BESS Sizing Tutorial

Step 1 — Define Peak Load

Insert the maximum demand of the facility (kW). This represents the baseline load before battery operation.

Step 2 — Define Target Peak

Set the desired peak after shaving. The difference between peak and target defines required battery power.

Step 3 — Define Duration

Duration represents how long the battery must sustain peak shaving.

Step 4 — Battery Parameters

Step 5 — Results Interpretation

Engineering Note

This tool provides preliminary sizing only. Final system design must consider protection, thermal constraints, manufacturer data, and site-specific conditions.
