Hotel & Hospitality Energy Procurement in Illinois

Hotels run 24 hours a day and carry both significant electricity and significant natural gas load, which makes them a distinctive commercial energy account. For Illinois hospitality — from downtown Chicago and O'Hare/Rosemont convention properties to suburban and highway hotels — procuring both commodities well matters, and doing it well means understanding how a hotel actually uses energy across a day, a week, and a year.

Who this is for

General managers, directors of engineering, controllers, and ownership groups for Illinois hotels and hospitality properties. Convention-driven markets (downtown Chicago, Rosemont near O'Hare) and suburban clusters have different usage patterns, and both benefit from account-specific procurement. Full-service properties with restaurants, banquet kitchens, pools, and on-site laundry carry more gas load than a limited-service exterior-corridor hotel, and that mix shapes which commodity deserves the most attention.

The hotel load profile

• Electricity around the clock. Guest rooms, corridors, common areas, HVAC, elevators, kitchens, and pool/spa equipment produce a steady baseload that never fully drops off, with occupancy-driven swings on top of it. A near-full house on a hot convention weekend runs far more cooling and elevator load than the same property mid-week in shoulder season.
• Heavy natural gas. Space heating, domestic hot water for showers and kitchens, laundry, and cooking make gas a large share of the energy budget. The gas utility depends on location: Peoples Gas in Chicago, Nicor in most suburbs, North Shore Gas in parts of Lake County. Hot-water demand is fairly steady year-round, while space heating adds a strong winter peak — so a hotel's gas usage typically has both a baseload and a sharp seasonal shape.
• Occupancy and seasonality. Usage tracks occupancy and season, which matters for contract volume-tolerance terms. A property whose business swings with a convention calendar or a summer-travel season will see months that run well above and below its average, and a contract has to accommodate that range.

Demand and capacity mechanics

Once a property is large enough to sit on a demand-billed rate class, the electric bill splits into an energy charge (per kWh) and a demand charge based on the single highest kW interval in the billing period. For a hotel, that peak is usually a summer afternoon when chillers and rooftop units are working hardest at the same time elevators and kitchens are busy. Managing that coincident peak is a different task from negotiating the per-kWh rate, and both belong in a full review.

In ComEd's northern-Illinois territory, which sits in the PJM market, a facility also carries a capacity tag (its PLC, or peak load contribution) set by how much it draws during regional system-peak hours. That tag rides into future supply cost, so a hotel's behavior on a handful of high-demand summer days can influence its pricing for the following delivery year. In central and southern Illinois, Ameren sits in the MISO market, where the capacity mechanics differ. A PJM capacity auction clearing price is a wholesale figure, not a rate on anyone's bill — it is one input among many that a supplier reflects in an offer.

Both commodities deserve attention

Because gas is such a large share of hotel energy, procuring commercial natural gas is not an afterthought to electricity — both should be reviewed. Confirm the gas utility from a bill first, since the territory determines whether and how supplier choice applies. Note that in Ameren's downstate gas territory there is no standard small-commercial supplier-choice program; larger accounts there use transportation service (Rider T) instead, which is a different procurement path.

Procurement considerations specific to hotels

Gather a full 12 months of electric and gas bills per property so a term reflects the real seasonal shape rather than a single month. For larger properties, interval data shows the hour-by-hour load shape and reveals where demand peaks fall — useful both for pricing and for deciding whether any demand-management measures are worth pursuing. Contract fit matters too: a hotel with a swingy occupancy calendar wants volume-tolerance terms wide enough that a strong or weak season does not trigger penalties, and a renewal date that does not land in the middle of peak season when attention is elsewhere.

What to watch for

• Rolling to a default rate at expiration. A contract that lapses can revert to a utility default or a holdover supplier rate; a renewal calendar prevents that.
• A renewal date buried in busy season. Aligning renewals to a quieter part of the year keeps the decision from being rushed.
• Assuming one utility fits every property. A portfolio can span ComEd and Ameren for electricity and multiple gas utilities, so confirm each account from its own bill.
• Treating reliability as a supply question. Outage response comes from the delivery utility and on-site backup, never from the supplier — keep that planning separate from the supply contract.

Portfolios and renewals

Hotel groups with multiple Illinois properties usually procure best as a grouped multi-location account, aligning renewals and grouping by utility. Because properties may span two electric utilities and several gas utilities, a portfolio typically becomes a few coordinated groups rather than one contract, and a shared renewal calendar keeps any single property from rolling to a post-expiration rate.

How procurement should approach a hotel

Gather 12 months of electric and gas bills per property, confirm utilities and usage patterns, separate the demand and capacity levers from the supply rate, and price both commodities on matched terms through the procurement process. No savings figure is promised in advance — the value is a correctly classified, correctly priced pair of accounts with renewals under control.
