The ESS facilities have been specifically designed to enhance the stability of the power grid by providing ancillary services, capacity services and energy arbitrage. These projects were chosen by the Ministry of Energy, Trade, and Industry (METI) under the "Subsidy for Grid Storage Battery Installation Support Project for Accelerating the Introduction of Renewable Energy in 2021" initiative.
Pacifico Energy has an impressive cumulative total of 1,172 MW (DC basis) of completed solar power plants to date, establishing itself as the largest renewable energy developer in Japan. As a leader in renewable energy development, the company established battery storage business department in 2021, and within a span of two years, it had successfully achieved commercial operation of these pioneering ESS plants.
Advancing the integration of ESS facilities into Japan’s power system is crucial for advancing renewable energy (which may fluctuate under the actual weather conditions) as the primary power source in the country. By mitigating the impacts of weather-related fluctuations in renewable energy generation and grid bottle necks, ESS facilities play a vital role in achieving this goal.
