Public utilities: rates; public service commission issuing a report before approving a rate increase; require. Amends sec. 6a of 1939 PA 3 (MCL 460.6a).

SB 587 requires Michigan's Public Service Commission to submit a detailed report to the House and Senate energy committees before approving any rate increase for gas, electric, or steam utilities. The report must explain the proposed increase, its justification, and expected impact on customers. Committees then have 30 days to hold a public hearing and issue a nonbinding recommendation to the commission. This change applies to all utilities seeking rate hikes and adds a legislative review step before final approval. The bill modifies existing rate approval procedures without altering the core process for utilities to file applications.
