The short answer
Every US state gives you a 3-10 business day cooling-off period after signing an energy supplier contract. To invoke: send written cancellation (email or portal message) to the supplier customer service address before the window expires. No fee, no questions. Save the email + reply for records.
Every state PUC mandates a cooling-off period after you sign an energy supplier contract — a window during which you can cancel without penalty, no questions asked. The window length varies by state (typically 3-10 business days), but the principle is the same: consumer protection against high-pressure sales tactics, fine-print surprises, and signing in haste. This guide walks the cooling-off rules state by state and the cleanest workflow for invoking the cooling-off if you decide a contract is not for you.
Cooling-off windows by state
Pennsylvania: 3 business days. Pennsylvania PUC rules require suppliers to clearly disclose the cooling-off window in every contract. Ohio: 7 calendar days. PUCO rules apply to all electricity supplier contracts.
Texas: 3 federal business days under Texas PUC rules. ERCOT REP contracts must disclose the window prominently in the Electricity Facts Label. New York: 3 business days for ESCO contracts under NY PSC rules.
Illinois: 10 business days — the longest window in the country. ICC rules apply to both ARES and AGS contracts. Other deregulated states (NJ, MD, MA, CT, RI, DE) have 3-7 day windows. Always check the contract for the exact window.
How to invoke the cooling-off cancellation
Cancel in writing. Phone calls do not create a record. Email the supplier customer-service address (printed in the contract) with: your name, account number, contract date, and a clear statement that you are cancelling under the cooling-off period.
Send the email before the window expires. Most state PUCs interpret the deadline as receipt-by-supplier, not sent-by-customer — leave a 1-2 day buffer.
Keep the email + any reply in your records. If the supplier later attempts to charge you the ETF or push billing through, the cooling-off email is your proof of cancellation.
- Write — no phone calls.
- Email or portal message to supplier customer service.
- Include name, account #, contract date, cancellation statement.
- Send before window expires (with 1-2 day buffer).
- Save email + reply for records.
When to invoke cooling-off — and when to wait
Use cooling-off when: you re-read the contract and find a clause you missed (auto-renew at variable, hidden monthly charge, teaser-rate reset); you find a better offer in the same window; the salesperson made a verbal claim that does not match the written contract.
Do not use cooling-off as a default "I changed my mind" reflex. Cancellations leave a record on your account; serial cancellation can result in suppliers declining to enroll you in future.
If the cooling-off window has passed and you want out, you are looking at an ETF — typically $50-$300 residential. The ETF math (the early-termination-fee-explained guide) decides whether to pay or wait.
Recap
Bottom line
Every US state with retail electricity choice mandates a cooling-off period — a 3 to 10-day window after signing during which you can cancel any energy supplier contract without penalty. The protection exists specifically to defend consumers against high-pressure sales, contract surprises, and signing in haste.
The window is most useful for catching problems you missed at signing: hidden auto-renewal clauses, teaser rates that reset higher, customer charges the rep did not mention. Always re-read the contract within 24 to 48 hours of signing, and use the cooling-off cancellation if anything material is off. The early-termination-fee-explained and how-to-cancel-energy-supplier-contract guides cover the post-cooling-off mechanics.
