2027 Event Agenda

This session presents findings from the MassCEC V2X Program that funded approximately 1MW of bidirectional charging stations. The Mobility House (TMH) is the technology partner and optimizing both residential bidirectional charging (using Wallbox and Dcbel chargers) and commercial school bus fleet charging across National Grid and Eversource service territories. Most of these chargers are enrolled in the ConnectedSolutions Program, which will call 30–60 multi-hour demand response events per summer season. We'll share what we expected at the start of the season and what the data actually showed: load curves, demand response (DR) event outcomes, opt-out rates, V2G discharge performance, and plug-in availability during events.

We’ll also review the technology stacks that powers the optimization for the two customer segments. For residential customers, TMH built a full end-to-end product on The Mobility House Cascade Aggregation platform: this includes charger integrations with residential bidirectional charging station providers Wallbox and Dcbel, a customer-facing dashboard, and a VGI optimization engine that ingests tariff data, DR events, TOU windows, and mobility needs to produce a dispatch plan. For commercial fleet operators, the optimization layer is the same with the TMH Cascade platform receiving grid signals and optimizing for economics, but dispatch plans and site data flows through The Mobility House ChargePilot dashboard to bidirectional charging stations at the fleet sites.

Finally, we’ll discuss the complexity associated with three commercial sites: Boston Public Schools, Acton-Boxborough Regional School District, and Concord Public Schools. We'll explain why some schools were disqualified from the Program and we’ll walk through the scoping decisions made at each site and what they meant in practice.

This session is designed for utility DER program managers, VGI technology developers, and anyone interested in how these end-to-end systems work. The goal is to facilitate a data-driven session useful for utilities and technology partners who are designing or expanding their own VGI programs. Attendees will leave with:

• Real DR season data — opt-out rates, discharge performance, plug-in availability, and load curves across residential and fleet segments
• A utility-side perspective from Eversource on what program design choices made enrollment and operations easier or harder
• Understanding of user experience and behavior in this type of program with new technology
