Daini Numazawa Hydroelectric Power Plant, Japan - 460 MW Capacity

Daini Numazawa is a hydroelectric power plant located in Japan, with a capacity of 460 megawatts. It is operated by Tohoku and plays a significant role in the region's renewable energy infrastructure. The plant utilizes the natural flow of water to generate electricity, supporting Japan's energy mix with a clean and sustainable source. The facility operates under Japan's regulatory framework for renewable energy, which includes feed-in tariffs and grid connection standards. Hydroelectric plants like Daini Numazawa are typically run-of-river or reservoir-based, and this plant's capacity places it in the medium-to-large scale for hydropower in Japan. The technology involves turbines driven by water flow, with minimal emissions compared to fossil fuel plants. Environmentally, Daini Numazawa contributes to reducing greenhouse gas emissions by displacing fossil fuel generation. Its location in a mountainous region of Japan likely involves careful management of water resources and local ecosystems. The plant supports grid stability and provides clean energy to communities, aligning with Japan's goals for renewable energy expansion.

Hydroelectric power generation has a low carbon footprint but can affect local aquatic ecosystems and water flow regimes. Daini Numazawa's operation involves managing water releases to minimize ecological disruption while maintaining power output. The plant's location in a region with significant rainfall and topography supports consistent generation, but seasonal variations may influence capacity. Compared to thermal plants, hydropower avoids air pollutants like SOx and NOx, contributing to better local air quality.
