Terms of Use – BESS ROI Calculator

The BESS ROI Calculator is a free online tool designed to provide preliminary estimates of financial returns from Battery Energy Storage Systems. While the calculator uses standard formulas and inputs, the results are for informational purposes only and should not be considered financial, engineering, or investment advice.

  • Accuracy: The outputs are based on user-provided data such as power rating, tariff rate, charging, and discharge times. Accuracy depends on the correctness of the data you enter.

  • Assumptions: The tool assumes average market benchmarks for system efficiency, degradation, and operational factors, which may differ from real-world conditions.

  • Limitations: Actual project ROI may vary due to factors such as site-specific conditions, grid policies, tariffs, subsidies, maintenance costs, and installation expenses.

  • Advisory: We recommend consulting with certified engineers and financial experts before making any investment decisions.

  • Liability: GridSynk does not take responsibility for decisions made solely on the basis of this calculator.
