Frequently Asked Questions
How many Coal Generators can one Water Extractor support?
One Water Extractor produces 120 m³/min of Water at 100%. Since each Coal Generator consumes 45 m³/min, the optimal ratio is 3 Water Extractors (360 m³/min) feeding exactly 8 Coal Generators (360 m³/min total) producing 600 MW.
What is the base power output of Fuel Generators in Update 1.0 & 1.2?
Fuel Generators produce 250 MW at 100% clock speed (rebalanced from Early Access 150 MW), consuming 20 m³/min of standard Fuel or 7.5 m³/min of Turbofuel.
How much water does a Nuclear Power Plant consume?
A standard Nuclear Power Plant producing 2,500 MW consumes 240 m³/min of water, requiring exactly 2 Water Extractors at 100% clock speed (or 1 Water Extractor overclocked to 200%).
