Utility Rate Increase Revenue Disclosure (HB6131)

Current understanding

HB6131 would amend Sec. 6a of 1939 PA 3 (MCL 460.6a) to require public utilities to disclose how they intend to use increased revenue when filing rate increase requests with regulators. The bill is an incremental transparency measure layered onto the existing MPSC rate case process rather than a new ratemaking mechanism. Status: introduced.
