How to Build a Commercial Energy Procurement Calendar

The most expensive commercial energy outcomes are usually caused by timing, not by a slightly higher rate. Contracts lapse into holdover rates, notice windows close unnoticed, and offers get compared in a rush without clean data. A procurement calendar fixes this by turning renewal from a surprise into a scheduled process. This guide covers how to build one: mapping every meter's deadlines, then placing each preparation step on the calendar so decisions are made from a position of choice. It complements the renewal timeline guide, which explains why the window matters; here the focus is on constructing the calendar itself.

Step 1: Inventory every meter and contract

Start with a complete list of what you buy. For many single-site businesses that is one electricity account and possibly one natural gas account. For multi-site operators it can be dozens of meters across different utilities and suppliers. For each one, record:

• The service address and utility (for electricity, ComEd in northern Illinois or Ameren in central and southern Illinois; for gas, the local delivery utility).
• The account or meter number and rate class.
• The current supplier, if the account is on a competitive supply contract, or whether it sits on the utility's default supply.
• The commodity: electricity, natural gas, or both.

This inventory is the backbone of the calendar. A meter that is not on the list cannot be managed, and in a portfolio the meter that slips is almost always one nobody wrote down.

Step 2: Record two dates for every contract

For each supply contract, find the executed agreement and pull out two dates that matter more than any other:

1. The contract end date — when the current term expires.
2. The notice or auto-renewal window — the period before expiration during which you must give notice to prevent an automatic renewal, and after which options narrow sharply.

These two dates are decided by the contract you already signed, and neither announces itself. The notice deadline almost always comes before the end date, which is why the calendar is built backward from the notice window rather than forward from today. Write both dates down for every meter. Where an account sits on utility default supply with no fixed term, note that too, because it can be shopped at any time and belongs in the planning rhythm.

Step 3: Place the preparation steps on the calendar

With the deadlines mapped, schedule the work that has to happen before each one. A workable rhythm for a typical account, counting backward from the notice deadline:

• About 6 months out — gather data. Collect 12 to 24 months of usage, and for larger accounts request interval data through the utility. Confirm the numbers against the actual bill; see how to read a ComEd commercial electric bill for the electricity side.
• About 4 to 5 months out — benchmark. Establish the utility price-to-compare for the delivery period you will actually shop, so every offer is measured against the same yardstick. Sometimes staying on default supply is the right answer, and the benchmark is how you know.
• About 3 months out — request offers. Ask suppliers for offers on matched delivery dates and matched volume, so the quotes are genuinely comparable.
• About 2 months out — compare and review. Normalize the offers and compare them apples-to-apples, then review the contract terms behind each one — inclusions, pass-throughs, bandwidth, and termination language, not just the headline rate.
• Before the notice deadline — decide and act. Choose, execute if switching or renewing, and give any required written notice on the existing contract. Missing that final notice step can undo all the earlier work.

The exact spacing flexes with the size and complexity of the account, but the sequence is constant: data, benchmark, offers, compare, decide.

Step 4: Coordinate a multi-site portfolio

Portfolios rarely share a single renewal date. Each meter can carry its own contract, term, and notice window, so treating the portfolio as one event guarantees that some meters get handled late. The calendar solves this by listing every meter's deadlines individually and then grouping the work into waves — clusters of meters whose windows fall near each other can be prepared and shopped together, which reduces effort without forcing everything onto one date.

Over time, a portfolio manager can also decide whether to deliberately align future end dates so the account is easier to run, or to stagger them intentionally to avoid concentrating market exposure in a single period. Both are legitimate strategies; the calendar is what makes the choice visible. For the broader portfolio approach, see multi-location energy procurement, and fold the whole effort into the wider commercial energy procurement process.

Step 5: Keep it current

A procurement calendar is a living document, not a one-time build. Each time a contract is signed, add its new end date and notice window immediately, while the terms are fresh. Each time a new site or meter is added to the business, add it to the inventory. Review the whole calendar on a regular cadence — a quarterly pass is common — so upcoming deadlines are always visible several months out rather than discovered at the last minute. If you work with an energy broker, the calendar is also the document that keeps that relationship accountable, because it shows exactly when each account needs attention.

Why the calendar beats reacting

Reacting to renewals as they surface tends to compress every step into a few rushed weeks: usage is pulled hastily, benchmarking is skipped, offers are not truly comparable, and the notice deadline is discovered after it has passed. A calendar reverses that. It surfaces each deadline months ahead, leaves time to assemble clean inputs, and lets the business decide from a position of choice rather than urgency. Nothing about the schedule changes reliability or delivery — the utility still delivers the power and handles outages — but it changes the quality of every supply decision that rides on top.
