A friend of mine came across an article about the Tokyo Waterworks Bureau, saying that during a football match that was a major qualifier between Australia and Japan, staff had to monitor the match. During breaks in play, they had to increase water flow due to increased use of the bathroom, and they had to decrease water flow when play was happening.
I also once saw on a documentary that electricity usage spiked in the UK just after the end of a popular soap opera, because people put on a kettle for a cup of tea. Again, staff working for the UK's electricity grid had to monitor when the soap opera ended, and adjust electricity production accordingly.
I'm accepting of the claim that spikes in water usage and electricity usage can occur. But are they major enough, as claimed, to require monitoring by staff?
