95% of daytime energy met by solar in Kauai – now extending into the eve with Tesla batteries

According to Pacific Business News, Tesla Energy batteries will be used for a SolarCity solar farm and energy storage system which is being developed for Kauai Island Utility Cooperative (KIUC) in Kaua’i, Hawaiʻi.

As much as 95% of daytime demand on Kauai is met by solar at present but KIUC has targeted extending this number into the evening hours. When all is said and done, SolarCity’s grid-connected project will provide the 52 MWh utility-scale battery facility, built to distribute up to 13 MW of solar power.

“That a small co-op on Kaua‘i can become a world and national leader in energy transformation in such a brief time is something all of our members can be proud of and celebrate,” said KIUC president and CEO David Bissell.  Bissell has said, “No other utility in the US has a higher percentage of large-scale solar on its grid than KIUC.”

The Tesla Energy batteries will supply a 52 MWh utility-scale energy storage system in order to help KIUC meet evening peak demand, which typically occurs between 5:00 pm and 10:00 pm. The storage system will be located at a 12 MW solar farm.
