HEPCO has coal-fired power stations at three locations: Sunagawa City, Naie Town and Atsuma Town (Tomakomai City), and these three stations produce close to 1 million tons of coal ash each year. Much of this coal ash is used for concrete admixture, cement raw material, mine reclamation, and road base material. Advances are also being made to expand the use of coal ash in the civil engineering, construction, and agriculture sectors, as illustrated below.
