Energy-as-a-service project to support Montgomery County e-bus fleet

AlphaStruxure is implementing an energy and charging infrastructure that integrates solar canopies and microgrid controls to help Montgomery County progress its net zero goals.

Montgomery County has embarked on a project that will enable 44 buses in its transit fleet to transition from diesel to electric, reducing emissions in alignment with its carbon neutrality ambitions.


The Brookville Smart Energy Bus Depot is a first-of-its-kind integration of microgrid and EV charging infrastructure that aims to provide sustainability, reliability and resilience for the county’s public transportation system.

The agreement will see energy-as-a-service (EaaS) solutions provider AlphaStruxure design, build, finance, own and operate the project to support transit operator Ride On’s growing electric bus fleet.


The project is designed to deliver benefits and outcomes including:

  • Bus electrification: enabling the County’s transition from fossil fuel buses to electric buses with a customised energy and infrastructure solution
  • Environmental sustainability: 62 per cent carbon emissions reduction with electric buses powered by the microgrid and lifetime greenhouse gas benefit of 155,000 tons, helping to advance the county’s goal to reach net zero carbon emissions by 2035
  • 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: energy-as-a-service 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: creates more than 50 construction jobs.

The Brookville Smart Energy Bus Depot project will utilise Schneider Electric’s EcoStruxure platform, including its top-ranked microgrid controllers and electrical distribution equipment.

“I’m pleased that this project will also improve the county’s resilience, so we can continue providing transportation services even in the event of prolonged power outages”

Leveraging relationships with industry-leading partners, the project integrates: clean energy including solar photovoltaic canopies designed and built by SunPower; AB Energy USA onsite generation with a carbon neutral fuel transition strategy; Dynapower battery energy storage; charging and energy management software, ChargePilot from the Mobility House; and Heliox chargers.


Mortenson will provide construction services and Arup will serve as engineer of record. AlphaStruxure will operate the project via a cloud-connected network operations centre providing 24-7-365 operations, monitoring and optimisation of energy performance.


“This advanced infrastructure project drives forward several of our priorities – converting our fleets to electric, reducing harmful emissions, and ensuring safety and security – in alignment with our ambitious climate goals,” said Marc Elrich, executive, Montgomery County.


“I’m pleased that this project will also improve the county’s resilience, so we can continue providing transportation services even in the event of prolonged power outages.”


AlphaStruxure is a joint venture of Schneider Electric and the Carlyle Global Infrastructure Opportunity Fund.


Beyond microgrid fleet electrification projects, AlphaStruxure partners with energy-intensive and energy-sensitive clients spanning commercial, industrial, government, and critical infrastructure sectors to deliver custom EaaS solutions.
