P-1238, CONSTRUCTION OF GRID STABILITY AND RESILIENCY 10 MW, BATTERY ENERGY STORAGE SYSTEMS, MARINE CORPS AIR GROUND COMBAT CENTER (MCAGCC), TWENTYNINE PALMS, CA

This acquisition will result in an unrestricted full and open Firm-Fixed Price (FFP) Design-Build

contract for the design and construction of a total of 8.5 MW(5.5MW at cogeneration site 1 and 3.0MW at cogeneration site 2) 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.
