Oahu, Hawaii, March 25, 2011 — Xtreme Power, a manufacturer of large-scale energy storage and power systems, commissioned a 15 MW system on First Wind's 30 MW Kahuku Wind project during a formal dedication ceremony on Oahu.
At the Kahuku site on the North Shore of Oahu, the DPR digitally smoothes the wind farm's output to about 1 MW per minute by rapidly absorbing or releasing power as needed so that Hawaiian Electric Co.'s grid system and local customers are shielded from disturbances due to varying winds at the Kahuku Wind farm.
The site is unique in its transmission challenges that required a storage solution in order to avoid costly transmission upgrades and project delays. Xtreme Power also designed the system with the ability to double its storage capabilities in the same square footage, should First Wind require additional capacity in the future.
The Kahuku project is one of three collaborations between Xtreme Power and First Wind. Dynamic Power Resources are also operating on First Wind's Kaheawa Wind Power wind farm and will be integral to the Kaheawa Wind Power II wind farm, both on the Island of Maui.
