There are two generators here, one is running one is not. They are on the south wall, raised up off the ground on a platform. You have to climb the stairs to get to them.
Running around the South and West walls is a pipe with 3 valves. It's unclear if they are on or off, or even important. They all appear rusted. There are a number of other pipes around the walls
There is a wooden cupboard on the north wall, and next to that are more pipes, and a lever.
The ceiling in here is cracked and damaged. There even appears to be blood on both the roof and floor. Something happened in here.
There is a switchboard next to the steps.
For anything else (if anything else) you will need to search the room carefully.
