Electric clean energy production technologies, will enable the County to provide a sustainable, resilient, and reliable energy supply for bus charging and site operations. The project will include the following: bus charging, incorporating » 2 Megawatts (MW) of solar photovoltaic canopies that will provide electrical power to the buses and to the battery storage systems » 4.3 Megawatt Hours (MWH) battery storage » 2 MW of natural gas generation » Microgrid controller This program is a public-private-partnership or P3, an agreement with AlphaStruxure , a leader in Energy as a Service (EaaS) solutions. The project will enable at least 44 buses in the Ride On Montgomery County’s transit fleet to transition from diesel to electric power. This advances the County’s goal to reach net zero carbon emissions by 2035, reducing lifetime emissions by over 155,000 tons, while delivering resilience to climate events and power outages. The Brookville Smart Energy Bus Depot is a first- of-its-kind integration of microgrid and EV charging infrastructure, delivering sustainability, reliability, and resilience for the County’s public transportation system. AlphaStruxure, a joint venture of Schneider Electric and the Carlyle Global Infrastructure Opportunity Fund , designed, built, financed, and has owned and operated the project to enable Ride On’s growing electric bus fleet.
Completed in late October 2022, the project will deliver the following benefits and outcomes: Bus Electrification: Enabling the County’s transition from fossil fuel buses to electric buses with a customized energy and infrastructure solution. Environmental Sustainability: 62 percent carbon emissions reduction with electric buses powered by the microgrid and lifetime greenhouse gas benefit of over 155,000 tons. Climate Resilience and Operational Reliability: Ensures uninterrupted bus services during any long- term power outages caused by severe weather as well as any short-term disturbances or perturbations of the utility grid. Flexible Fleet Operations: Avoidance of utility demand charges and time-of-use tariffs provides fleet operations with ultimate dispatch flexibility. Financial Benefits: EaaS approach eliminates upfront cost to the County for the project including all microgrid and charging infrastructure, and provides long-term cost predictability for energy supply. Economic Development: Created more than 50 construction jobs. A ribbon cutting ceremony to mark completion of the project was held on October 31, 2022 at the Silver Spring bus depot.
