The Kaheawa Wind Power Phase II (KWP II) project is located on the island of Maui above the town of Maalaea in the West Maui Mountains. The project was developed by Kaheawa Wind Power II LLC, a division of First Wind Energy and consists of fourteen 1.5 megawatt turbines located below phase one adding an additional 21 megawatts for a total installed capacity of 51 megawatts.
The project features a state-of-the-art battery storage system developed by Xtreme Power. Its Dynamic Power Resource is a utility‐scale battery system that maximizes wind energy efficiency and helps maintain reliable service for the power utility customers. As part of Kaheawa Wind Phase I, First Wind implemented the first-ever Habitat Conservation Plan (HCP) for a utility-scale wind project. In addition to the project’s Environmental Impact Statement, the HCP was developed to ensure a long-term net conservation benefit is provided for three state and federally listed threatened and endangered bird species and the endangered Hawaiian hoary bat.
