Benefits of battery storage
The many benefits of battery storage systems include:
- Providing backup power during outages
- Reducing your electric bill by using excess energy during peak hours when electricity is most expensive
- Helping the environment by shifting your excess solar generation to peak periods, reducing your carbon emissions

My Energy Optimizer Partner+ incentive
Take advantage of our battery storage incentive available for residential customers.
How it works
By joining our battery storage incentive program, My Energy Optimizer Partner+, you can earn financial incentives for making your battery storage unit an even smarter device.
When you partner with us, your battery will reduce energy usage during the hours when demand is highest and clean energy resources are scarce. This could include shifting the time when your battery is used to power your home. The interactions would be seamless to you and no extra effort is needed on your part.
Program participants will have full access to the amount of power available in their battery storage system during a power outage. SMUD will always leave customers with a 20% reserve at the end of an event in case of an outage overnight.
The following battery systems are eligible for incentives:
See the My Energy Optimizer Partner+ Terms and Conditions for more program details.

Enrollment incentive
My Energy Optimizer Partner+ includes a one-time enrollment incentive of up to $10,000 per household if the project is submitted for interconnection by Sept. 22 and enrolled in the program by Dec. 31, 2026. Interconnection applications received on or after Sept. 23, are eligible for the new (lower) incentive up to $6,000. The enrollment incentive is available to new battery energy storage system (BESS) customers that enroll within 90 days after receiving permission to operate (PTO) from SMUD. The requirement to enroll in the program within 90 days of receiving PTO applies to both the current and new (lower) incentive level. Income-qualified customers whose battery system, solar system or equipment costs are fully covered by SMUD, are eligible to participate in the program, but are not eligible for the one-time enrollment incentive.
Quarterly incentives
Currently, ongoing quarterly incentives are only available for Tesla batteries, which are optimized year-round and will continue to be available for customer use, such as backup power needs in the event of an outage. Other qualified battery manufactures may participate in the incentive program but are only eligible to receive the enrollment incentive at this time.
Eligibility requirements and information
- To be eligible for this program, you must have a battery storage unit installed at your home and participate in SMUD’s Solar and Storage Rate (SSR).
- Individual rental units are ineligible at this time until SMUD determines a way for owners and their tenants to mutually benefit from the program. Multifamily homes (including apartments, condos and duplexes) are eligible as well but same tenant restrictions apply.
- MED Rate customers are not eligible for the My Energy Optimizer Partner+ program.
If you’re adding a new solar system with battery storage or a battery storage system only, there's a one-time interconnection fee to connect to SMUD’s grid to recover the cost of providing interconnection service. Your solar installer should already be aware of this fee. If you're adding battery storage to an existing solar system, an interconnection fee does not apply.
Incentive amounts
Effective Sept. 23, the upfront enrollment incentive will reduce from $500 per kWh (up to $10,000 per household) to $300 per kWh (up to $6,000 per household). Projects must be both submitted for interconnection by Sept. 22 and enrolled in the program by Dec. 31, 2026, to be eligible for the current (higher) incentive. All customers are still required to enroll in the program within 90 days of receiving PTO. Incentive amounts below reflect a 20% reserve.
Note: Quarterly incentives currently only available for Tesla (1 battery: $110, 2 batteries: $220, 3+ batteries: $330)
