Auwahi Wind Project to install battery power storage system

Sempra Generation has announced the intended installation of an 11 megawatt power storage A123 grid battery system at its wind project site on 'Ulupalakua Ranch land. The completed project will help to stabilize the power being put into the island's power grid.

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.

"We believe that wind-rich locations like Hawai'i represent a significant opportunity for energy storage, especially as project developers and utilities continue to understand that storage has the capability to help maximize production and reduce the challenges associated with the variability of wind power generation," said Robert Johnson, vice president of the Energy Solutions Group at A123.

"This will help Maui Electric manage the grid and deliver a smooth amount of energy for the project," said Sempra Spokesperson Scott Crider.
