Electrical Load Shedding Priority Planner — Build a Limited-Power Load Plan
When a generator, battery or other backup source cannot support every load at once, prioritize what should remain on and see how much demand is left for lower-priority equipment.
Set the usable backup budget
Priority list
How the priority planner works
The usable backup budget is the available power minus the reserve allowance. Loads are then considered from highest to lowest priority. Essential loads are selected first, followed by preferred loads, with shed-first loads considered last.
Why reserve matters
Keeping some output uncommitted can prevent the model from treating every available watt as automatically available for optional demand.
What happens when essential loads exceed the budget?
The result flags the conflict instead of pretending that the system has enough capacity. That is one of the most important outcomes of the tool.
Example
A 5,000 W backup source with a 10% reserve creates a 4,500 W planning budget. Essential loads are protected first within the model, and lower-priority loads fill the remaining budget.
Practical limitation
Real load shedding can depend on shutdown order, control systems, equipment protection, process continuity and whether a device can be interrupted without creating another hazard.
Frequently asked questions
Can I use this for a battery system?
Yes, when the available-power figure represents the output you intend to allocate.
Does the calculator create a switching sequence?
No. It creates a priority-based keep-on and shed-first plan.
Can I add duplicate loads?
Yes. Use quantity for repeated identical loads.
