Japan restarted one reactor at Kashiwazaki-Kariwa, the world's largest nuclear power station, after 14 years offline. This restart enabled the utility TEPCO to start curtailing solar farm output up to 3,290 megawatts, reflecting a shift in the regional energy mix amid rising LNG prices following the Strait of Hormuz closure.
