Shin Toyone Hydroelectric Power Plant, Japan | 1,125 MW Facility

Shin Toyone is a large-scale hydroelectric power plant located in Japan, with an installed capacity of 1,125 megawatts (MW). Operated by the Electric Power Development Company (EPDC), this facility plays a significant role in the country's energy mix, leveraging Japan's mountainous terrain and abundant water resources for clean electricity generation. As a hydroelectric plant, Shin Toyone operates without direct fuel combustion, resulting in negligible emissions of CO2, SOx, and NOx. The facility uses advanced turbine technology to convert the kinetic energy of flowing water into electricity. Japan's regulatory framework for hydropower includes the Renewable Energy Act and strict environmental impact assessments to ensure sustainable operation. The plant's substantial capacity positions it as a key asset in Japan's power grid, supporting grid stability and peak demand management. By generating renewable energy, Shin Toyone contributes to Japan's goals of reducing greenhouse gas emissions and increasing the share of renewables in its energy portfolio.

Shin Toyone's hydroelectric operation produces no direct air emissions, making it a low-carbon energy source. The plant's location in a region with significant rainfall and mountainous topography ensures a reliable water supply. However, large-scale hydropower can affect local aquatic ecosystems and river flow regimes. Japan's environmental regulations require measures to mitigate such impacts, including fish passage facilities and minimum flow requirements.
