Background
The Tomatouatsuma coal-fired plant is owned by Hokkaido Power Company.[1] It produces 1,650MW from its three operating Units. Unit 1 (350MW) was commissioned in 1980; Unit 2 (600MW) was commissioned in 1985; and Unit 4 (700MW) was commissioned in 2002.[2] Unit 3 (85MW) was commissioned in 1985 and retired in 2005.
On June 11, 2023, Unit 2 was shut down for a day due to a 6.2 magnitude offshore earthquake.[3] Later in June 2023, it was reported that Hokkaidō Electric expected to restart Unit 4 in August after having been shut down five months earlier when cracked steam pipes were discovered.[4]
In July 2024, a long-term decarbonization roadmap was released, including information on ammonia and hydrogen co-firing at coal plants in Japan. According to the roadmap, Tomatouatsuma power station Unit 4 would co-fire 20% ammonia by FY2030.[5]
