Kansai Electric Power began offering the output of its existing nuclear and hydropower plants under off-site PPAs, the company announced on July 9, 2026.
According to the statement, the service is available to both power retailers and corporate offtakers, allowing them to purchase power and the associated non-fossil certificates at a fixed price. The company did not disclose offered tenors or other details.
While other utilities including Tohoku Electric Power and Chubu Electric Power have previously disclosed hydropower deals, Kansai Electric Power is the first to offer corporate PPAs for nuclear power. Both technologies allow potential buyers to add non-fossil baseload generation to their mix, complementing the prevalent solar and wind asset-backed schemes.
The new offering comes amid broader growth of the model from intermittent renewables to other technologies such as biomass and geothermal. It follows JERA’s recent announcement that it would consider offering PPAs backed by coal plants as a way to allow power retailers to limit their exposure to volatile LNG prices.
With seven operable units totaling 6.58GW, Kansai Electric Power has Japan’s largest fleet of active nuclear reactors. The utility’s hydropower portfolio includes 148 non-pumped-storage assets with a combined capacity of about 3.38GW.
