HSE will sell 18GWh of non-fossil certificates (NFCs) linked to the output of its affiliates’ wind power plants to Toyo Kohan annually under a virtual PPA signed on March 27, 2026, the companies announced on May 13, 2026.
According to the statement, the supply will include three assets converted from the feed-in-tariff (FIT) to the feed-in-premium (FIP) scheme, including the 9.4MW Manyo no Sato Wind Power Plant and the 1.99MW Noshiro Port No. 1 and No. 2 Power Plants. The output will be aggregated by HSE, with 50% of the NFCs from the larger facility and all from the two smaller power plants delivered to Toyo Kohan.
Toyo Kohan plans to use the NFCs to offset emissions at its Kudamatsu Plant in Yamaguchi Prefecture. Combined with on- and off-site solar and other initiatives, it aims to cover about 25% of the facility’s power consumption with renewables by FY2030. The deal with HSE is the steel products manufacturer’s first virtual PPA.
Manyo no Sato Wind Power Plant is located in Minamisoma City, Fukushima Prefecture, and was commissioned in 2018. The two assets in Noshiro City, Akita Prefecture, came online in 2013. All three were certified under the FIT scheme when 20kW and larger onshore wind projects were offered 20-year, 22 yen per kWh contracts. HSE holds a 60% stake in the larger and 51% stakes in the smaller facilities.
The companies said they will consider signing PPAs for other assets in the future. HSE, a joint venture between Mitsubishi HC Capital (85.1%) and Hitachi Power Solutions (14.9%), holds stakes in over 30 operational and under-construction onshore wind power plants. It also has several other projects, such as the up to 68MW Shiura II and up to 280MW Tomamae, undergoing the environmental impact assessment process.
