Assumptions for demand l.jpg
Assumptions for demand

  • All of the historic Pick-Ups are Pre Betta, 10% has been added to the forecasts in to take that into account.

  • We expect a drop in demand of approximately 1000 – 1500 MW from 60 minutes before the Kick-Off.

  • We expect a demand drop of approximately 1000 – 1200 MW after the start of the second half.

  • If the weather is bright and sunny, because it is a Saturday there may be a ‘pub effect’ leading to a greater drop in demand during the match and slightly lower pickups.


Tv coverage l.jpg
TV coverage

  • Because electricity demand is predicted to rapidly increase around the England games, there is considerable media interest in National Grid’s role in managing this.

  • At Wokingham, there is pre-recorded filming this week for Sky, GMTV and BBC.

  • We are expecting this to be broadcast at breakfast time on Friday morning to coincide with the start of the World Cup along with all the other TV coverage.

  • Various press releases are being issued.

  • Profiles of key forecasting and control staff will be on our website.
