Power for AI: Grid Queues, Nuclear PPAs, Gas Turbines — 2026-10-16
On October 16, PJM warned that AI-driven data-center load is eroding reserve margins, while U.S. authorities advanced restarts of three shuttered nuclear plants to meet data-center demand. Gas-turbine suppliers and behind-the-meter technologies are also moving into the AI power race, with analyses projecting a 44% rise in gas-fired capacity and batteries as a 3-5 year grid-access shortcut.

Top developments
PJM says reserves are falling as data-center load rises
On October 16, Newsweek reported that PJM official David Souder warned: “Energy flow on the system is increasing while our generation reserves are falling leaving little room for error,” with the article framing the risk as data centers leaving little room for error on America’s largest power grid. The warning matters for utility load forecasts and rate cases because reserve-margin stress shapes how regulators and grid operators evaluate new large loads, interconnection-queue congestion and the costs of maintaining reliability.
U.S. moves to restart shuttered nuclear plants for AI power demand
On October 16, AP reported that the United States is making an unprecedented attempt to revive three permanently closed nuclear plants to meet growing electricity demand, especially from data centers. India Today said the restarts are financed to expand carbon-free supply for data centres while intensifying safety and subsidy debates. The policy push matters for nuclear and SMR power purchase agreements because restarted baseload plants could provide contracted clean power, but financing, licensing and rate-case scrutiny will determine how much capacity reaches the grid.
Behind-the-meter batteries are pitched as a way to beat grid queues
On October 15, a market report distributed via Yahoo Finance said AI data-center energy storage is becoming a $4-6 billion market as workload volatility and grid bottlenecks create demand for battery systems. The report argued that behind-the-meter batteries can speed grid access by 3-5 years, while total-cost-of-ownership analysis weighs cooling, compliance and fire-suppression savings against sodium-ion premiums. This matters for interconnection queues because data-center developers may seek partial self-supply or firming arrangements rather than waiting years for utility transmission upgrades, potentially shifting costs into rate cases.
Gas capacity is projected to jump as AI centers strain grids
On October 16, NaturalNews reported that an Environment America Research and Policy Center analysis found AI infrastructure would increase gas-fired generator capacity by 44% over the next four years, with energy companies planning new gas capacity around data-center demand. The projection matters for gas-turbine backlogs because a 44% capacity increase implies sustained orders for turbines, compressors and firming assets, while also raising emissions and rate-case questions for utilities serving large loads.
Micro gas turbines are marketed as a bridge for delayed connections
On October 14, PowerGen Advancement published a technical article describing micro gas turbines as a way to provide stable on-site power for AI workloads while managing utility interconnection delays. The positioning matters because behind-the-meter generation is increasingly discussed as a workaround for large-load queues, though it can shift cost burdens and trigger regulatory review of curtailment, emissions and rate allocation.
Local view
German outlets focused on Siemens Energy’s exposure to data-center demand. ad-hoc-news.de reported that data centers accounted for about one-fifth of EUR 17.9 billion in April-June order intake and that the company had seen no cancellations despite AI-spending worries. Another ad-hoc-news.de article said DZ Bank raised its fair value while keeping a “Hold” rating, and a third reported that management expected 14-16% comparable revenue growth in 2026. 4investors.de said mwb research maintained a sell rating and a EUR 100 target despite strong growth forecasts, reflecting valuation concerns. wallstreetONLINE noted the stock’s second consecutive loss day as AI-related worries hit the sector even as Siemens Energy delivered operational records.
Japanese media reported equipment partnerships rather than new PPAs. MyNavi said Mitsubishi Heavy Industries and Ingeteam would collaborate on distribution solutions for AI data centers, published October 16. Nikkei similarly reported Mitsubishi Heavy partnering with a Spanish electrical group on AI data-center equipment. Japanese-language outlet SpazioCrypto reported that Venture Global signed a basic agreement with GE Vernova and others on October 15 for up to 10 GW of off-grid power for AI data centers by the end of 2034, but stressed the plan depends on permits and customer commitments.
