When this matters
- A facility has solar surplus, demand peaks or costly outages.
- A battery size was selected from panel capacity alone.
- Several revenue or savings streams may compete for the same capacity.
Storage business case
BESS feasibility based on load, power and operational value
Separate kW from kWh, model dispatch by interval and test whether the battery creates value through resilience, peak control, self-consumption or another defined service.

- Functional specification for procurement.
A controlled path from question to evidence
Question → evidence → decision → acceptance
Every scope states what is known, what remains open, who owns the dependency and how the result will be verified.

Storage policy is not a sizing calculation
The DOE’s 2026 ESS framework updates the role of storage in the power sector. A commercial buyer still needs a project-specific route and operating study. Separate required kW from usable AC kWh, reserve for outages from energy available for peak shaving, and grid services from behind-the-meter savings. A rule for a large renewable plant is not a universal battery requirement for every rooftop.
