Illinois Office Buildings Energy Market Overview
HVAC represents ~35–40% of commercial office electricity use
Office Buildings operations in Illinois typically use 200,000–5,000,000 kWh/year per month. HVAC and lighting drives the majority of consumption — and it's the load that determines what suppliers will bid and how aggressively. Illinois deregulated electricity in 1997 under the Electric Service Customer Choice and Rate Relief Law
Higher summer cooling costs; moderate winter heating in northern markets
Natural gas usage: Heating in northern climates; minimal in southern states
Electricity Cost Drivers for Illinois Office Buildings
Property manager may not be aligned with building owner's cost interests on energy
Lighting historically 30% — LED retrofits have reduced this significantly in newer buildings Running a competitive quote process — rather than renewing with your current supplier — is the single most reliable way to establish whether you're paying market rates. We do that process at no cost.
Demand charges deserve special attention for Office Buildings facilities. Peak demand is driven by Morning occupancy startup (HVAC pre-cooling + lighting simultaneously).

How Illinois Commercial Rates Apply to Office Buildings
Clarify ownership/management structure before procurement — ensures right party signs
For Office Buildings accounts in Illinois, we typically evaluate:
- Fixed-rate contracts (12–36 months): Best for operations with predictable usage and budget requirements. Typical Illinois range: 8–12 cents/kWh (Chicago metro).
- Indexed contracts: Price tracks a published wholesale index plus a fixed adder. Appropriate for operations with sophisticated energy management and flexible load.
- Block + swing: Lock a base volume at fixed rate, let variance float. Works for Office Buildings accounts with variable production schedules.
Load factor of Moderate — 5-day-per-week occupied pattern influences which structure makes sense. We'll model the options against your actual usage before making a recommendation.
Avoiding Procurement Mistakes in Illinois Office Buildings
Triple-net leases mean tenants bear supply cost but landlord controls procurement
MISO / PJM manages the Illinois wholesale market. Capacity charges from MISO / PJM are a pass-through on commercial bills and can vary year to year — they're not negotiable with suppliers, but they affect total cost projections.
Contract pitfalls to watch: auto-renewal into variable rates, demand charge structures that differ from your utility's base tariff, and early termination fees calculated on remaining contract value rather than a flat fee.
