How SEMCO Energy Gas Company and Retail Suppliers Work Together
SEMCO serves southeastern MI — manufacturing and industrial gas load in the automotive supply chain corridor.
SEMCO handles gas distribution. AES (alternative gas suppliers) compete for commercial supply. The supply portion of your bill — typically the largest single line item for commercial accounts — is where retail competition applies. That's the piece a broker targets.
SEMCO rates are MI PSC-regulated. Natural gas retail competition is available.
What "Switching Suppliers" Means for SEMCO Energy Gas Company Customers
Standard Michigan gas switching process applies in SEMCO territory.
Michigan natural gas retail competition is available for commercial accounts.
The process: you authorize a supplier to serve your account, they notify SEMCO Energy Gas Company, and the change takes effect at your next billing cycle. No technician visit. No service interruption. Same reliability, different supply rate.

Understanding Your SEMCO Energy Gas Company Commercial Bill
A typical commercial SEMCO Energy Gas Company bill has several distinct charges:
- Supply charge: Cost of electricity generation. This is negotiable — it's what retail suppliers compete on.
- Distribution/delivery charge: SEMCO Energy Gas Company's fee for owning and maintaining the wires. Regulated, fixed.
- Transmission charge: High-voltage grid cost, managed by N/A (natural gas). Regulated, fixed.
- Demand charge: Based on your peak 15-minute interval each month. Can represent 30–50% of your total bill.
- Capacity charges: N/A (natural gas) capacity market costs. Pass-through, not negotiable with suppliers.
A broker focuses on the supply charge — the one component where you have leverage. We make sure you understand all other charges so there are no surprises.
