First decide what the battery is for
A battery can shave a short power peak, hold energy for critical loads, absorb midday solar or do a mix of these jobs. Those are not interchangeable. If the venue starts with a battery size instead of a problem, the design often becomes expensive and confused.
For a broader look at how those jobs compete for the same capacity, read the guide to combining battery uses.
Power and duration tell different stories
A ten-minute spike calls for a different battery than a three-hour resilience target. The first is mostly about how much power the system can deliver quickly; the second is about how long it can keep delivering it. Looking at both dimensions keeps the project grounded in the actual event schedule. The training-campus example shows how the same choice changes when several buildings share the load.
Keep some room in reserve
If the battery has a resilience role, do not let everyday peak management drain it just before the doors open. The control strategy should protect a minimum reserve and change with the venue calendar. That operating logic is explored in event-day battery dispatch.
Test the plan with real event days
Before locking the design, run it against several representative days: a sold-out event, a quiet day, a hot-weather event and a day with weak solar production. A battery that only works in the average case is not ready for a stadium.
Describe the battery job in plain terms: how much power is needed, for how long, and how much reserve must remain for the venue.
