How does this Program interact with other EV programs?

This Program is not related to other EV programs. Below is a table provided for guidance on some common EV programs in Massachusetts. While all due care has been taken to provide the information below, applicants should consult directly any documents related to any other programs or rebates they have participated in to ensure continued compliance.

Demand Response Programs

Program Name	Administered By	Description	Can this be used together with the MassCEC Program?
Connected Solutions Program	Eversource, National Grid, and Unitil	Customers can receive an incentive for dispatching their EV batteries during ISO NE peak demand events.  Commercial Customers can choose to dispatch on a targeted basis (up to 8 times per Summer season) or on a more regular basis (30 to 60 times per Summer season.) Residential customers would need to respond the 30-60 times per summer	Yes.
Connected Homes Program	Massachusetts Municipal Wholesale Electric Company	Expected in July/August 2025	Yes

ENE does not have a DR program at this time. There is potential for ENE to have one by the end of 2025, but there are no expected conflicts. Customers would likely be use the DR program with the MassCEC program.

Who owns the equipment once installed as part of this program?

You will own this equipment from the time of installation.

How long is the pilot program?

The pilot program will conclude on December 31, 2026.

Is there any general guidance on insurance requirements or documentation that homeowners should confirm before installation?

The Program is not able to provide guidance on insurance-related questions. We recommend you reach out to your insurance agent if you have questions.

How are the utilities engaged with this program?

This Program is run by MassCEC, who has been engaged with Massachusetts utilities for a long time. The Program continues to work closely with the utilities as part of preparing the installations, enrolling in different programs, and gathering lessons learned.

How will V2X scale?

This Program will provide data to MassCEC on how this can scale in the future. We'll make recommendations as a part of the Guidebook that will be published at the end of the Program.

What is the program doing to work with legislators and regulators about V2X?

Program learnings and challenges are documented and shared with legislators and regulators during EVICC meetings. The formal guidebook at the end of the program will also inform future policy efforts.

Will there be requirements to be plugged in at certain times?

You won't be required to be plugged in at certain times as part of the MassCEC Program. However, if you stay plugged in for longer it increases the likelihood that you can see benefits—including revenue—from V2G since there is more time your EV battery is available for charging/discharging. Please note that the MassCEC Program will collect learnings about customer behavior, including plug times.

What programs might we be enrolled in?

This will depend on your utility. Please see the V2X and Utility Programs section for more information.

How do we know what is happening with the battery when there is a Connected Solutions event to participate in?

You will be offered a chance to enroll in the ConnectedSolutions Program by either Sunrun (if you own a Ford) or The Mobility House (if you own a Kia or Nissan LEAF). Once enrolled, your participation in ConnectedSolutions events will always be optional. These events are typically 3 hours long and occur 30 to 60 times during the June 1 to September 30th season. During an event, you can earn compensation for discharging a home battery: in this case, your EV. When an event is scheduled, you will be notified up to 24 hours before the start of the event. Notifications will come by email or from your charger app, the type varies by charger provider.

More information about the ConnectedSolutions program, including how you can participate and how you will be compensated, will be provided during the ConnectedSolutions enrollment process.

What happens if your circumstances change during the pilot?

It is expected that applicants will reside at the installation site and remain in possession of the vehicle they applied with throughout the Program. If your circumstances change, please let the Program know as soon as possible so we can either reallocate the funding or, if the install is completed, work with you on the most logical next step.

Does the V2X system have any additional battery storage beyond the storage in the EV so that it would be able to dispatch when the car is not plugged in?

None of the V2X systems that are funded by the MassCEC Program will come with additional battery storage. If you're interested in installing additional battery storage, please make the Program aware as soon as possible so we can attempt to accommodate that as part of your system design.

Is the equipment to be installed the same as what is offered/recommended by the vehicle OEMs (Ford, Kia, Nissan)? Am I guaranteed compatibility with the vehicle and its warranty?

The chargers being funded by the MassCEC Program are the same models that are recommended by your EV OEM. The Program worked with each automaker and charger manufacturer to guarantee compatibility between your EV and the preferred charger. We are continuing to work directly with the OEMs to employ their approved installers.

Do you have to be part of Connected Solutions to be part of the V2X Program?

No, you do not. If it is available through your utility you are encouraged to enroll, but it is not a Program requirement. For those who cannot participate or choose not to enroll, the Program will plan to issue discharge events at the same time as the Connected Solutions events because those are times when the electrical grid as a whole is strained. You will have the option to opt-out of these discharge events by responding to a notification on your charger app or email. For Kia and Nissan LEAF owners, The Mobility House will provide more information about how we'll interact with your device, how you can opt out, and how you'll be notified once your charger is installed. For Sunrun customers, please visit their website or helpline evtrainers@sunrun.com.

