Sempra Generation has signed a 20-year contract to sell wind energy to Maui Electric Co. from Sempra’s 21-megawatt Auwahi Wind project on the Ulupalakua Ranch in the southeastern region of Maui.
Sempra said it expects to begin construction on Auwahi Wind in early 2012, creating about 150 local construction jobs at peak and about five positions to operate the facility. The project is currently undergoing an environmental review by Maui County, and state and federal agencies.
When fully operational in late 2012, Auwahi Wind will be capable of generating enough energy to power 10,000 typical Maui homes, the company said.
The project will have a battery storage unit could store as much as 12 megawatt-hours of wind energy generated by the project’s wind turbines. The stored power will help to smooth the fluctuations normally associated with wind power.
The contract between Maui Electric Company and Sempra Generation is subject to approval by the Hawaii Public Utilities Commission.
Maui already has 51 megawatts of generating capacity from the Kaheawa I and Kaheawa II wind projects developed by First Wind LLC on a ridge above Maalaea.
