ENEOS Renewable Energy retrofitted the 32MWAC/54.23MWDC JRE Satsuma Solar Power Plant in Satsuma Town, Kagoshima Prefecture, with a 130MWh battery storage system and signed a virtual PPA with bearing manufacturer NSK for non-fossil certificates (NFCs) associated with its output, the company announced on June 18, 2026.
According to the statement, annual supply volume is expected to be about 65GWh and continue for approximately 15 years, likely until the end of the project’s feed-in-premium (FIP) contract.
METI data shows the project was certified under the feed-in-tariff (FIT) scheme in FY2013, when 10kW and larger solar power plants were eligible for 36 yen per kWh for 20 years. The asset transitioned to FIP effective April 1, 2026, and operates under a contract valid until November 2040.
JRE Satsuma Solar Power Plant began commercial operation on January 11, 2023, and is owned by the special purpose company (SPC) JRE Investment No. 2. At commissioning, SMFL Mirai Partners held a stake in the project alongside ENEOS Renewable Energy (then known as Japan Renewable Energy). It is unclear whether the Sumitomo Mitsui Financial and Leasing unit continues to own an interest in the asset.
The deal follows several other virtual PPAs signed by ENEOS Renewable Energy, including for an 85MWAC/121.09MWDC solar power plant with Equinix and for a 9.5MW asset with Amazon. While the company previously entered into a PPA using a solar-plus-battery hybrid asset with Tokyo Metro, the scheme with NSK is the first known time it has done so with an extra high-voltage project.
