In 2017, the state approved NRG Energy, Inc., to build a 49 megawatt solar farm project near Waialua called Kawailoa Solar. HECO will buy electricity from this solar farm at 11 cents per kilowatt-hour (kWh) for 22 years. On September 10, 2019, the 49 megawatt Kawailoa 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.
Hawaii State Public Library System operates the Waialua Library.
Many of the current families living in Waialua are the results of agricultural industry which began in the early 20th century. There was an increased demand for workers as the industry grew, resulting in workers being brought in from China, Portugal, Japan, Korea, Puerto Rico, the Philippines and other areas. Upon arriving in Hawaii, many of these workers were assigned to work in the sugarcane plantations in Waialua. During the late 1980s and into the 1990s, the sugar production decreased as increasing labor and production costs caused producers to move overseas. Many of the families brought to Waialua during the sugar rush remained here and many of their descendants reside there today.
