Not at home right now, but I have tons of MFSU and Redstone Energy Cells to store all of my energy. Once the Ultimate pack is released with RP2, I'll have tons of battery boxes.
Later, I plan on building one of the greg tech storage blocks that store billions of EU, and put it in the very back of my power grid. That way, the MFSU grid keeps supplied and outputting massive amounts of EU while the greg tech storage block will supply at 128 eu/t I believe is its max output.
You just answered your own mysteryI'd have no idea what to actually 'do' with one billion EUs. Other than matter fabricate it all or something else stupid like 50 quarries at once.
What if you have more than it can eat?My mass fab eat the leftover power
Make a few more fabs!What if you have more than it can eat?
