Corporate history

Kauaʻi Electric was incorporated in 1905 as a subsidiary of McBryde Sugar in order to construct a 2.4 MW hydroelectric plant on the Wainiha River. Kauaʻi Electric merged with Lihue Plantation's Waiahi Electric Company early in the 1950s. Kauaʻi Electric became a division of Citizens Utilities Company in 1969. In the late 1990s, Citizens Utilities announced its intentions to divest from the electric utility business and a group of business leaders from Kauaʻi joined to found the Kauaʻi Island Utility Cooperative in 1999. KIUC purchased Kauaʻi Electric Company on 1 November 2002 for $215 million. In December 2009, KIUC participated in hearings regarding its plan to minimize the effects its operations have on three endangered Hawaiian birds, the ʻuaʻu, the ʻaʻo, and the
