Constellation Energy’s Crane Clean Energy Center on Three Mile Island in Pennsylvania is refurbishing Unit 1, with a $1.6 billion project cost and a $1 billion DOE loan; Microsoft has signed a 20‑year power contract and the plant should deliver 835 MW in 2027. The Duane Arnold Energy Center in Iowa, a partnership between NextEra Energy and Google, targets 615 MW by 2029, with Google covering costs so Iowa residential customers are not charged.\n\nAnalysts note that Michigan may need 1.2‑2.3 GW for data centers by 2030, Pennsylvania 0.8‑3.4 GW, and Iowa 1.55‑2.8 GW, making the revived reactors a timely source of premium power for AI workloads.","keyPoints":["Palisades plant in Michigan will generate 800 MW by March 2027 after DOE loan funding","Crane Clean Energy Center on Three Mile Island aims for 835 MW in 2027, backed by $1.6 B project cost and a $1 B DOE loan; Microsoft signed a 20‑year contract","Duane Arnold Energy Center in Iowa, a NextEra‑Google partnership, targets 615 MW by 2029 with no cost to Iowa residential customers"],"whyItMatters":"Reviving nuclear capacity supplies the high‑power, low‑latency electricity AI data centers need, easing grid constraints and supporting the rapid growth of AI workloads.","category":{"slug":"enterprise","name":"Enterprise & Industry","url":"https://digestai.news/category/enterprise"},"entities":{"companies":["Holtec Palisades","Constellation Energy","NextEra Energy","Google","Microsoft"],"models":[],"people":["John Ketchum"]},"firstPublishedAt":"2026-10-20T12:50:00Z","updatedAt":"2026-10-20T12:50:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"Tom's Hardware","title":"US restarts three shut-down nuclear reactors to feed AI data centers","url":"https://tomshardware.com/tech-industry/big-tech/us-takes-unprecedented-step-of-recommissioning-nuclear-plants-due-to-ai-power-demand-2-25-gw-currently-on-tap-from-refurbished-reactors","publishedAt":"2026-10-20T12:50:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"US restarts three nuclear reactors to supply power for AI data centers\", 20 October 2026, https://digestai.news/story/us-restarts-three-nuclear-reactors-to-supply-power-for-ai-data-centers","publisher":"Digest AI","title":"US restarts three nuclear reactors to supply power for AI data centers","datePublished":"2026-10-20T12:50:00Z","url":"https://digestai.news/story/us-restarts-three-nuclear-reactors-to-supply-power-for-ai-data-centers"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
