What is the estimated energy requirement for a full-length electronic advertising board beside a London Underground escalator over a full year?

A run of digital ribbon screens, which feature alongside escalators at some stations, has an estimated energy requirement of approximately 40,296kw over the course of a year. Please note this figure is based on an average of 25 screens on each side of the escalator – but this number can vary depending on the length of the escalator at each station.

The new digital advertising assets installed on our network are on average more energy efficient than the digital assets which they are replacing. Although they will never completely replace poster sites they have a number of important environmental benefits, such as removing the need for printing, creating less vehicle journeys for installation, and creating no paper, card or vinyl waste.
