 We are pleased to announce that ENEOS Corporation (President and CEO: Takeshi Saito; hereinafter "ENEOS") completed the switchover from the FIT system*1 to the FIP system*1on February 1 (Wednesday) at the Yatsushiro Mega Solar Power Plant*2 (Yatsushiro City, Kumamoto Prefecture; hereinafter "the plant"), which started commercial operation in December 2021.

 ENEOS has been conducting a verification experiment*3 with Toshiba Energy Systems & Solutions Corporation (President & CEO: Tadashi Yotsuyanagi, hereinafter "Toshiba ESS"), a pioneer in renewable energy power generation forecasting, regarding power plant operation under FIP system. By taking advantage of the experiment, ENEOS has recently switched this power plant to the FIP system in order to quickly respond to the FIP system, which is a new system to make renewable energy the main power source.

 Under the FIP system, renewable energy power producers have obligation of balancing*4 based on accurate power generation forecasts. Services related to power generation forecasting for this power plant will be provided by Next Kraftweke Toshiba Corporation (President: Hideki Shingai, hereinafter "TNK"), a subsidiary of Toshiba ESS. JRE Trading Corporation (President: Takahisa Nakagawa, hereinafter "JRET"), a wholly owned subsidiary of Japan Renewable Energy Corporation (Head Office: Minato-ku, Tokyo; President: Kazuhiro Takeuchi; hereinafter "JRE"), will act as a renewable energy aggregator*5 to sell the power from the plant as well as the non-fossil value of the FIP system to the electricity market.

 ENEOS, JRET and TNK will make efforts to ensure stable operation of this power plant and promote operation and management in accordance with the FIP system.
