Upgrading Coal Power
This guide follows on from the Coal Power 101 guide, the focus here is about expanding coal power, in particular using overclocking and underclocking.
The message I hope to convey is by planning your coal power builds from the start, you can easily upgrade their power output with minimal effort.
Overclocking Power Generators
Overclocking power generators is a misunderstood concept, however if you're keen to go out and get slugs for the power shards then you can reduce the amount of generators required by 50% for the same amount of power output.
