Commercial electricity costs are climbing in Summer 2026, putting additional pressure on operating budgets. Extreme heat is pushing electricity demand higher while utilities and grid operators face rising capacity costs, supply constraints, and growing demand from large energy users.

For businesses, however, higher electricity costs aren’t just about paying more for each kilowatt-hour (kWh). A commercial electric bill can also be affected by when electricity is used and how much power a facility requires at one time.

Understanding those differences is critical to understanding why commercial electricity bills are rising and what businesses can do about it.

Key Takeaways

Summer 2026 is combining higher utility electricity prices with intense demand on the electric grid. Businesses can’t control utility rates or wholesale energy markets, but they can better understand their bills and manage some of the factors that drive costs.

What should businesses know about rising electricity costs?

• Electricity usage charges are based on the amount of electricity a facility consumes.
• Commercial demand charges can be based on the facility’s highest electricity demand during a defined interval.
• Peak-hour electricity pricing can make electricity more expensive during high-demand periods.
• Reducing peak loads and improving energy efficiency can help businesses manage electricity costs.
• Utility incentives and rebates can offset the cost of qualifying energy efficiency improvements.

What Are Usage Charges, Demand Charges, and Peak Hour Pricing?

Before looking at why electricity prices are rising, it’s important to understand three different ways electricity can affect a commercial utility bill.

Electricity usage charges are based on how much electricity a facility consumes, measured in kilowatt-hours (kWh). If the per-kWh rate increases or a building consumes more electricity, this portion of the bill rises.

Demand charges are different. Commercial demand charges are generally based on the highest level of electricity a facility draws during a defined measurement interval, often 15 minutes. Demand is measured in kilowatts (kW). One period when HVAC, refrigeration, equipment, lighting, and other major loads operate simultaneously can establish a facility’s peak demand and significantly affect its bill.

Peak-hour electricity pricing refers to rate structures in which electricity costs more during periods of high grid demand. Depending on the utility and tariff, a business may encounter time-of-use rates, demand charges, or both.

Put simply: usage measures how much electricity you consume, demand measures how much power you need at once, and peak pricing considers when you consume it.

Understanding all three helps explain why two facilities that consume similar amounts of electricity can receive very different electric bills.

Why Are Commercial Electricity Costs Increasing in 2026?

Several forces are pushing utility electricity costs higher in 2026.

Within the PJM Interconnection region, which serves all or parts of 13 states and Washington, D.C., electricity demand continues to grow while the grid faces increasing capacity needs. PJM’s 2026/2027 capacity auction cleared at $329.17/MW-day, compared with $269.92/MW-day for most of the region in the previous auction.

Businesses are also seeing changes at the utility level. In PECO territory, for example, commercial generation charges increased by 15% on June 1.

Then came the summer heat.

On July 2, PJM reported an instantaneous peak of approximately 162,700 MW before accounting for demand-response resources, potentially surpassing a system record that had stood since 2006.

These events create a difficult combination for commercial customers: a higher underlying cost of electricity at the same time facilities are using more power for cooling.

Why Does Summer Make Demand Charges More Important?

Imagine a commercial facility at 3 p.m. on a hot July afternoon.

Air-conditioning systems are working at full capacity. Lights are on. Refrigeration, manufacturing equipment, computers, EV chargers, and other electrical loads may all be operating.

Even if that extreme load lasts only briefly, it can create a high-demand peak for the billing period, depending on the applicable utility tariff.

That means businesses should look beyond total monthly consumption. Knowing when a building reaches its highest demand can reveal opportunities to control costs.

How Can Businesses Reduce Demand Charges?

Businesses can’t control utility rate increases, but they can manage how their facilities use electricity.

• Identify peak demand. Review bills and interval data to determine when each facility reaches its highest electrical load.
• Stagger large loads. When operations allow, avoid running multiple energy-intensive systems simultaneously.
• Optimize HVAC. Scheduling, controls, maintenance, and high-efficiency equipment can reduce cooling demand.
• Use building controls. Automated controls can adjust equipment schedules and help prevent unnecessary demand spikes.
• Improve energy efficiency. LED lighting, HVAC upgrades, motors, refrigeration, and controls can reduce overall electricity consumption and potentially lower peak demand.
• Evaluate utility incentives. Rebates and incentives can reduce the upfront cost of qualifying efficiency improvements.

Can Utility Incentives Help Offset Rising Electricity Costs?

Energy efficiency becomes more financially valuable as electricity costs rise. The challenge is often paying for the improvements needed to capture those savings.

Utility incentive and rebate programs can help.

Depending on the utility, location, and program, upgrades involving LED lighting, HVAC, building controls, refrigeration, motors, and other energy-efficient technologies may qualify for financial incentives.

For multi-site businesses, managing these opportunities can quickly become complicated. Programs vary by utility, and each may have different eligibility requirements, deadlines, documentation, and application processes.

Incentive Rebate360 provides fully turn-key incentive and rebate management, helping businesses identify available programs, qualify projects, manage applications, and collect incentives. That can lower project costs and help organizations move forward with efficiency improvements that reduce their exposure to rising utility costs.

Frequently Asked Questions

How Can I Tell if Demand Charges Are a Significant Part of My Electric Bill?

Review the demand, kW, or billed demand line items on your commercial utility bill and compare them with your energy charges. The terminology and calculation method vary by utility and rate class, so reviewing your specific tariff can help clarify how much peak demand contributes to your total cost.

Do All Commercial Businesses Pay Demand Charges?

No. Demand charges depend on the utility, rate schedule, service territory, and sometimes the size or type of account. Some commercial customers pay primarily for energy consumption, while others have rate structures that include demand or time-based pricing.

Which Energy Efficiency Projects May Qualify for Utility Rebates?

Available incentives vary by utility, but commercial programs may provide rebates for qualifying LED lighting, HVAC, building controls, refrigeration, motors, and other energy efficiency improvements. Incentive Rebate360 can identify available programs and manage the rebate process across different utility territories.

Take Control of the Costs You Can

Summer 2026 is highlighting a larger shift in commercial electricity costs. Businesses are facing higher utility prices while extreme temperatures and growing grid demand increase the importance of how and when facilities consume electricity.

Not every part of the electric bill is within your control. Utility rates, capacity prices, and extreme weather aren’t.

Your facility’s energy strategy is.

Understanding usage, demand, and peak pricing can help you identify where costs originate and where efficiency investments can have the greatest impact. When those improvements qualify for utility incentives, Incentive Rebate360 can help secure available funding and strengthen the financial case for action.