Bidirectional EVSE Technology

What other vehicles can these bidirectional chargers be used with?

All three chargers that are part of the program can be used to charge other vehicles, as long as they have the same type of charging port. For questions about using adaptors to charge, please reach out to your vehicle manufacturer to confirm.

For discharging, as of November 2025:

• The Ford Charger/SunRun Home Integration System can discharge the Ford F-150 Lightning.
• The Wallbox Quasar 2 can discharge the Kia EV9.
• The Dcbel Ara can discharge certain models of the Nissan LEAF, the Polestar 3 and the Volvo EX90.

The list of vehicles able to discharge is likely to change as new vehicles are released and new partnerships established. Discharge capability requires compatibility between the vehicle and the charger, which depends on the vehicle make, model year, software package and charger model.

The MassCEC Program team worked to verify that your EV would be compatible with the funded charger during the selection process and will continue to verify that with the charger manufacturers before installation. While waiting for your system, please confirm the following: (1) installed software in your vehicle allows for grid-parallel bidirectional discharge (some EV models require a software upgrade) and (2) your VIN does not have any relevant recalls. This will help ensure a smooth installation. If you have any concerns or recalls, please alert the Program team using the Program email: masscecv2x@resource-innovations.com.

Is it possible to have a bidirectional system installed if you also have batteries installed?

This will depend on the bidirectional EVSE you are planning to have installed, the circumstances of your individual set up, and whether or not the different devices are designed to work together. As a general rule, it is not currently possible to install the SunRun Home Integration system with existing batteries on site, but it may be possible to install the Wallbox Quasar 2 and the Dcbel Ara with existing batteries. As part of the MassCEC Program, B2Q will create an electrical design for the charger at your home, which will confirm what is possible for your set up.

Will the program pay for the installation of a second meter to allow me to be part of the V2X pilot program and keep net metering?

Will the program pay for the installation of a second meter to allow me to be part of the V2X pilot program even though I have other systems that are not compatible with the V2X system I'm eligible for?

My installation is not possible due to previously installed solar and/or storage. Will the program allow me to be part of the pilot program should I install a second meter myself so that the installation of the V2X is technically possible and/or does not interfere with net metering?

The program will not be paying for second meters or completing installations for grantees who independently install a second meter designated for V2X. This program seeks to prove out a variety of different V2X use cases, but is focused on those which we believe are scalable, or at least provide information not otherwise available. Installing a second meter is not a scalable solution due to the additional cost. The team has collected information related to V2X installations with solar and batteries and will provide information in the Guidebook to help guide situations like this in the future.

Bidirectional EVSE Installation

How can I find an installer for my EVSE outside of this Program?

This will partly depend on which type of V2X system you want to install.

• Most bidirectional charger manufacturers partner with installation services. Check the site of the EVSE vendor your EV is compatible with to find information on their preferred installation vendors.
• You can also look at the list of utility-approved vendors for your territory. Utilities have provided lists of these vendors before for unidirectional charger installations.

What does a typical residential bidirectional EVSE set up look like?

Bidirectional EVSE installations each have their own design based on the situation at the residence, the EVSE being installed, and the utility requirements. For images, please check out the website of the charger manufacturer.

Bidirectional EVSE Systems and Solar

I have solar installed at my house. How would having a bidirectional system impact my net metering?

This will depend on your territory and utility. In Massachusetts Investor Owned Utility territories, as of January 2026, it is not possible to receive compensation from the Massachusetts net metering program if you have a grid-parallel bidirectional charger installed at your home. However, it may be possible if you are in a Municipal Light Plant territory. You should confirm with your utility prior to moving forward with installation.

Can I be compensated for my solar output to the grid without net metering?

While there are other programs available that can compensate for solar, at this point it is not possible to compensate Massachusetts residents in Investor Owned Utilities like Eversource, National Grid and Unitil for excess energy from their installed solar if they also have a V2X system. This is because it is not possible to differentiate between solar energy being fed back to the grid and vehicle discharge back to the grid. Residents who chose to install a V2X system would be able to offset their home coincident energy use with solar, but would not be able to receive compensation for any solar fed back to the grid. In other words, any electricity your household loads used at the same time as your solar system producing electricity would be offset. Any household electricity use where the solar is not producing (for example, at night) would not be offset and would be charged using your residential tariff.

