Dive into the latest updates, initial learnings, and what’s next for this ambitious initiative, unlocking the potential of EVs to support the grid.

MassCEC V2G Charger

The Massachusetts Vehicle-to-Everything (V2X) Demonstration Program is a groundbreaking initiative led by the Massachusetts Clean Energy Center (MassCEC), in collaboration with The Mobility House and Resource Innovations, to deploy bidirectional electric vehicle chargers across the state and demonstrate their capability to provide flexibility benefits to the electrical grid, all within a two-year program cycle (2025-2026). As of August 2025, the program has completed the technology qualification phase and is finalizing its selection of participants. This update will provide a brief summary of the program scope and objectives, developments to date, work still to come, and initial learnings.

Program Overview

This program is unique in its statewide scope, in the comprehensive funding model that makes it free to all participants, and in how it standardizes technology and implementation across multiple vehicle and charger types. 

In 2024, the Electric Vehicle Infrastructure Coordinating Council awarded MassCEC $38M to increase access to charging infrastructure for various sectors. Of that, $6.3M was dedicated to the MassCEC V2X Demonstration Program. As the program grantees, The Mobility House and Resource Innovations will use this funding to deploy up to 100 bidirectional charging systems across residential, commercial, and school district sectors. 

The program, which represents one of the largest state-led V2X initiatives in the U.S., will activate participants’ electric vehicles (EVs) as mobile energy storage assets, collectively totaling a targeted 1.5 MW of new energy storage capacity across Massachusetts. V2X is shorthand for “Vehicle to Everything,” an umbrella term that encompasses a variety of bidirectional charging use cases, including “Vehicle to Grid,” (V2G) in which power is discharged from the vehicle to the electrical grid for some form of compensation, and “Vehicle to Home,” (V2H), in which the vehicle battery acts as a source of backup power for a building. 

Here’s the program timeline: 

  • Technology qualification: Jan – April 2025 
  • Application period: April – July 2025 
  • Participant selection: June – Sept 2025  
  • Charger installation: Aug 2025 – June 2026 
  • Charger operation and data collection: Jan - Dec 2026  
  • Publication of a public-facing V2X Guidebook: Dec 2026 

The program is completely free of charge to participants. Benefits for selected participants include: 

  • Bidirectional charger with warranty 
  • Design & engineering work  
  • Installation of charger 
  • Interconnection fees  
  • (For fleets) Charging management software from The Mobility House, including subscription & service for 5 years  

Eligible Vehicles and Hardware

One of the milestones in the first phase of work for this program is to qualify the charging technology to be included in the program. To be eligible, the equipment needed to meet the following criteria: UL1741-SB certification (achieved or on track to achieve before charger operation), ability to discharge from an EV while grid-parallel, commercial availability, and compatibility with commercially available EV(s). The program team incorporated these requirements as a part of signed memoranda of understanding with the bidirectional charger manufacturers to confirm their eligibility and participation in the program. As one of the first state-wide V2X program in the US to operate across multiple utility jurisdictions with multiple hardware providers, this step was key in securing our interoperability goals. As a part of the agreement, Electric Vehicle Supply Equipment (EVSE) partners also agreed to share data from charge and discharge sessions. These eligible models of bidirectional chargers include: 

Residential chargers (split phase): 

  • dcbel Ara Home Energy Station  
  • Wallbox Quasar 2 with Power Recovery Unit 
  • Sunrun Home Integration System with the Ford Charge Station Pro

August 2025 Program Status and What’s Ahead

As of July 31, 2025, the program application period has closed and the team is finalizing participant selection for the program. Project partners B2Q and Voltrek have begun site evaluations, designs and installation pre-work for each selected participant. 

One key goal of the program is to identify V2G value streams available to residential, fleet and school district customers in the state of Massachusetts. These potential value streams vary across customer classes and utility service territories. The program will enroll participants in demand response programs, such as Connected Solutions, or other opportunities for grid services for the duration of the program.  

Once enrolled, participants will have the opportunity to participate in V2G events, typically called during summer months to support the grid when demand is high. Vehicle owners will receive a notification before the start of an event and will have the option to participate or opt out. During an event, the vehicle will begin to discharge power if the following criteria are true: the vehicle is plugged in, the owner does not opt out, and the vehicle state of charge is above the owner-designated minimum required for participating in the event.  

The Mobility House commits to deliver commercial-grade support to both residential and commercial participants in this program to prioritize the core experience of reliable charging, ensuring mobility needs are continually met without compromise. Participation in V2G events will be compensated by the utility based on vehicle participation data tracked by The Mobility House. 

One of the primary goals of the MassCEC V2X Demonstration Program is to move fast and gather data and learnings to inform the larger utility industry. These insights will be compiled into a “V2X Guidebook” that will be made publicly available to inform future programs in Massachusetts and elsewhere. 

