Setup: Deadly virus wiped out 80% of population. We are following a group of 500 survivors who managed to go through the disasters and take care of themselves for 2 years already (Story time is 2 years after disaster).
This group wants to have electricity back. Because fridges, lights in the night and planning to set up some broadcast and try to find out if there are more survivors (for whatever reasons, they did not find any new survivor for past half a year)
The group is located nearby power source of your choice. Only limitation is that this power source has to be existent (and running) by end of year 2016.
The problem: No one in group actually worked in any power plant or anything related to power generation. There are clever people inside the group (know how stuff works and/or handymen).
Also, for whatever reason, the power source of your choice went through emergency shutdown and is not generating any power at the moment.
The tools: Assume you have access to public library. Also assume that there might be some general manuals to be found inside the power plant. Also assume that most of security devices in and around the plant are not working and the group already managed to get to the power plant.
The goal: People in my group calculated that they need at least 10 MW of power to run their broadcasting station. (They might be wrong, but thats not scope of this question. Please consider this as limitation)
The question: What power plant is easiest to boot up from ground and run? And can you actually do it?
P.S.: No zombies are around and the group is not endangered by outside factors (weather and nature), so you have all the time you need. Just do not be stupid as I was last time with nuclear power plant
