What Happens When Your Illinois Energy Contract Expires and You Do Nothing
Find out what happens when your Illinois energy contract expires and you don't take action. Learn about automatic rollover risks, default rates, and how to protect your business.
What happens to your Illinois business's energy costs when your contract expires and you do nothing? For many business owners, this scenario plays out in real time—quietly and expensively—every year. The answer isn't immediately obvious from your bill, which is part of the problem. The change from a negotiated contract to default utility service can appear seamless on the surface while costing your business hundreds or thousands of dollars more each month.
The Illinois energy market is deregulated, which means your business can choose its electricity or natural gas supplier. But that choice isn't permanent. When your contract expires, you need to make a new decision—or the system makes one for you, and not in your favor.
This guide explains exactly what happens when your Illinois energy contract expires without action, why the consequences can be financially significant, what the most common automatic rollover pitfalls look like, and—most importantly—how to take control of your commercial energy rate before it's too late.
The Hidden Dangers of Letting Your Illinois Energy Contract Expire Without a Plan
When a commercial energy contract expires in Illinois, one of three things typically happens: you've already signed a new contract (good), your current supplier automatically rolls you into a new term (potentially bad), or you fall back to default utility service (often expensive). The third scenario—default service—is the most common outcome for businesses that aren't actively managing their energy contracts.
Default service in Illinois means your electricity supply is provided by ComEd or Ameren at their regulated default rate, called the Price to Compare (PTC). The PTC is not a negotiated rate. It's a market-reflective rate that can change monthly, providing no budget certainty and typically running above what competitive fixed-rate contracts would provide in stable market conditions.
The Financial Impact of Falling to Default Service
Consider a mid-size Illinois retailer whose contract expired in February without a replacement in place. Their supply rate under the expired contract was $0.055/kWh. The PTC for their ComEd territory that month was $0.072/kWh—a difference of $0.017/kWh. At 50,000 kWh per month, that's $850 in additional monthly costs—$10,200 annually—simply from the contract lapsing.
Important Warning
The transition from a contracted rate to default utility service happens automatically and silently. You won't receive a notification that says 'your rate just increased by 30%.' Your bill will simply reflect the new (higher) rate, often without clear explanation unless you read the fine print carefully.
Beyond the rate, losing your contracted supply arrangement means losing the price certainty, supplier relationship, and terms you negotiated. Getting back to a competitive contracted rate requires starting the procurement process from scratch—and if you're now on month-to-month default service, you have no leverage and no timeline pressure on the supplier side.
How Illinois Utility Default Rates Could Be Silently Draining Your Business Budget
Default utility rates are designed as a safety net—a backstop that ensures businesses always have electricity supply even when they don't have a retail supplier contract. They're not designed to be competitive. The Illinois Commerce Commission oversees the utilities' default service procurement, but the resulting rates are generally higher than what an active, well-advised commercial buyer could negotiate.
Why Default Rates Are Higher
Utilities procure default service supply through periodic auctions rather than through continuous competitive procurement. These auctions happen on a fixed schedule and don't allow for opportunistic purchasing when market prices dip. Retail suppliers, by contrast, can hedge energy supply across multiple market windows, often achieving lower effective costs that they pass through to contracted customers.
Seasonal Volatility Risk
Default rates that change monthly expose your business to seasonal electricity price volatility. Summer heat waves and winter cold snaps drive wholesale electricity prices higher, and those increases flow directly into the default rate. Businesses on competitive fixed-rate contracts are insulated from these spikes during their contract term.
Default vs. Contracted Rate — Illustrative Monthly Impact
| Month | Default Rate (PTC) | Contracted Rate | Usage (kWh) | Excess Cost |
|---|---|---|---|---|
| January | $0.075 | $0.057 | 45,000 | $810 |
| February | $0.072 | $0.057 | 43,000 | $645 |
| July | $0.082 | $0.057 | 55,000 | $1,375 |
| August | $0.085 | $0.057 | 58,000 | $1,624 |
| Annual Total | — | — | 600,000 | $11,400 |
This illustrative example demonstrates how a single year of operating on default service—relative to a competitive contracted rate—can cost a mid-size commercial customer over $11,000. For larger businesses with higher usage, the gap widens proportionally.
