On-bill financing, a tool that allows customers to pay for energy efficiency investments though their utility bills, is becoming more widely available across the country and extending opportunities to historically underserved markets, according to a new study.
The study, On-Bill Financing for Energy Efficiency Improvements: A Review of Current Program Challenges, Opportunities, and Best Practices, was released by the American Council for an Energy-Efficient Economy (ACEEE) and profiles 19 existing on-bill financing programs in 15 states. The study finds that these programs are poised to address financing gaps that have not been historically addressed by other energy efficiency financing mechanisms.
On-bill financing generally refers to a financial product that is serviced by, or in partnership with, a utility company for energy efficiency improvements, and repaid by customers on their monthly utility bills. In many cases, energy savings are sufficient to cover the monthly payments for the financing so that the total monthly charge on utility bills is less than or equal to the pre-investment amount. Programs can be tailored to meet the needs of industrial, commercial and residential customers.
“The great thing about on-bill repayment is that it can serve a broad array of markets with diverse needs,” said Casey Bell, lead author of the report. “It is a versatile financing tool that can be combined with a variety of different sources of capital and implementation strategies.”
ACEEE Executive Direct Steven Nadel said that on-bill financing programs can improve access to energy efficiency funding.
“On-bill financing programs can leverage a utility’s unique relationship with energy customers improving access to funding for energy efficiency investment, especially for historically underserved markets such as rental, multifamily buildings and small businesses,” Nadel said. “There is also potential for traditionally credit-constrained customers to gain access to financing through modified underwriting that takes bill payment history into account.”
Energy efficiency loan programs are a low-risk investment, according to a recent ACEEE report, and on-bill financing is no exception. Default rates for on-bill programs are frequently less than 2 percent. Evidence suggests that customers tend to prioritize the payment of utility bills, which contributes to low default rates, and some program administrators are exploring the potential of bundling on-bill loans with other financial products and creating a secondary market for capital. Creating a secondary market could help bring programs to scale because many of these programs have participation rates of less than 1 percent of eligible customers.
On-bill programs are still generally in their infancy. These programs are facing some challenges to adoption and scalability, including funding the upfront costs for utilities with a need to modify their billing systems, a perception by some that utilities must behave like a financial institution to participate in on-bill financing, and the need for more information on the performance of energy efficiency financing as an asset class.
“As the number of on-bill programs grows, we anticipate many opportunities to learn from experience,” Bell said.
Important considerations for augmenting and implementing on-bill programs include understanding underlying financial incentives and applicable laws and regulations, as well as how risks are distributed amongst stakeholders.
