1. What is the Self-Generation Incentive Program?

The Self-Generation Incentive Program (SGIP) supports the installation of new qualifying technologies that are installed to meet all, or a portion of, the electric energy needs of a facility. Intelligent energy storage systems like EIBS contribute to achieving SGIP goals of reducing Greenhouse Gas (GHG) emissions, lowering demand and consumer purchases from the grid, and transforming the market to be more favorable to distributed energy resource (DER) technologies.

2. Who administers the SGIP incentive?

The SGIP was approved by the California Public Utilities Commission (CPUC) and is run by designated Program Administrators (PAs). Pacific Gas and Electric (PG&E), Southern California Edison (SCE), the Southern California Gas Company (SoCal Gas), and the Center for Sustainable Energy® (CSE) are the PAs as designated by the CPUC. Authorized incentive allocation through 2019 for each PA is as follows:

  • Pacific Gas and Electric Company (PG&E): $217,620,000
  • Southern California Edison Company (SCE): $169,260,000
  • Center for Sustainable Energy (CSE): $66,495,000
  • Southern California Gas Company (SoCal): $48,360,000

3. How are SGIP incentives allocated and how is it tracked?

SGIP incentives will be allocated in five steps throughout 2019. The progression of each step is controlled individually by each PA until the allocated funds for each step are exhausted. Please check this link for tracking the steps of each PA.

4. What portion of the SGIP incentives are allocated specifically for energy storage systems?

Specifically, this program allocates 80% of the funds ($501,735,000 through the end of 2019) for energy storage technologies, with 13% of the energy storage category carved out for small residential projects less than or equal to 10 kW. The portion of funds set allocated for small residential storage is set per step by each PA and is allocated independent of the total allocation established by the CPUC.

5. What is the incentive allocation for the Energy Storage Equity Budget?

Starting from the step 3, 75% of energy storage funds will remain in the general budget and the remaining 25% will be directed to the Equity Budget to provide incentives for customer-sited energy storage in disadvantaged and low-income communities in California. Please check this link to see if your installation site is in a disadvantaged and low-income community.

6. How much of a financial incentive is EIBS eligible to receive?

The amount of SGIP incentive allocated is dependent upon when the application is submitted and at which step of the program. Incentives are reduced based on how quickly the funds from the previous step were exhausted. Currently, most PAs are accepting applications for Step 2.

The approximate incentive rate for an EIBS system with a single storage battery (considering 7.4 kWh and 2 kW discharge power) is provided below.

Step 1

Incentive: $2850.00

Step 2

Incentive: $2280.00 / PA: PG&E / Active Step: 2

Step 3

Incentive: $1995.00 / PA: SCE / Active Step: 2

Step 4

Incentive: $1710.00 / PA: SoCal / Active Step: 2

Step 5

Incentive: $1425.00 / PA: CSE / Active Step: 4

7. Can I claim the Investment Tax Credit (ITC) with SGIP?

The ITC can be claimed with SGIP for EIBS if the solar panels are installed at the same time. However, existing solar systems that previously received the ITC cannot receive the ITC again after installing the EIBS system. New customers that install a full PV system which includes the EIBS are eligible to receive the ITC + SGIP incentive, making for a faster rate ROI.

8. Who is eligible to receive the SGIP incentive?

EIBS must be located within the territory of utility providers in California and connected to grid to support the utility network (the system cannot be used solely as a home backup system). EIBS must cycle the battery to fulfill the electrical demands of the home by charging and discharging to be eligible for the SGIP incentive.

9. What is the application process to qualify for the SGIP incentive?

Home owners can apply individually or assign the developer/installer to file the application on behalf of the home owner. Application details can be found here. Tabuchi partners with SGIP incentive-approved developers/installers and will direct the customer to appropriate developers/installer based on their territory. The process to apply for the SGIP incentive can be summarized as below:

  • Step 1: Customer or Tabuchi-assigned developer/installer submit the SGIP paperwork.
  • Step 2: SGIP inspector reviews the submitted paperwork and system operation after installation.
  • Step 3: Customer receives the rebate from the corresponding utility company.

10. What are the post-installation SGIP reporting requirements?

Customers must follow the “Residential Energy Storage Eligibility Affidavit” for five years after installation. Based on the affidavit, customers are required to report performance data to SGIP upon request for a period of five (5) years and incorporate tools to control use of the storage system. Remote data monitoring and control is available through the Tabuchi Cloud. The Battery Management System (BMS) can be controlled and operated with the help of a remote controller that is installed in each house. Customers are also required to discharge a minimum of 52 full discharge cycles per year, which is 384.4 kWh with one battery and 769.6 kWh with two batteries for the EIBS. Tabuchi guarantees the minimum number of required SGIP discharge cycles through its intelligent operation.
