Factorio - Tips

Updated: 2022-08-13

Power

Steam Engine

1 Steam Engine = 900 kW

Optimal ratio:

1 offshore pump : 20 boilers : 40 steam engines.

(1 boiler 60/s to 2 steam engines 30/s.)

Should be built close to water and coal.

Solar Power

  • 1 Solar panel: 60 kW
  • 1 Accumulator = 5 MJ

Optimal ratio:

20 accumulators : 24 solar panel : 1 MW required

e.g. to satisfy 10MW, it needs 200 accumulators and 240 solar panels.

Nuclear Power

Reactors Heat Exchangers Steam Turbines Offshore Pumps Power
1 4 Exchangers 7 Turbines 1 Pumps 40 MW
2 16 Exchangers 27 Turbines 2 Pumps 160 MW
4 48 Exchangers 83 Turbines 5 Pumps 480 MW
6 80 Exchangers 138 Turbines 7 Pumps 800 MW

Fuel

Fuel Fuel Value Acceleration Top Speed
Wood 2 MJ 100%
Coal 4 MJ 100%
Solid Fuel 12 MJ 120% 105%
Rocket Fuel 100 MJ 180% 115%
Nuclear Fuel 1.21 GJ 250% 115%
Uranium Fuel Cell 8 GJ - -

Intermediate

Battery

Sulfuric acid factory:

  • 1s: 1 iron + 5 sulfur + 100 water=> 50 sulfuric acid
  • 4s: 4 iron + 20 sulfur + 400 water => 200 sulfuric acid

Battery factory:

  • 4s: 1 copper + 1 iron + 20 sulfuric acid => 1 battery

One sulfuric acid factory can support 10 battery factories.

Engine unit

2 pipe factories + 1 iron gear wheel factory => 20 engine unit factories.

Commands

  • Check elapsed game time: /time
  • Change speed: /c game.speed=2

Science Packs

Production rates

Blue science is the slowest.

Science Pack Rate
Red 1 per 5s
Green 1 per 6s
Black 1 per 5s (2 per 10s)
Blue 1 per 12s (2 per 24s)
Yellow 1 per 7s (3 per 21s)
Purple 1 per 7s (3 per 21s)

Green Science

1 Yellow belt factory : 2 Yellow inserter factory : 24 Green Science factory

Calculation: in 1 second

  • Gear: 4 iron => 2 gears
  • Yellow belt: 3 iron => 4 belt
  • Green Circuit: 2 iron + 3 copper => 1 green circuit
  • Yellow inserter:
    • 2 green circuit + 2 gears + 2 iron => 2 inserter
    • 10 iron + 3 copper
  • Green Science = 1 / 6 Yellow belt + 1 / 6 Yellow inserter (1 yellow inserter factory can support 12 green science factories)

Black Science

1 Yellow magazine factory : 3 Red magazine factories : 8 Grenade factories : 1 Wall factories : 10 Black science factories

Blue Science

Roughly:

1 Blue Science factory : 1 Red Circuit factory : 1 Engine Unit factory

More precisely:

1 Blue Science factory : 0.75 Red Circuit factory : 0.83 Engine Unit factory : 0.02 Chemical Plant (Sulfur)

Purple Science

42 Purple Science factories : 10 Electric furnace factories : 15 Rail factories : 30 Productivity module factories

Yellow Science

Roughly

1 Yellow Science factory : 3 Low density structure factories : 1 Flying robot frame factory : 1 Blue circuit factory

Circuits and Modules

Green Circuit

Green Circuit is a key ingredient.

Recipe: 1 Iron + 3 Copper => 1 Green circuit

2 green circuit factories : 3 copper cable factories

Red Circuit

Recipe: 4 Copper cables + 2 Green circuits + 2 Plastic bars => 1 Red circuit

1 Chemical plant (Plastic bar) : 1 Green circuit factory : 1 Copper cable factory : 6 Red circuit factories

Blue Circuit

Recipe: 2 Red + 20 Green + 5 Sulfric acid => 1 Blue

Modules

3 kinds of modules have the same recipe:

  • Level 1: 15s + 5 Red + 5 Green => 1 Level 1
  • Level 2: 30s + 5 Red + 5 Blue + 4 Level 1 => 1 Level 2
  • Level 3: 60s + 5 Red + 5 Blue + 5 Level 2 => 1 Level 3

Resources

  • Iron ore: used for Iron plate or Concrete.
  • Copper ore: only used for Copper plate.
  • Coal:
    • used as fuel in early games.
    • non-battle usage: Plastic bars.
    • for battles: Explosives, Grenade, Poison capsule, Slowdown capsule.
  • Stone: Stone alone can build Brick (2:1), Wall (10:1) and Landfill (20:1).
    • 2 Stones => 1 Brick
    • 10 Stones => 5 Bricks => 1 Wall
    • 20 Stones => 1 Landfill
    • 1 Stone + 1 Iron stick + 1 Steel => 2 Rails

Others

Roboports

Multiple roboports will also increase the flying distances.

Time

Day lasts 25000 ticks or 416.66~ in-game seconds

1 second = 60 ticks

Belt

1 full yellow belt with coal and iron / copper should be enough for 12 steel furnace.
