What the Western Pennsylvania data center build-out is doing to your power bill
Data centers across Western Pennsylvania are pushing connection costs onto ratepayers. What the June 2026 rate changes mean for a small business, and the numbers to pull off your bill this month.

The data centers going up across Western Pennsylvania are raising electricity costs for the small businesses around them, but the size of the increase depends on your utility and your commercial rate class. West Penn Power raised its residential Price to Compare 10.3% on June 1, 2026, while Duquesne Light small commercial customers under 25 kW saw a slight decrease. Find your rate class before you assume which side you're on.
I've written before about the opportunity side of this build-out, and that side is real. Homer City is under construction. Shippingport, Springdale, and Upper Burrell are moving. Washington County has live proposals at Hanover Township's Starpointe park and the CNX site at Zediker Station in South Strabane. Construction crews and tax base follow.
The cost side is real too, and it lands on a different set of people. Ratepayers have absorbed roughly 95% of data center grid connection costs across the PJM region. That includes the 1 to 10 employee firms that make up most of the local economy.
Both things are true at the same time. Owners who only hear the first one make worse decisions about pricing, budgets, and what to tell clients who ask.
Why wholesale power costs jumped in 2026
Three separate charges moved at once, and only one of them is the energy itself. According to Monitoring Analytics, PJM's independent market monitor, average wholesale power costs reached $114.50 per megawatt hour in the first half of 2026, up 50.3% from $76.16 a year earlier. Capacity costs inside that figure went from $6.39 to $19.61 per megawatt hour, a 207% increase. Transmission congestion costs climbed 43% to $6 billion over the same period.
The second question is who pays to connect these projects to the grid. A Union of Concerned Scientists analysis of 130 large-load interconnection projects across 7 PJM states from 2022 to 2024 found that only 6 required the data center to cover its own connection costs. The rest, more than $4 billion in 2024 alone, went into general transmission charges billed to everyone on the system. Pennsylvania ratepayers absorbed $491.7 million of that 2024 total, second only to Ohio and Virginia among the states studied.
An August 18, 2026 report from the Pennsylvania Sustainable Business Network, the American Sustainable Business Network, and Compound Impact Collective puts the statewide figure at $78.3 million more per month, close to $1 billion a year. That report also projects Pennsylvania business bills could rise as much as 29% from the capacity surge. Those three groups advocate for policy change, so read the 29% as their projection. The Monitoring Analytics numbers and the utility rate filings are the harder floor.
The pressure has a runway. NRDC and other analysts project cumulative PJM capacity costs of $100 billion to $163 billion between 2028 and 2033 if the temporary price cap expires.
What this costs a small business in the South Hills
Your answer depends on your utility and your rate class, and the spread is wider than most owners expect. West Penn Power, which covers much of Washington County and southwestern Pennsylvania, raised its residential Price to Compare from 10.947 to 12.075 cents per kilowatt hour on June 1, 2026, a 10.3% increase. Post-Gazette reporting put that at about $10.67 more per month on the average residential generation charge. Duquesne Light, covering the Pittsburgh metro core, moved from 13.75 to 14.14 cents, up 2.8%.
Commercial rate classes went in different directions, and this is where owners get caught. Duquesne small commercial customers under 25 kW saw their default supply rate tick down slightly, from 9.7016 to 9.6754 cents. Duquesne commercial and industrial customers between 25 and 200 kW took a 10% increase. Same utility, same date, opposite outcomes.
So find your rate class before you assume anything. It's on your bill. A Mt. Lebanon dental practice under 25 kW on Duquesne had a quiet summer on the supply side. A Bridgeville contractor with a heated shop and a compressor bay, or a Peters Township wellness studio cycling HVAC from 6 AM to 8 PM, may be sitting in a class that moved 10%. A 10% generation increase on a $600 monthly bill is real money by December.
That increase arrives on top of insurance, labor, and materials costs that already moved. Most owners I sit with treat the electric bill as background noise, a fixed cost they glance at and pay. It stopped being fixed.
What to do about it in the next 30 days
Start with 12 months of bills and two numbers: your rate class and your average monthly kilowatt hours. Both are printed on the statement. Put usage and total cost in a spreadsheet and look at the trend line. Most owners have never done this and are surprised by what they find.
Then check whether you're still on default service. Pennsylvania deregulated its generation market, so you can shop competitive suppliers through PAPowerSwitch, the comparison site the state Public Utility Commission runs. Compare offers against your current Price to Compare, and read the contract term before you sign. Some fixed rates that look good today reset hard in 12 months.
Add energy as its own line in whatever passes for your monthly financial review. Make it a recurring 5 minute check, the same way you check lead response time or aging receivables.
And when clients or referral partners ask what the data center thing means, give them both halves of the answer. Construction activity and tax base on one side, connection costs pushed onto ratepayers on the other. Owners who can speak accurately about both get called back.
Where AI helps here is small and specific. Drop 12 months of billing data into a model and ask it to chart usage against cost per kilowatt hour, so you can see whether your problem is the rate or your consumption. Ask it to summarize a supplier contract's cancellation terms in plain English before you sign one. That's 20 minutes of work that used to be an afternoon.
Common questions
Are data centers actually why my electric bill went up in Pittsburgh?
Partly. Monitoring Analytics, PJM's independent market monitor, tied a meaningful share of the capacity cost increase to projected data center demand, and capacity cost per megawatt hour rose 207% in the first half of 2026. Weather, generation supply, and transmission congestion also move your bill, so no single cause explains all of it.
Did small business electric rates go up in the Pittsburgh area in June 2026?
It depends on your utility and rate class. Duquesne Light small commercial customers under 25 kW saw a slight decrease in their default supply rate on June 1, 2026, while Duquesne accounts between 25 and 200 kW took roughly a 10% increase. West Penn Power customers saw increases across the board.
Can a small business in Pennsylvania shop for a cheaper electricity supplier?
Yes. Pennsylvania's generation market is deregulated, and small commercial accounts can switch suppliers while the utility keeps delivering the power. Compare offers against your utility's current Price to Compare and check the contract length before you switch.
If your electric bill is something you pay without reading, that's margin sitting on the table. I work with Pittsburgh-area owner-operators to find the one workflow costing the most time or money and decide whether AI is the right fix for it.
