How Ohio's 2025 PJM Base Residual Auction Results Will Directly Raise Your Commercial Electric Bill in 2026

Business type: General Commercial

If you run a business in Ohio and you haven't heard about the 2025 PJM Base Residual Auction results yet, brace yourself. What happened in that auction isn't abstract energy market news — it's the direct cause of an electricity cost increase that is already working its way into commercial electric bills across the state. Understanding what occurred, and more importantly what to do about it, could save your business thousands of dollars annually.

The 2025 PJM Base Residual Auction results have set the stage for elevated capacity prices that will ripple through every commercial electricity contract renewed or originated in 2026. Whether you're a manufacturing plant in Dayton, a medical office in Columbus, or a logistics hub in Cleveland, this auction affects you. In this guide, we break down exactly what the PJM capacity auction is, what the 2025 results mean in dollar terms, and — most importantly — what proactive strategies can protect your Ohio business from absorbing the full brunt of rising commercial electricity rates in 2026.

What Is the 2025 PJM Base Residual Auction and Why Ohio Business Owners Can't Afford to Ignore It

The Mechanics of the PJM Capacity Market

PJM Interconnection operates the electrical grid serving Ohio and 12 other states, covering roughly 65 million people and one of the world's largest electricity markets. To keep the lights on reliably, PJM doesn't just buy electricity in real time — it buys future capacity: the guarantee that enough power plants will be available to meet peak demand three years from now.

This forward procurement happens through the Base Residual Auction (BRA). Each year, PJM runs an auction in which power generators bid to provide capacity — essentially promising to be available to generate power during high-demand periods for a specific future delivery year. The auction clearing price sets what all suppliers and utilities must pay per megawatt-day to fulfill their capacity obligations.

Those capacity costs don't stay in the wholesale market. They flow directly into the electricity rates paid by every commercial customer in PJM's territory — including every business in Ohio.

What Happened in the 2025 BRA

The 2025 PJM Base Residual Auction, which set capacity prices for the 2026/2027 delivery year, produced results that continued the alarming trend established by the record-breaking 2024 auction. Following a historical low of roughly $28/MW-day in earlier years, the 2024 auction shocked the market with prices exceeding $270/MW-day. The 2025 auction confirmed this is not a one-cycle anomaly — it is a structural market shift.

Several forces are keeping capacity prices elevated:

Generation retirements outpacing new supply. More than 40 GW of aging coal and nuclear generation is expected to retire across PJM between 2024 and 2030 according to PJM's own resource adequacy studies. New renewables and gas plants are not entering the market fast enough to replace that capacity on a one-for-one reliability basis.

Explosive data center demand. Ohio has become one of the top data center markets in North America. Large AI infrastructure buildouts are driving demand growth projections upward with each successive PJM forecast update, requiring more capacity to be procured in every auction cycle.

Interconnection queue bottlenecks. New power projects face years of delays entering PJM's interconnection queue. Until FERC's Order 2023 interconnection reforms fully take effect, the supply pipeline remains constrained even as demand grows.

The result: Ohio business owners face Ohio commercial electricity rates in 2026 that are materially higher than anything experienced in the prior decade — driven primarily by capacity cost components embedded in their supply contracts.

How the 2025 PJM Auction Results Translate Into Higher Commercial Electric Bills Across Ohio in 2026

The Three-Year Lag: Why You're Paying for Decisions Made Years Ago

PJM's forward capacity market is designed around a three-year procurement horizon. The capacity procured in the 2025 auction covers the 2028/2029 delivery year — meaning the most immediate bill impact in 2026 flows from the 2023 auction (already delivered) and the landmark 2024 auction (now in its delivery year starting June 2025).

For 2026 commercial electricity bills, the pain points are:

Contracts renewing in 2026 will be priced at current market rates, which embed high capacity costs across the entire contract term
Month-to-month and variable-rate customers are experiencing elevated rates as capacity costs flow through immediately
Customers on fixed-price contracts signed before 2024 will face significant sticker shock at renewal — their supplier has been absorbing capacity costs above their locked-in rate

How Capacity Costs Appear on Your Bill

Capacity cost exposure varies by contract structure. Here's what Ohio commercial customers need to understand about their specific situation:

All-in Fixed Rate (pre-2024 contract): Your current rate was set before the capacity price surge. You're protected until renewal — but be prepared for a rate increase of 15-40%+ when your contract expires, depending on your usage profile and current market conditions.

All-in Fixed Rate (2025/2026 contract): Current market rates reflect elevated capacity pricing. You're paying the new "normal," but you're protected from further increases for your contract term.

Pass-Through/Cost-Plus Contract: Capacity costs are explicitly passed through to you as a line item or rate adjustment. You're feeling every dollar of the capacity price increase in real time.

