In the UK a lot of the cost of distribution and transmission infrastructure is charged based on your consumption during the three highest demand half hour periods in the year (triad charge). This only applies to large users on half hourly billing, standard domestic consumers just get a distribution fee included in their bill.

- Mvandenbergh 7y agoAh, I didn't really explain that well. The three half hour periods are selected based on the system wide demand. You are then charged for your demand during those periods. So you pay a lot for using capacity when the network is strained. Also, for distribution charging (rather than transmission) there is a half hourly congestion charging mechanism. Every HH period gets put into a red, yellow, or green band and you pay more distribution charge during the red and yellow periods.
