AES Distributed Energy, Inc. (AES DE, Boulder, CO, U.S.) and Kauaʻi Island Utility Cooperative (KIUC) on January 10th, 2017 announced a power purchase agreement (PPA) for an innovative plant that will provide solar power together with the benefits of battery-based energy storage for optimal balancing of generation with peak demand.

The project consists of a 28 MW solar photovoltaic (PV) system and a 20 MW five-hour duration energy storage system (ESS).

The system will be located on former sugar land between Lāwaʻi and Kōloa on Kauaʻi's south shore. It will be the largest solar-plus-utility-scale-battery system in the state of Hawaiʻi and one of the biggest storage systems in the world.

“Energy from the project will be priced at 11 cents per kWh and will provide 11 percent of Kauaʻi’s electric generation, increasing KIUC’s renewable sourced generation to well over 50 percent,” said KIUC’s President and Chief Executive Officer, David Bissell.

Bissell estimates that the project will reduce KIUC’s fossil fuel usage by over 3.7 million gallons yearly.

AES DE will be the long-term owner and operator of the ESS project. The project is pending state and local regulatory approvals. If approved, the project is expected to come on-line by late 2018.
