Commercial Real Estate Energy Procurement in Illinois
Last reviewed: 7/31/2026
By Illinois Commercial Energy editorial team · Reviewed by JakenEnergy commercial energy team
Commercial real estate — office buildings, shopping centers, and multi-tenant properties — is a portfolio energy problem more than a single-account one. For Illinois owners and property managers, the value comes from organizing many meters across buildings, utilities, and renewal dates into a coordinated procurement.
Who this is for
Owners, asset managers, and property managers responsible for energy across Illinois commercial buildings and portfolios — office, retail, mixed-use, and multi-tenant. It applies whether the owner holds one large building or many.
The commercial real estate energy picture
- Common-area vs. tenant accounts. Owners typically control common-area meters (lobbies, garages, HVAC, exterior); tenant spaces may be separately metered. Procurement focuses on the accounts the owner controls — start with a meter inventory.
- Multiple utilities and dates. A portfolio can span ComEd and Ameren electric and different gas utilities, each with its own market and renewal timing.
- Larger buildings are often demand-billed, making demand charges relevant for common-area accounts with big HVAC loads.
Portfolio procurement, not single-rate shopping
The core work mirrors multi-location procurement: inventory every meter (utility, rate class, current supplier, end date), group accounts correctly, align delivery dates where it helps, and maintain a renewal calendar. A cross-portfolio bill review frequently surfaces inconsistent rate classes and contract statuses between buildings.
Getting started
Provide a meter/account inventory and recent bills for the owner-controlled accounts, and the portfolio can be grouped, reviewed, and priced group by group through the procurement process. No savings figure is promised in advance.
Frequently Asked Questions
QWhat is distinctive about energy procurement for a property portfolio?
Property portfolios combine many meters across buildings — common-area accounts the owner controls, and sometimes tenant accounts — often spanning different utilities and renewal dates. The work is less about a single rate and more about inventorying meters, grouping them correctly by utility, and coordinating renewals so no account rolls to a holdover rate.
QWho pays for energy in a commercial building — owner or tenant?
It depends on the lease and metering. Common areas are usually the owner's account; tenant spaces may be separately metered and billed to tenants, or included in the lease. Procurement focuses on the accounts the owner controls, and a clear meter inventory is the starting point for any portfolio.
QCan a real estate portfolio align its energy renewals?
Often, yes. Accounts within the same utility can frequently be grouped for a common delivery date, which simplifies management. Portfolios spanning ComEd and Ameren electric or different gas utilities become a few coordinated groups with a shared renewal calendar rather than one contract.
