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 1,250MW in March 2025. Based on this renewable energy capacity, we displaced approximately 680,000t-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:

To expand our renewable energy business, we continue to pursue various challenges. For offshore wind power, which is expected to expand in the medium term, we are developing the offshore wind power plant off the coast of Happo and Noshiro in Akita Prefecture, where the project company led by our company was selected as the operator in March 2024. In response to the situation where suitable land for developing large-scale solar power plants in Japan is becoming limited, we are advancing development through a “bulk scheme” that develops solar power plants in collaboration with companies that have development know-how in each region. In fiscal 2024, we began development and operation of solar power plants with a total capacity of approximately 60 MW across three regions through this scheme. Additionally, to reduce the risk of output curtailment and ensure stable supply of renewable energy, we are promoting the installation of storage batteries at solar power plants.
