I ask because I'm having issues. I tried the obvious space saving measure of having water/power/sewage on one city and zoning and developing more another city. It worked for quite a while, but now for some reason the city I play more in is lacking power. It says there are 98MW available from the neighboor city, but it's buying 88. On the producer city, I have ~300MW spare, which it recognises, also saying it's selling 88MW.
How should I go about increasing the amount transfered? Is it true that there is a 100MW cap, evenly spread between eatch city in a microregion (The ones connected to each other)? Would just waiting on each of the cities solve this? Is there any sign showing the city was synced? Is there a log somewhere? Will this work properly if playing offline?
I ask that this not be marked duplicate, I read the thread at Can't buy power from neighboring city the top voted answer just gives up while the second guy says it's all evenly spread.
