I've yet to find a city with reactor buildings... after 4 attempts, all the while I've been expanding my base, automating this and that, etc. Currently I have a 'power thirst' of around 1000rf/t (Auto tree farm & water maker, auto sieve, various 'workshop' machines, etc). Without the lava gens, it was getting excessively grindy to make and then maintain the generators
Try the directons North/East (700/900 ish meters) North (1700 ish meters and slighly due west mostly north though) and West (800/1200 meters), on the 3 maps i have played/seen so far in on of those 3 locations there is always a generator building. Dunno how town generation works, but it seems in those directions there are always large town and other points of interest that slightly vary in composition. The default save game for me, spread over those 3 towns, has about 9 reactor buildings and a couple of subways and some nether structures. If my assumption is correct you should get lucky in either of those 3 towns regardless of generation.
1000rf/t.... wow... someone needs to turn off their lights!
seriously, how can you be using this much power constantly...
I have 6 furnace generators atm, and they satisfy all my power needs, except the mob farms which power themselves.
I don't get how maintaining generators can get to be a pain really either, no automation?
With full-time automation on most farms and stuff you can get past 1000 rf/t rather easy tbh, specially if you rely on pulverizer's instead of hammer set ups to get your sand/gravel. And if you dont bother to high oven it and just furnace the stuff it stacks up even faster with a good and speedy SFM sieve set up.
Add a laser drill to that, and youll quickly be over 20k rf/t depending on the config for the laser drill.
