for winter.

Storms are the other regular test. Nor'easters and tropical systems can knock out power across coastal areas and farm country. If the lights go out, report the outage to your electric provider, whether that is Delmarva Power, Delaware Electric Cooperative, or a city system. If you smell gas, leave the building and call 911, then call the gas company from outside.

Rural parts of Kent County and Sussex County often have no public water or sewer line at the road. Those homes use private wells, septic systems, and propane tanks. That means fewer bills to a utility, but more responsibility for testing, maintenance, and fuel deliveries.

Because the state is small, a short phone call usually saves a trip. Dover offices are an easy drive from most of Kent County, while Georgetown is the county seat for Sussex. Have your account number handy, and write down the name of anyone who gives you a commitment about a date or a charge.

Frequently Asked Questions About Utilities in Delaware

Start with the company's customer service and ask for a written explanation of the charge. If a private gas, electric, or water utility does not resolve it, contact the Delaware Public Service Commission in Dover, which takes complaints about regulated companies. Keep your account number, bills, and notes on who you spoke with and when. For an electric cooperative, raise the issue with member services and then the board. For a city-run system such as Dover's, ask for a supervisor and then the city council. Drinking-water quality concerns go to the state's Office of Drinking Water.

First identify the provider for your exact address, because service areas do not follow ZIP codes. Delmarva Power covers much of the state, Delaware Electric Cooperative serves rural parts of Kent and Sussex, and several cities run their own systems, including Dover. Our listings show Delmarva Power at 302-652-1553, the cooperative at 302-349-9090, and the City of Dover Utilities Department at 302-736-7070. Have photo ID, the service address, your move-in date, and lease or closing papers ready. Some providers ask for a deposit or credit check, so request service several days ahead.

Often yes. Delaware's 1999 restructuring law allows many customers to buy electricity supply from a licensed competitive supplier, while the local utility still delivers the power and handles outages. Your delivery company stays the same, and its charges still appear on your bill. Before you switch, compare whether the rate is fixed or variable, how long the contract runs, and what an early cancellation costs. Customers of cooperatives and municipal systems may have different rules, so ask your provider before signing anything. The Public Service Commission can confirm whether a supplier is licensed.

It depends on the street. In Bethany Beach, the town's Bethany Beach Water Department (302-537-0851) serves some properties, while Sussex Shores Water Company (302-539-7611) serves others nearby. Tidewater Utilities in Dagsboro (302-732-3014) and Middlesex Water Company in Lewes (302-645-8715) cover other communities. Sewer charges in county districts are billed through Sussex County Utility Billing in Georgetown (302-855-7870). Check a previous bill or ask the seller or landlord which company serves the address. Then ask about seasonal shutoff and turn-on if the property sits empty in winter.

Many rural homes in Kent and Sussex counties are not on public water or sewer. Well drilling requires a permit from DNREC, and septic systems also fall under state environmental rules, so check before building or repairing either. The state's drinking water program oversees public systems, not individual household wells. That means you are responsible for testing your own well water, and a local lab can advise which tests suit your area. Ask a licensed contractor to confirm what permits apply. Homes like these often also depend on propane, so compare delivery quotes from dealers such as those listed in Dover and Georgetown.

Call 811, the national call-before-you-dig number, which connects Delaware callers to Miss Utility of Delmarva. The service is free. Utility companies then mark their underground gas, electric, water, and communication lines. Make the call several working days before you plan to dig, and the operator will tell you the exact waiting period. Marks cover public utility lines only. Private lines, such as a sprinkler system, a lamp-post cable, or a line to a detached garage, are usually your responsibility to locate. Hitting a gas line is dangerous, so do not skip this step.
