The plant was designed to utilize water resources from either the Colorado River via the Central Arizona Project (CAP) aqueduct or from local groundwater. A Zero Liquid Discharge system was required and supplied by Veolia Water’s HPD . The $500mn plant was turned over to a lender consortium called MACH Gen LLC when NEG went bankrupt. Power plant management is by NAES. HGP is connected to the Palo Verde 500kV grid by a 23mi transmission line to the SRP Hassayampa Substation. The plant switchyard and transmission line are operated under a separate contract by Constellation Energy. In 2007/08, the original plant control system was swapped out and replaced by a Siemens T3000 system. Photograph courtesy of
