Renovation of a military facility in Twentynine Palms, California. Completed plans call for the renovation of a military facility.

This acquisition will result in an unrestricted full and open Firm-Fixed Price (FFP) Design-Build contract for the design and construction of 10 MW (6.5 MW Base Item and 4MW in option items) of Battery Energy Storage Systems (BESS) at two (2) locations on MCAGCC, Twentynine Palms, California (P-1238). Each of the estimated 30 BESS (each of which will include high energy density batteries, bidirectional inverters, and the associated controls) will be a standalone modular packaged unit connected to one or more solar photovoltaic (PV) arrays. The BESS will be connected to the solar PV systems for clean energy charging as well as to the installation's electric distribution system for utility power or on-site cogeneration system charging. The BESS will be tied into the installation's microgrid (being built via project P-1232) so the battery energy can be discharged to level solar PV variability and stabilize the grid (electrical distribution system reliability), provide power to support black-start and islanding events (energy resilience), and reduce energy costs during peak demand/energy pricing periods (energy management/efficiency). Also, the BESS controls will be accredited to ensure the energy systems remain cyber secure. The goal for this project is to integrate BESS into an electrical distribution microgrid on MCAGCC. The project installs and fully permits new BESS capable of parallel operation, each located in proximity to existing PV systems.
