AI is driving billions into gas and nuclear while federal cuts sideline solar and storage. What it means for grid costs, reliability, and existing solar.
AI is driving electricity demand to levels the U.S. grid hasn't seen in decades. How the country chooses to meet it is taking shape fast.
In July 2025, Blackstone unveiled a $25 billion plan to build data centers next to gas plants in Pennsylvania. Talen Energy agreed to buy two large gas plants to serve data center demand. Microsoft is backing the restart of a reactor at Three Mile Island. Meanwhile, federal cuts are sidelining solar and storage.
Here is where the money is going, why clean energy is being left behind, and what it means for grid costs and existing solar.
How Are Companies Powering the AI Boom?
Major investors and tech companies are betting heavily on gas and nuclear to power AI data centers, according to Canary Media and company announcements. The deals are large and moving quickly.
Recent examples:
- ●Blackstone. A $25 billion plan to build data centers adjacent to gas power plants in Pennsylvania, according to Canary Media.
- ●Talen Energy. Agreed to buy two combined-cycle gas plants in Pennsylvania and Ohio, totaling about 2.9 GW, from Caithness Energy. Talen valued the deal at $3.5 billion, and Bloomberg reported it at $3.8 billion.
- ●Microsoft. Plans to restart a reactor at Three Mile Island to supply its computing operations.
Talen CEO Mac McFarland said the deal adds "modern, highly efficient baseload" plants in markets "where we are an innovator in data center contracting."
Why Are Data Centers Turning to Gas?
Gas plants deliver dispatchable power around the clock, which is exactly what data centers want. Buying existing plants also skips the long wait to build new ones.
But power from a gas plant isn't unique. Solar, wind, and storage generate the same electrons, and new solar and storage can be built faster than new gas plants.
The cost picture has also shifted. Natural gas was long seen as the cheap option, but that assumption no longer holds. Lazard's latest analysis shows renewables still offer the lowest levelized cost even as all prices rise.
How Fast Can New Power Come Online?
Speed is the key constraint in the AI race, and solar and storage are generally the fastest new resources to build, while new gas plants face long equipment waits. Canary Media has reported that developers ordering new gas turbines face wait times of up to five to seven years.
That's why buying existing gas plants is so attractive to data center developers. It's power that already exists.
But it also means those deals don't add new supply. They shift existing generation from the broader grid to specific customers, while new capacity has to come from somewhere else. For most of the country, the fastest "somewhere else" has been solar and storage.
How Are Federal Cuts Affecting Clean Energy?
Rhodium Group estimates the One Big Beautiful Bill Act will shrink new clean capacity additions by 57% to 62% from 2025 through 2035. Canary Media summarized it as eliminating about 60% of the clean power the U.S. would otherwise have built over the next decade.
At the same time, aging fossil plants are being kept online. Canary Media reported that the administration twice ordered power plants to stay open as they approached closure. Energy experts said those orders weren't needed and could cost consumers tens or hundreds of millions of dollars.
We covered the cost of those orders in DOE emergency orders for coal and gas plants.
AI and clean energy should be natural partners. Instead, policy is pushing them apart.
What Happens When Power Goes to Private Data Centers?
When generation is contracted directly to data centers, that power is no longer available to the broader grid, and replacing it takes time. Everyone else can end up paying more for what's left.
The risks for regular customers:
- ●Higher rates. Less available supply pushes up wholesale and capacity prices.
- ●Lower reliability. Less spare capacity during peak demand.
- ●Less flexibility. Fewer resources the grid operator can call on in an emergency.
- ●Slower decarbonization. Fossil plants locked into long contracts instead of retiring.
There are better models. Data centers can become grid assets by shifting load during peak hours instead of adding to it.
Do We Need Every Energy Source?
Yes. Meeting AI-driven demand will take gas, solar, wind, nuclear, and storage, but cutting support for the cheapest and fastest-deploying options makes the job harder and more expensive.
The grid wasn't designed for hyperscale data centers running at full load while also moving away from fossil fuels. Every resource has a role.
What doesn't make sense is sidelining the resources that can be built fastest at the moment demand is rising fastest. That's not pragmatism. It raises costs and slows everything down.
What Does This Mean for Existing Solar Owners?
As new clean capacity slows and data centers compete for power, existing solar becomes more valuable because it's already built, connected, and producing.
Existing systems don't need new permits, new land, or a spot in an interconnection queue. They just need to keep running.
That's where many commercial systems fall short. Aging inverters and degraded panels quietly cut output. Repowering an aging PV system can restore that output using the grid connection you already have.
