This report “Status of Renewable Energy, Distributed Generation, and Legacy Net Metering in Michigan” by The Michigan Public Service Commission provides information on renewable energy activities involving the Michigan Public Service Commission (Commission or MPSC) through calendar year 2023 and summarises data from electric provider 2023 annual reports and the contract summary. Additionally, this report shows renewable energy projections through 2026 based on the renewable portfolio standard (RPS), voluntary green pricing programs (VGP), integrated resource plans (IRPs), public utility regulatory policies act (PURPA) resources, and the distributed generation and legacy net metering programs.
There have been significant legislative changes that will transform Michigan’s electric generation portfolio in the coming years. Public Act 235 of 2023 (PA 235) requires electric providers to maintain a renewable portfolio requirement of 15% through 2029, 50% from 2030 through 2034, and finally achieve a 60% renewable portfolio in 2035 and each year thereafter. In addition, PA 235 increases the distributed generation program requirement for rate regulated electric providers and alternative electric suppliers (AES) from 1% of average in-state peak load to 10%. Some rate-regulated electric providers had voluntarily increased their programs prior to this requirement, but none had reached 10% as is now legislatively required.
