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 commercial sites this is the biggest single saving a battery makes.
Watch what a battery does to the evening spike. It banks your solar through the middle of the day, then carries the site through the evening peak so the grid never sees it.
Illustrative day. Your real curves come from your interval data, modelled in Ampaura Designer.
Your bill is really two bills. 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's what it charges you for.
Peak shaving is a daily routine. The system fills the battery before the risk window opens, then discharges the moment demand climbs toward the threshold.
Load, solar and tariff forecast for the day ahead, rebuilt every day.
The battery is filled from the day's solar and held ready before the risk window opens.
The moment demand climbs toward the threshold, the battery discharges and holds the peak down.
AI Mode measures what happened and re-plans, so the threshold keeps tightening.
The NSW Peak Demand Reduction Scheme pays certificates for exactly what this page describes, and our systems are certified for it. If your site is in NSW the numbers improve again.