Initial Learnings: Customer Experience + Outreach

To successfully launch this project in North America, The Mobility House relied on experience from our pioneering efforts in France, where we launched the first active V2G program for personal vehicles offered by a major automaker with Renault. Even with that experience, we have already learned a lot while engaging with customers as a part of this program: 

Achieved full enrollment goals through a multi-channel marketing and outreach effort  

This indicates a high level of interest and demand amongst early adopters for V2G in the home. We also credit the 2-phase application that first included an “Interest Form” to capture early interest at the announcement of the program. Despite not having the comprehensive product details and eligibility criteria that was a part of the full application, the feedback was electrifying with several hundred responses. 

Concerns about V2G impact to vehicle warranty is a sticking point 

Customers had many questions about how bidirectional charging would impact their vehicle warranties, and every vehicle manufacturer had different terms and conditions. This created a communications challenge for The Mobility House as the program technology operator to ensure each vehicle owner understood long term impacts. 

Lack of technology interoperability is a challenge 

Customers want to know that the charger they are installing in their home would be compatible if they buy a new car or have a second car of a different model. Current bidirectional residential charging systems only operate with a single brand: this limited interoperability risks the quality of the customer experience and makes it difficult to justify the investment in the charger. 

Initial Learnings: Technology & Market

As the first implementation of a state-wide V2G program that operates across multiple utility service areas, and with multiple brands of vehicles and chargers, we have gained unprecedented insight into the state of vehicle-to-grid technology and the market. 

Growing V2X Options 

The options for bidirectional EVs and charging stations are growing. This program showcased what is currently commercially available with the required functionality for interconnection and grid-parallel V2G operation. The program installation deadlines created a cut-off for what can be included for the program, but we expect a growing number of EVs and EVSEs to enter the market during the program timeframe. 

Interoperable school bus charging ecosystem 

The electric school bus market has a relatively high level of interoperability with open communication protocols, in which most vehicle models are compatible with most of the available EVSEs. This creates an inclusive environment based on open standards, reducing the risk of stranded assets and allowing for more product choices for fleet operators. In contrast, many passenger vehicle manufacturers have created exclusive partnerships with EVSEs, creating proprietary ecosystems in which aggregators are either barred from integration or have to pay for a license.  

Limited availability of Bidirectional capable commercial vehicles and chargers 

It was challenging to find solutions for the commercial fleet segment. Very few commercial trucks, vans, pickups and other heavy/medium-duty EVs have V2G capability. There is also a gap in the bidirectional EVSE market: most EVSEs are either low power, suitable for residential applications (split phase), or high power to serve commercial buildings (3-phase), with no mid-range offering for light-duty fleets.  

Data sharing adds contracting complexities  

In order to create an inclusive, brand-agnostic program, and serving as the program’s software aggregator and one of the program administrators, The Mobility House had to play a critical intermediary role in securing agreements with vehicle and charger manufacturers. This included significant time and contracting to establish the details of how data would be standardized and shared. 

Initial Learnings: Installation and Interconnection

Preparing for the installation of these emerging bidirectional technologies has led to early learnings when it comes to integrating these assets into the electric grid. 

Engaging qualified stakeholders early has led to early wins  

Throughout the program implementation thus far, the distribution utilities have been highly collaborative. This is due, in part, to the statewide program structure, which has been valuable to quickly implement the latest developments in V2X technology, identify common challenges across utility territories, and incentivize utility partners to engage with lower risk. It has also been very helpful to have experienced installers on the project teams with existing relationships and familiarity with utility requirements and processes. And, as always, it has been a best practice to engage in early conversations with the utilities to streamline installation and interconnection. 

Ongoing conversations about Net-Energy Metering integrity 

Now that V2G is in implementation, the utilities are actively engaged in decision-making of how to treat electrons from batteries not charged with solar, with The Mobility House helping to facilitate discussions with regards to the Massachusetts V2X program, in addition to in other states. 

Integrating Multiple Distributed Energy Resources (DERs) 

Many customer applicants have existing EV, solar and battery systems that are enrolled in existing and overlapping programs for EV and DERs. As V2G leverages an EV to act as a stationary battery, it can be confusing to navigate where a V2G system fits into existing market program structures. Additionally, these additional existing systems can complicate installations and may increase installation cost. 

Higher capacity projects trigger delays that challenge timelines 

For certain service areas, projects exceeding 200 kW capacity are subject to additional study which often requires several months. This threatened the ability of some school and fleet customers to participate in the program, given the program timelines and budget. TMH worked with utilities and customers to design sites that would avoid this burdensome additional study by working collaboratively upfront.  

Conclusion

We are happy to provide these insights based on recent experience as transferable knowledge for utility providers and state program administrators to accelerate the realization of the promise of V2G. Next, we are excited to soon share photos and stories from some of the first installations for this program, as data becomes available.
