Coal Maker II and Boiler (Coal) II along with Exhaust Scrubber II

I started playing with all of the resources put to the max value so I have way too much wood and coal on my island. I need a way to get rid of it but I don't want to just dump the coal or delete the wood. I want to make it into power, but find that the basic Coal Maker, the Boiler (Coal) and the Exhaust Scrubber are sub-par. There should be a mid-game or late-game equivalent to these pieces.
