A small fire broke out Friday inside the structure housing a 10 MWh battery-based energy-storage system at the new Kahuku wind farm in Oahu, Hawaii, the Honolulu Star-Advertiser reports.
The blaze had been extinguished by the time firefighters arrived on the scene, at around 6 p.m. Friday night. Hazardous-materials experts assessed the damages on Saturday and determined that the site was safe.
The project was developed by Massachusetts-based First Wind, which hopes to have the facility back online as soon as possible.
‘First Wind reported to Honolulu fire officials that there was smoke at our Kahuku Wind facility, in the battery energy-storage building,’ said First Wind spokesperson John Lamontagne in a statement. ‘The cause of the fire is not known and is being investigated.’
The energy-storage system, which was manufactured by Texas-based Xtreme Power, helps balance the output variability of the 30 MW wind farm, which was dedicated late last month.
