Sunagawa Daini power station250 MW Coal

Coal

Sunagawa Daini power station, ranking 204th among Japan’s 664 power generation facilities, serves as a notable coal-fired plant with a capacity of 250 MW, operated by Hokkaido Electric Power Co Inc. This facility, commissioned in 1980, represents 0.07% of the national energy capacity, which totals 357,453 MW, a figure predominantly driven by nuclear power. As the 50th largest coal plant in Japan, Sunagawa Daini reflects the challenges and transitions facing thermal energy in a country increasingly focused on sustainable power solutions. Within a 50 km radius, Sunagawa Daini is surrounded by several other energy facilities, including the larger Naie power station (350 MW, coal) and Takisato (57 MW, hydro), creating a competitive energy landscape. Additional nearby plants like Nokanan (30 MW, hydro) and Izamizawa Solar Power Plant (9 MW, solar) highlight the shift towards incorporating diverse energy sources into the regional mix. Despite its coal-based operation, Sunagawa Daini's capacity is crucial for meeting local demands, especially during peak times when renewable resources may not suffice. As Japan continues to navigate its energy future, Sunagawa Daini serves as a reminder of the existing reliance on fossil fuels while underscoring the need for gradual shifts towards cleaner alternatives. The economic implications of this facility's operation contribute significantly to the local economy, yet it also poses environmental challenges that must be addressed as the country moves towards a more sustainable energy framework.
