Market outlook
Australia's battery market, in context
Battery storage is becoming a larger part of the electricity system. These observed market figures explain the direction of travel; your project's economics still depend on its own data.

Standards and support
The evidence behind your system
Product documentation, site requirements and the connection pathway are checked for your project before we quote.
Product documentation
Review the system specifications and the standards stated in the product datasheets.
Site and connection
The study scopes installation requirements, protection settings and the network connection pathway.
Local support
Operator training and local support are included. Monitoring and maintenance are scoped by agreement.
Applications
Where battery storage can make a difference
Different sites need different models. Follow the path that matches your operation.
Councils
Assess peak demand and solar use at depots, pools, waste and water facilities.
Mine sites
Model diesel consumption, reserve requirements and generator operating hours.
Remote communities
Assess solar and storage against fuel deliveries and the loads that matter.
Commercial and industrial
Start with your tariff, demand profile and existing solar to find the right fit.
BESS CAPEX and ROI calculator
Model upfront equipment, installation and connection costs, then compare NPV, IRR and payback over 20 years. All figures are indicative scenario estimates in AUD, excluding GST. Presets are illustrative, not current market prices or a supplier quote.
Project parameters
Project investment
Grid-Scale (5-10 MWh). Illustrative starting assumption; replace with your supplier quote. Changing capacity resets this cost.
Use a site-specific connection estimate from your network or installer.
Set a contingency appropriate to your project risk.

Operating parameters
Technical and financial assumptions
Charging cost uses the average of the off-peak and solar charging rates. Discharge value uses the peak rate. FCAS income is a separate assumption, subject to eligibility and dispatch constraints, with no revenue-stacking optimisation.

Disclaimer
This is an illustrative, unlevered scenario model, not a verified financial forecast. Defaults are legacy assumptions and are not live AEMO prices, product specifications or Edisonic pricing. Tax and depreciation inputs are modelling assumptions only. The model excludes finance costs, GST, grants, battery replacement, terminal value and dispatch optimisation. Actual results depend on:
- Market price volatility and regulatory changes
- Site-specific installation costs and grid connection requirements
- Actual battery performance and degradation rates
- Changes in government policies, incentives, or tax rates
- FCAS market participation and availability factors
- Operating and maintenance cost variations
Professional feasibility studies, detailed engineering assessments, and legal/financial advice should be obtained before making any investment decisions. Edisonic Energy does not guarantee the accuracy of these estimates or accept liability for decisions made based on this calculator.

Battery storage questions, answered
What is a battery energy storage system (BESS)?
A BESS stores electricity and releases it when it's worth more: at peak demand, overnight after a solar day, or when a generator would otherwise have to run. Ours use lithium iron phosphate (LFP) cells, liquid cooling and an energy management system with remote monitoring.
What size of site suits a battery?
Our smallest system is a 233 kWh cabinet. It suits sites whose demand peaks well above 100 kW, sites with a large solar system, and sites that run generators for much of the day.
What is the difference between kW and kWh in battery storage?
Kilowatts (kW) measure how much power a battery can deliver at once. Kilowatt-hours (kWh) measure how much energy it stores. Both matter: power determines which demand peaks or loads it can support, while energy capacity determines how long it can support them. We size both from your load profile or fuel records.
How much does a battery cost?
That depends on size, site works and the network connection. We price systems landed, installed and commissioned once the study confirms the size. The go/no-go costs nothing.
Are there incentives for commercial batteries?
In NSW, the Peak Demand Reduction Scheme has included business batteries above 200 kWh (activity BESS5) since September 2026, and the NSW Government says the discounts cut the upfront cost of batteries by around 20 to 40 per cent. Federal and state programs also fund some council and remote community projects. We check eligibility for your site and system in the study.
