Yikes! That's some serious suck.... I know whole towns that use less than that.....
I'm guessing that they use a combination of venue and genny, or would they simply go all genny ?
I really can't think of any place around here with that kind of supply.
I did some re-thinking and their old PAR can rig was probably 1600-2000 amperes. It's gone down since 7 years ago as they used more movers to replace single color fixtures, and more recently going to LEDs and video-based lighting fx. They still do some impressive pyro, too. Their lighting load is about 60% of what it used to be.
Seven years ago at our county's old arena, it was a combination of gennies and venue power. At our new arena downtown, we have 2400 amperes of service split between SR and SL, with another 400 ampere service in a back-house left vom and another 400 from the catwalk. They also have 3 200 amp services and 2 400 amp services for TV production and satellite trucks on the south west side of the venue.
