Understanding Energy Choice in Wilmington
Delaware deregulated its electricity market in the late 1990s, allowing customers to choose their electricity supplier while the local utility continues to deliver power through its wires. In Wilmington, Delmarva Power handles delivery, meter reading, and outage response, but customers can purchase the electricity itself from licensed third-party suppliers. This creates opportunities to lock in fixed rates, choose renewable energy plans, or find better value.
Understanding the difference between supply and delivery is the first step toward smarter energy decisions. Below are ten energy suppliers and providers that serve the Wilmington area.

How to Compare Energy Suppliers
Start by reviewing your current bill to find your supply rate, measured in cents per kilowatt-hour. Compare this rate with offers from suppliers, paying close attention to contract length, early termination fees, and whether the rate is fixed or variable. Variable rates may start low but can rise sharply during periods of high demand. The Delaware Public Service Commission provides resources to help consumers understand their options.
Businesses should consider working with a supplier that offers custom procurement strategies, demand response programs, and detailed usage analytics.
Benefits of Choosing the Right Supplier
The right supplier can provide price stability, renewable energy options, and better customer service. Fixed-rate plans protect households from market volatility, while green energy plans support wind and solar development. For businesses, strategic energy procurement can significantly reduce operating costs.
Energy Market Trends
Electricity prices across the PJM region have risen due to growing demand from data centers, electrification, and capacity market changes. As a result, more customers are seeking fixed-rate contracts and efficiency upgrades. Smart meters and time-of-use rates are giving customers new ways to save by shifting usage to off-peak hours.
Frequently Asked Questions
Will switching suppliers affect my power reliability?
No. Delmarva Power continues to deliver your electricity, maintain the lines, and respond to outages regardless of which supplier you choose. Only the generation source and supply price change.
How do I switch electricity suppliers?
Choose a licensed supplier, review the contract terms, and enroll using your Delmarva Power account number. The switch typically takes effect within one or two billing cycles, and your bill will show both supply and delivery charges.
Are green energy plans more expensive?
Some renewable plans cost slightly more, but competitive offers sometimes match or beat standard rates. Look for plans backed by recognized renewable energy certificates to ensure your purchase supports clean generation.
What is a teaser rate?
A teaser rate is a low introductory price that converts to a higher variable rate after a short period. Always read the terms to understand what happens when the introductory period ends, and set a reminder before your contract expires.
Can businesses negotiate custom energy contracts?
Yes. Larger commercial and industrial customers can work with suppliers or energy brokers to secure custom pricing, blend fixed and market-indexed rates, and participate in demand response programs that pay them to reduce usage during peak periods.
