Under the state's Climate and Equitable Jobs Act, net metering benefits for new renewable energy customers will change effective January 1, 2025. The primary change is new net metering customers will receive only supply and transmission service credits for excess generation pushed to the grid. This change will still allow new net metering customers to receive reduced bills from Ameren due to their generator's output replacing the electricity they would have otherwise pulled from Ameren's system.
However, there's still time for customers to receive the current net metering benefits. Residential and small non-residential customers who have generation installed and all documentation submitted to Ameren Illinois by 5 p.m. on December 31, 2024 will receive full netting for the 30-year life of their generator.
Note: Existing Ameren Illinois solar customers WILL NOT see any changes to their net metering. If you currently receive net metering benefits for your solar panels, you will not be affected by the upcoming changes in 2025 unless you make a significant size increase to your system or you apply for a generator rebate.
For current solar customers with net metering, nothing will change. Their benefits are locked in for the life of their equipment. They will continue to receive credits on their bill for any excess power pushed back to the grid, assuming they don't receive a rebate for the smart inverter connected to their generation. Note: The only other way existing customers could see changes to their net metering benefits is if they significantly increase the size of their system.
Beginning January 1, 2025, under Illinois law, residential and small non-residential customers who complete installation of solar at their premises on or after this date will still receive net metering benefits, but credits for any excess generation pushed to the grid will only be applied to the supply and transmission portions of their bill rather than the total bill.
