Satisfactory offers five types of generators, each responsible for generating energy: the biomass burner, coal generator, fuel generator, geothermal generator, and nuclear power plant. Most generators can be overclocked using energy modules obtained from energy slugs. Biomass burners, accessible at level 0 after studying the HUB 6 upgrade, use organic matter as fuel and generate 30 MW of electricity. The coal generator, accessed at level 3 after researching coal energy, uses coal and water to generate 75 MW. The fuel generator, unlocked at level 6, uses liquid fuels and generates 150 MW. The geothermal generator uses geysers’ heat, doesn’t use additional fuel, and generates 200 MW. Lastly, the nuclear power plant, accessible at level 7, uses nuclear fuel rods and water to generate a whopping 2500 MW. Each generator has specific requirements for creation, which you will fulfill as you progress in the game.
