did you just used new shp's for the old power planet ?
(IMO not rewrited rules.ini)
If you did this can happen for many reasons
1) where do you set your shp's ?
the game reads files in
special order
if it reads your shp first, and then the original shp then it will override your files
try to leave them loose in the directory (at least for test)
2) check the names of your files
do they have correct name as in rules.ini?
(for example gapowr.shp and gapowr_a.shp for allied power plant)
check this
