First Wind completes Kaheawa Wind II project

Located above Ma'alaea harbor in West Maui, Kaheawa Wind II features a battery energy storage system to assist in meeting performance standards and smoothing fluctuations in wind energy output

Kahului, Hawaii, July 5, 2012 — First Wind, an independent U.S.-based wind energy company, announced that construction of the 21 MW Kaheawa Wind II project has been completed and commercial operations have begun.

Located above Ma'alaea harbor in West Maui, Kaheawa Wind II features a battery energy storage system to assist in meeting performance standards and smoothing fluctuations in wind energy output.

Early last year, the Hawaii Public Utilities Commission approved a power purchase agreement between Kaheawa Wind II and Maui Electric Co. to sell as-available renewable energy to Maui Electric at pre-determined prices over a 20-year term.

The project expansion further advances the Hawaii Clean Energy Initiative, which aims to have 70 percent of Hawaii's energy come from clean, renewable sources by 2030.

Adjacent to the site of its Kaheawa Wind I project, which achieved commercial operations in June 2006, the Kaheawa Wind II project is going online almost exactly six years later. At 51 MW, the combined output of Kaheawa Wind I and II has the capacity to generate enough energy to power up to 18,700 Maui homes annually.

RMT, which began construction on Kaheawa Wind II in 2011, oversaw all civil and electrical infrastructure including a 34.5/69-kV substation, 34.5 kV electrical collection system, and interconnection to the 69 kV Maui Electric Co. transmission line.
