Revenue model

1. Natural Gas Distribution Services: Regulated distribution of natural gas to approximately 300,000 customers. Revenue comes from distribution charges, balance and demand charges, and customer charges approved by the Michigan Public Service Commission. By law, SEMCO cannot profit from the actual cost of gas—it is passed through to customers with no mark-up.
2. Gas Supply Cost Pass-Through: Actual cost of natural gas purchased from suppliers is passed directly to customers. SEMCO earns no profit on gas commodity costs. Prices fluctuate based on market conditions, weather, economic activity, and power generation needs.
3. Regulatory Surcharges: Additional charges including Main Replacement Program (MRP) Charge, Infrastructure Reliability Improvement Program (IRIP) Charge, Facility Improvement Demand Surcharge (FID), and Energy Waste Reduction Charge to fund infrastructure improvements and efficiency programs.
4. Energy Waste Reduction Program Rebates: SEMCO administers rebate programs for residential and commercial customers to promote energy efficiency, funded through the Energy Waste Reduction Charge on customer bills.