Default Utility Service (SSO): Ohio utilities are implementing capacity cost adjustments through rate riders and tariff updates. If you're on Columbia Gas Electric, AEP Ohio, or FirstEnergy standard service offers, expect structured rate increases in 2026.

The Contract Renewal Cliff

Ohio energy market analysts describe a looming "renewal cliff" — the period in 2026 when a large volume of commercial contracts that were signed during 2022-2023 at historically low prices will come up for renewal. Businesses in this category should not wait until their contract expires to assess the market. By then, your negotiating window has narrowed significantly.

As detailed in our guide on commercial energy procurement timing strategy, the optimal time to begin a competitive procurement process is 6-12 months before your contract expiration — not 30 days before.

The Real Dollar Impact: How Much More Will Your Ohio Business Pay for Electricity After the PJM Capacity Price Surge

Building a Capacity Cost Calculation

Your annual capacity cost is determined by three variables:

Your Peak Load Contribution (PLC) in kilowatts — your share of PJM's system peak
The applicable capacity clearing price in $/MW-day
The 365-day delivery period

Formula: Annual Capacity Cost = (PLC in kW ÷ 1,000) × Capacity Price ($/MW-day) × 365

At historical low capacity prices ($28/MW-day), the costs were manageable. At post-2024 auction prices (~$270/MW-day or higher), the mathematics are entirely different:

Business Type	Estimated PLC	Old Annual Capacity Cost	New Annual Capacity Cost	Annual Increase
Small retail shop	40 kW	$409	$3,942	+$3,533
Restaurant/bar	80 kW	$818	$7,884	+$7,066
Medical office	200 kW	$2,044	$19,710	+$17,666
Light manufacturer	500 kW	$5,110	$49,275	+$44,165
Distribution center	1,500 kW	$15,330	$147,825	+$132,495
Large industrial	5,000 kW	$51,100	$492,750	+$441,650

These increases represent the capacity cost component alone — before energy (commodity), transmission, and distribution costs are factored in. For many Ohio commercial customers, capacity now represents 20-30% of their total electricity bill, up from 5-8% just a few years ago.

What This Means for Budget Planning

The magnitude of these numbers demands a deliberate response in your financial planning. Energy costs are no longer a predictable, stable line item — they are a volatile, materially significant operating expense that requires the same rigorous management as labor or materials.

For businesses that haven't revisited their commercial electricity contracts recently, a professional commercial energy audit is an essential first step to understanding your actual capacity exposure and identifying cost reduction opportunities.

Act Before Rates Hit: Proven Strategies Ohio Business Owners Can Use Right Now to Lock In Lower Commercial Energy Rates

The good news: Ohio's deregulated electricity market gives commercial businesses tools that customers in regulated states simply don't have. You have the legal right to choose your electricity supplier, negotiate your rate structure, and implement strategies to reduce your capacity cost basis. Here's how.

Strategy 1: Competitive Fixed-Rate Procurement — Act Now, Not at Renewal

The single highest-impact action most Ohio businesses can take is running a competitive fixed-rate procurement — engaging an independent energy broker to solicit bids from multiple licensed Ohio electricity suppliers simultaneously.

A well-executed competitive procurement:

Solicits pricing from 8-15+ competing suppliers
Enables apples-to-apples comparison of fixed-rate offers
Locks in your supply rate for 24-36 months, protecting you from future capacity price increases
Typically yields 10-25% savings versus default utility rates

The critical timing element: don't wait until your contract is about to expire. The market is most favorable when you have flexibility to walk away from any single offer. Begin your procurement process 6-12 months before expiration. If you're currently on a month-to-month or variable rate, start immediately.

Strategy 2: PLC Management — Reduce Your Capacity Tag

Your PLC is determined by your electricity consumption during PJM's 5 Coincident Peak (5-CP) hours — the five highest-demand hours on the entire PJM grid each summer. Reducing your consumption during just those five hours directly reduces your PLC for the following delivery year.

Effective PLC management tactics include:

Subscribing to 5-CP alert services that notify you when PJM peak events are likely
Pre-cooling building spaces before an anticipated peak so you can raise your HVAC setpoint during the peak event
Shifting energy-intensive processes (manufacturing, food processing, data operations) away from the 3-6 PM window on hot summer days
Installing automated demand response systems that execute curtailment plans without requiring manual intervention

A 15% PLC reduction at current capacity prices saves approximately $2,700-$66,000/year depending on your business size. For high-load operations, this is among the highest-ROI investments available.

Strategy 3: Demand Response Enrollment

Ohio businesses that can commit to controlled load reduction during grid stress events can earn payments from demand response programs while simultaneously lowering their PLC. As we've outlined in our demand response guide for Ohio businesses, demand response participants earn both direct revenue and indirect capacity cost reductions — a powerful double benefit at current market prices.

