The AI Boom’s Hidden Cost: Wholesale Prices Are Surging 41% in America’s Largest Electricity Market
Wholesale electricity prices in America's largest power market are forecast to surge at a rate that mirrors one infrastructure giant's explosive revenue growth, and the connection between those two numbers reveals who actually profits when the grid strains to keep…
Number in Focus: 41.1%
Quanta Services (NYSE:PWR | PWR Price Prediction) grew second-quarter 2026 revenue 41.1% year over year to $9.56 billion. That is almost exactly the 41% increase the U.S. Energy Information Administration forecasts for 2026 wholesale electricity prices in PJM, the country’s largest power market. Quanta’s revenue growth is a reported result from its Q2 filing dated July 30, 2026. The PJM figure is a forecast from EIA’s October Short-Term Energy Outlook, which compares 2026 with 2025.
PJM’s forecast increase is the largest of any region EIA tracks. Average U.S. wholesale prices are expected to rise 11%, to $52 per megawatt-hour, and Northwest Mid-Columbia prices are forecast to fall 23%. EIA attributes much of this year’s increase to weather, including unusually hot summer temperatures and winter storms, so data centers explain only part of the 41%. Household bills move on a separate track, because retail rates also include transmission, distribution, capacity costs and regulatory decisions.
The part that survives the weather is the build-out. Commercial electricity demand, which includes data centers, is projected to grow another 2.8% in 2027, and industrial demand is expected to rise 2.7%. Meeting that load requires transmission lines, substations, and new generation, and Quanta builds all three.
What It Means
Quanta’s growth is centered on the grid. Its Electric Infrastructure Solutions segment produced $7.84B of revenue, about 82% of the total, and its operating margin expanded to 11.5% from 10.1%. Underground Utility margins rose to 9.1% from 6.9%.
Profits grew faster than sales. Net income reached $451.4M (+96.89% YoY). Adjusted EPS of $4.24 beat the $3.03 consensus by 39.93%, the company’s fifth consecutive quarterly beat. Free cash flow came in at $886M (+470.26%). Backlog hit a record $53.44 billion, nearly 49% above $35.84B a year earlier.
Data-center work makes up about 15%-20% of the business, according to management. Quanta also self-performs 80 to 85% of its work, which means it uses its own crews instead of subcontractors. CEO Duke Austin said on the call: “I’m not sure people understand how difficult it is to interconnect the grid and how much we’re right in the middle of that interconnection.”
The same demand shows up across the power supply chain. GE Vernova (NYSE:GEV) reported a $176B backlog. Eaton (NYSE:ETN) said its electrical sector backlog grew 43%. Among power producers, Constellation Energy (NASDAQ:CEG) signed 920 MW of long-term nuclear contracts, Vistra (NYSE:VST) grew East segment adjusted EBITDA to $642M from $418M, and NRG Energy (NYSE:NRG) is developing a 1.2 GW gas plant in Texas for a hyperscaler.

Market Reaction
Quanta shares traded at $574.80 on the July 30, 2026 filing date and at $690.30 on October 9, 2026. The stock is up 8.04% over the past month, 63.68% year to date, and 55.79% over one year.
The market has rewarded the companies building the grid more than the companies selling power. Year to date, Vistra is down 1.8%, Constellation is down 15.94%, and NRG is down 32.26%.
Bull Case
The investment question is which companies can turn rising electricity demand into higher earnings without taking on too much financing risk. Quanta’s numbers fit that test. Operating cash flow rose to $1.10B (+270.44%), and management said its balance sheet and credit profile got stronger even while it paid for acquisitions, pointing to ratings upgrades by Moody’s. Eaton offers a contrast: its long-term debt rose to $18.5B from $8.8B at year-end 2025 after its acquisitions.
Quanta also raised its 2026 outlook. It now expects revenue of $39.30B–$39.70B, adjusted EPS of $16.45–$16.95 and free cash flow of $2.00B–$2.50B. Four acquisitions costing about $1.24B upfront are expected to add $1.20B–$1.40B to full-year revenue, and a new $1B buyback was authorized in May 2026. Management says customers are planning capital spending “five, seven years” out.
Management says it takes about four years to train a craft worker, and new generation capacity could become a constraint. The backlog and the guidance suggest Quanta can manage those limits.
Bottom Line
PJM’s 41% wholesale price forecast is partly a weather story. The spending on transmission, substations, and interconnection behind it will last longer, and Quanta’s 41.1% revenue growth shows where that money goes. Austin’s own view: “In many, many ways, we are just getting started.” For long-term investors, the companies building the grid have the clearest earnings exposure to rising power demand.
