Illinois Solar for All (ILSFA) has published the total 2025-2026 program year budgets for the Illinois Solar for All: Residential Solar and Illinois Solar for All: Non-Profit and Public Facilities sub-programs. The Illinois Solar for All: Community Solar sub-program rollover budget will be shared in the coming weeks.
The sub-program budget amounts are prorated across the sub-programs according to the Renewable Energy Resources Fund (RERF) allocation percentage under the law. As described in the 2024 Long-Term Renewable Resources Plan (2024 Long-Term Plan) and implemented previously in the 2024-2025 program year, the Illinois Power Agency (IPA) will hold the initial 50% budget allocations for the Illinois Solar for All: Residential Solar (Small and Large) sub-programs on a first-come, first-serve basis for the first nine months of the program year. After March 1, 2026, the two sub-program allocations will combine to be used on a first-come, first-served basis by projects of either sub-program.
Twenty-five percent of funds in each sub-program category will be reserved for energy sovereignty projects to promote ownership for eligible customers, and twenty-five percent for projects sited in an environmental justice community (EJC). These twenty-five percent carve-outs will not be earmarked for RERF or utility funding. As described in Section 8.5.1.2 and 8.5.3 of the 2024 Long-Term Plan, and updated in April 2025, initial Energy Sovereignty carveout allocations for all sub-programs will be held for six months after the corresponding sub-program’s application window opening. All EJC carveouts are held for the full year. Any unused EJC carveout funds at the end of the program year would roll over to the same sub-program’s budget in the next program year.
As implemented previously in the 2024-2025 program year, the IPA will roll over funds from reductions in final REC Contract values to the same sub-program budget with any other unallocated funding, per Section 8.10.2 of the 2024 Long-Term Plan. Any funds made available from reductions in final REC contract values will be rolled over to the same sub-program budget the following year. Further details can be found in the Approved Vendor Manual for the 2025-2026 program year, which was updated on June 1, 2025.
