Stable supply of renewable energy and
contribution to GHG emissions reduction

ENEOS Renewable Energy develops diversified renewable energy sources, including solar, onshore and offshore wind, biomass, and hydropower. Biomass power plants started operation in 2019 and contribute greatly to stable supply of renewable energy power by around-the-clock operation regardless of the weather. ENEOS Renewable Energy’s operational capacity reached approximately 770 MW in March 2023. Based on this renewable energy capacity, we displaced approximately 510,000t-CO2 emissions annually.
We aim to contribute to the improved energy self-sufficiency of Japan and the resilience of its energy system in three different ways:

For a stable supply of renewable energy, ENEOS Renewable Energy started the following new initiatives. We constructed a solar power plant equipped with large storage batteries in 2021 and commenced its operation in 2022. We are verifying various measures such as energy time-shifting, production/demand imbalance mitigation, and enhancement of forecast technology. In addition, ENEOS Renewable Energy is conducting joint-research projects to promote offshore wind power generation with universities and other institutions. Such endeavors include the study on a new method of wind field measurement with the University of Tokyo and the study on wake flows behind wind turbines with Kyushu University. In 2022 ENEOS Renewable Energy has established a data center equipped with a solar power plant, which utilizes electricity from the solar power plant during the day, while it buys renewable energy on the non-fossil fuel value trading market in the evenings. As such, it operates as a green data center. Under the Feed-in Premium (FIP) system the ENEOS Renewable Energy Group acts as renewable energy aggregator, who bundles renewable energy power plants, manages power supply and demand utilizing storage battery systems, and performing market transactions on behalf of the power producers.

From 2021, the ENEOS Renewable Energy Group began to switch to energy purchased with non-fossil fuel energy certificates. This move allows us to purchase CO2-free electricity in addition to supplying power through the generation of renewable energy that does not emit CO2.
