After Gary got this response from ATR,
I think its may be good to look at it closer that can be done on a general thread.
Some people have called this out, and I think on the whole they are calling it right.
The feed substation for the Alton area is the Cheadle 33kv to 11kv primary. Demand headroom 12.54MVA. Fault level headroom 14.37kv and is not a active network management zone substation.
The Weston Power map does not show Secondary substations, so this is the closest I can get for power feeds for Towers.
When they are talking about amount of power used, they are using it in the context of Peak power draw on start up. It is like pushing a car, at first you have really push to start it moving, then it become easier. So your peak in power use is getting the car moving. Its the same with motors and high power control systems.
There are large motors on site, one being the pump motors on the rapids. It is common practice in industry that when you have more than one star/delta starting motors (thats how big motor start) then they are started a intervals that allow the last motor started to get to speed. Lowering the power draw.
The other rides worked fine with the feeds they have. they have removed the flume, a high peak power ride replacing it with a low peak ride. So the power requirement is lower.
The intervals between start up can be seconds or minutes and keep from sending a supply requirement spike that would blackout the local area. Not the Hour they are alluding to.
“In regards to the staggered ride opening times, as our park is expanding, we are having to stagger opening times due to the amount of power used if we were to open the rides all at once - it often causes an electricity black out in the surrounding area. Therefore we try to prioritise rides in close by areas together for our early ride time so that it is the most efficient way for our guests to enjoy the park."
