Commercial Energy in Lombard, IL: Electricity & Gas

Utility and supplier-choice checkpoint

The utilities below are local service context, not an address-level eligibility guarantee. Confirm the current bill, service address, account holder, and rate class before requesting a change.

Electricity: Eligible ComEd-served business accounts can compare retail electric supply while ComEd continues delivery. Use the ICC’s electric-choice explanation and the account’s ComEd tariff and rate class. Keep supply, delivery demand, and capacity inputs separate.

Natural gas: Nicor lists this community in its service territory. For a Nicor business account, Customer Select is the relevant supplier-choice program. Check current eligibility, supplier fees, billing arrangements, and applicable utility charges and credits.

Supplier selection affects the supply arrangement. It does not replace the delivery utility or its infrastructure and emergency responsibilities. A change in supplier does not guarantee a lower total bill.

Use a matching period before comparing neighboring suites

A Lombard business comparing its bill with another suite should first check whether both figures cover the same number of days and the same cost components. One statement may include supplier charges while another contains delivery only. A total-bill average is not automatically a supply rate.

For a retail unit alongside office space, opening hours and equipment can also differ substantially. Start with the account’s own two bills and separate usage, supply-price, demand, and other line-item changes. Then use a complete annual forecast to compare proposals, keeping unrelated lease charges outside the supplier calculation.

Account review steps

1. Match the supplier invoice to the utility billing period.
2. Compare daily consumption as well as monthly consumption.
3. Check whether a quoted cents-per-kWh figure excludes delivery.

Worked Energy Desk example

Suppose a 30-day electric bill shows 15,000 kWh at 8¢/kWh, followed by a 30-day bill showing 17,000 kWh at 9¢/kWh. Enter the bill line items in the bill change analyzer. The usage effect at the previous price is $160; the price effect on current consumption is $170. Supply cost therefore rises by $330 before demand and other charges.

Enter delivery, adjustments, taxes, and other amounts in their proper fields to reconcile the modeled totals to both bills. The model separates arithmetic effects; it does not weather-normalize the account or establish why equipment used more energy. These are illustrative inputs, not local utility rates, supplier quotes, or promised savings.

Utilities in Lombard

• Electricity: ComEd is the delivery utility, with commercial supplier choice available. See the ComEd commercial guide.
• Natural gas: Nicor Gas is typically the delivery utility, with commercial supplier choice available. Confirm the gas utility on a recent bill. See the Nicor Gas commercial guide.

The delivery utility continues delivery and emergency service when a business chooses a competitive supplier. Confirm both utilities from a recent bill for a specific address, since gas territory can vary.

Supply versus delivery: what choice changes

Every commercial energy bill in Lombard is really two bills stacked together. Delivery is the regulated part — the poles, wires, pipes, meters, maintenance, and emergency response that ComEd and Nicor Gas provide. That portion does not change no matter who supplies the energy, and its rates are set through the Illinois Commerce Commission. Supply is the commodity itself: the electricity and the gas. In ComEd and Nicor territory, eligible commercial customers can choose to buy that supply from a licensed competitive supplier instead of taking the utility's default supply service. The mechanics are laid out in how Illinois commercial electricity choice works and how commercial natural gas choice works in Illinois.

Choosing a supplier does not create a second company that shows up when the lights go out. ComEd still restores power; Nicor still handles a gas leak. A supplier contract fixes the price and terms of the supply portion — often for a set term — so a business can plan around a known rate instead of riding the utility's default price, which resets periodically. For a retail center or office building, that predictability is often the whole point.

What shapes energy costs here

• Account type and rate class. A small storefront billed on energy alone reads very differently from a large retail center or office building that is demand-billed. The rate class on the bill is the first thing to check because it changes the entire analysis.
• HVAC and refrigeration peaks make demand charges a common cost driver for larger accounts. Demand is billed on the peak kW an account pulls in a billing period, so an afternoon when rooftop units, refrigeration, and equipment all run at once can set a charge that carries regardless of total kilowatt-hours used.
• ComEd/PJM capacity matters for larger accounts. Northern Illinois sits in the PJM market, and an account's peak-demand behavior on the system's highest-load hours feeds a capacity tag that follows the account into future supply cost. That makes peak management a supply-cost question, not only a delivery one.
• Seasonality cuts both ways. Retail and office cooling drive summer electric peaks, while restaurants, hotels, and any account with real heating or hot-water load see natural gas rise through winter — which is why gas is worth procuring alongside electricity.
• Tenancy in retail and office space. In multi-tenant centers, common along Lombard's corridors, an early question is who holds the meter and the utility account: the property owner, a manager, or the tenant. That determines who can sign a supply contract and how costs flow through a lease, and it can mean common-area and tenant accounts are handled separately or coordinated.

Contract structure and renewal timing

Supply contracts come in different structures — most commonly a fixed price for a set term, or an index or pass-through arrangement that moves with the market. The right fit depends on how much budget certainty an account wants versus its appetite for market movement, and on when the current contract or default-service period ends. Watching that renewal window matters: default supply resets on its own schedule, and existing supplier contracts can roll into less favorable evergreen terms if a renewal date passes unmanaged. Knowing the end date is what keeps a decision on your timeline rather than the utility's or an incumbent supplier's. You can see the broader flow in the commercial electricity and commercial natural gas overviews.

Getting started

The most useful first step is reading the bill. Confirm the delivery utilities, note the rate class, and check whether the account is energy-only or demand-billed — that one detail changes the whole analysis. From there:

1. Pull a recent electric bill and, where there is meaningful gas load, a recent gas bill so the gas utility is confirmed.
2. For large or demand-billed accounts, gather 12 months of usage and peak-demand history so seasonality and capacity exposure can be seen clearly.
3. Note any upcoming lease changes, expansions, or equipment additions that could shift load.

Provide a recent electric and (where applicable) gas bill for a Lombard business, and the account can be reviewed and priced on matched terms through the commercial energy procurement process. No savings figure is promised in advance, and no specific outcome is guaranteed — the goal is a clear, apples-to-apples comparison and a contract structure that fits how the business actually runs.
