Peoples Gas Commercial Natural Gas Service (Chicago)
Peoples Gas is the natural gas delivery utility for the City of Chicago. This guide covers how commercial gas service works within the city, where supplier choice applies, and what a Chicago business needs to price gas. For the statewide view, see commercial natural gas in Illinois.
Territory
Peoples Gas Light & Coke Company serves the City of Chicago. Just outside the city, gas service is generally Nicor Gas, and parts of Lake County and the far north suburbs are North Shore Gas. For any address near the city boundary, the utility name on the bill is the reliable confirmation.
Supply vs. delivery
On Peoples Gas utility service, the gas supply is passed through as a purchased-gas cost that adjusts over time; the delivery charge covers the utility's distribution system, metering, and applicable riders and taxes. A supplier contract prices the supply portion only. Chicago commercial bills can carry a meaningful delivery component, so a supply change moves only part of the total.
Commercial supplier choice
Through the Choices for You program, eligible Chicago commercial customers can buy gas supply from a licensed alternative gas supplier while Peoples Gas continues delivery and emergency service. Evaluate any offer with the same procurement and contract review discipline used for electricity — matched terms, included components, and renewal language, not headline price alone.
What a Peoples Gas commercial quote requires
- A recent Peoples Gas bill and account number.
