Satisfactory Power Calculator
Keep your grid stable while scaling. Estimate total factory demand, add reserve headroom, and compare generator setups with fuel and water consumption.
Planning workflow
- Set machine counts and a global clock speed.
- Add reserve margin based on your risk tolerance.
- Review generator count and fuel draw for each power tier.
- Choose a preferred setup and confirm logistics feasibility.
Power Calculator
Estimate factory demand in MW, include reserve margin, and pick a generator strategy with fuel consumption numbers.

FAQ
How does machine overclock affect the power calculation?
The calculator scales machine power using a non-linear overclock curve, so raising clock speed increases power draw faster than throughput.
Why should I keep reserve margin in Satisfactory?
A reserve margin gives you room for startup spikes, temporary overdraw, and expansion. Running at 100% load makes trips and outages more likely.
Does this tool recommend one best generator type?
It shows options across biomass, coal, fuel, turbofuel, and nuclear. The best choice depends on your unlock tier, logistics, and maintenance tolerance.
Can I model a mixed generator grid?
Use the total MW target as your baseline, then split capacity manually across rows (for example 70% fuel + 30% nuclear).
