An updated interconnection requirementsstudy was conducted and determined that a new technology could replace the needfor a battery system at the site.

The new Dynamic Volt-AmpReactive (DVAR) system is a cost-effective way to provide continuous voltageregulation. The recently installed technology also improves voltage stabilityon utility Hawaiian Electric Company’s (HECO) grid, as well as meetsinterconnection requirements, according to First Wind.

The Kahuku Wind project’s 12wind turbines have been fully maintained since the shutdown in 2012 and testingof turbines and new DVAR technology began last September.
