Government and infrastructure The Hawaii Department of Public Safety operates the Waiawa Correctional Facility, a minimum security prison near Waipio. In 2017, the state approved NRG Energy, Inc., to build a 45.9 megawatt Waipio solar farm project north of Costco near Waiawa and H-2 in Waipio. Hawaiian Electric Companies (HECO) will buy electricity from this solar farm at 10.4 cents per kilowatt-hour (kWh) for 22 years. On September 10, 2019, the 45.9 megawatt Waipio Solar developed by Clearway Energy Group began its operation. Originally started by the developer SunEdison, Hawaiian Electric broke its ties to the firm in February 2016 before SunEdison's bankruptcy proceedings. San Francisco-based Clearway's predecessor the NRG Energy's Community Solar division, took over the project at the end of November 2016. On January 22, 2019, the Clearway Energy Group obtained NRG Community Solar's assets. In March 2019, the Public Utilities Commission approved Clearway Energy Group to build a 36 megawatt with 144 megawatt-hour storage solar farm plus battery storage project near Waipio called Waiawa Solar. HECO will buy electricity from this solar-plus-storage project at 10 cents per kilowatt-hour (kWh). The Waiawa Solar project is expected to be completed by Clearway and go online at the end of 2021.
