Peak Demand Management
The Most Expensive 15 Minutes on Your Bill
For many businesses, the biggest cost on the electricity bill isn't total consumption. It's peak demand charges. These are based on the highest power draw recorded during a billing period, even if that spike only lasts 15 to 30 minutes.
Think about a cafe at 8am: the espresso machine, the oven, the aircon, and the dishwasher all running at once. Or a medical centre when the imaging equipment kicks in alongside the HVAC. That single spike sets your demand charge for the entire month. A battery system eliminates that spike by discharging stored energy the moment your grid draw exceeds a set threshold.
How It Works
Peak Shaving, Explained Simply
Battery charges
During low demand periods or from your solar system, the battery charges up and stores energy ready for when it's needed.
Demand spikes
When your building's power draw starts climbing towards the peak threshold, the system detects it in real time.
Battery responds
The battery automatically discharges to supplement grid power, keeping your total grid draw below the limit.
Bill drops
Your recorded peak demand is lower, your demand charges drop, and the savings repeat every billing cycle.
It Depends on Your Business
Not Every Business Benefits the Same Way
A battery doesn't make sense for everyone, and we'll tell you that upfront. How much a battery saves you depends entirely on your demand profile, which is different for every business.
A restaurant that runs at a steady load for 6–8 hours probably doesn't have massive demand spikes. A battery will help, but maybe not dramatically. A workshop that fires up heavy equipment for short bursts? That startup current is setting your demand charge through the roof, and a battery can make a real difference.
We only know this by looking at your interval data: the actual 15-minute load recordings from your meter. That's where we start, and that's what determines whether a battery is worth it for your specific situation.
Advantages
Beyond Peak Shaving
Demand Charge Reduction
The primary financial benefit. Even a small reduction in your peak demand can take hundreds off your monthly bill when demand charges make up a large portion of what you pay.
Solar Self-Consumption
Store excess solar generation during the day and use it during peak tariff periods or after hours, instead of exporting at low feed-in rates.
Energy Arbitrage
Charge from the grid during cheap off-peak periods and discharge during expensive peak windows. The tariff difference is your saving.
Backup Power
Maintain operations during grid outages for your critical loads, including EFTPOS, refrigeration, servers, and lighting. Whatever can't go down stays on.
Future Proofing
Grid costs rise and tariff structures change. Battery flexibility becomes more valuable over time, not less.
Fully Automated
The system monitors your load in real time and responds automatically. No manual intervention, no staff time, no complexity for your team.
Assessment
How We Determine if a Battery Makes Sense
We don't sell batteries to businesses that won't benefit from them. Here's what we look at before recommending a system:
Interval Data Analysis
Your meter records power consumption in 15-minute intervals. We analyse this data to identify your peak demand events, when they occur, how long they last, and whether a battery can meaningfully reduce them.
Tariff Structure
Not all commercial tariffs have significant demand charges. We review your rate structure to determine where the real savings are: demand charges, time-of-use rates, or both.
Business Type & Load Profile
A cafe with steady daytime load is very different from a workshop with short heavy-draw bursts. We model your specific usage patterns to size the battery correctly and project realistic savings.
For SME-scale projects, this assessment is included as part of our standard consultation. For larger commercial and industrial projects, a paid feasibility study is required, involving electrical engineering analysis, complex modelling, and detailed financial projections.
Better Together
Paired With Commercial Solar
Battery storage delivers the best return when paired with an appropriately sized solar system. Solar provides free daytime energy to charge the battery, and the battery extends those savings into evening and peak tariff periods.
Together, they cover the full cycle: generate during the day, store the excess, shave your demand peaks, and reduce the amount you buy from the grid after hours.
