The grail!

Power computation:

Terms:
Tradition - A contiguous cluster of power generator blocks.  All blocks must be face to face, edge or corner contact does not count.
Bounding box - The smallest imaginary (cuboid) box that would fully encompass the tradition.


For a given tradition of power blocks where the bounding box dimensions are x,y,and z, and where there are n total number of power blocks in the tradition:

power= 2000000*(1/(1+(1.000696)^(-((x+y+z)/3)^(1.7)*(1/3)))-.5)+(25n)

Or as simplified by wolfram:

Power Regen= 2000000 (1/(1.000696^(-0.0514959 (x+y+z)^1.7)+1)-0.5)+25 n

(2000000/(1.000696^(-0.0514959 (x+2)^1.7)+1)-1000000)+25 x
