Vena Energy began commercial operation of the 68.6MWAC/71.7MWDC Maniwa Solar Power Plant in Maniwa City, Okayama Prefecture, on August 15, 2026, Digital Grid announced on August 17, 2026.
According to the statement, the power plant, which was built on a former golf course, is expected to generate about 85GWh per year. Its physical output will be sold into the wholesale market via Digital Grid, which also handles generation forecasting and balancing. The associated non-fossil certificates (NFCs) will be delivered to LY Corporation under a 20-year virtual PPA.
Maniwa Solar Power Plant was awarded an 11.49-yen-per-kWh feed-in-tariff (FIT) contract in Japan’s sixth solar auction. It had to switch to the feed-in-premium (FIP) scheme to enable the virtual PPA.
LY Corporation and Vena Energy signed the deal in January 2025, marking the LINE and Yahoo! JAPAN owner’s first corporate PPA.
Japan Energy Hub’s PPA database shows the arrangement is the largest operational single-plant solar PPA disclosed in Japan. It is the second largest including deals yet to start supply after ENEOS Renewable Energy’s 15-year agreement with Equinix Japan for NFCs linked to the output of its 85MWAC/121.09MWDC Sanda Mega Solar Power Plant in Hyogo Prefecture, which is scheduled to launch in January 2027.
