Commercial Energy in Schaumburg, IL: Electricity & Gas

Schaumburg is one of the largest business centers in the northwest suburbs — corporate offices, a major retail and convention presence, hotels, and restaurants. It's the kind of market where a single address might be a multi-tenant office tower, a big-box store, or a full-service restaurant, and each reads the energy bill a little differently. For those commercial accounts, procuring electricity and natural gas well starts with knowing the utilities and reading the bill.

Utilities in Schaumburg

• Electricity: ComEd is the delivery utility, with commercial supplier choice available. See the ComEd commercial guide.
• Natural gas: Nicor Gas is the delivery utility, with commercial supplier choice through Choices for You. See the Nicor Gas commercial guide.

Confirm both utilities from a recent bill. The utility continues delivery and emergency service when a business chooses a supplier.

Supply versus delivery: what a bill really contains

Every commercial bill in Schaumburg is two things at once. Delivery is the regulated service ComEd and Nicor provide — wires, pipes, meters, maintenance, and emergency response — and it doesn't change with the supplier. Supply is the commodity itself, the electricity and gas, and that is the part a licensed competitive supplier can price. Reading the bill to see where delivery ends and supply begins is the first practical step, because only the supply portion is up for comparison. Confirming the rate class and whether the meter is energy-only or demand-billed comes next — those details decide what kind of analysis is even relevant.

What shapes energy costs here

Schaumburg's account mix is more office/retail/hospitality than heavy industrial, which shifts the priorities:

• Office and retail accounts benefit most from clean supply comparison and a bill review to confirm rate class and contract status. Steady weekday load makes these accounts well-suited to a straightforward supply comparison.
• Hotels and restaurants carry meaningful natural gas load for heat, hot water, and kitchens — gas procurement matters alongside electricity, and its winter seasonality makes contract timing worth attention.
• Larger single meters — big-box retail, office towers, and anchor tenants — may be demand-billed, making demand charges relevant. Demand is billed on the peak kW an account pulls in a period, so a summer afternoon when rooftop cooling runs flat out can set a charge regardless of total kilowatt-hours.
• ComEd/PJM capacity applies to larger accounts: because northern Illinois is in the PJM market, peak behavior feeds a capacity tag (the PLC) that carries into future supply cost, giving peak management a second payoff beyond the demand line.

Contract structure and renewal timing

Once the utilities and rate class are confirmed, the decisions that matter are structure and timing. Supply comes most often as a fixed price for a set term, which locks the supply portion of the bill and helps an office or retailer budget with certainty, or as an index/pass-through arrangement that moves with the wholesale market and trades certainty for flexibility. The right fit depends on the account's load profile and how much market movement the business is willing to carry — neither structure is inherently cheaper, and none should be sold as such.

Timing is where many accounts quietly lose ground. Default supply resets on the utility's own schedule, and an existing supplier contract can roll into evergreen terms if its renewal date passes unmanaged. That is why a bill review checks not just the rate class but the contract status and end date. Knowing when an agreement expires — and reviewing the market in the window beforehand — keeps a Schaumburg business making the call on its own timeline rather than defaulting into terms it didn't choose. For multi-site retailers or office operators, aligning those dates across locations turns scattered renewals into a single, manageable calendar.

Getting started

Begin by reading a recent bill to confirm the utilities, the rate class, and whether the account is demand-billed. Then gather the account and meter numbers, any current supplier contract end date, and — for larger accounts — 12 months of usage and peak-demand history. Provide a recent electric and (where applicable) gas bill for a Schaumburg business, and the account can be reviewed and priced on matched terms through the procurement process. No savings figure is promised in advance; the point is a clear comparison and a contract that matches how the business runs.
