Home Battery Storage Incentives

Helping homes install battery storage

The California Public Utilities Commission (CPUC) offers financial incentives for battery storage systems. The Self-Generation Incentive Program (also called SGIP) is available to customers throughout California.

Simplifying the process

Installing a battery system provides energy resiliency along with other benefits. Yet the upfront cost to install a battery can be high. SCP delivers customers the financial incentive at the beginning of your project. We also help with applying for the Self-Generation Incentive Program.

Financial Incentives

All residential customers can apply to the Self-Generation Incentive Program. Funding is available on a first-come, first-served basis. Over time, the incentive amount gets smaller. There are several different levels of rebates depending on your battery size and capacity.

General Rebate – Small Residential Storage

For projects 10 kilowatts and below.

Incentive: $150/kilowatt-hour.

Eligibility: Currently only applications for resiliency customers are being accepted. Resiliency customers live in High Fire Threat Districts (Tier 2 or Tier 3) or have experienced 2+ Public Safety Power Shutoffs (PSPS).

General Rebate – Large-Scale Storage

For projects 10.1 kilowatts and above.

Incentive: $300/kilowatt-hour or $220/kilowatt-hour if you also apply for the Investment Tax Credit.

Equity Resiliency

Equity Resiliency is the highest incentive available at $1,000/kilowatt-hour.

To receive this financial level, customers must meet several requirements listed below.

Step 1: Meet one main requirement

• You live in a Tier 2 or Tier 3 High Fire Threat District (view map)

OR

• You have experienced 2+ Public Safety Power Shutoff events

Step 2: Meet one more requirement

• You are eligible or enrolled in Medical Baseline (more information available here)
• You have notified PG&E of a life-threatening illness/condition if the power shuts off
• You rely on electric-pump wells for water supply*
• You live in a disadvantaged community
• You are a low-income renter or homeowner
• You are participating in an affordable home solar program (more information available here)

*Customers who select this item must meet additional requirements including income limits.

Eligibility

Any residential SCP customer can take part of this program. Customers must sign a customer agreement which says:

• I am an active SCP customer
• I will assign the SGIP payment to SCP in exchange for up-front payments
• To share battery data with SCP
• I will pre-enroll in a future GridSavvy Rewards program offered by SCP. Customers may always opt out of participating.

Questions?

How can I become a participating installer?

Please email programs@sonomacleanpower.org for more information on participating in the program.

May I use this program to install a battery used only for emergency back up?

No. The Self-Generation Incentive Program requires that battery systems charge and discharge. This will help meet your onsite electrical needs. It will also help the electric grid. But don't worry, it can keep some energy stored in case of emergencies. If PG&E announces a planned power outage, like a Public Safety Power Shutoff, you can keep it charged up. As long as it reaches the equal of 100% discharge once a week, it qualifies.

Do I need solar?

No, you do not need solar to add a battery. But without solar, you will not be able to recharge the battery during a power outage.

Solar plus battery storage provides other benefits. You can save money, reduce your carbon footprint and help the grid. You can charge the battery during the day with clean solar power. Then in the evening when the grid power is less clean and more expensive, your home can draw power from the battery.

Who does the incentive go to?

SCP can send the incentive to either the customer or the installer. Let us know when you apply.
