For two decades, U.S. electricity demand remained relatively constant. But those days are long gone. The grid is now facing enormous demand growth thanks to today’s AI explosion. This sudden surge is breaking historical pricing models, creating a supply and demand imbalance that is pushing wholesale electricity prices and consumer costs steadily higher. The data center boom is now a dominant force reshaping the economics of American power.
U.S. power demand is now projected to increase from 4.0 TWh in 2025 to 5.3 TWh in 2040, according to Jeffries’ “US Gas Generation M&A Bible.” By 2030, data centers alone will required roughly 50 GW of electricity. This has created a seller’s market for power and placed upward pressure on prices from the wholesale market down to the utility bill.
Scarcity, Capacity Auctions, and Sky High Prices
The most immediately visible impact of data center growth on power prices is occurring in the wholesale markets that ensure grid reliability. These capacity auctions pay power plants to be available in future years, and their results are a direct measure of supply and demand.
In PJM, the nation’s largest grid operator, the capacity auction for the 2026/2027 delivery year cleared at the federal price cap of $329/MW-day. This record-high price is driven by increased demand from AI data centers, the retirement of older power plants, and delays in new generation projects connecting to the grid. This price signals a market screaming for more reliable generation. These excessively high capacity costs are not absorbed by utilities, but are directly passed on to consumers who are now seeing rising electricity bills.
The U.S. Energy Information Administration forecasts that electricity prices will continue to rise in 2026, citing growing demand from the commercial sector and data centers. According to their latest short-term outlook, the load-weighted average of the 11 regional wholesale prices is $47/MWh in 2025, which is 23% higher than the 2024 average. In 2026, it will be $51/MWh, which is an additional 8.5% increase.
Hyperscale Deals and Power Contract “Bid-Ups”
Faced with a capacity crunch, tech giants like Amazon, Microsoft, and Google are not waiting in line. They are proactively entering the market, signing long-term power purchase agreements (PPAs) that lock in supply at premium prices, thereby driving the market higher for everyone else. In 2024, long-term corporate PPA’s for renewables alone increased by 35%. According to BloombergNEF, the tech industry in the U.S. drove the majority of this growth.
Some examples:
Talen Energy & Amazon: Secured a 1,920-MW PPA, one of the largest of its kind, to power Amazon data centers from the Susquehanna nuclear plant.
Constellation & Mircrosoft: Announced a deal to restart the Three Mile Island nuclear unit, backed by a long-term PPA with Microsoft.
Entergy & Meta: Filed to build new gas-fired plants specifically for a Meta data center, sharing costs and locking in a dedicated power supply.
By entering lengthy contracts at rates that support the construction of new, expensive power plants or the revival of retired ones, these companies are effectively setting a new, higher floor for the value of power. This “bid-up” effect makes it more expensive for other commercial and industrial customers to secure their own power and raises the overall market price.
How the M&A Frenzy is Revaluing Generation
Today, we are seeing a gold rush for generation assets. Strategic power companies are buying up gas-fired power plants, betting that the era of low power prices is over.
Constellation’s acquisition of Calpine and NRG’s purchase of LS Power’s portfolio are multi-billion-dollar bets that high costs are here to stay. This M&A frenzy has a circular effect: the high prices paid for these power plants are justified by the expectation of continued high electricity prices, thereby cementing that very reality into the market’s structure.
The cost of building new gas generation to meet demand has also exploded. The last wave of CCGT power plants cost $1,200–$1,600 per kW in 2023–2024 and $800–$1,000 per kW in 2015–2022. But new projects today are coming in at over $2,500 per kW. This massive capital spending, driven by supply chain constraints and high demand for turbines, means that any new power coming online will need to earn a return at significantly higher electricity prices, locking in elevated costs for the long term.
A Higher-Priced Future?
The data center boom is creating a new, more expensive normal for U.S. electricity markets. For consumers, this means the steady electricity bills of the past are likely over (at least for now). For businesses, energy procurement is now a strategic challenge. And for investors and policymakers, the demand for reliable power is colliding with the realities of a strained grid and the high costs of new construction. Time will tell if eventual surplus generation, a tapering off of demand growth, or other inventive solutions can bring prices back down.
