Big Tech's insatiable hunger for reliable, carbon-free power is fueling a global nuclear renaissance, with Microsoft, Amazon, and Google signing landmark deals to revive dormant reactors and deploy next-gen small modular reactors (SMRs) specifically for AI data centers . Goldman Sachs projects U.S. data center electricity demand surging 160-175% by 2030, equivalent to adding a top-10 power-consuming nation, as AI models demand constant baseload energy beyond intermittent renewables. India's entry via NTPC's thorium partnerships and the SHANTI Act signals Asia's pivot to atomic power for its own tech ambitions .
Big Tech's Nuclear Power Plays
- Microsoft & Three Mile Island: Under a 20-year PPA, Microsoft secured 835 MW from Constellation Energy's Crane Clean Energy Center (formerly TMI Unit 1), targeting 2027 restart with $1B federal loan support; the site is 80% staffed despite skeptics.
- Amazon & Susquehanna: Expanded deal with Talen Energy delivers up to 1,920 MW through 2042, shifting to "front-of-meter" supply for Pennsylvania data centers while exploring SMRs and plant uprates.
- Google & Kairos Power: Master agreement for 500 MW from 6-7 SMRs, first online by 2030, supporting 24/7 carbon-free goals with iterative deployments through 2035.
These deals mark the first U.S. nuclear restarts for private customers, blending 20th-century infrastructure with AI's 21st-century demands.
India's Nuclear Leap Forward
State utility NTPC targets 30 GW nuclear capacity by 2047 ($62B investment), aligning with national 100 GW goal and 2 GW operational by 2032, via minority stake in U.S.-based Clean Core Thorium Energy (CCTE) . CCTE's ANEEL thorium-uranium fuel suits India's heavy water reactors; U.S. DOE export license enables partnership post-SHANTI Act passage . The SHANTI Act (2025) ends government monopoly, caps private equity at 49%, and licenses private firms for reactors, fuel fabrication, and decommissioning under oversight.
NTPC shares surged 4-4.5% on announcement, reflecting investor bets on diversification from coal.
U.S. Regulatory Green Lights
FERC's December 18, 2025 order mandates PJM revisions for data center co-location at plants, creating three transmission services to speed interconnections without full grid studies . Duke Energy filed NRC early site permit December 30 for 600 MW SMRs at Belews Creek coal site (retiring 2030s), eyeing 2036-2037 operation amid Trump-era executive orders quadrupling capacity to 400 GW by 2050 .
Future Power Horizon
World Nuclear Association eyes 1,428 GW global capacity by 2050; AI's grid strain positions nuclear as essential for net-zero while enabling tech growth . India-U.S. thorium ties could fuel emerging markets' AI boom, blending energy security with innovation . Challenges remain—NRC approvals, costs, timelines—but momentum builds as renewables falter on reliability.
