How do I calculate total power usage in Satisfactory?

Add the power draw of every building: base power × count. Overclocked machines draw more (clock^1.321929). This calculator sums it for any mix of buildings, counts, and clock speeds.

How much power does a Constructor use?

A Constructor uses 4 MW at 100% clock, an Assembler 15 MW, a Manufacturer 55 MW, a Smelter 4 MW, a Foundry 16 MW, and a Refinery 30 MW.

Tired of your grid tripping the moment you plug in one more Manufacturer? You need to know your real power draw before you build.

The Satisfactory Power Calculator adds it up for you. List each building, its count, and its clock speed, and it returns the exact megawatts to supply — overclocking included (power scales with clock^1.321929). Size your coal, fuel, or nuclear plant once, with headroom, and never brown out mid-expansion again.

Sizing your power grid

Plan a comfortable margin above your peak draw — machines that idle when storage is full still reserve their rated power, and you want headroom for expansion. Once you know your target megawatts, plan generators with the fuel calculator, and see how overclocking changes a building's draw. To plan the production behind the power, use the production calculator.
