Battery storage ROI
Savings from peak shaving, cash flow and payback.
Model calculation – not tax or investment advice
This calculator provides a non-binding, simplified model calculation based on your inputs and documented assumptions. The results do not constitute tax, legal or investment advice and do not replace an individual review by your tax adviser. No warranty is given for accuracy or returns.
In three steps you estimate the savings potential and economics of your battery storage.
- 01
Size the storage
Enter the capacity, power, and planned investment amount of your storage system.
- 02
Capture grid costs
Provide peak-load reduction, demand charge, and expected arbitrage revenue.
- 03
Read the ROI
The calculator shows annual savings, cashflow, and a rough payback period.
The calculator estimates the economic benefit of a battery storage from peak shaving and arbitrage.
With peak shaving, the storage reduces your load peaks. Since grid fees are often billed via a demand charge per kW, the reduced peak load produces a direct annual saving on the grid fee.
In addition, the storage can exploit price differences by shifting charge and discharge times (arbitrage). From these building blocks and the investment amount, the calculator derives cashflow and a rough payback period.
The actual values depend on your load profile, the grid operator, the operating strategy, and market prices and may differ from the model.
The calculation is based on simplified assumptions and is not a guarantee of specific savings.
We size your storage to be grid-friendly and economical – turnkey and throughout operation.
Grid-friendly design
We size capacity and power to match your load profile so that peak shaving and revenue work together.
