URL More about Kaheawa Wind Power Project II - Younicos
On the island of Maui, a 10 MW / 45 minute Xtreme Power DPR was integrated with the 21 MW Kaheawa Wind Power II project, built by First Wind, to provide utility-scale power storage and management. The DPR is intended to address the issue of curtailment as renewable energy penetration rates increase on Maui; in addition, it will provide ramp control, responsive reserves, frequency regulation, and automatic generation control (AGC) for the Maui Electric Co. (MECO). In April 2014, Younicos acquired the assets of the former Xtreme Power.
