State-run firm Korea Water Resources (K-water) hopes to build 1.2GW of floating PV by 2022. “But there are many restrictions, including environmental obstacles,” says Ho-yeon Han, director of green energy and resources at K-water. “Our plans could change.”

The company is planning South Korea’s second major floating PV project, an 8MW installation at two dams in Chungcheongnam province and Chungcheongbuk province, both south of Seoul.
