Why Is My PECO Electric Bill So High in 2026?

If your PECO electric bill feels unusually high in 2026, the first question is not simply:

Pennsylvania electric bills have multiple moving pieces.

Your total can change because of:

• Electricity supply
• PJM capacity and transmission costs
• PECO delivery charges
• Your choice of electricity supplier
• Weather
• Household electricity usage
• HVAC efficiency

That means the right diagnosis starts by separating what electricity costs from how much electricity your home is using.

PECO Delivers Electricity — but You Can Choose the Supplier

Pennsylvania has electric choice.

PECO maintains the local poles, wires and distribution system.

But homeowners may purchase the generation portion of their electricity from PECO default service or from a competitive electric generation supplier.

Pennsylvania's official PA Power Switch program makes the distinction clear: the distribution company delivers the electricity; the supplier sells it.

That means a high PECO bill can sometimes be partly a supplier problem, not only a PECO problem.

Step 1: Find Your Electricity Supplier

Look at your current bill.

Identify:

• Supplier name
• Generation rate
• Fixed or variable pricing
• Contract expiration date
• Cancellation fee
• PECO Price to Compare

If you switched suppliers several years ago and have not reviewed the contract recently, start there.

A promotional rate can expire.

A fixed contract can become variable.

And a rate that was attractive when you signed up may no longer be competitive.

What Is the Price to Compare?

The Price to Compare is PECO's default supply price. Pennsylvania customers can use it as the benchmark when comparing competitive electricity suppliers.

If a supplier charges less than PECO's current Price to Compare under comparable terms, it may offer supply savings.

If it charges substantially more, understand what you are receiving in exchange — renewable content, longer-term price protection or other contract features.

PECO Rates Include More Than Generation

PECO's residential tariff also contains charges related to distribution, transmission, generation supply, and riders and adjustments.

PECO's current 2026 electric tariff reflects rate changes effective January 1, 2026.

So comparing only the advertised generation rate does not tell you what the entire bill should be.

Why Is PJM Showing Up in Pennsylvania Electricity Discussions?

PECO operates inside the PJM Interconnection regional electricity market.

PJM coordinates the bulk power system across Pennsylvania and numerous neighboring states.

That means electricity costs can be affected by regional factors such as:

• Power-plant availability
• Generation retirements
• Transmission constraints
• Capacity markets
• Large new electricity loads

This is why something happening outside Philadelphia can eventually influence electricity-market conditions affecting PECO customers.

Are Data Centers Part of the Problem?

Data centers are now one of the biggest new sources of electricity demand in PJM.

In June 2026, PJM said explicitly that the primary driver of current electricity-demand growth is data centers.

PJM also said new data centers can be developed roughly two to three times faster than many new generation resources needed to supply them.

Demand is growing fast, while new power plants come online slowly. That mismatch has helped tighten supply and push capacity prices higher.

Did Data Centers Cause My High PECO Electric Bill?

Not necessarily.

That would be too simplistic.

A high PECO bill may reflect your electricity supplier, current PECO tariffs, PJM market costs, weather, household usage or HVAC.

Data centers are increasingly part of the regional cost environment.

They are not an explanation for every line item on your personal bill.

Household Usage Can Still Overwhelm a Rate Change

Suppose July 2025 was 850 kWh and July 2026 was 1,300 kWh.

Your usage increased by more than 50%.

Even if electricity prices stayed exactly the same, your bill would rise dramatically.

That is why comparing dollars without comparing kWh can be misleading.

Why Might Philadelphia-Area Summer Usage Increase?

Common causes include:

• Central air conditioning
• Heat pumps
• Dehumidifiers
• Older HVAC
• Poor attic insulation
• Leaky ductwork
• More people home during the day
• Pool equipment
• EV charging

Hot, humid weather can dramatically increase cooling runtime.

Winter Usage Can Be Expensive Too

Electric usage can rise during colder Pennsylvania weather because of heat pumps, electric resistance backup heat, space heaters, electric water heating and furnace blowers.

If your thermostat frequently shows AUX HEAT, your heating system may be using electric resistance heat.

That can consume substantially more electricity.

Step 2: Compare the Same Month Year Over Year

Compare August 2025 with August 2026 — not May with August.

Look at total kWh, number of billing days, weather and household changes.

If the bill increased 25% but usage increased 30%, the explanation may be mostly inside the home.

Step 3: Evaluate HVAC

Look for longer runtime, uneven temperatures, weak airflow, high humidity, frequent repairs, increasing annual kWh and older equipment.

The question is not whether your HVAC works.

Step 4: Evaluate Insulation and Air Leakage

Pennsylvania's four-season climate punishes inefficient homes.

Heat escapes in winter. Heat and humidity enter in summer.

Look at attic insulation, basement rim joists, windows, doors, ductwork and air leakage.

Reducing the home's energy requirement can improve economics regardless of what future PJM prices do.

Step 5: Review Your Supplier Contract

Before spending thousands of dollars on home-energy equipment, check whether you are simply paying an unnecessarily expensive supply rate.

Visit Pennsylvania's official electric-shopping marketplace and compare your current terms with available offers.

Pay attention to fixed versus variable rate, term length, cancellation fees, introductory pricing and renewable content.

A supplier change may be one of the easiest energy decisions available.

Step 6: Reduce Household Demand

Suppose your home currently uses 14,000 kWh per year.

HVAC and efficiency improvements reduce that to 11,000 kWh.

That removes 3,000 kWh of annual electricity purchases.

You are now less exposed to supplier pricing, PJM capacity costs, transmission and future rate increases.

Step 7: Evaluate Solar

Pennsylvania allows qualifying residential solar systems to participate in net metering.

Solar may reduce the amount of electricity you purchase from the grid.

Pennsylvania also has an SREC market, which can create additional value for qualifying generation.

But any 2026 calculation should use current rules.

The former federal residential clean-energy tax credit is no longer available for expenditures after December 31, 2025.

Do not let an outdated 30% federal-credit assumption determine your project's economics.

Step 8: Evaluate Battery Storage

Battery storage can help maintain critical loads during outages.

Those might include the refrigerator, sump pump, well pump, internet, furnace controls and medical equipment.

Its primary value may be resilience rather than monthly bill reduction.

Should You Install Solar Because Your PECO Bill Is High?

Not automatically.

Use this sequence:

1. Identify your supplier.
2. Compare your supply rate.
3. Review kWh.
4. Evaluate HVAC.
5. Evaluate insulation.
6. Understand PECO and PJM costs.
7. Then evaluate solar and battery.

The most expensive answer is not always the correct answer.
