Tedorigawa Daiichi Hydroelectric Power Plant, Japan | 250 MW Capacity

Tedorigawa Daiichi is a hydroelectric power plant located in Japan, with an installed capacity of 250 megawatts (MW). Operated by EPDC, the facility is currently operational and plays a role in Japan's power generation mix. As a hydroelectric plant, it utilizes water flow to generate electricity, aligning with Japan's efforts to diversify its energy sources. Japan's power sector is regulated under the Electricity Business Act, which sets standards for safety, reliability, and environmental performance. Hydroelectric plants like Tedorigawa Daiichi are subject to water usage rights and environmental impact assessments. The plant's capacity of 250 MW places it in the medium-to-large scale for hydroelectric facilities in Japan, where typical hydro plants range from small run-of-river to large storage projects. As a renewable energy source, Tedorigawa Daiichi contributes to reducing greenhouse gas emissions compared to fossil fuel-based generation. Its operation supports grid stability and provides clean electricity to the region. The plant's location in Japan's mountainous terrain is typical for hydroelectric projects, leveraging natural water resources for power generation.

Hydroelectric power generation has a low carbon footprint but can affect local aquatic ecosystems and water flow regimes. Tedorigawa Daiichi's operation may involve reservoir management, which can alter downstream habitats. In Japan, hydro projects are subject to environmental assessments to mitigate impacts on fish migration and water quality. The plant's location in a region with significant rainfall supports its renewable energy output.