What Illinois Business Owners Must Know About Automatic Rollover Energy Contracts
Not all expired contracts default to utility service. Many retail energy supplier contracts include automatic renewal (rollover) provisions that extend the contract—sometimes at a higher rate—if you don't provide written notice of your intent to switch within the required window.
How Automatic Renewal Clauses Work
A typical automatic renewal clause might read: 'If customer does not provide written notice of intent to terminate at least 60 days prior to the contract end date, this agreement shall automatically renew for an additional 12-month term at the then-prevailing market rate.' The key phrase—'then-prevailing market rate'—means the supplier sets the rate at whatever it determines is appropriate at the time of rollover, with no competitive process.
Illinois law provides some consumer protections for automatic renewal clauses in certain contracts, but commercial energy contracts may not receive the same level of protection as residential ones. Review your contract's automatic renewal provisions and mark the notice deadline in your calendar the day you sign.
How to Identify If You're in an Automatic Rollover
- Request your contract's full terms from your current supplier if you can't locate them
- Look for language about 'automatic renewal,' 'evergreen provisions,' or 'rollover terms'
- Compare your current rate to the rate specified in your original contract—an unexplained change may indicate rollover
- Contact your utility to confirm which supplier is currently registered to your account and under what arrangement
- Review your most recent bill for any indication of contract term or expiration date
How to Take Control of Your Illinois Commercial Energy Rate Before It's Too Late
Whether your contract is expiring soon, has already expired, or you're caught in an automatic rollover, the path forward is the same: take control by engaging in a competitive procurement process now. The sooner you act, the sooner the savings begin.
- 1**Determine your current status.** Find your current contract and expiration date. If you can't locate it, contact your supplier or call your utility to find out which supplier is currently registered to your account.
- 2**Check for active automatic renewal provisions.** If your contract has already renewed automatically, determine whether early termination is possible and at what cost.
- 3**Gather your usage data.** Collect 12 months of usage data from your utility bills. This is the foundation for any competitive RFP.
- 4**Contact Illinois Energy Advisors.** Our team can assess your current situation, determine your options, and begin gathering competitive quotes within 24 hours.
- 5**Execute a new competitive contract.** Once you have quotes in hand, select the best rate and terms, authorize enrollment, and lock in your new rate.
Even if your contract has already lapsed onto default service, you can switch back to a competitive retail supplier at any time. There's no minimum time you must remain on default service. The sooner you act, the sooner you stop paying the default rate premium. Use our Bill Analyzer to get a free assessment of your current energy costs.
Frequently Asked Questions
What happens to my Illinois energy rate when my contract expires?
When your Illinois energy contract expires, you'll typically be moved to either your utility's default service rate (ComEd PTC or Ameren PTC) or, if your contract has an automatic renewal clause, you may be rolled into a new term at a rate set by the supplier. Either scenario is generally less favorable than a newly negotiated competitive contract.
How long does it take to get back onto a competitive energy contract after lapsing in Illinois?
The process takes approximately 30–60 days from the time you select a new supplier to when the new rate appears on your bill. Gathering quotes can happen within 24–48 hours through an energy broker. The switching process itself takes the remainder of the time.
Is there a penalty for letting my Illinois energy contract expire?
Generally no, if the contract simply expires without renewal. The consequence is moving to default utility service or an automatic rollover rate, both of which are typically more expensive than a newly negotiated rate. Review your contract for any specific provisions.
How can I tell if my Illinois energy contract has an automatic renewal clause?
Review your contract document for language about 'automatic renewal,' 'evergreen,' 'rollover,' or similar terms. Look for a required notice period for cancellation—this is a strong indicator of an automatic renewal clause.
Can I switch energy suppliers immediately if my Illinois contract has expired?
Yes. If your contract has expired (not in an automatic rollover with a new term), you can switch to a new retail supplier at any time. The process takes 30–60 days, but you can initiate it immediately.
Conclusion
Letting your Illinois energy contract expire without a plan is one of the most common—and most avoidable—energy management mistakes for Illinois businesses. The consequences are real: higher rates, less budget certainty, and potential exposure to automatic rollover provisions that are designed to favor the supplier, not your business.
The fix is simple: treat your energy contract like any other significant business agreement. Know your expiration date, start the renewal process 6–9 months in advance, engage in competitive procurement, and don't sign anything without reading and understanding the renewal provisions.
