MI HB4093

Natural gas utilities may file infrastructure expansion investment plans with the Public Service Commission to serve unserved or underserved areas, with annual spending capped at $5,000,000 or 25% of the utility's annual pipe replacement spending, whichever is greater.

Infrastructure expansion investment plans must include a 1-year investment projection, proposed cost recovery mechanism, detailed costs and benefits analysis, and a 5-year investment projection for future recovery mechanisms.

The Public Service Commission has 180 days to review and approve, disapprove, or amend filed plans through a contested hearing process, and must evaluate the reasonableness, prudence, and compliance with existing customer attachment program requirements.

Utilities must file annual reconciliation reports comparing actual investments to approved plans; the commission may adjust the recovery mechanism based on actual spending levels, though utilities can recover excess costs if demonstrating reasonableness and prudence.

This section expires 10 years after the effective date, and the bill takes effect 90 days after enactment.