Will it be possible for me to earn net metering compensation while having a V2X system installed in the future in Massachusetts?

Current net metering rules in Massachusetts Investor Owned Utility Territories as of November 2025 do not allow participants to receive net metering compensation if there is a V2X system installed at the home. We do not know how this might change in the future or whether it would be possible to rejoin the net metering program after a V2X charger is installed.

Is it still possible for residential solar customers to take part in V2H in Massachusetts and have net metering?

Solar customers can install a V2X system that allows for grid-isolated V2H (that is, a V2H system installed only to provide backup power when the grid is not providing power to the home) and continue to be compensated for net metering. However, solar owners cannot install a grid-parallel V2X system without their net metering eligibility being affected. Because the MassCEC Program is focused on the grid-parallel aspects of the V2X technology, we'll be installing grid-parallel V2X systems.

V2X and Utility Programs

ConnectedSolutions

Program Overview

Goal: incentivize clean energy technology that supplies electricity or reduces demand during DOER-established peak demand periods.

Compensation and Program Design

• Season: from June 1 – September 30. 30-60 events per season, typically 45.
• Events: Between 3pm - 8pm, <3 hours per event.
• Compensation: $200/kW for participating commercial entities; $275/kW for participating residents

How can I calculate the revenue that I could earn from the ConnectedSolutions Program?

You can calculate your expected ConnectedSolutions revenue using the information provided by MassSave on page 6 here. We've provided a few example calculations below. For both scenarios, we assume the driver's utility rate charges $0.35/kWh (including supply and distribution costs) and that there are 45 demand response Events called during that ConnectedSolutions season.

Perfect Behavior

• EV charger discharge rate during Events: 10kW
• Hours the EV is discharging during the Event: 3 hours
• Portion of Hours the EV is discharging during 3-hour Events: 100%
• Portion of Events the EV participates in throughout ConnectedSolutions season: 100%
• Cost to charge during the season: [$0.35/kWh] * [10kW] * [3 hours/Event] * [45 Events/season] * [100% Event participation] = $157.50.
• ConnectedSolutions revenue: [$275/Average kW discharged during an Event] * [10kW] * [100% Hourly participation] * [100% Event participation] = $2,750.00

This example assumes this vehicle is discharged at the charger's rated power for the full duration for every event of the season. Actual discharge rate may vary. Your participation is dependent on your mobility needs, vehicle state of charge when plugged in, plug-in behavior, and whether you opt-out of any events. See below for an example that attempts to reflect more realistic participant behavior, where the EV is plugged in and able to participate in only 30% of the events.

Realistic Behavior

• EV charger discharge rate during Events: 3kW
• Hours the EV is discharging during the Event: 3 hours
• Portion of Hours the EV is discharging during 3-hour Events: 100%
• Portion of Events the EV participates in throughout ConnectedSolutions season: 30%
• Cost to charge during the season: [$0.35/kWh] * [3kW] * [3 hours/Event] * [45 Events/season] * [30% Event participation] = $14.18.
• ConnectedSolutions revenue: [$275/Average kW discharged during an Event] * [3kW] * [100% Hourly participation] * [30% Event participation] = $247.50

Please note the service contract terms of the provider that has enrolled you in ConnectedSolutions will vary and may impact your compensation. More details will be shared during the ConnectedSolutions enrollment process after the installation of your V2X system.

Both of these examples do not account for the money saved on electric bills by using the V2X system to offset home loads.

Can you help me understand what would happen to the ConnectedSolutions payment if the vehicle does not discharge, or only partially discharges, during an event? What about data share?

Zero Discharge During an Event

If the battery (or vehicle) does not discharge at all during a demand response event, the performance for that event is recorded as 0 kW. This directly impacts the average seasonal performance and, consequently, the incentive payment.

Partial Participation During an Event

If the battery begins discharging partway through the event (e.g., plugged in after the event starts), the performance is still calculated over the entire duration of the event. For example, in a 4-hour event where the battery discharges 8 kW for the last 3 hours but not the first, the average performance would be: 0+8+8+8/4=6 kW.

Variable Discharge Rates

Similarly, if the discharge rate varies throughout the event, the performance is calculated as the average kW discharged over the full event period. That is then averaged over the full ConnectedSolutions program season. This ensures consistency and fairness in performance measurement across all participants.

