IBank’s California Lending for Energy and Environmental Needs (CLEEN) program provides low-cost direct public financing to local governments and nonprofits sponsored by public agencies to help meet the state’s goals for greenhouse gas reduction, water conservation, and environmental preservation


The CLEEN Center offers two programs: the Statewide Energy Efficiency Program (SWEEP) and the Light Emitting Diode Street Lighting (LED) program.

Financing can be through a direct loan from IBank or through publicly offered tax-exempt bonds in amounts from $500,000 to $30 million.


With IBank you:

• Save time — We conduct a preliminary review process and provide feedback before inviting you to apply.
• Can submit applications any time of the year. We accept applications continuously, and because we issue our own bonds to generate funds, we do not run out of funding.
• If approved, can receive funds within 45 to 90 days of IBank board approval.
• Receive low-, competitive, fixed-interest rates up to 30 years. We are AAA rated, and we pass our low borrowing costs (through bonds) to you.
• Don’t have to compete against others — No scoring mechanisms, we operate on a first-come, first-served basis.
• Get transparency every step of the way — No surprises.

IBank is part of the solution addressing climate change by financing and supporting innovative climate and clean-energy projects that create a better California for all.

We are experts in municipal lending and our loan team values access to opportunity, diversity, and inclusion and truly cares about connecting city and other local governments to the low-cost financing they need to make their important public infrastructure and economic expansion projects a reality.
