Today Slipstream announced that its clean energy financing division, Energy Finance Solutions (EFS), has facilitated over $1 billion in loans to fund energy efficiency and renewable energy upgrades for homes and businesses, including thousands of homeowners with low-to-moderate incomes.

For over 25 years, EFS has helped customers overcome cost barriers to energy-saving improvements by connecting them with affordable financing services that can save energy, lower monthly utility bills, and provide reasonable repayment options. This work has been made possible through partnerships with a variety of state and local governments, utilities, and like-minded organizations in regions spanning from New York state to Hawaii.

"The success of Slipstream’s Energy Finance Solutions team in surpassing $1 billion in loans has been supported by the strong partnership with NYSERDA's Green Jobs Green New York (GJGNY) Residential Home Loan Program," said Doreen M. Harris, President and CEO of the New York State Energy Research and Development Authority (NYSERDA). "Through these loans, NYSERDA and Slipstream have brought energy-efficient upgrades to homeowners across New York, and we look forward to continuing our work together to make financing these improvements more accessible."

NYSERDA is one of several state agencies, utilities, and municipalities who partner with EFS to offer financial services such as on-bill financing (OBF), on-bill repayment (OBR), and direct bill financing. EFS currently serves customers in Minnesota, Illinois, Delaware, New York, and New Jersey. The $1 billion milestone includes a history of EFS programs in 22 total states.

Since its first loan, EFS has helped provide financing for over 92,000 households. With an average loan amount of $9,000, the energy efficiency upgrades enabled by EFS represent everything from installations of air-source heat pumps and solar panels to comprehensive, whole-home retrofits designed for income-qualified customers. Along with saving energy, such measures have the potential to improve a building's comfort and indoor air quality, increase a home’s long-term value, and protect residents from the accelerating impacts of climate change such as rising temperatures.

"Our EFS division is central to our mission to ensure that everyone can access the economic and financial benefits of energy efficiency in their homes and businesses," said Sandra Henry, President and CEO of Slipstream. "Too often, the only thing standing between a low-income household and a much-needed upgrade is the right kind of financing. Our EFS programs make it more likely they'll see an affordable option come across their kitchen table."

Starting August 27, Slipstream is honoring this legacy by Celebrating $1 Billion in Change. Visit slipstreaminc.org/1billion to hear stories from the history of EFS and learn more about EFS programs—including our innovative loan origination system, VelocityGO.
