This is a project specification document prepared by the California Department of Parks and Recreation, Acquisition and Development Division for repairs to the microgrid solar system at Red Rock Canyon State Park in Kern County. The project involves assessment of the existing photovoltaic system, replacement and installation of ground-mounted solar panels, and integration of battery storage components. The scope encompasses complete system evaluation, component replacement, and electrical interconnection work to restore and enhance the microgrid's operational capacity. The work addresses deficiencies in the existing solar infrastructure and includes provisions for fire safety measures, emergency response procedures, and waste disposal protocols for damaged or expired lithium-ion batteries.

The project documentation details comprehensive electrical specifications including photovoltaic wattage requirements of 67 panels totaling 72 panels in the final configuration, battery sizing calculations based on 90% depth of discharge and assumed autonomy periods, and a sequence of operations for normal and emergency conditions. The system incorporates dual inverters, DC and AC feeders, battery management systems, and automated controls for load management and generator integration. Technical requirements specify grounding electrode systems, conduit routing details, 2-hour fire barrier seals at wall penetrations, and compatibility with existing site infrastructure. All materials and installation methods must comply with applicable California Building Code standards, National Electrical Code provisions, and industry standards as referenced in the technical specifications and design drawings provided.
