Solar Bridge Loans

Interim Financing for Projects Awaiting Tax Credits and/or State Incentives

Program Overview

  • Solar bridge loans, funded by congressionally approved and lawfully awarded funds from U.S. DOE’s Energy Efficiency Revolving Fund (EERF) and the U.S. EPA’s National Clean Investment Fund (NCIF), provide short-term financing to cover the period between funding a solar project and receiving federal tax credits (including elective pay), renewable energy credits (RECs), or other financial incentives. These loans help ensure that solar providers and customers can move forward with projects without waiting for tax credits, U.S. Treasury payments, Illinois Solar for All incentives, Illinois Shines incentives, or utility payments. While we expect that solar and battery storage installations will be the most popular use of this loan, geothermal, energy efficiency, and other clean energy upgrades may also be eligible.
  • The Energy Efficiency Revolving Loan Fund provides flexible financing solutions to support energy efficiency and clean energy projects in Illinois. The program offers Bridge Loans to cover gaps between project completion and disbursement of federal or state incentives and Co-Lending/Participation Loans to support longer-term project financing. The fund is administered by the Illinois Finance Authority (IFA) and capitalized through a grant from the U.S. Department of Energy.
  • Bridge Loans offer interim financing for entities awaiting Direct Pay tax credits, Investment Tax Credits (ITC), or incentives through Illinois Solar for All. These short-term loans allow projects to move forward without financial delay.
  • Eligible projects must be commercial buildings, including multifamily buildings with five or more units located in Illinois, that have undergone a qualified energy audit.
  • The program has specific requirements related to building assessments and program outcomes. For full program details, summary loan terms, and eligibility requirements, refer to the EE RLF Initial Bridge Loan Strategy.

Funding & Eligibility

  • This program is a $14 million revolving loan fund that will offer loans of up to $1 million each for a short term (12-18 month) and, in some instances, more lengthy participation loans.
