The eight wind turbines are situated along the slopes of the Haleakala volcano and generate enough electricity to power 10,000 local homes.
More than 180 jobs were created during the project construction. Four full-time employees operate the wind farm today.
Hawaii has a renewable energy portfolio standard that requires it to derive 40 percent of its power from renewable sources by 2030.
The 21-MW Auwahi Wind facility represents BP and Sempra’s first alternative energy venture in Hawaii. Maui has a total installed capacity of 72 MW of wind energy.
The project also incorporates an 11-MW/4.4-MWh-hour grid battery system. At its peak, this system is capable of 11 MW sustained for about 25 minutes. The battery system’s energy helps regulate and sustain power to Maui Electric Co.’s grid during light wind conditions.
