Overview
Okutataragi is a 1,932 MW hydroelectric power plant in Japan, operated by Kansai. It is a major pumped-storage facility supporting grid stability.
Okutataragi is a large hydroelectric power plant located in Japan, operated by Kansai Electric Power. With a capacity of 1,932 MW, it ranks among the country's significant hydroelectric facilities, contributing to Japan's renewable energy mix and grid reliability. The plant operates as a pumped-storage hydroelectric facility, which allows it to store energy by pumping water to an upper reservoir during low demand and generating electricity during peak demand. This technology is crucial for balancing the grid, especially with the increasing share of variable renewable sources like solar and wind. Japan's regulatory framework for hydroelectric power includes the Act on Promotion of New Energy and other measures to support renewable energy deployment. Okutataragi plays a vital role in Japan's energy landscape by providing flexible generation capacity and supporting grid stability. Its large capacity and pumped-storage capability make it an essential asset for integrating renewables and ensuring reliable power supply. The plant's operational status and strategic importance underscore its contribution to Japan's energy security and decarbonization goals.
Environmental context
As a hydroelectric plant, Okutataragi has a low carbon footprint compared to fossil fuel plants, but its pumped-storage operation involves water management that can affect local aquatic ecosystems. The facility's location in a mountainous region of Japan may involve considerations for biodiversity and water flow regulation. The plant's large capacity and pumped-storage technology help reduce reliance on fossil fuels, contributing to lower CO2, SOx, and NOx emissions in the region.
