NSC Muroran Works power station - Coal Power Plant in Muroran, Japan

NSC Muroran Works power station is a coal-fired power plant located in Muroran, Hokkaido, Japan. With a capacity of 195 MW, it is a medium-scale facility that provides electricity to the adjacent steelworks and contributes to the regional power grid. The plant is owned and operated by Nippon Steel & Sumitomo Metal, a major Japanese steelmaker. The plant operates under Japan's regulatory framework for thermal power generation, which includes emission standards for SOx, NOx, and particulate matter under the Air Pollution Control Act. As a coal-fired facility, it uses subcritical or supercritical technology typical of older Japanese coal plants. The plant's capacity of 195 MW places it in the small-to-medium range for coal power in Japan. Environmentally, the plant's coal combustion results in CO2, SOx, and NOx emissions. Its location in an industrial area of Muroran, near residential zones, necessitates compliance with local air quality standards. The plant plays a role in supporting the steel industry's energy needs and the local economy.

The plant's coal-fired generation produces significant CO2 emissions, contributing to Japan's greenhouse gas inventory. SOx and NOx emissions are regulated under national standards, and the plant likely uses flue-gas desulfurization and selective catalytic reduction to meet limits. Proximity to Muroran's urban area requires careful monitoring of air quality impacts.