Data Requirements

Approved inverter manufacturers are required to provide 15-minute interval data (or more granular) for the entire season. Collected data includes the amount of power (in kW) and energy (in kWh) that you use to charge or discharge across your charger's inverter. This data is used to calculate event-level and seasonal average performance, which directly determines the incentive amount. For devices funded by the MassCEC Program, The Mobility House will be collecting this data for enrolled dcbel Ara and Wallbox Quasar 2 devices; Sunrun will be collecting this data for enrolled Sunrun Home Integration Systems.

At what rate will my EVSE discharge during a peak event?

The rate of discharge will depend on your current battery state of charge (SOC), your minimum state of charge (for example, if you'd like to always leave 20% battery capacity by the end of an event) and the duration of the event.

I own battery storage that is already enrolled in the ConnectedSolutions Program. Can I have both my battery storage and my V2X System enrolled in the Program?

If you have a home battery you will be able to participate in the ConnectedSolutions Program alongside your V2X system. Your home battery will stay enrolled in the program through your battery provider; The Mobility House (or Sunrun, if you have a Sunrun Home Integration System) will enroll your EV in the ConnectedSolutions Program. At the end of the Program, you will be compensated separately for the power that is discharged from each system.

Does Connected Solutions apply residents in MLPs?

No. Only Investor Owned Utilities (in MA, National Grid, Eversource, and Unitil) are able to participate in Connected Solutions

Should I assume I will get the maximum amount of the Connected Solutions payment under the V2X program?

Because the primary use of your vehicle is transportation and not storage, it is hard to know how individuals will participate in 'real life': that is one of the things this program is looking to understand. Factors that will impact your participation (and compensation) include, but are not limited to, when you plug in your car, the state-of-charge of your vehicle battery at the time of an event, your mobility preferences, and how your V2X system is managed by The Mobility House or Sunrun. Your summer participation could be impacted by vacations or if you're enjoying events outside the home. There is also the chance that you plug in your EV with a reduced charge that prevent you from fully participating in every single event.

Clean Peak Standards

Program Overview

Goal: to curtail customers' electric energy when the ISO New England ("ISO-NE") system is forecasted to be at peak.

Compensation and Program Design

• Participants are compensated with Clean Peak Energy Certificates (CPECs) for reducing load compared to a baseline during Seasonal Clean Peak Windows.
• Seasonal Clean Peak Windows:
  • Spring (Mar 1 – May 14): 5pm to 9pm
  • Summer (May 15 – Sep 14): 4pm to 8pm
  • Fall (Sep 15 – Nov 30): 4pm to 8pm
  • Winter (Dec 1 – Feb 28): 4pm to 8pm
• CPECs in 2026 are valued at ~$65 per MWh.

How can I calculate the revenue that I could earn from the Clean Peak Standards Program?

Calculating the revenue earned per asset as part of the Clean Peak Standards Program is complicated because it depends on the value of the sold CPEC, the time at which you charge and discharge, and the amount of energy used to charge and discharge. Full details are described here: https://www.mass.gov/doc/225-cmr-21-clean-peak-energy-portfolio-standard-cps/download. In general, the Program rewards the following behaviors:

• Charging during off-peak hours outside the Seasonal Clean Peak Windows
• Reducing load during Seasonal Clean Peak Windows by pausing charge or discharging energy

There are multipliers that help you earn even more compensation described here: https://www.mass.gov/doc/cps-cpec-generation-formula-visualization/download. You can earn more CPECs if you own solar, participate in the Summer and Winter seasons, or if you happen to participate during a Window that coincides with the electric grid's monthly system peak demand.

If you were to avoid charging during the Seasonal Clean Peak Windows every day, you could probably expect to earn between $15 and $100 for the year depending on the amount of energy you need to charge your EV (more CPECs earned for more energy consumed off-peak). If you were to discharge during some of the Seasonal Clean Peak Windows, you could expect to earn >$100 for the year depending on your rate of discharge and the amount of energy you need to charge your EV. Please note that these examples are high-level estimates and don't account for the cost to charge your EV.

Time of Use Rates

Will residents on TOU rates be able to stay on those rates or is that not compatible with the V2X set up?

Yes, customers who are already on TOU rates will be able to stay on those rates. Those rates are typically not impacted by the type of equipment installed. In fact, you are encouraged to stay on your TOU rate so that we can manage your EVSE to save you money on your electric bill.

What Time of Use Rates are available for residents in Massachusetts?

Neither Eversource nor National Grid have TOU rates for residents currently. The only mandatory TOU rate in any MA town is in Groton, MA. There are voluntary TOU rates in place in the following MLPs: Reading MLP, Sterling MLD, and Wakefield Municipal Gas and Light Department.
