What Businesses in This Region Are Actually Paying
If you run a business in Pennsylvania, New Jersey, or Delaware, your electricity cost has two stories: the one on the rate sheet and the one on your bill. The rate sheet shows a per-kWh price. The bill shows what that price becomes after delivery charges, riders, and, for many commercial accounts, demand charges that can quietly outweigh the energy itself.
The regional context first. All-in electricity costs across the area track the territory you operate in: roughly the 19 to 21 cent range across much of Pennsylvania and Delaware, and 26 cents and up in parts of New Jersey, with commercial rate classes paying lower energy rates than residential but layering demand charges on top. Every one of those numbers has moved sharply upward since 2024, and the forces behind the increase have not finished working through the system.
This page explains how commercial pricing is actually built in our three states, what your options are in the deregulated market, where supplier shopping helps and where it hits a ceiling, and the one decision that changes a facility’s cost basis rather than rearranging its margin.

The Anatomy of a Commercial Electric Bill
Commercial bills in this region break into three layers, and understanding them is prerequisite to reducing any of them.
Supply (generation)
The cost of the electricity itself, billed per kWh. This is the competitive layer: in all three states, you can buy it from your utility’s default service or from a licensed third-party supplier. It is also the layer that has absorbed the brunt of the PJM-driven increases.
Delivery (distribution and transmission)
The regulated layer: poles, wires, transformers, and the crews that maintain them, billed by your local utility regardless of who supplies your energy. PECO, PPL, PSE&G, JCP&L, ACE, Delmarva, and the rest each set delivery rates through rate cases before their state commissions. You cannot shop this layer. You can only reduce how much of it you buy.
Demand charges
The layer that surprises every business owner the first time they see it explained. Beyond billing your total consumption (kWh), commercial rate classes bill your peak rate of draw (kW): the highest short-interval demand your facility hit during the billing period.
The logic: the grid must be built to serve your peak, not your average. The consequence: a facility that idles at modest draw but spikes hard, compressors starting simultaneously, an electric oven bank firing at opening, machinery cycling at shift start, pays for that spike across the entire month. For large commercial customers, demand charges commonly run 30 to 70 percent of the total bill.
This is why two businesses with identical monthly kWh can receive wildly different bills, and why “what is your rate per kWh” is an incomplete question for any serious commercial account.
Deregulation: How Supplier Choice Works Here
Pennsylvania, New Jersey, and Delaware all restructured their electricity markets in the late 1990s, separating generation (competitive) from delivery (regulated monopoly). The practical result for businesses: you may choose who supplies your energy, while your utility keeps delivering it either way.
Pennsylvania
PA opened retail choice under the Electricity Generation Customer Choice and Competition Act. Businesses that do not shop receive default service priced at the utility’s price to compare, which resets quarterly for most rate classes. The state runs PAPowerSwitch as the official comparison platform. Commercial shopping is common, and supplier offers are benchmarked against the PTC.
New Jersey
NJ restructured under the Electric Discount and Energy Competition Act of 1999. The default is Basic Generation Service, procured through the state’s annual BGS auction, which is why NJ default rates step rather than drift: each February’s auction certifies the next year’s reality. NJPowerSwitch is the official shopping platform. The 2025 auction cycle, absorbing the PJM capacity surge, pushed BGS rates up roughly 17 to 20 percent across the four utilities, which is precisely the kind of reset that sends businesses shopping.
Delaware
Delaware restructured in 1999 as well. Delmarva Power commercial customers can choose a supplier, with non-shoppers receiving standard offer service. Delaware Electric Cooperative and municipal utility customers generally do not have retail choice. The shopping market is thinner than PA or NJ but real for Delmarva commercial accounts.
Third-Party Suppliers: Where They Help and Where They Cannot
A third-party supplier (TPS) competes against your utility’s default rate. The honest case for shopping: when default rates reset upward, as BGS did, a supplier locking a fixed rate below the new default delivers genuine savings, and fixed-term contracts buy budgeting certainty that quarterly-resetting default service does not.
The honest limits, which the comparison sites are less eager to explain:
Every supplier buys from the same market. PJM wholesale costs, including the capacity surge, reach every contract. A supplier can time the market and shave margin; it cannot make the underlying power cheaper.
The contract is the product. Commercial supply agreements carry structures that deserve scrutiny: teaser fixed periods rolling into variable rates, bandwidth clauses that reprice you if usage deviates from projections, pass-through provisions that forward capacity and transmission cost increases mid-contract (making your “fixed” rate fixed in name), and auto-renewal terms that quietly roll you into month-to-month pricing at the contract’s end.
Demand charges survive shopping. Supplier contracts address the supply layer. Delivery and demand charges, for many facilities the majority of the bill, are untouched by switching.
The discipline for any TPS quote: confirm what is actually fixed, what passes through, what happens at term end, and what the rate becomes if your usage shifts. Then benchmark against the default rate’s known reset schedule rather than against last year’s bill.
Why Rates Are Rising and Staying Risen
The driver is structural, and it is the same one hitting residential customers. PJM, the grid operator for all three states, runs an annual capacity auction securing future supply commitments. Recent auctions cleared more than 800 percent above prior levels, propelled by data center demand growth, accelerating plant retirements, and an interconnection queue too backlogged to bring replacement supply online quickly. The July 2025 auction (for the 2026/2027 delivery year) cleared at its price cap, and the trend did not break: the December 2025 auction (2027/2028) cleared at a record cap for the third consecutive auction. The next auction, for the 2028/2029 delivery year, is scheduled for June 2026 and currently has no price cap in place, which a coalition of state governors has asked PJM to reinstate.
Those capacity costs flow into BGS auction results in New Jersey, price-to-compare resets in Pennsylvania, standard offer service in Delaware, and every TPS contract written against the same wholesale reality. PJM itself has signaled that the supply-demand imbalance is a multi-year condition. Businesses budgeting for electricity should plan for elevated rates as the baseline, not the anomaly.
For many businesses, reducing consumption is no longer enough. Investing in commercial solar services can help stabilize long-term electricity costs while reducing exposure to future utility rate increases.

