Forward-Start Contracts: Pros and Cons

A forward-start contract is a supply agreement you sign today for a delivery period that begins later — commonly the day after your current contract expires. The distinguishing feature is that the pricing decision and the delivery period are separated in time. You commit to a price now; energy starts flowing under the new terms months down the road.

For an Illinois business planning around a renewal, this can be a useful tool or an avoidable mistake, depending on why you are doing it and what you give up. This guide explains the mechanism and the trade-offs.

How a Forward-Start Contract Works

In a standard renewal, you shop and sign close to the date your new supply period begins. A forward-start contract moves the signing earlier. You might, for example, be a year into a current agreement and choose to lock the supply price now for the period that starts when that agreement ends.

The price reflects the wholesale forward market for the future delivery window, not today's spot conditions. Suppliers build forward quotes from where the market is pricing that future period, plus their costs and margin. So a forward-start price is not "today's rate extended" — it is the market's current view of the future period.

Everything else about the contract still applies. The delivery utility — ComEd in northern Illinois, Ameren Illinois in central and southern Illinois, or your gas utility — continues to deliver and maintain service regardless of when the supply contract starts. The forward-start decision affects only the supply portion for the future window.

When Locking a Future Period Can Help

• You have a view that the future period will be more expensive. If forward prices for your delivery window look attractive relative to what you expect later, locking removes the risk of waiting into a rising market. You are converting an uncertain future price into a known one.
• Budget certainty matters more than upside. Organizations that need a firm number for planning may value locking a future period early so the figure is settled well before the period begins.
• You want to decouple the decision from a bad calendar moment. If your contract ends during a season when you are stretched thin, or historically when prices are seasonally elevated, signing earlier lets you make the pricing decision on your own timeline rather than under end-of-term pressure.
• You are consolidating multiple accounts or sites onto a common date. Forward-start terms can help align staggered end dates so future renewals happen together.

When It Can Hurt

• Prices can fall after you lock. The core trade-off is that a fixed forward price does not benefit from a later decline. If the market softens for your delivery window after you sign, you are committed to the higher price.
• You lose optionality. Locking early removes your ability to react to new information — a change in your load, a shift in the market, or a better structure that emerges before the period starts.
• Exit is not free. A signed forward contract is a real obligation. If your plans change, termination typically follows a market-difference or liquidated-damages formula, so unwinding it can carry cost.
• Your load forecast may be wrong. The further ahead you commit, the more your business can change before delivery — an expansion, a closure, added electric equipment. If your actual usage diverges from what the contract assumed, the bandwidth or swing terms come into play for the future period. See bandwidth and swing clauses.
• Longer lead times price more uncertainty. Suppliers pricing a period far in the future are pricing more unknowns, which is generally reflected in the quote.

Questions to Work Through First

Before locking a future period, be able to answer these:

1. What is my current end date, and does the forward start line up with it cleanly? A gap or overlap between contracts creates its own problems.
2. Why do I believe now is a better time to price this period than later? If the honest answer is only "to get it done," weigh that against the flexibility you give up.
3. How confident is my load forecast for the future window? Known changes to your operations should shape both the volume and the swing terms.
4. What does the exit cost look like if my plans change? Read the termination clause before signing, not when you need it.
5. Are the non-price terms as good as the price? A sharp forward rate paired with broad pass-throughs, a tight band, or an aggressive auto-renewal may not be the win it appears to be. Compare full terms, not just the number, using comparing offers apples to apples.

Fitting It Into Your Renewal Plan

Forward-start contracts are most useful when they are part of a deliberate renewal process rather than a reaction to an expiring term. Working backward from your end date gives you room to evaluate whether locking a future period makes sense for your situation, or whether waiting closer to the start date serves you better. Our contract renewal timeline lays out that schedule, and the clause-by-clause contract guide covers the terms that travel with any supply contract, forward-dated or not.

There is no universally right answer. Locking a future period is a way to manage timing risk, and like any risk decision it trades one exposure for another — certainty in exchange for flexibility. The right choice depends on your view of the future period, your tolerance for being wrong, and how firm your load forecast is.
