Adds 2 tiers Mining Drills, Solar Panel, and Accumulators that are costly but powerful and also lets you upgrade beginning machines to the late game machines.
In the recent version I discovered the steam engine with low priority. I replaced my engines with one of them, now my accumulators (both standard and hyper) will not discharge anymore despite drawing 60+MW of one at night.
Thanks for reporting this, Looks like how the game works, they batteries will not work with low priority engines since they conflict with providing and storing energy. I would suggest not using them or a nuclear and steam setup without accumulators.
