AES Lawai Solar (AES), a subsidiary of The AES Corporation, built, owns, and operates a 20 megawatt alternating current (MWac) / 28 MW direct current (MWdc) 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 provides 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. In addition to providing grid stability and support for increased renewables, this project is estimated to increase KIUC's renewable portfolio by 11% and displace 3.7 millions gallons of fuel annually. Sheep are being used to control vegetation growth onsite, which provides an example of how energy and agriculture can compliment each other. When it became commercially operational in April 2019, this facility was the largest PV + BESS peaker power plant in the world according to KIUC.
