How much power does each Satisfactory generator make?

A Coal Generator makes 75 MW, a Fuel Generator 150 MW, a Nuclear Power Plant 2500 MW, and a Biomass Burner 30 MW, all at 100% clock.

How much water does a Coal Generator use?

A Coal Generator uses 45 m³ of water per minute and burns 15 coal per minute. Fuel Generators use no water; Nuclear Power Plants use 240 m³ per minute.

Satisfactory Power Guide: Generators, Fuel & Water

Every Satisfactory generator at a glance — power output, fuel per minute, and water per minute, straight from the official game data. Use it to pick a power source and size your grid.

Generator	Power	Primary fuel	Fuel rate	Water
Biomass Burner	30 MW	Leaves	120.00 /min	—
Coal-Powered Generator	75 MW	Coal	15.00 /min	45 m³/min
Fuel-Powered Generator	250 MW	Fuel	20.00 m³/min	—
Nuclear Power Plant	2500 MW	Uranium Fuel Rod	0.20 /min	240 m³/min

Which power source, when?

Biomass Burner — earliest power, hand-fed; fine before coal, retire it quickly.
Coal Generator — your first real power. Simple: coal + water, no byproducts. Build in rows sharing a water line.
Fuel Generator — far more power per building once you have oil. No water needed; Turbofuel pushes output even higher.
Nuclear Power Plant — 2500 MW each, but needs 240 m³ water/min and produces radioactive waste you must store or reprocess.

Fuel rates are derived from each generator's power and its fuel's energy value (power ÷ energy × 60), and water from the game's water-to-power ratio. Plan exact generator counts with the fuel calculator, total your factory's draw with the power calculator, and see how overclocking changes the bill.
