Participation

Once enrolled, your utility will call upon the VPP when the grid needs additional capacity and support. Events may be called as follows:

• Maximum of five events can be called per month
• Events can be called annually with a maximum of 170 hours per year
• Events will be no longer than 4 hours in duration
• Dispatch hours are between 4 – 8 PM
• Events can occur weekdays on non-federal holidays

What to Expect

• Before the Event: You may receive a notification from the Tesla app about scheduled events. Your Powerwall will prioritize charging and preparing for the event.
• During the Event: Your Powerwall will discharge to support the grid until the event ends, it reaches your VPP Event Backup Reserve level or you opt out.
• After the Event: Powerwall resumes normal operation.

Controlling Your Participation

Powerwall gives you three VPP participation options:

1. Set Your Backup Reserve: Adjust the VPP Event Backup Reserve setting to control your energy contribution during events. A lower reserve allows you to share more energy and earn more compensation.
2. Opt out of a Single Event: Use the Tesla app to opt out of any scheduled or active event.
3. Suspend Participation: Toggle off participation in the Tesla app VPP settings. This will stop Powerwall from reacting to future events until you resume participation.

Compensation

In your first full year, you could earn up to $360 for each Powerwall to participate in this program. Over the 10-year program, you could earn $3,600 in utility bill credits.

The program pays a $90 quarterly bill credit for each Powerwall enrolled in the program. The ongoing incentive per Powerwall is available for all municipal utilities. Concord Light customers are limited to receiving an incentive on one Powerwall system.

For those considering purchasing Powerwall, you could be eligible for a one-time, upfront incentive of $100 per kWh up to 20 kWh, as part of the program, depending on your municipal utility. A new Powerwall 3 system is eligible for an upfront incentive of $1,350. Participating utilities include:

• Chicopee Electric Light Battery Program  
• Marblehead Municipal Light Department Battery Program
• Shrewsbury Electric and Cable Operations Battery Program
• Sterling Municipal Light Department Battery Program   
• Templeton Municipal Light & Water Plant Battery Program
• Wakefield Municipal Gas and Light Department Battery Program
• West Boylston Municipal Light Plant Battery Program

Learn more about your utility’s eligibility.

Payment

Your program participation payment will be made quarterly in the form of a bill credit on your electric bill. The incentives earned are based on your Powerwall data as shared by Tesla.

Note: The program participation payments and NextZero upfront incentives are processed separately.

Your participation is subject to your agreement to be bound by these terms and conditions with Tesla (“Terms”). By clicking “Accept Enrollment” you (“You” or “Participant”) acknowledge that You have read these Terms and agree to be legally bound by them.

Tesla Arbitration Requirement

Agreement to Arbitrate

Read this part carefully because it means you are agreeing that any unresolved dispute between you and Tesla will not be decided by a judge or jury in a public courtroom, but instead by a single arbitrator in a private arbitration.

If you have a dispute arising out of or relating to any aspect of this Agreement and the relationship between you and Tesla, Inc. or its affiliates (which we call “Tesla”), send us an email to resolutions@tesla.com, describing your dispute and how you would like it resolved. If it is not resolved within 60 days from the date of your email, you agree that your dispute can only be resolved by a single arbitrator in an arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules. This includes claims arising before you ordered your System (such as claims related to statements Tesla made about our products). We will pay all AAA fees for any arbitration, which will be held in the city or county of your legal residence. To learn more about the Rules and how to begin an arbitration, you can call any AAA office or go to www.adr.org. The arbitrator can only resolve disputes between you and Tesla and cannot consolidate claims from others without consent from you, Tesla, and the others. You can only bring claims in arbitration against Tesla in your individual capacity and not as a plaintiff or class member in any class or representative action (and the same is true for Tesla). If a court or arbitrator decides that any part of this agreement to arbitrate cannot be enforced as to a specific claim for relief or remedy (such as what lawyers call “injunctive” or “declaratory” relief), then that claim or remedy (and only that claim or remedy) will be carved out of the arbitration and can be filed in court; all other claims must be arbitrated. If you prefer, you can take your individual dispute to a small claims court instead. If you don’t want to agree to arbitration, you can "opt out” of arbitration by sending us a letter within 30 days after placing your initial order for your System. Send the letter to Tesla, Inc.; P.O. Box 15430; Fremont, CA 94539-7970 and include your name, your order number, the name of the product you ordered and a statement explaining your desire to opt out of arbitration. If you do not opt out, your agreement to arbitrate overrides any different arbitration agreement between us, including any arbitration agreement in a lease or finance contract.