Strategy 4: Evaluate Battery Energy Storage

For businesses with PLCs above 200 kW, battery energy storage systems (BESS) merit serious financial evaluation. BESS can charge from the grid during off-peak hours and discharge during 5-CP events, effectively reducing your metered demand during the moments that determine your PLC. The federal Investment Tax Credit (30%+ for qualifying storage projects) substantially improves project economics.

Strategy 5: Contract Structure Optimization

If you're renewing an existing contract or entering a new one, the structure matters as much as the rate. Work with your energy advisor to understand the difference between:

Fixed capacity pricing (capacity cost locked into your rate for the contract term)
Capacity pass-through (you absorb future PJM auction results — higher risk)
Index-plus pricing (a combination that may suit some risk tolerances)

In the current high-capacity environment, fixed capacity structures are generally preferred. See our comprehensive fixed vs. variable rate guide for a detailed comparison.

Conclusion: Proactivity Is the Only Effective Strategy

The 2025 PJM Base Residual Auction results are not a future risk — they are a present reality being priced into every commercial electricity contract in Ohio right now. Businesses that wait for their renewal notice to start thinking about energy procurement are already behind.

The Ohio commercial energy market offers genuine opportunities for businesses that act proactively: competitive supplier pricing, PLC management, demand response revenue, and strategic contract structures. But these opportunities require lead time to execute properly. The businesses that recognize the urgency of the current market conditions and begin competitive procurement processes in Q2-Q3 2026 will lock in rates that their competitors — who wait for their renewal date — will envy for the next two to three years.

Key takeaways:

The 2025 PJM BRA has set capacity prices at historically elevated levels that flow directly into 2026 Ohio commercial electricity rates
The renewal cliff is real — contracts signed at pre-2024 prices are expiring now, and renewal rates will be materially higher
Ohio's deregulated market gives you tools — competitive procurement, PLC management, demand response — that regulated-state businesses can't access
Act 6-12 months before your contract expiration for maximum market leverage

Frequently Asked Questions: 2025 PJM Auction Results and Ohio Commercial Electricity

Q: What exactly is the 2025 PJM Base Residual Auction? A: The PJM Base Residual Auction is an annual competitive auction run by PJM Interconnection, the grid operator serving Ohio and 12 other states, to procure "capacity" — essentially reservations of power generation — for a specific future delivery year. The 2025 auction sets prices for the 2028/2029 delivery year, while the 2024 auction (which set record prices) is currently in its 2025/2026 delivery period, directly affecting Ohio commercial electricity bills right now.

Q: Why are Ohio commercial electricity rates rising in 2026 specifically? A: 2026 is when a large cohort of commercial electricity contracts signed at historically low 2022-2023 rates are expiring. These customers are now entering the renewal market and encountering rates that reflect the 800%+ capacity price increase from the landmark 2024 PJM auction, as well as ongoing supply/demand imbalances in the PJM market.

Q: How much will my Ohio business electricity bill increase in 2026? A: The increase depends heavily on your business size, current PLC, current contract structure, and whether you're on a fixed-rate or variable-rate contract. As a rough guideline, businesses renewing from pre-2024 fixed-rate contracts can expect 15-40%+ rate increases at renewal. Businesses already on variable or pass-through contracts are experiencing increases now.

Q: Can I lock in rates before my current contract expires? A: Yes, in most cases. Ohio's deregulated market allows businesses to switch suppliers at any time, and many contracts can be renewed early. However, early termination fees may apply to your existing contract. An energy broker can help you evaluate whether early switching makes financial sense given current market rates versus your remaining contract term.

Q: What is a Peak Load Contribution (PLC) and why does it matter? A: Your PLC is your share of PJM's peak electricity demand, measured in kilowatts. It's calculated based on your actual electricity consumption during the five highest-demand hours on the PJM grid each summer (the 5-CP events). Your PLC directly determines your annual capacity charges — reducing it through curtailment during 5-CP events is one of the most effective ways to reduce your electricity costs.

Q: How do I find the capacity charges on my Ohio commercial electric bill? A: On competitive supplier invoices, look for line items labeled "Capacity Charge," "ICAP," "PJM Capacity," or "Reliability." On all-in fixed-rate contracts, the capacity cost is bundled into your per-kWh rate with no separate line item. Ask your supplier for a cost component breakdown to understand your full capacity exposure.

Q: Will PJM capacity prices ever come back down? A: Market consensus suggests some moderation is possible in the 2027-2028 timeframe as PJM's interconnection queue reform enables more new generation to come online. However, the retirement of aging thermal generation and continued data center demand growth create ongoing upward pressure. Capacity prices are unlikely to return to pre-2024 historical lows in any near-term scenario.

Q: Is it worth hiring an energy broker to handle my commercial procurement? A: For most Ohio commercial businesses, yes. An independent broker's market access and competitive bid process typically yields savings that far exceed any fees. The key is ensuring your broker is independent — not captive to specific suppliers — so they can run a genuinely competitive process on your behalf.
