AES DE, SunPower partner for innovative solar plus storage plant in Kaua‛i


AES Distributed Energy and SunPower announced that a SunPower Oasis  Power Plant platform with an innovative solar plus storage facility is under development by AES DE on the Hawaiian island of Kaua‛i .

AES DE will construct a 28-megawatt SunPower Oasis system at the site, as well as a 20-megawatt five-hour duration energy storage system.

AES DE expects the project will be the largest solar-plus-utility-scale-battery system in the state of Hawai‛i, and one of the largest solar electricity storage systems in the world. The power generated and stored at the plant will serve customers of the Kaua‛i Island Utility Cooperative (KIUC).

“As the result of a competitive bid process, SunPower Oasis Power Plant technology was selected to optimize the cost-competitive solar power generated for KIUC customers at this facility,” said Woody Rubin, president of AES DE.

The SunPower Oasis platform is a fully integrated power plant solution designed to streamline construction, reduce operations and maintenance costs, and maximize value for customers, the company said.

SunPower E-Series solar panels that will be mounted on the Oasis solar trackers at the Kaua‛i facility produce 30 percent more energy than conventional solar panels in the first year of operation, according to SunPower.

AES DE will be the long-term owner and operator of the project, which is expected to be operational by the end of 2018.
