Overview
Okumino is a 1,500 MW hydroelectric power plant in Japan, operated by Chubu. It contributes to the country's renewable energy mix and grid stability.
Okumino is a large-scale hydroelectric power plant located in Japan, with an operational capacity of 1,500 megawatts. Owned and operated by Chubu, the facility plays a significant role in the region's power generation, leveraging Japan's mountainous terrain and abundant water resources for clean energy production. As a hydroelectric plant, Okumino utilizes the natural flow of water to generate electricity without direct fuel combustion, resulting in minimal emissions of CO2, SOx, and NOx. The plant's capacity places it among the larger hydro facilities in Japan, contributing to the country's goal of increasing renewable energy share. Japan's regulatory framework for hydroelectric power includes the Act on Promotion of New Energy and the Feed-in Tariff scheme, which support such projects. Environmentally, Okumino's operation avoids the air pollutants associated with fossil fuel plants, though it may involve considerations related to aquatic ecosystems and water flow management. The plant's output supports grid reliability and helps meet peak demand, serving as a key asset in Chubu's generation portfolio and contributing to Japan's energy security.
Environmental context
Okumino's hydroelectric operation produces no direct CO2, SOx, or NOx emissions, offering a clean alternative to thermal power. However, the facility may affect local aquatic habitats and water flow regimes, requiring careful management to minimize ecological disruption. Its location in Japan's mountainous region aligns with typical hydro development, balancing renewable energy benefits with environmental stewardship.
