LAWAI, KAUA`I (Ben Caxton) — From sugar canes to solar panels land on the south side of Kaua`i has passed the halfway point to becoming Hawai`i’s largest solar electrical generation plant. The Kauai Island Utility Cooperative showed off the new facility in Lawai yesterday. Besides directly feeding Kaua`i customers electricity from 28-megawatts worth of solar panels, the plant is unique because it will also feature a 100-megawatt hour five-hour duration energy storage system. That means long after the sun goes down its energy will still be providing power to up to 40% of island customers. KIUC has a goal of providing 70% of it’s electricity from renewable sources by 2030.
