Hitotsuse Hydroelectric Power Plant, Japan | 180 MW Facility

Hitotsuse is a hydroelectric power plant located in Japan, operated by Kyushu. With a capacity of 180 MW, it is a medium-scale facility within the country's hydropower sector, which plays a significant role in Japan's renewable energy mix. The plant operates under Japan's regulatory framework for renewable energy, including the Feed-in Tariff scheme that supports hydroelectric generation. As a run-of-river or reservoir-based facility, it utilizes the local water resources efficiently, contributing to grid stability and low-carbon electricity production. Hitotsuse supports the regional power grid by providing clean, renewable energy. Its operation aligns with Japan's goals to increase renewable energy share and reduce greenhouse gas emissions. The plant's location in a mountainous area likely benefits from consistent water flow, ensuring reliable generation.

As a hydroelectric plant, Hitotsuse has a low carbon footprint compared to fossil fuel plants. However, it may affect local aquatic ecosystems and water flow regimes. The facility's location in a region with significant rainfall supports its operation, but changes in precipitation patterns due to climate change could impact generation reliability. Hydro plants typically have minimal air emissions.
