Itasca, Illinois

Commercial Energy in Itasca, IL: Electricity & Gas

At a glance

Itasca is a DuPage County community known for its corporate campuses and office parks, alongside hospitality and some light industrial. Those account types — multi-tenant office buildings, single-tenant corporate headquarters, hotels, and warehouses tucked into business parks off the I-290/I-355 corridor — tend to carry the kind of steady, sizable load where how you buy energy actually shows up on the bill. For large office and campus accounts, commercial energy procurement and demand analysis are worth a careful look.

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.

Account Local utility context What to verify
Electricity ComEd Meter, tariff/rate code, current supply arrangement, measured and billed demand
Natural gas Nicor Gas Delivery utility, gas rate class, program eligibility, therms and supplier contract

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.

Keep the warehouse and office assumptions visible

An Itasca operation occupying both office and warehouse space should establish whether each area is separately metered. Office cooling, warehouse heating, and operating equipment can have different seasonal patterns. A single average rate does not reveal which part is driving the bill.

If several nearby buildings are managed together, inventory their meters before seeking one procurement schedule. Confirm account ownership, service utility, and existing contract dates for each. A common signature date does not mean the supplier can start every account on the same day or transfer every meter into the same product.

Account review steps

  1. Identify separate office, warehouse, and external lighting meters.
  2. Ask whether every account can share the proposed start month.
  3. Retain the cost of bridging a short contract gap as a separate assumption.

Worked Energy Desk example

Suppose one electric meter costs $2,560 in the entered month and a separate gas meter costs $880. The multi-location planner totals $3,440 per month and displays a $41,280 annualized run rate. That is the sum of the entries multiplied by twelve; seasonal heating or cooling can make actual annual spend different.

Use one row per account, keep unknown contract dates blank, and avoid entering a combined site total again as another meter. Grouping does not establish eligibility for one supplier contract.

Utilities in Itasca

  • 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 Customer Select. 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

Every commercial energy bill in Itasca 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 part does not change no matter who supplies your energy, and its rates are set through the Illinois Commerce Commission. Supply is the commodity itself: the electricity and the gas molecules. 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.

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. What a supplier contract does is fix 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 an office park or corporate campus, that predictability is frequently the whole point.

What shapes energy costs here

  • Corporate campuses and office parks — large accounts are often demand-billed; see commercial real estate energy procurement for the portfolio angle across a multi-building or multi-tenant footprint.
  • Office and campus HVAC makes demand charges a common cost driver. Demand is billed on the peak kW an account pulls in a billing period, so a single hot afternoon when chillers and rooftop units 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 (the PLC) that follows the account into its future supply cost. That is why peak management is a supply-cost question, not just a delivery one.
  • Seasonality cuts both ways. Office cooling drives summer electric peaks, while hospitality and any account with real heating or hot-water load sees natural gas rise through winter — which is why gas is worth procuring alongside electricity for hotels and restaurants.

Contract structure and who holds the account

In multi-tenant office parks — common in Itasca — an early question is simply who holds the meter and the utility account: the building owner, a property manager, or the tenant. That determines who can sign a supply contract and how costs flow through a lease. Where a landlord procures for common areas and tenants hold their own meters, the two can be handled separately or coordinated, which is part of the commercial real estate angle.

Supply contracts also come in different structures — most commonly a fixed price for a set term, or an index/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.

Getting started

The most useful first step is simply 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's meaningful gas load, a recent gas bill.
  2. For large or demand-billed accounts, gather 12 months of usage and the 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 an Itasca business (12 months of usage helps for large accounts), and the account can be reviewed and priced on matched terms through the procurement process. No savings figure is promised in advance — the goal is a clear, apples-to-apples comparison and a contract structure that fits how the building actually runs.

Practical answers

Questions you may have

Which utilities serve Itasca businesses?

Electricity delivery is ComEd and natural gas delivery is Nicor Gas. Both serve commercial customers and both allow eligible businesses to choose a competitive supplier. Confirm the utilities on a recent bill for a specific address.

What kinds of Itasca accounts benefit from procurement?

Itasca is a DuPage community known for corporate campuses and office parks, along with hospitality and some light industrial. Large office and campus accounts are often demand-billed and benefit from supply comparison plus demand analysis; hotels and restaurants also carry natural gas load worth procuring.

Does switching suppliers affect service in Itasca?

No. ComEd remains the electricity delivery utility and Nicor remains the gas delivery utility, handling wires, pipes, meters, and emergencies regardless of the supplier. Only the supply portion of the bill changes with a supplier contract.

How does supplier choice actually work in ComEd territory?

Eligible commercial customers can either stay on ComEd's default supply service or sign a supply contract with a licensed Alternative Retail Electric Supplier (ARES). Either way, ComEd continues to own the wires, read the meter, send the bill, and respond to outages. The supplier only sets the price of the supply (energy and capacity) portion. The Illinois Commerce Commission licenses ARES and publishes consumer basics through its Plug In Illinois resource.

What should Itasca businesses prepare for an account review?

Identify separate office, warehouse, and external lighting meters. Ask whether every account can share the proposed start month. Retain the cost of bridging a short contract gap as a separate assumption. Use the linked Energy Desk example as a planning illustration and confirm the account-specific tariff and contract.
