Run an
Auog or
Ablaze auog as fuel in the
Auog powered generator. When that fuel animal is used up, collect
Tired auog from the spent-fuel slot. It has no ordinary crafting recipe.
1. Prepare the generator and a fuel animal
Unlock Domestication – Stage 1, craft an Auog powered generator, and obtain an additional Auog for fuel. The generator’s construction recipe itself consumes an Auog; that animal becomes part of the building and is not a fuel supply.
For a first animal, open the
Auog page and use its Creature chamber recipe. Recharge recipes require an existing tired animal, so they cannot bootstrap the first one.
2. Consume the animal under power demand
- Place the generator and connect it to an electrical network with a load.
- Insert an Auog or Ablaze auog into its fuel inventory.
- Let the generator consume that fuel while supplying electricity.
- Collect the Tired auog from the separate spent-fuel output.
In the installed prototypes, an ordinary Auog stores 500 MJ and an Ablaze auog stores 800 MJ. Both return the same Tired auog item after being consumed. The waiting time depends on the generator’s actual power output and demand; an idle animal in a chest never becomes tired.
3. Recharge it at a Pyphoon bay
Send the tired animal to a
Pyphoon bay. At the first Domestication stage you can use this food-based recipe:
There is also an early meat-based alternative:
Return the recharged ordinary Auog to the generator. Supply food or meat and moss continuously, and remove animals from the spent-fuel slot so the generator can keep cycling. Later recharge recipes use different inputs and may handle several animals per batch; select the version you have researched on the Auog recipe page.
If you cannot find the tired animal
- The animal disappeared during construction: make a second Auog for fuel.
- The generator is idle: check connections and electricity demand. Other power sources may already be satisfying the network.
- Fuel is present but no tired animal yet: wait until a complete fuel item has been consumed.
- The machine stopped: inspect both the fuel slot and spent-fuel output. Clear the output before assuming the recipe is broken.
- The planner has no crafting recipe: this item is a fuel return. Its item page lists acquisition equipment instead.
Other tired animals can have different compatible equipment. Follow each item’s “How to get” section instead of assuming every species uses the Auog generator.
Sources, versions and checking
Written from the guide’s recipe export and installed Factorio prototype data, checked 11 November 2026. Recipe quantities use the FactorioLab full-suite snapshot retrieved 3 November 2026 (Factorio 2.1.21, pY Alien Life 3.1.8). Fuel behavior and breeding probabilities were checked against installed Factorio 2.1.24 prototypes with pY Alien Life 3.1.8. Research costs use the guide’s separate resolved technology snapshot.
This is a data-checked walkthrough, not a recorded playthrough. Startup settings, other mod versions and different mod combinations can change recipes. Quantities shown with fractions are expected yields. Base recipe seconds do not include machine speed, fuel or electricity. Follow the linked item pages to compare alternatives.
