A new solar development that would combine 28 MW of solar panels with a 20-MW five-hour energy storage system is set for the Hawaiian island of Kaua’i.
The development, planned for former sugar land between Lawa’I and Koloa on Kaua’I’s south shore, will be developed by AES Distributed Energy. Kaua’i Island Utility Cooperative will purchase power generated.
When finished in 2018, the solar and battery system will provide 11 percent of the island’s energy generation and be one of the largest in the world.
“The project delivers power to the island’s electrical grid at significantly less than the current cost of oil-fired power and should help stabilize and even reduce electric rates to KIUC’s members,” said David Bissell, president and CEO of KIUC. “It is remarkable that we are able to obtain fixed pricing for dispatchable solar based renewable energy, backed by a significant battery system, at about half the cost of what a basic direct to grid solar project cost a few years ago.”
The utility estimated energy from the project will be sold to customers at 11 cents per kWh.
AES will own and operate the project.
