Illinois Commercial Energy Contract Renewal Timeline
By Illinois Commercial Energy editorial team
Reviewed by JakenEnergy commercial energy team
The most avoidable cost in Illinois commercial energy is letting a contract lapse into a holdover or auto-renewal rate. The fix is a timeline: know the end date, know the notice window, and act early enough to have real options.
The renewal timeline
- 6 months out: locate the executed contract, confirm the exact end date and any notice/auto-renewal window, and gather 12–24 months of usage (and interval data for larger accounts).
- 3–5 months out: establish the utility benchmark and request comparable offers on matched delivery dates.
- 2–3 months out: normalize and compare offers apples-to-apples, and review the contract terms.
- Before the notice deadline: decide and, if switching or renewing, execute — and give any required notice on the existing contract.
Starting late compresses this and often means fewer usable options and greater exposure to a holdover rate.
Auto-renewal and holdover traps
Two clauses cause most renewal losses:
- Automatic renewal — the contract renews for another term unless notice is given within a set window.
- Holdover / post-expiration rate — if the contract simply ends, supply rolls to a variable rate that is frequently much higher than a shopped rate.
Both are covered in more detail in the contract expiration risks guide.
Multi-site portfolios
Portfolios rarely share one end date. Build a renewal calendar so no meter silently rolls over — see multi-location energy procurement.

Timing drives options; no renewal outcome or savings figure can be promised in advance.
Frequently Asked Questions
QWhen should an Illinois business start an energy renewal?
For most commercial accounts, begin 3 to 6 months before the current supply contract ends. That window allows time to gather usage, request comparable offers, and review terms — and, critically, to act before any auto-renewal or notice deadline in the existing contract takes effect.
QWhat is a holdover or post-expiration rate?
If a supply contract ends and nothing is done, many agreements roll to a variable holdover rate or automatically renew. Holdover rates are often much higher than a shopped rate. Knowing the exact end date and notice window is the single most important step to avoid this.
QCan a contract renew automatically without my action?
Yes. Many commercial supply contracts contain automatic renewal provisions that trigger unless the customer gives notice within a defined window before expiration. Reading that clause early — not at expiration — is what preserves the ability to shop.
