Establishes tiered residential credit rates based on outage duration: $5 for the first hour, $7/hour for 1-5 hours, $10/hour for 5-12 hours, $12/hour for 12-24 hours, $15/hour for 24-48 hours, $18/hour for 48-72 hours, and $25/hour for outages of 72 hours or more

Directs the Public Service Commission to establish within 12 months a formula for nonresidential customer credits based on outage hours multiplied by the customer's average hourly load

Requires the commission to adjust credit amounts every 5 years based on changes in the Detroit-Warren-Dearborn Consumer Price Index, with adjustments rounded up to the nearest dollar

Takes effect only if House Bill 4974 or Senate Bill (S00500'25) of the 103rd Legislature is also enacted into law
