Best Electricity Rates in Delaware 2026
Delaware is one of the smaller deregulated electricity markets in the U.S., but it offers real savings for residents and small businesses willing to compare suppliers. Since the state opened its retail electricity market under the Electric Utility Restructuring Act, Delawareans have had the right to choose their electricity supplier — separate from the utility that physically delivers the power. In 2026, with rising standard offer service rates and dozens of competitive suppliers active in the state, switching can shave 10–25% off your monthly electric bill.
This guide breaks down how Delaware’s electricity market works, the current best rates by region, and exactly how to switch suppliers without any service interruption.

How Electricity Deregulation Works in Delaware
Delaware deregulated its electricity market in 1999, but unlike some Northeast states, the rollout has been gradual. Today, every residential and commercial customer in Delaware has the right to choose a competitive electricity supplier — formally called a Retail Electric Supplier (RES) — that supplies the actual electricity (the “supply” portion of your bill). Delmarva Power, the regulated utility serving most of the state, continues to deliver that electricity over its wires and handle billing, metering, and emergency repairs regardless of which supplier you choose.
That separation matters because it eliminates the most common objection to switching: there’s no risk of losing power, no new wiring, no second meter. The only thing that changes is the supplier line item on your monthly bill.
Delaware’s Standard Offer Service Rate (2026)
If you don’t choose a supplier, Delmarva Power assigns you the default Standard Offer Service (SOS) rate, which is procured through utility auctions and adjusted annually. As of mid-2026, the residential SOS rate sits around 11.4¢ per kWh — up roughly 8% year over year, driven by higher PJM capacity prices and rising natural gas costs in the mid-Atlantic.
Delaware’s competitive suppliers are currently offering 12-month fixed rates as low as 9.2–9.8¢ per kWh, which translates to $25–45 per month in savings for an average household using 900 kWh.
Best Electricity Suppliers in Delaware 2026
The Delaware Public Service Commission maintains a list of every licensed competitive supplier, but only a handful actively market to residential customers. The most active providers in 2026 include:
- Constellation — A subsidiary of Exelon and one of the largest competitive suppliers in the U.S. Offers 12-, 24-, and 36-month fixed rate plans with strong reliability and bilingual customer service. Frequently the lowest 24-month rate in Delaware.
- NRG / Reliant Energy — Offers fixed and variable plans, including 100% renewable energy options. Has been aggressive on Delaware pricing in 2026.
- Direct Energy — Owned by NRG since 2023, Direct Energy continues to operate as a separate brand in Delaware with month-to-month and 12-month fixed plans.
- Public Power LLC — A smaller East Coast supplier that often beats the big national brands on shorter-term contracts.
- Inspire Clean Energy — Subscription-based model (flat monthly fee instead of per-kWh) with 100% renewable energy. Best fit for high-usage homes.
How to Compare Delaware Electricity Plans
Three things matter when you compare a supplier offer against your current Standard Offer Service rate:
- The price per kWh — Compare apples to apples. Make sure you’re comparing the supplier’s all-in rate to Delmarva’s SOS rate, not to your total bill (which includes delivery, taxes, and surcharges that don’t change).
- The contract length — A 12-month fixed rate locks in your supply rate for a year. After it expires, you’ll either roll to a month-to-month rate (often higher) or need to switch again. Set a calendar reminder for 30 days before contract end.
- Cancellation fees — Most fixed-rate plans charge $50–150 if you cancel early. Variable plans typically don’t have cancellation fees but the rate can spike without warning.
Watch Out For: Variable Rate “Teaser” Plans
Several Delaware suppliers have been flagged by the state PSC for marketing introductory variable rates as low as 7¢/kWh that reset to 16–22¢/kWh after the first 1–3 months. Always read the terms and conditions, and prefer 12+ month fixed-rate contracts unless you actively monitor your bill every month.
How to Switch Electricity Suppliers in Delaware
The process is straightforward and takes about 5 minutes:
- Find your account number on a recent Delmarva Power bill (top right corner)
- Compare current offers using a comparison tool (we recommend the form above) or directly on the Delaware Public Service Commission’s supplier list
- Sign up online with your chosen supplier — you’ll need your name, address, and Delmarva account number
- Your switch takes effect on your next meter read (1–2 billing cycles)
- Continue paying your normal Delmarva bill — the supplier change appears as a different “supply” line item
You’ll never lose power during the switch, and you can switch back to Standard Offer Service at any time without penalty (though you may owe an early termination fee if you break a fixed-rate contract).
Frequently Asked Questions
Will switching electricity suppliers in Delaware affect my reliability?
No. Delmarva Power continues to own and maintain all the wires, transformers, and infrastructure regardless of which supplier you choose. Outage response, line repairs, and 24/7 emergency service all stay with Delmarva.
How much can I save by switching electricity suppliers in Delaware?
Most Delaware households save $25–45 per month by switching from Standard Offer Service to a competitive 12-month fixed-rate plan. Annual savings typically run $300–550 depending on usage.
Can I switch back to Delmarva if I don’t like my new supplier?
Yes. You can return to Delmarva’s Standard Offer Service at any time. If you’re under a fixed-rate contract you may owe an early termination fee (typically $50–150), but there’s no permanent commitment.
Do competitive suppliers in Delaware offer green energy?
Yes. Inspire Clean Energy, NRG, and Constellation all offer 100% renewable plans backed by Renewable Energy Certificates (RECs). Premium for green plans typically runs 0.5–1.5¢/kWh above standard rates.
What happens to my budget billing or autopay if I switch?
Both stay in place with Delmarva. The supplier switch only changes the supply portion of your bill — billing, autopay, paperless preferences, and budget billing all remain with Delmarva Power.
Is there a fee to switch electricity suppliers in Delaware?
No. Delaware does not charge a switching fee, and Delmarva Power does not charge a fee to enroll a new supplier on your account. The only fees come from suppliers themselves if you break a fixed-rate contract early.
Bottom Line: Delaware Electricity in 2026
With Standard Offer Service hovering above 11¢/kWh and competitive suppliers offering fixed rates as low as 9.2¢, Delaware residents who haven’t shopped their electricity in 12+ months are almost certainly overpaying. A 5-minute comparison and switch will lock in 10–25% savings for the next 12–24 months — and there’s zero risk to your service reliability.
