Sempra Generation intends to install 11 megawatt power storage A123 grid battery system at its wind project site on ‘Ulupalakua Ranch land.

The Auwahi Wind Project was approved by the Maui Planning Commission on Nov. 8, 2011. It will consist of eight wind turbines, each 428 feet tall.

The project will utilize a total of 1,466 acres for a 9 mile power line, a substation, a microwave communication tower, an access road and the turbines themselves. Once finished, it will create enough power to supply up to 21 megawatts, or 10,000 homes.
