Background
The Tomatouatsuma coal-fired plant is owned by Hokkaido Power Company.[2] 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.[3] 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.[4] 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.[5]
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.[6]
In May 2026, Hokkaido Electric Power won a bid in the FY2025 Long-Term Decarbonized Power Source Auction for the ammonia co-firing conversion of Unit 4. Operations were slated for FY2032.[7]
