Biomass keeps your first machines alive, but it also keeps you chained to a pile of leaves. The coal jump is where Satisfactory finally feels like a factory game.
Why biomass is a trap
A biomass burner only runs while you feed it. You craft leaves into biomass, then into solid biofuel, then shovel it in by hand. The moment you stop, the lights go out. That is fine for the first hour and fatal for a real base.
The milestone that changes everything
Coal power arrives at Tier 3. Once a coal generator has coal and water, it produces power with no input from you. That single change frees your time to build instead of forage.
Build where both resources meet
Coal generators need coal and water at the same machine. Scout for a coal node near a lake or river, then place extractors at or below water level so the pipes do not fight gravity. A far-apart coal-and-water pair means a long, angry pipe run.
Do not tear down to switch
Keep your biomass burners as a backup grid while the coal plant spins up. If the coal line has a bug, the biomass grid keeps critical machines alive. Merge them only once coal is stable.
Coal is the first step where the factory runs while you sleep. Rush it.
Practical notes
Keep the biomass system running until the coal line is proven, because the switchover window is when grids die. Water extractors must sit at or below water level or the pipes fight gravity. A coal node near a lake beats a pure node far from water, since the pipe run is the hard part.
Build generators in pairs so one maintenance stop never browns the grid. Once coal carries the base, tear down the biomass burners and reclaim the space. Watch the power graph through the first full day of coal, since demand always climbs after the transition.
