Commercial battery storage

Turn peak demand charges into revenue opportunities.

Commercial battery storage that eliminates demand charges, provides backup power and generates VPP income. Zero CapEx with Total Care.

The problem

Peak demand charges are destroying your budget.

Peak demand charges can represent 30 to 50% of commercial energy bills, hitting businesses with $10,000 to $30,000+ monthly penalties for using electricity when everyone else does. Meanwhile, grid instability threatens operations with increasing blackout risks.

The solution

Smart battery storage that pays for itself.

Commercial-grade BESS engineered to cut peak charges, provide backup cover and generate VPP revenue — under one managed contract. One system. Three ways it pays.

Peak shaving

Discharge through high-tariff windows to cut the peak kVA charges that drive 30–50% of your bill.

Backup power

Sub-100 ms transfer keeps critical loads running through outages, protecting trade and stock.

VPP revenue

Spare capacity earns from grid-services markets when it isn't shaving peaks or backing up loads.

20–40%
Reduction in peak demand

Our control platform forecasts demand spikes and discharges the battery through high-tariff windows, cutting the peak kVA charges that drive 30–50% of your bill — automatically, every billing period.

How it works

Smart dispatch, every second of the day.

Zool Energy's control platform monitors, predicts and dispatches your battery automatically — no team needed, no guesswork.

Step 1
AI pattern learning

Learn your load

AI algorithms learn your consumption patterns across days, weeks and seasons to understand when you typically spike.

Step 2
30-min forecast window

Forecast the peak

Predict demand spikes up to 30 minutes ahead, combining historical data with real-time meter readings.

Step 3
100 ms dispatch time

Shave the peak

Automatically discharge to shave the spike before it hits your demand meter. Sub-100 ms response.

Step 4
Off-peak recharge

Recharge smart

Recharge during off-peak windows using cheap grid electricity or solar generation — whichever costs less.

VPP integration

Your battery earns while it protects.

+$45K
Typical annual VPP income per site

When your battery isn't shaving peaks or backing up critical loads, Zool Energy dispatches spare capacity into grid-services markets. The revenue flows back to you.

FCAS market participation

Your battery provides frequency control ancillary services when there's surplus capacity, earning from one of Australia's most lucrative grid-services markets.

ROI analysis

The numbers speak for themselves.

A typical commercial BESS installation delivers three stacked revenue and savings streams — before Zool Energy's zero-upfront model even enters the equation.

Case study — three-site shopping centre portfolio

Challenge: $25,000/month peak demand charges across three sites, plus 8 blackout events in the prior year costing an estimated $150,000 in lost trade and spoilage.

Solution: Zool Energy deployed a 2 MWh battery portfolio under Total Care, with intelligent load management coordinating across all three sites.
