Washington Pivots to Gas, Coal and Nuclear for AI Baseload Power
- The Trump Administration is prioritizing gas, coal, and nuclear as the backbone of new power generation to support surging data-center demand.
- Grid reliability is the near-term risk, as new baseload plants face long lead times, rising costs, and equipment bottlenecks, even as retirements of fossil plants are delayed.
- Natural gas leads the next wave, with renewables and storage filling short-term gaps, while nuclear is positioned as a longer-term solution post-2030 once permitting and construction hurdles are cleared.
The Trump Administration last week gave the latest and clearest signal yet that it prefers natural gas, coal, and nuclear power to provide the bulk of new generation supporting the data center build-out.
Interior Secretary Doug Burgum, Energy Secretary Chris Wright, and the bipartisan group of governors of all 13 states served by PJM Interconnection issued a so-called Statement of Principles urging the biggest U.S. power grid operator to hold a capacity auction, in which leading technology companies have committed to funding this new generation capacity. This would protect residential electricity rates and ensure data centers pay their fair share, while strengthening grid reliability, the Trump Administration says.
Coal, natural gas, and nuclear will be the pillars of the new U.S. power capacity, providing reliable baseload, and ending years of “misguided policies” that favored intermittent energy resources such as solar and wind power, the U.S. Administration said.
“High electricity prices are a choice,” Energy Secretary Chris Wright said.
“The Biden administration’s forceful closures of coal and natural gas plants without reliable replacements left the United States in an energy emergency. Perhaps no region in America is more at risk than PJM. That’s why President Trump asked governors across the Mid-Atlantic to come together and call upon PJM to allow America to build big, reliable power plants again,” Secretary Wright added.
Despite the push, new coal, gas, and nuclear power plants are years away from building and commissioning, exposing the U.S. power market to threats to grid stability and reliability in the near term.
The Administration’s policy has already pushed more than half of the power plants in the PJM market running on fossil fuels to either defer or cancel plans to retire as soaring electricity demand from AI data centers has operators use all available capacity to ensure the flexibility and reliability of the grids.
At the end of last year, the U.S. Department of Energy extended a $1-billion loan to help Constellation Energy restart the Three Mile Island Unit 1 nuclear reactor to add baseload power to the grid and help the AI advancement in the United States.
Nuclear energy will be one of several winners of the AI and data center boom, alongside natural gas and power purchase agreements for renewable energy.
“Natural gas will benefit significantly from the rising electricity demand and the requirement for 24/7 uninterrupted supply. It is most flexible among all energy sources and an abundant domestic resource,” Goldman Sachs said a report last year.
Still, the lead time for new combined-cycle gas power plants has jumped to five years in 2025 from three and a half years back in 2023, with costs soaring by 49%, per BloombergNEF data.
Bottlenecks in the supply chain of critical electrical equipment are also hindering superfast new gas plant construction.
Soaring demand for electrical materials and equipment, such as transformers and switchgear, is pressuring the sector, which has already become notorious for the long lead times on project execution, analysts at Wood Mackenzie said last year.
The challenges are likely to stay – and even escalate – as investments in manufacturing, clean energy, and data centers are boosting demand for key electrical equipment components.
GE Vernova, a key turbine maker, is sold out of turbines until 2028, and expects to be largely sold out of deliveries in 2030 by the end of 2026, chief executive Scott Strazik said on the company’s 2025 Investor Update in December.
Analysts at Goldman Sachs Research believe power sourcing for U.S. data centers will be mostly utility-scale solar, battery storage, and natural gas peaking plants in the near term. In the medium term, natural gas combined cycle will lead to new power generation, while nuclear would be an option in the long term.
Of the 82 GW of incremental capacity additions in the U.S. to serve data center-driven load through 2030, Goldman Sachs expects 51% to come from natural gas peaking plants and 27% to come from solar.
Renewables and storage will benefit in the near term before IRA incentives expire. New natural gas combined cycle plants could be online by 2029, with turbine availability being the main constraint. New nuclear plants could be ready to provide baseload capacity from 2030 or even 2035 onwards, due to long lead times to permit and construction, Goldman Sachs said.
