All enrollees in Flex Batteries will receive

• A one-time enrollment incentive of $1,000 (per battery) by check
• An annual participation incentive of $500 in a form of an e-gift card with options to a wide variety of major retailers. Participants can track progress toward meeting performance requirements for the annual incentive in their FlexSaver account.

You will receive your enrollment reward in the form of a check within 4-6 weeks after enrollment and receiving a completed W9. Then, at the end of the summer season, you will also receive payment in the form of an e-gift card for participating in Flex events.

Participants who enroll are automatically entered to win one of two $250 gift cards. Giveaways will be drawn each month during the summer season (May 1 through September 30) and winter season (November 1 through March 31).

Flex Batteries is administered on behalf of PSE by AutoGrid, overseeing program implementation, payment processing, and customer support. Enrolled customers can manage their accounts through the FlexSaver portal provided by AutoGrid. For the fastest assistance, you can contact AutoGrid's customer support directly at flex@517b2b.com or by calling 1-888-292-0502.

Enrolling your battery requires that your home be equipped with AMI (Advanced Metering Infrastructure), the current standard for metering technology that facilitates two-way communication between meters and PSE. As part of PSE’s Meter Upgrade Project, nearly 2 million meters in our service area were upgraded to AMI between 2018 and 2023. For more information, please visit the Meter Upgrade Project.

Yes. For information and resources to learn more about installing solar at your home, please visit Customer Connected Solar.

Yes. You can enroll other qualified smart devices in PSE Flex Smart and Flex EV.

However, if you are signed up for Flex Rewards already, you will need to unenroll to participate in Flex Batteries.

If you would like to remove your battery from Flex Batteries and no longer participate in events, please contact flex@517b2b.com.

Our experts can predict periods with heightened demand for electricity based on a range of different criteria, which we call “Flex events.” For example, a Flex event might occur on a day with weather hotter or colder than normal, when we tend to use more energy to heat and cool our homes and businesses.

With collective action from the community, we can prevent spikes in energy usage that strain the grid and ensure there is enough energy to go around.

When PSE schedules an event, your device might receive an automatic command to charge up from your solar or from the grid ahead of the event. When the Flex event starts, your battery system will automatically start to discharge over the duration of the event. You do not need to do or change anything to participate in the event.

If your home or neighborhood is currently experiencing an outage such that your battery is already discharging to back up your home, your battery will automatically be excluded from the scheduled Flex event

Through AutoGrid’s integrations with the participating manufacturers, PSE can schedule events that send automatic commands to the participating devices. These commands take into account the current status of the device, including state of charge. Devices will never be discharged less than 20% of the battery’s capacity.

Flex events will only occur during the hours of 6 a.m. to 10 p.m. and will never take place on holidays (see list below).

• Winter events can occur from November 1 to March 31
• Summer events can occur from May 1 to September 30.
• PSE may call upon your battery up to 30 times per season.

Holidays:

• New Years
• Memorial Day
• Independence Day
• Labor Day
• Thanksgiving
• Christmas

No, events are structured such that the battery response is automatic and you do not need to do anything.

By default, you will not receive a notification of your battery’s participation during a Flex event from AutoGrid or PSE. However, you may receive a notification from your battery manufacturer, depending on your battery setting.

If you would like to receive a notification from PSE, please contact AutoGrid’s customer support directly at Flex@517b2b.com or by calling 1-888-292-0502.

By default, you will not have the option to opt out of a Flex event. However, you may opt out of events as supported by the device manufacturer.

If you have solar panels and a qualifying battery, you can participate in both Flex Batteries and PSE Net Metering. The combination solar and battery system will need to be approved through our interconnection process. Then, through net metering, you can use or store the solar power you generate. At times when your solar panels generate more power than you can use or store, the excess energy will be sent to PSE's grid and you'll receive net metering credit. Learn more.

Yes, you can still participate in Flex Batteries with a storage-only system as long as it is an eligible system and is interconnected to PSE’s grid. When your battery sends energy back to the grid during events, your meter tracks this contribution, and PSE credits it back to your monthly bill. This ensures that you are not billed twice for the same energy—once for using it and again for sending it back during events.

If you're installing a storage-only system and want to participate in the Flex Batteries program, the installation process is similar to Net Metering, and you'll still need to work with an installer and apply for interconnection. Visit PSE’s Distributed Renewables page to get started.

If you’re installing a storage-only system for back-up power only and not interconnected to PSE’s grid, PSE offers installation guidelines.

If you’re installing a battery that is not interconnected to PSE grid, we strongly encourage installers and our customers to report their standalone battery installations throughout our service area by filling out and submitting this online notification form.

By sharing your information, you’ll help PSE properly manage the services that we provide to all customers on our grid. You will also help us evaluate further opportunities to support customers’ battery storage installations.

If you are planning to operate your storage-only system in parallel with PSE's grid (e.g., if your battery can provide energy to your load at the same time as the grid), then PSE requires that you have an interconnection agreement. Learn more about interconnecting at a storage-only system on PSE’s Distributed Renewables page.

Yes, the Federal Investment Tax Credit may apply to your installation. The Inflation Reduction Act of 2022 includes a 30 percent Investment Tax Credits for both standalone battery storage systems and solar plus battery systems. This includes systems installed in 2022 and will be available through the end of 2032. We encourage you to consult with a tax professional to fully understand the tax credit eligibility requirements. Learn more.

Many solar installers can help you access financing through a local credit union or other financial institution and explain how that impacts the cost, benefits and estimated return on investment from your installation.

Incentives for enrolling and participating in the programs are considered taxable income. As such, AutoGrid will collect W-9s from all participants before processing incentives so that AutoGrid has the necessary information to issue 1099 forms in January. The tax implications for each participant will depend on individual circumstances and we recommend you discuss with your tax professional.

W-9 forms will be stored securely with restricted access and used only for the purpose of issuing the 1099 forms.
