Electricity rates are rising in Pennsylvania, and homeowners are paying noticeably more for power in 2026. This guide explains how much rates went up, what is driving the increase, and what you can still control.
Pennsylvania's average home electricity price through June 2026 was 20.90¢ per kWh (kilowatt-hour, the unit on your bill). It was 18.52¢ per kWh through June 2025. That is a rise of about 12.9% in one year.
June's numbers were even higher. Home electricity averaged 21.73¢ per kWh in June 2026, up from 19.69¢ per kWh in June 2025.
The question is no longer whether Pennsylvania electricity has become more expensive.
It has. The more important question is why.
The answer involves several forces happening at the same time.
How Much Have Pennsylvania Electricity Rates Increased?
Across the state, the average home price rose from 18.52¢ per kWh to 20.90¢ per kWh. That compares the first six months of 2026 with the same months of 2025.
Say your home uses 1,000 kWh a month. A jump of 2.38¢ per kWh adds about $23.80 a month. That is about $286 more per year, if your usage stays the same.
That does not mean every bill rose by exactly that amount. Your actual bill depends on your utility, your supplier, how much power you use, delivery charges, riders (extra line-item charges) and the weather.
But statewide, the upward trend is significant.
Why Are Pennsylvania Electricity Rates Rising? PJM Capacity Costs
Pennsylvania is part of PJM Interconnection. PJM is the regional grid operator that runs the power system across 13 states and Washington, D.C.
PJM does more than move power around the region. It also runs a capacity market. That market pays power plants to be ready, so there is enough supply to meet future demand.
That market has become much more important. PJM says demand for power is now growing faster than new power plants can be built. PJM has also named data centers as the main driver of today's demand growth.
New data centers can often be built two to three times faster than many new power plants. When expected demand grows faster than supply, reliable power plants become more valuable. Over time, that can raise what homeowners pay.
Pennsylvania Is Seeing Major Data-Center Growth
Data-center demand is not only a Virginia or Ohio issue. Pennsylvania is now a major part of PJM's large-load story. (A “large load” is a single customer that uses a huge amount of power.)
PJM has identified the PPL service area in Pennsylvania as one of the main places with concentrated large-load growth. A 2026 regulatory filing showed that about 80% of PJM's total large-load adjustments were in just four utility zones. Those zones are in Virginia, Ohio, Illinois and Pennsylvania. The Pennsylvania zone is PPL's.
PJM's planning models also added about 3.5 GW of new data-center demand in the PPL zone beyond earlier forecasts. That is an enormous amount of new demand.
Are Data Centers Causing Pennsylvania Residential Bills to Rise?
Not in a simple one-to-one way. A data center being built does not mean the utility added its electric bill to yours. That is not how electricity rates work.
But data centers can affect the larger power system. Big clusters of new demand can require more power plants, larger substations, new transmission lines, grid upgrades, new reliability projects and more capacity purchases.
Those costs and supply pressures can affect the regional power market that Pennsylvania is part of.
The more accurate conclusion: data centers are one of the major forces driving up demand. That adds to wider pressure on supply, capacity and transmission.
Pennsylvania Is Facing Major Transmission Investment
Power travels from power plants over high-voltage transmission lines before it reaches your local utility. That network now needs a major expansion.
PJM's 2025 Regional Transmission Expansion Plan included about $11.6 billion in planned new high-voltage grid projects. Pennsylvania's Office of Consumer Advocate estimated that home customers across the affected system could ultimately be charged about $9 billion of those costs.
One proposed project shows the scale. The Kammer-Juniata project would add about 221 miles of 765-kV transmission line. It would run from West Virginia through nine Pennsylvania counties. Its estimated cost is nearly $2 billion.
The Office of Consumer Advocate argued that the project was chosen largely because of new expected data-center demand in PPL territory.
This is why transmission is becoming such a big part of the conversation about electricity rates.
Generation, Transmission and Distribution Are Different
A Pennsylvania electric bill usually combines several different costs. The three most important are:
- Generation — the actual electricity produced or purchased for you
- Transmission — the high-voltage system moving power across the regional grid
- Distribution — the local poles, wires, transformers and equipment delivering electricity to your property
These three costs do not always move together. Generation could go down while transmission goes up. Distribution could stay fairly steady while supplier pricing rises.
That is why saying “my utility raised my rate” does not always explain what actually happened.
Pennsylvania's Electricity Choice Market Matters
Many Pennsylvania homeowners can choose who supplies their electricity. Your local utility still delivers the power. But another company may supply the generation part of your bill.
So your bill may depend heavily on your supplier. Key details include your contract rate, when the contract ends, fixed versus variable pricing, monthly fees and promotional terms. It also depends on your utility's Price to Compare.
