How it works
Maintain uninterrupted power as factory demand rises. Each stage in the walkthrough below has a distinct practical objective; complete the current supply or control loop before expanding it.
Practical advice
Inspect current generation, usage and satisfaction. An idle machine can indicate no demand rather than a malfunction, while low satisfaction can make every electric machine appear slow.
Mistakes to avoid
Never assume an unrelated blueprint or another version of Factorio has identical recipes, technology unlocks or machine ratios. Use the checkpoints in this guide to diagnose your own save.
Electricity from steam to nuclear: complete walkthrough
Read the electrical network
Inspect current generation, usage and satisfaction. An idle machine can indicate no demand rather than a malfunction, while low satisfaction can make every electric machine appear slow.
Add solar storage
Pair daytime solar generation with accumulators and appropriate backup. Watch charge levels across a full day/night cycle rather than relying on an instant snapshot.
Plan nuclear as a system
Nuclear requires uranium mining, processing and fuel; reactors generate heat which must reach exchangers, steam turbines and fluid supply. Validate each chain independently.
Build resilience
Separate critical defenses and pumping from nonessential consumers, set backup reserve alarms, and avoid a circular dependency in which electricity is needed to produce its own rescue fuel.
