Hekinan power station: Major Coal Power Plant in Aichi, Japan

Hekinan power station is a major coal-fired power plant located in Hekinan, Aichi Prefecture, Japan. With a capacity of 4,100 MW, it is one of the largest coal power stations in Japan and plays a significant role in the country's energy mix. The plant is owned and operated by Chubu Electric Power Co Inc, a major utility serving the Chubu region. The facility operates under Japan's stringent environmental regulations, including the Air Pollution Control Act and the Act on Promotion of Global Warming Countermeasures. As a coal-fired plant, it utilizes advanced emission control technologies such as flue-gas desulfurization and selective catalytic reduction to reduce SOx and NOx emissions. The plant's large capacity and coal fuel source place it within the high-emission category for CO2, aligning with Japan's efforts to balance energy security with decarbonization goals. Hekinan power station is strategically located on the coast to facilitate coal imports and cooling water access. It serves as a critical baseload power source for the industrial and residential sectors in central Japan. The plant's operational status and capacity underscore its importance in maintaining grid stability, though its coal dependency positions it within ongoing discussions about Japan's transition to cleaner energy sources.

The plant's coal fuel source results in significant CO2 emissions, contributing to Japan's greenhouse gas profile. Its coastal location and large capacity necessitate robust environmental management to mitigate local air and water impacts. Proximity to populated areas in Aichi Prefecture requires compliance with strict national air quality standards, and the plant's age and technology influence its emission intensity relative to newer, more efficient units.
