The short answer
Re-shop your fixed-rate contract 60-90 days before expiry. Inside 30 days is too late (EDI 814 takes 30-45 days to complete). Beyond 120 days is too early (suppliers will not price longer-than-current-quarter forward). Suppliers compete hardest in the 60-90 day window. Set two calendar reminders the day you sign any contract: -90 days and -60 days.
Renewing a fixed-rate energy contract is the single most important habit for households and businesses on competitive supply. The 60-90 day window before contract expiry is when suppliers compete hardest for renewals; outside that window, customers either pay an early-termination fee, miss the supplier-competition pricing, or fall into the silent rollover trap. This guide walks the calendar discipline.
Why 60-90 days is the sweet spot
Inside 30 days of expiry: too late. Suppliers cannot price aggressively because they cannot hedge fast enough. The EDI 814 handshake takes 30-45 days; if you sign at day 15, you risk a gap month on variable default. The how-to-cancel-energy-supplier-contract guide walks the timing.
60-90 days out: ideal. Suppliers can hedge favorably for the new term, pricing competition is at peak, and the EDI handshake completes well before old contract expiry.
More than 120 days out: too early. Suppliers will not price longer-than-current-quarter forward yet. Stamp the contract end-date in your calendar with a -90 day reminder and a -60 day reminder. Re-shop in that window every cycle.
When to lock vs when to wait
Signal 1: wholesale futures curve shape. If the next-12-month NYMEX curve is in contango (later months priced higher), lock now. If in backwardation (later months cheaper), wait briefly.
Signal 2: capacity-auction clearing prices. PJM 2026 cleared at decade-high; that flows into supply offers in 2027. If recent capacity clears are high, lock now. The capacity-market-pjm-ercot-explained guide walks the mechanic.
Signal 3: weather forecast for the next 30-60 days. Forecasted polar vortex or heat dome can spike near-month wholesale prices. Lock just before the forecasted weather spike if you can.

The renewal-watch automation
Most US households and small commercial accounts miss the renewal window not because they cannot decide, but because they forget. The supplier auto-rolls them onto a variable default; the next bill is 20-40% higher; they discover the trap at month 13. The avoiding-the-renewal-trap guide walks the rollover mechanic.
Seenra automates this. Every contract end-date stamps into our re-shop calendar. The system runs comparison shopping in the 60-90 day window and surfaces the recommendation.
If you are not on Seenra, set two manual calendar reminders the day you sign any new contract: one at -90 days, one at -60 days.
Recap
Bottom line
The 60 to 90-day pre-expiry window is the sweet spot for renewing fixed-rate energy contracts. Inside 30 days is too late for clean EDI handshake; beyond 120 days suppliers will not price aggressively. Two calendar reminders set the day you sign any contract — one at -90 days and one at -60 days — protect against the silent rollover trap that catches most US households on competitive supply.
The avoiding-the-renewal-trap guide walks the rollover mechanic; the when-to-lock-in-electricity-rate guide covers the broader timing decision for new contracts. For households who want fully automated re-shop hygiene, Seenra runs the calendar discipline automatically; for households managing manually, two phone calendar reminders are enough.
