The Kaheawa Wind II project features an innovative battery storage system that maximizes wind energy efficiency by the smoothing fluctuations in wind energy output.

Going online six years the first phase of the project was operationalized, the Kaheawa II takes the combined capacity of both phases to 51MW.

The energy produced at the two phases of Kaheawa project is enough to power around 18,700 Maui homes annually. And reduces carbon emissions by 126,000mt.

First Wind CEO Paul Gaynor said the expansion of Kaheawa Wind project supports the state’s aggressive renewable energy goals by providing an additional source of cost-competitive and clean electricity to the residents and businesses of Maui.

The Hawaii Public Utilities Commission has approved a power purchase agreement (PPA) between Kaheawa Wind II and Maui Electric Company to sell renewable energy to Maui Electric over a 20-year term.
