Sempra U.S. Gas & Power and BP Wind Energy have completed the 21 MW Auwahi Wind facility. The project includes eight new wind turbines on the southeast ridge of Maui's Haleakala volcano.
The power from Auwahi Wind has been sold to Maui Electric Company (MECO) under a 20-year contract. The project features a 10 MW battery capable of storing 4.4 MW-hours of power. Energy from the battery will help regulate and sustain power to the MECO grid during light wind conditions.
Construction of the wind farm on Ulupalakua Ranch began in March 2012 and involved more than 180 workers. Auwahi Wind will employ four full-time employees.
