House Bill 5927 would substantially revise Michigan’s distributed generation and rooftop solar rules under the Clean and Renewable Energy and Energy Waste Reduction Act. It directs the Public Service Commission to create a separate rooftop solar net metering program and removes eligible rooftop solar generators from the general distributed generation program after the new section takes effect. The bill sets statewide standards for interconnection, application forms, approval timelines, billing credits, and consumer disclosures for rooftop solar customers served by electric utilities and alternative electric suppliers.
The bill requires monthly netting and full retail bill credits for exported rooftop solar electricity, including major per-kilowatt-hour charges and riders, with credits carried forward for at least 12 billing periods and then paid out at the retail rate. It also limits utilities from imposing standby charges, demand charges, minimum bills, extra fixed charges, interconnection fees, or insurance requirements solely because a customer participates, except for a one-time cost-based application fee approved by the commission. The bill further allows systems sized up to 120% of prior-year usage, establishes 10-business-day and 20-business-day approval deadlines depending on system size, and deems late applications approved.
The bill also changes the broader distributed generation program by capping participation at 10% of a utility’s average in-state peak load over the prior five years, allocating that capacity between smaller and larger systems, and requiring first-come, first-served selection. It preserves utility authority to test and approve interconnections, requires compliance with electrical and construction codes, and allows the commission to require grid-balancing inverter functions if needed for reliability or safety. Utilities and alternative suppliers must keep records of applications and active generators, and the commission must update rules within 180 days of enactment.
In terms of state law impact, HB 5927 would add a new statutory rooftop solar net metering section and narrow the scope of the existing distributed generation program for rooftop solar participants. It would also expand the Public Service Commission’s rulemaking duties, impose reporting and dashboard requirements on utilities, and create civil fines of up to $1,000 per day for missed interconnection deadlines. The bill would affect electric utilities, alternative electric suppliers, rooftop solar customers, and the PSC by standardizing interconnection and compensation rules statewide.
The available context shows no recorded committee testimony or votes, so there is no documented public debate in the provided materials. Based on the bill text, the measure appears designed to strongly support rooftop solar adoption and consumer protections, while also preserving utility oversight and some reliability safeguards. The main likely points of contention are the requirement for full retail credits, the prohibition on many utility charges, the 20-year grandfathering protection, and the mandatory approval timelines, which could be viewed by utilities as limiting cost recovery and operational flexibility, while solar advocates would likely support them as necessary to ensure fair access and stable compensation.
HB 5927 would amend Michigan’s existing clean energy law to create a separate rooftop solar net metering framework and to modify the state’s distributed generation program so rooftop solar participants are governed by the new section instead of the general distributed generation rules. It would require the Public Service Commission to adopt statewide uniform interconnection, billing, and consumer-protection rules, and it would impose new utility reporting, dashboard, and compliance obligations. The bill would also authorize civil penalties for missed approval deadlines and would affect the rights and obligations of electric utilities, alternative electric suppliers, and residential and other retail customers installing rooftop solar systems.
No committee transcripts or votes were provided, so there is no direct record of debate, support, or opposition in the supplied materials. The bill’s structure suggests a pro-solar, consumer-protection-oriented approach, with strong support likely from rooftop solar advocates and customers seeking predictable credits and faster interconnection. At the same time, the bill’s detailed limits on utility charges, mandatory retail-rate credits, and strict timelines suggest it could draw concern from utilities and others focused on cost allocation, grid management, and ratepayer impacts.
The most likely points of contention are the bill’s requirement that exported rooftop solar receive full retail-rate credits, the prohibition on standby, demand, minimum, and other fixed charges, and the 20-year nonrollback protection for existing crediting terms. Utilities may also object to the deemed-approved application deadlines, the civil fines for missed timelines, and the restriction on allocating broader system upgrade costs to individual customers. Supporters would likely emphasize consumer certainty, statewide consistency, and reduced barriers to rooftop solar adoption, while opponents would likely focus on cost recovery, grid reliability, and administrative burden.
