Power Management in Factorio: A Comprehensive Guide

Factorio is a power hungry game, literally. In this article, we will look into power management through all phases of the game, from your very first boiler and steam engine to the endgame when your PC struggles to keep up. We will discuss how to mix and match power sources effectively and transition between them.

First Electric Power Setup

In the early game, you start with minimal resources, including a few assemblers and your crashed ship. The first power setup involves:

1. Offshore Pump: Pumps water into boilers.
2. Boilers: Convert water into steam using fuel (coal or wood).
3. Steam Engines: Convert steam into electric power.

A simple and effective ratio is one boiler to two steam engines. For instance, each boiler consumes 1.8 megawatts of power, and each piece of coal provides 4 megawatts of power.

Scaling Up Coal Power

As your base expands, you will need more power. A full-scale coal power setup involves:

• 20 Boilers and 40 Steam Engines: This ratio matches the maximum output of one offshore pump, which produces 1200 water per second.
• Fuel Management: Ensure a steady supply of coal or wood. A yellow belt of coal might not suffice at full operation, requiring at least a red belt to meet demand.

Transitioning to Solar Power

Solar power is a crucial mid-game upgrade to reduce pollution and ensure a steady power supply. Key steps include:

• Building Solar Panels: Solar panels produce power during the day, reducing the load on steam engines.
• Using Steam Engines as Backup: During the night, steam engines or accumulators can supply power.

Integrating Solar and Accumulators

For a more sustainable and balanced power system, combine solar panels with accumulators:

• Ratio: 25 solar panels to 21 accumulators ensures power during the day is stored and used during the night.
• Pattern Design: Create a repeatable pattern that includes solar panels and accumulators to maintain an optimal ratio.

Advanced Power Management with Nuclear Power

Nuclear power is the endgame solution for massive power needs:

• Building a Nuclear Power Plant: A small nuclear power plant with four reactors can significantly boost power output.
• Balancing with Solar and Accumulators: Use nuclear power to complement solar and accumulator setups, especially during high power demand periods.

Optimizing for Megabases

In the late game, when building a megabase, performance optimization becomes critical:

• Solar Power Efficiency: Solar panels are computationally efficient as they don’t require extensive calculations like nuclear power.
• Nuclear Power for High Capacity: Use nuclear power to handle high power demands but be mindful of its impact on game performance.

Conclusion

Effective power management in Factorio involves transitioning from basic steam engines to advanced nuclear power plants, with solar power and accumulators providing a balanced and sustainable solution. By understanding the ratios and optimizing your setup, you can ensure your factory runs smoothly through all phases of the game.
