Google, NextEra Seal 25-Year Deal to Restart Iowa’s Duane Arnold Nuclear Plant by 2029

The agreement aims to secure round-the-clock, carbon-free power for expanding AI data centers, reflecting a broader shift to revive retired reactors.

Overview

  • Google will purchase approximately 615 MW from Duane Arnold under a 25-year contract to support its Iowa cloud and AI operations with 24/7 carbon-free power.
  • NextEra is acquiring the combined 30% stake held by Central Iowa Power Cooperative and Corn Belt Power Cooperative to become sole owner of the plant.
  • CIPCO will buy the plant’s remaining output on the same terms as Google, according to the companies.
  • Operations are targeted for early 2029 pending regulatory approvals, with a key FERC waiver granted in August and NRC coordination underway.
  • Google and NextEra also signed a framework to explore additional U.S. nuclear projects, and they project about 1,600 construction jobs, roughly 400 permanent roles, and $340 million in annual statewide economic output.
