Tomato-atsuma Power Station: 1,650 MW Coal Power Plant in Hokkaido, Japan

Tomato-atsuma power station is a coal-fired power plant located in Hokkaido, Japan, with a capacity of 1,650 MW. It is owned and operated by Hokkaido Electric Power Co Inc, serving as a key baseload generation asset in the northern region of Japan. The plant 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 facility, it utilizes advanced emission control technologies to meet national standards for SOx, NOx, and particulate matter. The 1,650 MW capacity places it among the larger coal plants in Japan, contributing significantly to the regional power grid. Tomato-atsuma power station plays a critical role in ensuring stable electricity supply for Hokkaido's residential, commercial, and industrial sectors. Its operational status and capacity underscore its importance in Japan's energy mix, though coal-fired generation faces increasing scrutiny under the country's decarbonization goals.

The plant's coal fuel source results in significant CO2 emissions, contributing to Japan's greenhouse gas profile. Its location in Hokkaido, a region with relatively low population density, reduces direct exposure to urban air quality impacts. However, the facility must comply with national emission limits for SOx, NOx, and particulates, and its age and technology level influence its environmental footprint. The plant's capacity of 1,650 MW indicates a substantial resource consumption and waste generation.
