Description:
AES Lawai Solar, a subsidiary of The AES Corporation, built, owns, and operates a 20 megawatt alternating current (MWac) / 28 MW direct current solar photovoltaic system with a 100 megawatt-hour (MWh) battery energy storage system (BESS) on approximately 194 acres of land leased from Alexander & Baldwin (McBryde Sugar Co.) in the Lawai area. The project will provide power to the Kauai Island Utility Cooperative (KIUC) at a contracted price of $0.11080 / kilowatt-hour (kWh) for 25 years including monetized tax incentives according to the power purchase agreement approved by the Hawaii Public Utilities Commission in July 2017. AES is utilizing SunPower's solar panels and innovative Oasis Power Plant platform increase facility efficiency and performance. The project BESS consists of 13,000 Samsung SDI lithium-ion battery modules. KIUC will have the discretion and ability to dispatch power from this facility in the preferred manner to support KIUC's fluctuating and peak power delivery demands. Construction broke ground in February 2018 and the facility became operational in December 2018. In addition to providing grid stability and support for increased renewables, this project is estimated to provide approximately 11% of Kauai's energy needs and displace 3.7 millions gallons of fuel annually.
