Since you have state dan interest in the subject of power generation ,there are more options presenting themselves.
This link is about the powerplant in question .

I would like to stress that none of the 3 component powerplants are operational in game time actual .
The "Fossil fuel Units" -presumably coal /petro burning steam turbines have been shut down due to lack of spareparts and repairs. There has also been a fire in the machinery causing a lot of damage.Specific parts and experst are required to get this going again .
the mobile gas units are shut down due to a lack of spare parts and technical expertise.This relates to the gas pumping station by the gas wells , the reduction gears at the units themselves and the control unit for the ga sturbines .Specific parts and said expertise is needed to get these going .They seem to have sustained a little damage from neglect ,but repairs will probably have them running again .
The nuclear plant was put in SAFSTOR mode in 1985 with a projected viability of 30 years .Due to the events of 2005 and onwards ,nothing has been done since the twilight fell. ( 34 years ago) .This means that the plant is on hiatus .The 250ft smokestack has been removed .Also there is no unspent fuel at the facility (uranium rods) .Lastly ,the running of the plant requires technical expertise that you do not as of yet have .(I will allow for you to make a roll on winging it though
)
There you have it !A lot of possible power sources in one place ,but how to get the stuf fto make them work -and who to trust with the job ? Whoever controls this will more than likely run the town in the years to come....Imagine the price you get extort from a whole town if you had the last spare parts to their only hope for electricity -in the world....
