Storage expansion forecasting

Storage Capacity Expansion Forecast — Plan Future Battery Requirements

Forecast when existing storage may no longer meet growing energy requirements and quantify the capacity gap that future expansion could need to cover.

Why storage expansion planning needs a timeline

A storage system that is adequate today can become undersized as required energy grows or usable capacity declines. A timeline makes that transition visible.

Demand growth

Each year the required energy is adjusted by the selected growth rate.

Capacity degradation

Existing storage capacity declines under the entered annual degradation model.

Expansion event

An expansion can be added at a selected year so the forecast shows whether the additional capacity closes the future gap.

Limitations

Actual storage planning can include power capacity, duration, temperature, reserve requirements, dispatch strategy and battery warranty conditions.

Frequently asked questions

Can demand growth be negative?

Yes, if you intentionally model declining demand.

Can expansion happen in year zero?

Yes. That models an immediate addition to the existing capacity.
