Reading maximum demand lines without guessing

Maximum demand is often the line that surprises finance teams. Usage may look stable while the demand charge jumps because a short peak — sometimes measured over a half-hour window — resets the figure that flows into the tariff calculation for that cycle.

What to gather before you argue

Commissioning logs, weekend maintenance windows, and temporary equipment hire sheets matter more than annual averages. If chillers, crushers, or test loads ran outside normal production hours, the bill may be arithmetically correct even when the cost feels wrong.

How we use the records

During an energy usage billing audit we align interval extracts (when available) with the demand value printed on the statement. The goal is not to invent a lower number; it is to show whether the printed peak matches something that happened on site. That distinction decides whether you ask for a correction or change how future peaks are scheduled.

If the spike coincides with a new meter or feed, start with meter reconciliation before a full audit.
