Xtreme Power is installing an energy storage and management system for a 12 MW solar farm under development for the Kauai Island Utility Cooperative (KIUC) in Hawaii. Xtreme Power says the installation will include its RAMP Series energy storage system (ESS).
The cooperative broke ground on the solar facility this month. SolarCity is building the system, which will include 45,000 solar panels. It is scheduled to be completed in May 2014. The cooperative says that the $40 million project is expected to supply 5% of the island's power and be the largest solar plant in Hawaii. KIUC says it financed the project through the National Rural Utilities Cooperative Finance Corp., which is also a cooperative.
According to Xtreme Power, the 2 MW (500 kWh) RAMP Series ESS will provide ramp rate control and fast frequency response for the KIUC solar facility, enabling its integration into the electric grid. The system will join an existing 1.5 MW Xtreme Power storage unit at KIUC's Koloa substation.
