Nishi Nagoya Diesel Power Plant: 1,190 MW Oil-Fired Facility in Japan

Nishi Nagoya is a large-scale diesel power plant located in Japan, with a capacity of 1,190 megawatts. Operated by Chubu, it is a significant facility in the region's energy infrastructure, contributing to the stability of the local grid. The plant's size places it among the larger oil-fired power stations in 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 an oil-fired facility, it employs technologies to manage emissions of sulfur oxides (SOx), nitrogen oxides (NOx), and particulate matter. Typical Japanese plants of this scale often incorporate advanced emission control systems. Nishi Nagoya serves a critical role in meeting electricity demand in the Chubu region, which includes major industrial and urban centers. Its operation supports grid reliability, especially during peak demand periods. The plant's environmental impact is managed through compliance with national standards, and it contributes to Japan's energy security by utilizing oil, a fuel source that can be stored and dispatched flexibly.

The plant's oil-fired operation results in higher CO2 emissions per MWh compared to natural gas or nuclear plants. Its location near populated areas requires strict adherence to air quality standards. The facility's age and technology level influence its efficiency and emission profile, with older subcritical units being less efficient than modern supercritical or combined-cycle plants. Proximity to the coast may also affect cooling water usage and thermal discharge.
