January 9 (Renewables Now) - US power company AES Corp (NYSE:AES) and Kaua’i Island Utility Co-Operative (KIUC) inaugurated on Tuesday a 28-MW solar plant on the island of Kaua’i, the state of Hawaii, with a 100-MWh five-hour duration energy storage system.

AES says that the so-called Lawa’i solar and energy storage project is now the largest operational solar and storage system globally and it will deliver about 11% of Kaua’i’s power, while eliminating the use of some 3.7 million gallons of diesel annually.

Meanwhile, AES Distributed Energy (AES DE) is building a 19.3-MW solar plus 70-MWh battery storage facility for KIUC on leased land from the US Department of Defense within the Pacific Missile Range Facility – Barking Sands (PMRF) Naval Base. The parent company noted that solar-plus-storage projects make up roughly half of AES DE’s under construction projects, totalling 128 MW, and over 250 MW of later stage developments.

KIUC said separately that its renewable portfolio has now grown from 8% in 2010 to more than 50% at the end of 2018. The company is buying the output of Lawa’i solar park under a 25-year power purchase agreement (PPA) at USD 0.11 (EUR 0.096) per kWh.

(USD 1.0 = EUR 0.871)
