Sakuma Hydroelectric Power Plant | 350 MW Facility in Japan

Sakuma is a hydroelectric power plant located in Japan, with a generating capacity of 350 megawatts. Operated by EPDC, the facility plays a role in the nation's renewable energy infrastructure, leveraging the country's mountainous terrain and water resources for clean electricity production. The plant operates under Japan's regulatory framework for renewable energy, including the Feed-in Tariff scheme that promotes hydroelectric power. As a medium-to-large scale hydro facility, Sakuma utilizes conventional dam-based technology typical of Japanese hydro projects, which often feature run-of-river or reservoir storage designs to manage seasonal water flow. Environmentally, Sakuma contributes to Japan's goals of reducing greenhouse gas emissions by displacing fossil fuel-based generation. Its operation supports local grid reliability and provides renewable energy to surrounding communities. The plant's long-term significance lies in its role within Japan's energy transition toward a lower-carbon power sector.

Hydroelectric power generation like Sakuma has a low carbon footprint but can affect local aquatic ecosystems and river flow regimes. In Japan, such facilities are subject to environmental impact assessments and water management regulations. The plant's location in a region with significant rainfall and mountainous terrain supports consistent hydro generation, though seasonal variations can influence output.
