Electric avenues: AI data centers’ energy needs spur natural gas, solar growth, challenge power grids
The rapid expansion of AI data centers is increasing demand for electricity, prompting developers to pursue natural gas, solar and nuclear power while adding pressure to the U.S. grid. A Chevron-Microsoft project near Pecos, Texas, will use an off-grid natural gas plant, while other companies are pursuing nuclear-powered data center arrangements in Pennsylvania and Iowa.
AI data centers require substantially more electricity than conventional facilities, driving new demand for natural gas generation, renewable power, nuclear energy and upgraded transmission infrastructure. Analysts cited in the article say natural gas is likely to supply much of the near-term growth because it can be connected to pipelines and deployed faster, although methane emissions and broader climate impacts remain concerns.
Chevron and Microsoft announced a 20-year agreement for an off-meter natural gas plant and a 2.67-gigawatt AI data center near Pecos, Texas. Constellation Energy is investing $1.6 billion to restart a reactor at Pennsylvania's Three Mile Island site for Microsoft's data centers, while NextEra Energy and Google are pursuing the reopening of Iowa's Duane Arnold nuclear plant. The Trump administration has supported on-site power generation and announced federal funding for transmission upgrades, but opponents warn that data center electricity demand could increase emissions and utility costs for ratepayers.
