Commercial Energy in Rosemont, IL: Electricity & Gas

Rosemont is a small O'Hare-area municipality with an outsized commercial profile — hotels, a convention center, and entertainment venues packed into a compact footprint. That mix makes it a distinctive commercial energy market, especially for hospitality accounts, where energy is a real operating cost and both electricity and natural gas carry significant load.

Utilities in Rosemont

• 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 choice changes

A Rosemont business's bill combines two things. Delivery is the regulated infrastructure — ComEd's wires and Nicor's pipes, the meters, the maintenance, and the emergency response — and it stays with the utility no matter who supplies the energy. Supply is the commodity, and eligible commercial customers can buy it from a licensed competitive supplier instead of the utility's default. Choosing a supplier does not create a second company you call in an outage; ComEd still restores power and Nicor still handles a gas leak. It simply lets a hotel or venue put the supply portion of the bill on a known price and term — useful when energy is a line item leadership watches.

What shapes energy costs here

• Hotels and hospitality dominate — round-the-clock electricity plus heavy natural gas for heat, hot water, and laundry. See hotel energy procurement. Because a hotel runs every hour of every day, its load is steady and sizable, which makes the terms of a supply contract meaningful.
• Convention and entertainment venues have variable, event-driven load. Usage can swing sharply between a packed event day and a quiet one, and larger single meters may be demand-billed — meaning the peak kW during a busy load-in can set a charge that carries even when the calendar is light. See commercial demand charges.
• ComEd/PJM capacity applies to larger accounts, so peak behavior on the grid's highest-load hours feeds a capacity tag (the PLC) that follows the account into future supply cost.
• Gas matters as much as electricity for these accounts. Heating, hot water, and laundry make natural gas a large, seasonal share of the energy budget, so procuring commercial natural gas is not an afterthought — it is often half the conversation.

Contract structure and budgeting for hospitality

Hotels and venues live and die by predictable operating budgets, so the structure of an energy contract often matters as much to them as the price. A fixed price for a defined term locks the supply portion of the bill for that period, which helps a property forecast against room revenue or event bookings. An index or pass-through arrangement moves with the wholesale market instead, trading certainty for exposure. Neither structure promises a lower cost — the choice is really about how much market movement a property is willing to absorb.

Timing deserves the same attention. Default supply resets on the utility's schedule, and an existing supplier contract can slide into evergreen terms if its renewal date passes unwatched — an easy thing to miss in a busy hospitality operation. Because both electricity and natural gas are in play for a Rosemont hotel, coordinating the two renewal windows keeps both commodities on the property's timeline rather than drifting onto terms nobody chose. Reviewing the market in the window before each contract ends is what keeps the decision deliberate.

Getting started

Start by confirming the delivery utilities and checking whether the meter is energy-only or demand-billed. Then gather a recent electric and gas bill, the account and meter numbers, the rate class, and 12 months of usage — a full year is especially helpful for seasonal, event-driven load. Provide a recent electric and gas bill for a Rosemont business (a year of usage helps for seasonal accounts), and the account can be reviewed and priced on matched terms through the procurement process. No savings figure is promised in advance — the aim is a clean, apples-to-apples comparison across both commodities.
