Power generators & fuel
Compare Serpulo and Erekir generators, then calculate the fuel and coolant needed to power your buildings. Open a material link to find its producers.
Power & fuel calculator
Steady-state estimate with full required supply and no overdrive. Factory demand excludes the generator's own operating draw, which is subtracted automatically. Add mining, fuel-production and transport power to your demand. Startup, supply interruptions, heat routing and meltdown are not simulated.
