About the California Hub for Energy Efficiency Financing (the Hub)

CAEATFA administers the Hub pilot programs as part of a public-private partnership among state agencies and investor-owned utilities (IOUs) to help California meet its energy savings goals by increasing private investment in energy efficiency retrofits. By the authority of the California Public Utilities Commission (CPUC), IOU ratepayer funds support administration of the Hub programs as well as a credit enhancement for participating finance companies. Access to the credit enhancement, which takes the form of a loss reserve fund that functions like insurance in the event of default, allows finance companies to offer more attractive financing to a broader base of customers. In turn, more Californians are able to undertake energy efficiency improvements for their homes and businesses. This mechanism for leveraging private capital is at the heart of the Hub programs.

The pilots seek to determine whether financing can yield the same type of energy savings as traditional utility rebates and incentives. Additionally, the pilots will test how on-bill repayment (OBR), through which customers can repay loans via their monthly utility bills, may encourage program uptake as well as improve loan performance. OBR functionality for the small business and affordable multifamily programs is scheduled to launch in late 2020.

The residential program completed its two-year pilot phase in 2018 and was approved by the CPUC to transition to a full program in April 2020. The small business pilot program was launched in 2019 and will be evaluated at the end of its two-year pilot phase. The affordable multifamily program opened for business in 2019 and will enter the pilot phase upon its first project enrollment.
