Restaurant Energy Procurement in Illinois
Last reviewed: 7/31/2026
By Illinois Commercial Energy editorial team · Reviewed by JakenEnergy commercial energy team
Restaurants are a two-commodity energy account: significant natural gas for cooking and hot water, and steady electricity for refrigeration, HVAC, and lighting. For Illinois food-service operators — from Chicago independents to suburban groups and franchises — procuring both well protects a real margin line.
Who this is for
Owners, operators, and controllers of Illinois restaurants and restaurant groups. Single sites benefit from a bill review; multi-unit groups and franchises benefit most, because accounts can be grouped and renewals coordinated.
The restaurant load profile
- Heavy natural gas for cooking lines and water heating — often the larger energy line for a full-service kitchen. The gas utility depends on location: Peoples Gas in Chicago, Nicor in most suburbs.
- Steady electricity for walk-in refrigeration, HVAC, exhaust, and lighting, with long daily operating hours.
- Usually a favorable, steady load shape, though larger operations may hit demand-billed thresholds.
Both commodities deserve attention
Because gas is such a large share of a kitchen's energy, procuring commercial natural gas matters as much as electricity. Confirm the gas utility from a recent bill first, since the territory determines how (and whether) supplier choice applies.
Groups and franchises
Multi-unit operators are best handled as a grouped multi-location procurement, aligning renewals and grouping by utility. A bill review across the fleet often surfaces inconsistent rate classes or contract statuses between locations.
Getting started
Provide a recent electric and gas bill per location (a year of usage helps), and the account or group can be reviewed and priced on matched terms through the procurement process. No savings figure is promised in advance.
Frequently Asked Questions
QDo restaurants use more natural gas or electricity?
It varies, but most full-service restaurants carry significant natural gas load for cooking and water heating, plus meaningful electricity for refrigeration, HVAC, and lighting. Because both commodities matter, restaurants benefit from procuring gas and electricity, not just shopping one. The gas utility depends on location — Peoples Gas in Chicago, Nicor in most suburbs.
QIs a single restaurant large enough to bother with procurement?
A single independent restaurant is often a smaller account, but energy is a real margin item in food service, and a bill review can still confirm the rate class, contract status, and whether demand charges apply. Restaurant groups and franchises with multiple Illinois locations gain more, since accounts can be grouped and renewals aligned.
QWhat should a restaurant have ready to get pricing?
A recent electric and gas bill per location, the service address and utilities, and roughly a year of usage. Because kitchens run long hours, the usage pattern is usually steady, which helps pricing — but confirming the utilities (especially gas) from a recent bill is the first step.
