Korea Zinc will source 11 gigawatt-hours of renewable electricity annually from solar plants in Gangwon State, Gyeonggi Province and North Gyeongsang Province under a 20-year contract with Hanwha Shinhan Terawatt Hour starting in December. The price will remain unchanged throughout the term, helping the company pursue lower medium- to long-term electricity costs while cutting emissions. Korea Zinc holds a 33.3% stake in Hanwha Shinhan Terawatt Hour and operates renewable-energy projects in Australia, including solar and wind assets. It also plans to begin operating SunHQ, a green hydrogen (hydrogen made using renewable electricity) facility, this year and expand renewable-energy use at its Onsan refinery.
