The most expensive line on many commercial energy bills is not the result of a bad negotiation. It is the result of no negotiation at all. When a fixed-rate energy contract reaches its end date and the business does nothing, an auto-renewal or evergreen clause can quietly roll the account onto a new term—or worse, onto an open-ended holdover rate that runs far above the market. No signature, no alert, no new negotiation. Just a higher bill that keeps arriving until someone notices.
This is one of the most common and avoidable ways commercial buyers overpay.
The discipline is simple once you know what to look for.
How Auto-Renewal and Evergreen Clauses Work
Buried in most fixed-term energy contracts is language governing what happens at expiry. There are three common patterns, and the difference between them is the difference between a fair renewal and an expensive trap:
- Evergreen / holdover: At expiry, the contract continues month to month at a variable "holdover" rate set by the supplier. This rate is frequently the most expensive product the supplier offers, precisely because it targets customers who did not act.
All three share one feature: they reward inaction with a worse rate. The supplier's incentive is straightforward—a customer who forgets to shop is a customer who pays more. The clause is legal and disclosed, but it depends on you not reading it.
Reviewing Holdover and Month-to-Month Terms
Holdover and month-to-month rates carry a premium because they price in maximum uncertainty and zero commitment. When you sign a fixed term, the supplier can hedge your load on the forward market and offer a sharper rate. On a month-to-month holdover, there is no commitment to hedge against, so the supplier prices defensively—and adds margin because it can.
The damage compounds with time. A business that rolls onto holdover in a high-price season—summer in ERCOT territory, or a winter gas spike—can absorb months of premium pricing before anyone reconciles the bill. Our deeper look at the real cost of month-to-month utility rates walks through how quickly this adds up. With capacity costs feeding into rates after the record PJM capacity auction, the gap between a managed renewal and a passive rollover is wider than it has been in years.
How to Find the Clause in Your Own Contract
You can identify your exposure in a few minutes. Pull your current supply agreement and locate these items:
- The contract end date. The single most important date to know. Put it on a calendar today.
- The renewal provision. Search the document for "renew," "evergreen," "holdover," "continue," or "month-to-month." This tells you what happens if you do nothing.
- The notice window. Look for how many days before expiry you must notify the supplier to prevent renewal—commonly 30, 60, or 90 days. Missing this window is how most businesses get trapped.
- An email to the wrong address may not count.
If you cannot find or interpret these provisions, that itself is a signal to get a second set of eyes on the contract before your end date approaches.
A Step-by-Step Plan to Never Roll Over Unfavorably
Avoiding the trap is a matter of timing and a simple system:
- Build a renewal calendar. For every account, record the end date and the notice deadline. Set reminders 120 and 90 days out—before the notice window closes.
- Fixed-rate offers move with the forward market, so early benchmarking gives you time to lock a favorable moment rather than scrambling at the deadline. Pull competitive quotes via a letter of authority .
- Decide: renew, re-source, or restructure. Compare a fresh competitive rate against your incumbent's renewal offer. If you are locked and want to act sooner, see blend-and-extend and early termination.
- If you are already on a month-to-month holdover rate, treat it as an emergency—every billing cycle at that rate is avoidable overpayment.
This is exactly the kind of ongoing renewal management a good broker provides so you do not have to track it manually. For a broader pre-renewal walkthrough, use our renegotiation checklist. Consumer protections around automatic renewals also exist at the state level; your state public utility commission and resources from the U.S. Department of Energy can point you to them.
Red Flags When Signing a New Contract
Negotiate these terms up front:
- Shorten or remove the holdover rate. Cap any post-expiry rate at your contract rate rather than an open-ended variable.
- Widen the notice window in your favor.
- Get renewal terms in writing. Ask the broker or supplier to state exactly what happens at expiry—and confirm your broker will proactively re-bid rather than let you roll.
Why did my business energy rate suddenly jump?
The most common cause is a contract that expired and rolled onto a holdover, month-to-month, or utility default rate. These post-expiry rates carry a premium because there is no fixed commitment for the supplier to hedge against. Check your end date and renewal clause first.
How do I stop my energy contract from auto-renewing?
Then benchmark the market and either re-source or negotiate a new term before your end date.
How far ahead should I shop for a renewal?
Fixed-rate offers move daily with the forward market, so early benchmarking lets you lock a favorable moment instead of accepting whatever rate is available on your deadline.
Is a holdover rate the same as the utility default rate?
Not exactly. A holdover rate is set by your retail supplier when a contract lapses into month-to-month status. The utility default (or "price to compare") is the rate you revert to if you have no supplier contract at all. Both are typically higher than a competitively sourced fixed rate.
Can a broker manage renewals so I don't get trapped?
Yes. Ongoing renewal management—tracking end dates, sending timely notice, and re-bidding the market before expiry—is a core service of a good broker. Confirm in writing that your broker will proactively re-bid rather than let your account auto-renew.
Conclusion
The auto-renewal trap costs businesses money for one reason: it rewards doing nothing with a worse rate. Evergreen and holdover clauses, month-to-month premiums, and utility default fallbacks all quietly punish the buyer who missed a date. Negotiate the renewal terms out of your next contract entirely, and the trap disappears.
