First Wind says that it has completed construction of the 21 MW Kaheawa Wind II project and begun commercial operations. 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, First Wind says.

Early last year, the Hawaii Public Utilities Commission approved a 20-year power purchase agreement between Kaheawa Wind II and MECO. The project expansion further advances the Hawaii Clean Energy Initiative, which aims to have 70% of Hawaii's energy come from renewable sources by 2030, the developer says.

RMT, which began construction on Kaheawa Wind II in 2011, oversaw all civil and electrical infrastructure engineering, including a 34.5 kV electrical collection system, and interconnection to the 69 kV Maui Electric Company (MECO) transmission line.

The Kaheawa II project also features a state-of-the-art battery storage system developed by Austin, Texas-based Xtreme Power. Its dynamic power resource is a utility-scale battery system that assists in meeting stringent performance standards and smoothing fluctuations in wind energy output. The system will maximize wind energy efficiency and will help MECO maintain service for its customers, First Wind notes.
