SolarCity to use Tesla batteries for Kauai utility solar storage project

Posted on Feb 17, 2016 in Energy Storage, Headlines, Kauai, Pacific Business News

(Pacific Business News)  Tesla Energy, a division of California serial entrepreneur Elon Musk’s Tesla Motors, will supply the batteries for a unique solar farm and energy storage system being developed for Kauai Island Utility Cooperative, the co-op said Tuesday.

SolarCity, whose chairman is Musk, is building the system and selected Telsa Energy for the planned project, which is believed to be the first utility-scale system in the United States that will be able to provide electricity generated from solar energy on demand, even at night.

The 52-megawatt-hour Tesla Powerpack lithium-ion battery storage system is expected to provide up to 13 megawatts of power onto the grid.

Under the terms of the 20-year contract that was announced in September, KIUC will pay SolarCity 14.5 cents per kilowatt-hour, only slightly more than the cost of energy from KIUC’s two existing 12-megawatt solar farms whose output is available only during the day.

The project will be developed on 50 acres of land owned by Grove Farm Co. near KIUC’s Kapaia power station off Maalo Road north of Lihue.

It already has received most of its required state and county approvals and is now awaiting approval from the Hawaii Public Utilities Commission.

Construction is scheduled to start by April and the goal is to have it be operational by the end of the year.
