Awesome! Thank you that was incredible informative and helpful. Energy cubes are available in 1.1.4, and experimentation showed that one was charging when hooked to all turbines, so I've got 3 ultimate energy cubes being powered by the reactor so far. However, it led to a different issue. The ultimate energy cube outputs 480 volts, and of course most of the machines I want to power take 120. So, I built a 240v and a 120v transformer, and put them in line with my output from the energy cube. This worked great, and stepped my voltage down to 120v just as I expected.
The issue came when I decided to move them.....picking them up (with a pickaxe) turned them each into a 60v transformer. So it went from a 240v transformer block placed on the ground, to a 60v transformer object waiting to be sucked into my inventory.
...wut? Given that these things, especially the 240v one, take a good deal of materials (diamonds!) you can imagine my displeasure. I ended up using a basic energy cube, which takes in the 480v just fine and spits 120v back out. But, is this a known bug with transformers in 1.1.4? Or is there some other way you're supposed to pick them up that doesn't cause them to change?
