Where Delaware rates are today
Delaware’s electricity rates are moderate compared to many other deregulated states. With an average residential price around 18.12¢ per kilowatt-hour (September 2025), they sit just below the U.S. average. Customers have the option to choose their supplier, but because Delaware participates in the PJM wholesale market and imports much of its power, supply rates are primarily driven by regional wholesale prices rather than strictly in-state
Why Delaware rates have been the way they are
Delaware is part of the PJM interconnection, so wholesale power prices largely determine what retail suppliers pay for energy. Natural gas remains the primary fuel for electricity generation in the mid-Atlantic, so swings in gas prices feed directly into supply costs. Transmission upgrades, renewable-energy program costs, and regional capacity charges also add to the bill. On the other hand, a competitive retail market and moderate local demand help keep average prices from reaching the highs seen in New England or downstate New York.ors.
Where Delaware rates are going in the next 3 months
Looking ahead to winter 2025–26, most analysts expect modest upward pressure on Delaware’s electricity supply costs. National wholesale power and natural-gas prices have been trending higher, and regional demand typically rises during cold weather. That said, any increases are likely to be gradual – on the order of 1–3 percent over the next three months – barring an extreme cold snap that drives up gas and power markets. Customers who monitor the market may still find competitive fixed-rate offers that hedge against winter volatility.
Key takeaway for businesses
For commercial and small-business customers in Delaware, the competitive retail market provides an opportunity to manage energy budgets proactively. With wholesale prices gently trending upward heading into winter, it often makes sense to shop around now and lock in a fixed-rate plan before demand peaks. Staying on top of offers from multiple suppliers, and taking advantage of multi-month or multi-year contracts when the forward market is calm, can protect against price spikes later in the season.
