• Abstract:
  Biddeford Saco Old Orchard Transit (BSOOB Transit) is advancing the integration of zero-emission vehicle (ZEV) technologies by implementing a resilient microgrid to support its fleet electrification goals. The proposed microgrid will provide clean energy and backup power for BSOOB's heavy-duty electric buses, ensuring uninterrupted transit operations during grid outages. The microgrid includes new electronic breakers that function as control switches instead of traditional automatic transfer switches (ATS). It advances the state of the art by integrating real-time smart grid controls, predictive energy management, and multi-source backup power into a transit-specific, scalable microgrid model. BSOOB Transit has brought on Willdan as a project partner who has already completed the initial assessment, feasibility and preliminary design of the microgrid. Willdan is a leading provider of energy solutions and services and will ensure successful project execution through their extensive expertise in microgrid design, distributed energy resources, and advanced energy management systems. Their technical excellence will be instrumental in developing a resilient and efficient clean energy solution for transit electrification. BSOOB also will work closely with regional entities such as the Governor’s Energy Office, Central Maine Power, and Efficiency Maine for additional support to implement the microgrid.
  
  This microgrid will enable BSOOB to maintain transit operations even during prolonged power outages, a critical feature given Maine’s increasing extreme weather events. As transit agencies across the country electrify their fleets, they are still required to provide reliable service, and thus their charging strategies must be resilient to outages. Microgrids, which are still in their infancy, are one way to provide resilient, low-carbon power. Key Components of the Microgrid:
  
  • 450 kW Solar PV System – Renewable energy generation • 653 kW / 2,611 kWh Battery Energy Storage System (BESS) – Provides carbon free long duration energy storage during blue sky weather and peak load management
  
  • 625 kW Natural Gas Generator – Low-carbon backup power for extended winter outages
  
  • Advanced Microgrid Controller & Smart Circuit Breakers – Utilizes advanced hardware and software technology to optimize energy dispatch and ensure system reliability.
  
  • Electric Vehicle Charging Infrastructure (EVCS) – Supports up to eight heavy duty transit buses simultaneously
