Whilst ancedotes about Olympic fever are two a penny at the moment, do we actually have any evidence about how interested people are? Well these power demand charts, courtesy of the National Grid, perhaps offer one rough and ready way of looking at how engaged the stay at home audience has been at key points.
Firstly, of all the highest TV audience to date – the opening ceremony. The annotations on the charts are from analysts at the National Grid.
The pink line shows electricity demand for the equivalent Friday a year ago, and the blue line the actual demand during the opening ceremony – which drew an average of 22.4m viewers, the highest since 1998, and a peak audience at 9.45pm of 26.9m.
On it you can clearly see the suppression of electricity demand for key parts of the ceremony, and then above trend (demand excess) usage as the evening wore on.
