Why it matters
- The 10th-largest coal-fired power station in Japan by capacity (of 78 operating, under-construction and planned coal facilities tracked).
- If completed, it would add 1.95 GW to Japan's coal fleet — equivalent to 3.7% of today's operating coal capacity.
- Coal-fired units are typically run as baseload or mid-merit plants and are the most carbon-intensive form of power generation, which makes their retirement schedules a key indicator of national transition plans.
