First Wind LLC said it has temporarily idled the turbines at its Kahuku wind energy project while it works on the battery storage system.
The 12 wind turbines were shut down on May 22 and are expected to be brought back online in stages starting later this week, company spokesman John Lamontagne said in an email from the company’s headquarters in Massachusetts.
“We are conducting a diligent and thorough review of the operating issues for the battery facility at the Kahuku project. During that time, the project is offline,” he said.
The 30-megawatt project — Oahu’s only commercial-scale wind farm — began feeding electricity into Hawaiian Electric Co.’s grid in March. The turbines produce enough energy to power about 7,700 homes, according to First Wind. First Wind sells the electricity to HECO at a fixed price of 19.9 cents per kilowatt-hour under a 20-year purchase power agreement.
