Peak demand reduction

The most expensive half-hour of your month, dented

Commercial bills price your whole month off your single worst half-hour of demand. A battery sees that peak coming and caps it before it lands. For most C&I sites this is the biggest single line of battery savings.

Peak shaving, in one picture

One day on site, with a battery working

Your highest half hour of the month sets a demand charge you pay all month. Watch what a battery does to it: it banks your own solar through the middle of the day, then powers the site through the evening peak so the grid never sees it.

It charges in the middle of the day, from the site's own solar.

The charge itself

What a demand charge actually is

Your bill has two different meters running. Energy is the electricity you use across the month, priced per kWh. Demand is how hard you pull it at any one moment, priced per kW against your worst half-hour. The network builds its poles and wires for that worst moment, so that is what it charges you for.

Energy (kWh) is what you use. Demand (kW) is how hard you pull it.
Networks charge for the pull, because they build for it.
Cap the peak and the charge follows it down.
How it works

How the battery takes the peak off

Peak shaving is not a switch, it is a daily routine. The system positions the battery before the risk window opens, then discharges the moment demand climbs toward the threshold.

Forecast

Load, solar and tariff forecast for the day ahead, rebuilt every day.

Position

The battery is filled from the day's solar and held ready before the risk window opens.

Shave

The moment demand climbs toward the threshold, the battery discharges and holds the peak down.

Learn

AI Mode measures what happened and re-plans, so the threshold keeps tightening.

In NSW, the peak itself is worth money

The NSW Peak Demand Reduction Scheme pays for exactly what this page describes, and our systems are certified for it. If your site is in NSW, the numbers get better again.
