ProjectRed uses its own power system called electrotine power https://ftb.gamepedia.com/Electrotine_Power

The system is designed after real world electricity. Sadly, the documentation is lacking (as in: non-existant, not even their wiki has entries for the electrotine blocks) and the amount of blocks that even use or produce said power can be counted on one hand:

• Solar Panel
• Electrotine Generator
• Auto Crafting Bench
• Charging Bench
• Battery Box

The issue is, project red is written in scala and makes heavy use of its traits system, which is not-compatible to java (as in, you cannot use scala traits in java without some additional work like wrapping the traits in classes).

I'm not really familiar with scala and therefore I wont be implementing this anytime soon. In addition, due to the scala dependency, i'd rather have this in its own (addon-)mod since the tile entity code will most likely be written in scala as well.
