The Department of the Navy, Naval Facilities Engineering Systems Command, NAVFAC Southwest, has a requirement for Project P-1238 Construction of Grid Stability & Resiliency 10 MW Battery Energy Storage, Various Buildings at Marine Corps Air Ground Combat Center, Twentynine Palms, California.

N/A

The Contractor shall provide:

• 30 BESSs (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 BESSs 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 BESSs 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.
• Integrate BESSs into an electrical distribution microgrid on MCAGCC. The project installs and fully permits new BESSs capable of parallel operation, each located in proximity to existing PV systems. Interested respondents must be able to:
  • Demonstrate experience with DoD’s Risk Management Framework (RMF) and Authority to Operate (ATO) processes. Demonstrate experience collecting the information needed by the Government to complete these processes.
  • Demonstrate experience with DoD’s cyber and physical security requirements. Ensure cybersecurity of the MCAGCC energy system by accrediting the BESS controls which will be integrated into the current MCAGCC microgrid system.
  • Integrate 10 to 30 BESSs into existing medium-voltage distribution system (34.5 and 12.47 kV). Evaluate each proposed BESS location for integration with existing PV inverters, transformers, switches, breaker panels, as well as evaluating BESS to be combined into larger systems where appropriate. The BESS must be lithium-ion chemistry. Demonstrate knowledge of the most recent technological advances in Li-ion batteries that improve stability and safety, and maximize charge-discharge cycles while minimizing capacity degradation.
  • Design and install BESSs to operate with existing controls, generators, and loads.
  • Modify existing microgrid controls as needed. Demonstrate experience with advanced controls and programming as related to microgrid, PV, Combined Heat and Power (CHP) and BESS in grid-connected and island mode.
  • Perform associated electrical studies for grid-tied and microgrid system equipment that are owned and operated by the MCAGCC.
    • Update existing electrical model of MCAGCC and add new devices as needed (model is currently being updated to reflect present MCAGCC system).
    • Power flow analysis of various scenarios to determine if changes to existing systems will be required.
    • Model various advanced microgrid scenarios to fully leverage existing resources such as providing ancillary services.
    • Evaluate protective devices and settings to operate with new distributed BESS.
  • Develop control and communication needs based on expected BESS use cases.
  • Design and install network infrastructure (fiber optic, routers, switches, servers, equipment racks, uninterruptible power supplies etc.) and graphical user interfaces and human-machine interfaces as needed for BESS Supervisory Control and Data Acquisition (SCADA) system. Communication systems may include fiber optic-based network, existing radio frequency system or other available communications systems.
  • Integrate BESSs and network infrastructure with existing controls/SCADA.
    • The BESS and PV will communicate on the energy management control system network, not the microgrid network.
    • Provide remote on-off functionality for the BESS (and potentially include similar control to local PV systems).
    • Record total PV production, and BESS power, and energy for each charge and discharge cycle to an existing central data historian for each distributed BESS. Demonstrate experience modifying an existing data historian to include new fields.
  • Demonstrate experience with developing or modifying associated interconnection agreements (modified or new agreements would be completed by the contractor and submitted to Southern California Edison [SCE] by MCAGCC personnel).
  • Assess if ancillary services can or need to be provided: power factor correction, voltage and frequency regulation, inertia response. Coordination with SCE engineering likely required as California Rule 21 requires smart inverter installations.
  • Demonstrate experience commissioning distributed BESS and control systems in microgrid systems. Troubleshoot and resolve any operational issues.
