For a stable Satisfactory coal power build, start with one clean module: 4 generators, one normal coal node and enough water. This upgrade changes the save. You stop hand-feeding Biomass Burners and gain a factory that can run while you build.
Key points
- Coal Power unlocks Coal-Powered Generators, Water Extractors, Mk.1 Pipelines and coal scanning.
- One Coal-Powered Generator uses 15 coal/min and 45 m3 water/min at 100% clock speed.
- A Mk.1 Pipeline carries 300 m3/min, so larger coal plants need distributed or separated water lines.
- Satisfactory launched on Steam on September 10, 2024 and supports online co-op.
The usual failure is not coal alone. It is poor water flow, a rushed startup or a grid connection made too early. This guide keeps one goal: a readable coal plant that stays reliable and can double later. For more jeu.video coverage, browse feature articles, gaming news and the latest posts.

Key Takeaways
- Unlock Coal Power in Tier 3 after the first Space Elevator phase.
- One Coal-Powered Generator uses 15 coal/min and 45 m3 water/min at 100% clock speed.
- A normal coal node with a Miner Mk.1 supports 4 generators at full speed.
- Mk.1 Pipelines carry 300 m3/min, so larger blocks need distributed water.
- Build near water early. Coal belts are easier to extend than pipe networks.
Best Satisfactory coal power starter build
The safest starter block is 4 Coal-Powered Generators. It needs 60 coal/min and 180 m3 water/min. A normal node with a Miner Mk.1 covers the coal. Two Water Extractors give a comfortable launch margin.
Place the 4 generators in one line. Bring coal along the back. Bring water along the front. Leave a service lane. If one generator stops, you should quickly see whether the issue is coal, water or wiring.
- Place a Miner Mk.1 on a normal coal node if available.
- Feed coal into a clean splitter line.
- Connect 2 Water Extractors to one main pipe.
- Feed each generator with a short pipe junction.
- Keep Power Poles on the module edge.

Unlock Coal Power without starving the factory
Coal Power is a Tier 3 milestone. The official Satisfactory wiki lists Coal-Powered Generators, Water Extractors, Mk.1 Pipelines and coal scanning as unlocks.
Stabilize your starter factory before leaving for a coal node. Reinforced Iron Plates and Rotors are common blockers. If those lines are slow, fix them first.
- Automate Iron Plates, Iron Rods, Screws, Wire, Cable, Rotors and Reinforced Iron Plates.
- Add temporary storage for slow parts.
- Complete Coal Power at the HUB.
- Scan for coal.
- Choose a node close to a large water source.
- Bring Concrete, Iron Plates, Cable, Rotors, Copper Sheets and backup biomass.

Satisfactory coal power water ratios
One Coal-Powered Generator uses 15 coal/min and 45 m3 water/min. The official Coal-Powered Generator page confirms these values. That means 4 generators need 60 coal/min and 180 m3 water/min.
A Mk.1 Pipeline carries 300 m3/min. Do not treat one pipe as an unlimited backbone. For 8 generators, plan for 120 coal/min and 360 m3 water/min. Newer players usually get cleaner results with two separate 4-generator modules.
| Block | Generators | Coal/min | Water/min | Recommended plan |
|---|---|---|---|---|
| Starter | 4 | 60 | 180 | Normal node, 2 extractors, 1 pipe |
| Comfort | 8 | 120 | 360 | Pure node, 3 extractors, distributed water |
| Clean expansion | 2 x 4 | 120 | 360 | Two separate modules |

Best site for a coal power plant
If you are unsure, build near water. Belts are easy to extend. Pipes need more room and become confusing when terrain climbs. A lake or coast keeps startup problems low.
Save space for expansion. A good starter plant should accept 4 more generators without a major rebuild. Tight terrain becomes painful once steel production starts.
| Coal source | Coal/min | Safe generators | Gross power | Best use |
|---|---|---|---|---|
| Impure node + Miner Mk.1 | 30 | 2 | 150 MW | Emergency or outpost |
| Normal node + Miner Mk.1 | 60 | 4 | 300 MW | First simple plant |
| Pure node + Miner Mk.1 | 120 | 8 | 600 MW | Durable pre-steel block |

Start the plant without tripping the grid
Do not connect an empty coal plant to your main grid. The Miner and Water Extractors need power before the generators run. If your main factory is near capacity, startup load can crash it.
Use a small isolated grid first. Start the Miner and extractors with Biomass Burners. Let coal and water reach each generator. Then connect the plant to the main grid.
- Wire the Miner, extractors and generators on a separate grid.
- Add temporary Biomass Burners.
- Let coal fill the generators.
- Wait until water appears at each input.
- Check the power graph.
- Connect the plant to the main base.

Common Satisfactory coal power mistakes
The first mistake is trusting gross power. Miners, Water Extractors, pumps and support machines also draw electricity. Keep spare capacity before adding another production chain.
The second mistake is random expansion. Add full modules instead. Build 4 generators, then 4 more. This makes failures much easier to read.
The third mistake is hiding critical parts. Keep coal belts visible, pipe junctions reachable and poles out of walkways. When output drops, you need a fast diagnosis.

Progression after coal power
Once coal power is stable, spend the new margin carefully. Target Basic Steel Production first. Steel Beams and Steel Pipes open heavier logistics and stronger factory layouts.
Use one rule for each new line: source, main belt, buffer, clear output. Satisfactory rewards factories that can expand. A longer readable line beats a compact knot.
- Priority 1: improve Reinforced Iron Plates, Rotors and Cable.
- Priority 2: unlock and automate steel.
- Priority 3: build foundations and service paths.
- Priority 4: add a second coal module before power gets tight.

Frequently Asked Questions
How many coal generators should I build first?Build 4 generators first. A normal coal node with a Miner Mk.1 supplies the required 60 coal/min.
Check water. The pipe may lack flow, climb too high without a pump, or feed too many generators.
Build near water early. Coal belts are simpler to extend than beginner pipe networks.
You need 120 coal/min and 360 m3 water/min. Use a pure node with Miner Mk.1 and 3 Water Extractors.
Connect it only after the generators already have coal, water and stable output on an isolated startup grid.
Target Basic Steel Production. Stable coal power gives enough energy margin for Foundries and steel parts.
Yes. The official Steam page lists Online Co-op and Cross-Platform Multiplayer for Satisfactory.
Use the official wiki pages for Coal-Powered Generator, Water and the Steam page.
