Xtreme Power deploys energy storage system for 12MW Kauai Island Utility Cooperative solar farm. Islands represent a unique energy storage market because of their great need to mitigate reliance on diesel fuel. For Hawaii, projects like KIUC IV reduce the total cost of producing power.

Xtreme Power, an integrated power management and energy storage solutions provider, has announced a new project in Hawaii with the Kauai Island Utility Cooperative (KIUC). The KIUC IV project will be installed on a new 12MW solar farm, with commissioning scheduled for May 2014.

The project is Xtreme Power’s eighth system in Hawaii. KIUC already has 4.5MW of Xtreme Power systems in operation in Kauai, and the fourth collaboration will use lithium ion batteries. The company will deploy an energy storage system — 2MW, 15 minutes — to provide ramp rate control and fast frequency response to help integrate the 12MW solar farm.

“We’re thrilled to announce yet another project commissioning in Hawaii where the commitment to greening the power grids is inspiring,” said Alan Gotcher, Chief Executive Officer of Xtreme Power. “We’re proud to be a partner for utilities on the island, and to build upon our relationship with the community.”

According to Xtreme Power, islands represent a unique energy storage market because of their great need to mitigate reliance on diesel fuel. For Hawaii, projects such as KIUC IV reduce the total cost of producing power. 

“KIUC is pleased to be working with Xtreme Power on our fourth battery system to help deliver the promise of clean, affordable green energy,” said John Cox, engineering manager of KIUC. “[The energy storage system] preserves grid reliability while supporting continued renewable integration efforts in accordance with KIUC’s strategic goals.”

According to the utility, by 2015, half of Kauai’s daytime energy needs will be met by solar PV. That would be the highest percentage of solar PV on an electrical grid of any utility in the U.S.
