What Is Energy Arbitrage? A Practical Guide for Commercial and Industrial Facilities

Energy arbitrage means capturing a price difference between two times, places or forms of the same energy. For a manufacturer, cold storage operator or commercial building, that does not require a trading desk. It requires knowing where the gap sits in your own bill.

The four places the price gap hides

Time. Power prices and tariff charges differ by hour and by season. Moving a load, or running a battery, from an expensive interval to a cheap one is the textbook case.

Tariff. Many sites sit on a rate schedule that does not match their load shape. Two schedules can serve the same meter at very different annual cost, and switching often needs no hardware.

Product. A fixed price, an index price and a layered mix of the two are different products with different premiums. The premium on a fixed rate is real even when the invoice never shows it.

Location. Delivered gas cost is a benchmark price plus basis, and basis moves on its own. Where and how you buy matters as much as when.

Where a plant without a trading desk finds the money

For many commercial and industrial sites, the largest gaps are in the tariff and the contract, not in the wholesale market. On many tariffs the demand charge is set by a single 15-minute interval, so the biggest time-based lever is often a peak you can see in your own data, not a price you read on a screen.

How to find your gap

Start with interval data, not a market view. A 15-minute load profile shows which equipment sets your peak, where load sits idle, and which of the four gaps is largest for your site. Our dashboard is built around that picture: your load against your tariff, your contract against the forward curve, and the projects that would close the gap, with the savings estimated from your own data.

None of the four is guaranteed to be large at your site. Some plants have a well-fitted tariff and a sensible contract, and the gap is small. Finding that out cheaply is also a result.
