Misumi power station: 1,000 MW Coal Power Plant in Japan

Misumi power station is a coal-fired power plant located in Japan, with a capacity of 1,000 MW. It is owned and operated by Chugoku Electric Power Co, a major utility in the Chugoku region. The plant is operational and contributes significantly to the area's electricity supply. The facility uses coal as its primary fuel, a common choice for baseload power generation in Japan. Coal plants of this scale typically employ supercritical or subcritical steam cycles. Japan's power generation sector operates under strict environmental regulations, including emission limits for SOx, NOx, and particulates, aligned with national air quality standards. As a large coal-fired plant, Misumi power station has a substantial environmental footprint, with CO2 emissions being a key concern. Its location near the coast facilitates fuel delivery and cooling water access. The plant supports grid stability and industrial activity in the region, though it faces regulatory pressure to reduce emissions in line with Japan's climate goals.

The plant's coal combustion releases CO2, SOx, NOx, and particulate matter, contributing to local and global environmental impacts. Proximity to populated areas may raise health concerns, though modern emission controls mitigate some effects. Japan's regulatory framework, including the Air Pollution Control Act, sets strict limits on emissions, and the plant likely employs flue-gas desulfurization and selective catalytic reduction to comply.
