Sizing a battery, live: the three decisions behind a C&I storage business case – Suno Charge

A live walkthrough of how a commercial and industrial storage business case gets built, run on real consumption data from an anonymized site.

Starting from a load curve and a tariff structure, the session works through the three decisions that determine whether a deployment happens: whether the site works at all, what size the battery should be, and which value streams the business case can legitimately count. Cases that do not clear are shown alongside cases that do.

Particular attention goes to where most models stop. Peak shaving and arbitrage are straightforward to model. Demand response, aFRR and SRAD are not, and that is where a meaningful share of the revenue sits. The session covers how those streams are approached and what it costs a business case to leave them out.

Closing on the operational side: the engine producing the simulation is the same one that dispatches the battery once installed, so the case that justifies the investment and the control layer that delivers it are the same code.

Intended for EPCs, installers and technical teams building storage capability.
