Atsumi Diesel Power Plant: 1,900 MW Oil-Fired Facility in Japan

Atsumi is a large-scale diesel power plant located in Japan, with a capacity of 1,900 MW. Operated by Chubu, the facility is a significant contributor to the region's electricity supply, utilizing oil as its primary fuel source. The plant's operational status is active, supporting grid stability and meeting peak demand. Japan's power generation sector is characterized by a diverse mix of thermal, nuclear, and renewable sources. Atsumi operates under Japan's stringent environmental regulations, including the Air Pollution Control Act and the Act on Promotion of Global Warming Countermeasures. The plant's technology and age influence its efficiency and emissions profile, with older subcritical units typically having higher CO2 and SOx emissions compared to modern combined-cycle gas turbines. The facility's location near populated areas underscores the importance of emission controls and monitoring. As part of Chubu's portfolio, Atsumi contributes to the regional grid's reliability, serving industrial and residential consumers. Its capacity places it among the larger oil-fired plants in Japan, highlighting its strategic role in the energy landscape.

Atsumi's oil-fired operation results in significant CO2, SOx, and NOx emissions, contributing to Japan's greenhouse gas inventory. Proximity to populated areas necessitates robust emission control technologies to comply with national air quality standards. The plant's age and technology (likely subcritical) may result in lower efficiency and higher per-MWh emissions compared to newer facilities. Japan's regulatory framework, including the Act on Promotion of Global Warming Countermeasures, drives gradual emission reductions, though oil-fired plants face increasing pressure to decarbonize.
