When I was a young sim mech, at Coltishall, we used approx 10 % of the station power. If there was an "exercise minimise" going on, we would get a phone call from the guard room telling us to turn of the simulator.
Which usually meant an early stack! On the airfield and weapon models alone, there where something like 250 400w lamps, so it was quite expensive to run! The models themselves where nearly 60ft long by 30 wide. Even today the sims I work on account for 8% of station power, mainly because of the motion pumps!
