The Hiilangaay Hydroelectric Project (“Hiilangaay” or the “Project”) is a 5-megawatt hydroelectric resource currently under construction on Prince of Wales Island (POW), Alaska, approximately ten miles east of Hydaburg. The objective of the Project is to interconnect with the existing transmission grid on Prince of Wales Island, increasing the hydroelectric generation capability by 5 MW, eliminating the need for diesel generation, increasing the reliability of the electrical system, and allowing the interconnected portion of the island to have 100 percent renewable energy generation. Pre-construction activities including construction planning, permit coordination and compliance, and final design have made it possible to move forward with construction of the Hiilangaay Project. Despite repeated delays to the schedule, persistence and long-term planning will culminate in the construction of the Project, and make Prince of Wales Island independent of diesel-fueled energy