Two neighbors with identical homes and the same utility can pay different generation rates.
That makes a supplier review one of the first steps when you are looking into a high bill.
Check Your Utility's Price to Compare
The Price to Compare is your utility's default supply price. Use it as the benchmark when you look at other electricity offers. If you choose another supplier, compare its rate and contract terms with your utility's current Price to Compare.
Pennsylvania utilities include PPL Electric, PECO, Met-Ed, Penelec, Penn Power, West Penn Power, Duquesne Light and UGI Electric. The right comparison depends on which one serves your home.
More Generation Is Trying to Enter PJM — But It Takes Time
There is encouraging news. PJM said in April 2026 that more than 800 new power projects had entered the first round of its reformed interconnection (grid-connection) process. Together they made up about 220,222 MW of proposed generation and storage.
That includes natural gas, battery storage, nuclear, solar, solar plus storage, wind and hydro.
But proposed power plants do not start running overnight. Projects must get through grid studies, permits, financing, hookup to the grid and construction.
Meanwhile, PJM expects demand to grow by more than 30 GW between 2024 and 2030, driven largely by data centers. That timing gap is a major part of the problem.
Pennsylvania Electricity Demand Is Part of a Much Bigger PJM Trend
PJM's 2026 long-term forecast says summer peak demand could grow by roughly 66 GW over the next 10 years. That would bring it to about 222 GW by 2036, and close to 253 GW by 2046. That is a dramatic change in demand across the region.
By one estimate, data-center load made up about 9% of PJM's wholesale power costs in the first seven months of 2026.
That puts Pennsylvania homeowners inside one of the fastest-changing power markets in the country.
Weather Can Make Higher Rates Hurt Even More
Your rate is only half of your electric bill. The other half is how much power you use.
Pennsylvania homes can see big seasonal swings. Summer air conditioning raises usage. Winter heating can do the same. That is especially true in homes with electric resistance heat, heat pumps, backup heat or electric water heaters.
If prices rise at the same time your usage rises, the bill jump can look dramatic. That is why you should compare kWh usage, not just total dollars.
What Should You Check If Your Pennsylvania Electric Bill Jumped?
If your bill rose sharply, look at five things.
- Compare kWh usage. Compare this month with the same month last year. If your usage went up a lot, part of the problem is inside the home.
- Check your supplier. Look for the supplier name, the current cents-per-kWh rate and whether the contract is fixed or variable. Also check when the contract ends and any monthly supplier fees.
- Compare with the Price to Compare. See whether your supplier still beats your utility's default generation rate.
- Check HVAC performance. Heating and cooling are often among the biggest energy users in a home. Older equipment can sharply increase usage.
- Look for new loads. EV charging, a hot tub, pool equipment, more people in the home, work-from-home schedules, electric heaters or aging appliances.
Sometimes a big bill increase is partly a rate problem and partly a usage problem.
What Can Pennsylvania Homeowners Control?
You cannot control PJM capacity markets, regional transmission projects, data-center construction, power-plant closures or future utility rate cases.
You can control how much power you use and who supplies it. You can also control your HVAC and home efficiency. And you can decide whether solar makes financial sense and whether battery storage fits your goals.
That distinction matters.
HVAC, Solar and Battery Solve Different Problems
These technologies are often grouped together. But they solve different problems.
HVAC affects consumption. A more efficient heating and cooling system can cut how much power the home needs.
Solar affects generation. Solar lets a home produce some of its own power instead of buying every kilowatt-hour from the grid.
Battery storage affects when electricity is available. A battery can store power for later. Depending on the design, it can also provide backup power during outages.
The right energy plan may involve one of these. Or it may involve several.
Does Solar Make Sense in Pennsylvania in 2026?
Rising electricity rates do not mean every homeowner should go solar. But they do change the math.
The real comparison is not simply today's electric bill versus today's solar payment.
The larger question:
What will this household spend purchasing electricity from the grid during the next 10, 20 or 25 years?
If grid power keeps getting more expensive, making part of your power at home may become more valuable.
A proper analysis should look at roof direction, shading, yearly usage and your utility. It should also cover expected solar production, financing, available incentives, roof condition and how long you plan to stay in the home.
Solar should solve a money problem, not just respond to a headline.

Ashborn Partners helps Pennsylvania homeowners understand both the electric bill and the house using the power.
We look at your usage, utility setup, supplier pricing, HVAC, solar, battery storage, roofing and whole-home efficiency before recommending a solution.
Lowering an electric bill does not always start with producing more power. Sometimes it starts with using less.
You cannot control PJM's electricity market.
You can control how dependent your home is on it.
