Heber 1 Parasitic Solar Energy Project

The Heber 1 Parasitic Solar Energy Project involves the development of a 20 megawatt solar energy facility and an interconnecting medium voltage cable line in unincorporated Imperial County, California. The facility is designed as a behind-the-meter system to provide parasitic load power to offset the auxiliary load of the existing Heber 1 Geothermal Plant, meaning it will not connect to or generate power for the transmission grid. The project will be located on approximately 121.44 acres of land, including a 106.19-acre solar field and a cable route of approximately 15.25 acres. Construction is anticipated to take 16 to 19 months starting in late 2025, spanning site preparation, project construction, and switch development and interconnection. The project is subject to a Conditional Use Permit and comprehensive environmental review under the California Environmental Quality Act. Key requirements include compliance with fugitive dust regulations, the implementation of a Water Quality Management Plan, and the execution of a Stormwater Pollution Prevention Plan. Extensive biological and cultural assessments have been conducted, including surveys for western burrowing owls, bat acoustics, and avian populations, as well as tribal cultural resource consultations. The project requires the use of approved botanical field surveyors and the implementation of a mandatory education program for all construction personnel. Additionally, the project applicant must participate in the Imperial County Public Benefit Program and enter into a public benefit agreement to cover associated costs and fees.