The Ceiling on Shopping, and the Lever Beyond It
Here is the strategic picture once the mechanics are clear. Supplier shopping, done carefully, optimizes your position within the market: it shaves margin, times resets, and buys term certainty. What it cannot do is change your exposure to the market, because every contract ultimately prices the same rising wholesale reality, and the delivery and demand layers never enter the competition at all.
One lever operates differently. On-site solar generation changes the quantity of grid electricity a facility buys rather than the price paid per unit. Energy produced on your roof is supply you do not purchase from anyone, at a cost fixed on installation day and immune to every future auction, reset, and pass-through. For facilities with meaningful daytime load, it can also flatten the consumption profile that drives demand charges, attacking the bill layer no supplier contract reaches.
The commercial tax treatment makes 2026 specifically relevant: the Section 48E Investment Tax Credit remains available at 30 percent for systems beginning construction by July 4, 2026, with MACRS accelerated depreciation layered on top. Those mechanics, and how solar performs across warehouses, manufacturing, offices, and retail, are covered in depth here.

Shopping optimizes the variable cost. Generation converts it to a fixed one. Most sophisticated commercial energy strategies in this region now involve both.

Business Electricity Rate FAQs
What is the average business electricity rate in PA, NJ, and DE?
Commercial rates vary widely by rate class, usage profile, and demand characteristics, but all-in costs across the region generally track the same utilities driving residential rates: roughly 19 to 21 cents per kWh territory in much of Pennsylvania and Delaware, and 26 cents or higher in parts of New Jersey. Larger commercial accounts pay lower per-kWh energy rates but add demand charges, which can represent 30 to 70 percent of the total bill for high-demand facilities.
What are demand charges on a commercial electric bill?
Demand charges bill a business for its highest rate of electricity draw during the billing period, measured in kilowatts over short intervals, separately from total consumption. A facility that briefly spikes to a high draw pays for that peak all month. For large commercial customers, demand charges commonly account for 30 to 70 percent of the bill, which is why two businesses using identical kWh can pay very different totals.
Can businesses choose their electricity supplier in PA, NJ, and DE?
Yes. All three states deregulated electricity generation in the late 1990s. Businesses can buy supply from a licensed third-party supplier while the local utility continues delivering power and maintaining lines. Businesses that do not choose a supplier receive default service: the price to compare in Pennsylvania, Basic Generation Service in New Jersey, and standard offer service in Delaware.
Is a third-party energy supplier cheaper than the utility?
Sometimes, and the gap is usually modest. Suppliers compete against the utility default rate and can offer fixed terms that beat it, particularly when default rates reset upward. But supplier contracts carry their own risks: variable rates after teaser periods, bandwidth clauses, pass-through provisions for capacity costs, and auto-renewal terms. Every supplier is buying from the same PJM wholesale market, which caps how much shopping alone can save.
Why are commercial electricity rates rising in the region?
The dominant driver is the PJM capacity market, where prices surged over 800 percent at recent auctions due to data center demand growth, power plant retirements, and a backlogged interconnection queue. Those capacity costs flow into both default service rates and supplier contracts across PA, NJ, and DE. These are structural conditions expected to keep rates elevated for years.
