Japan to Restart Largest Nuclear Plant

Niigata assembly's approval enables TEPCO to restart Japan's largest nuclear plant, potentially boosting Tokyo's power supply by 2% amid energy security concerns.

  • Coming in early 2026, Niigata Governor Hideyo Hanazumi approved the restart of KK's Unit 6, with TEPCO planning to bring it online around Jan 20, 2026, for a soft launch.
  • Tokyo has suffered power shortages in recent years, prompting the LDP-led Strategic Energy Plan to stress maximum utilisation of nuclear power as Japan's energy self-sufficiency stands at 15.2 per cent with nuclear at 10.5 per cent, targeting 20 per cent by March 2041.
  • Preparing Units 6 and 7, Tokyo Electric Power Company completed 1.2 trillion yen in upgrades including a 15m-tall seawall, 20 backup generator vehicles, 42 truck-mounted fire pumps, and a 20,000 cu m reservoir.
  • The plant's 8.2 gigawatt capacity could supply more than 13 million homes, and TEPCO pledged a 100 billion yen fund over 10 years to support Niigata's local economy.
  • Despite engaging over 40,000 residents, TEPCO still faces public distrust and local opposition in Niigata, where 50% support and 47% oppose restart, a Dec 11 survey shows.
