The London Underground, known as The Tube, is the largest user of electricity in London and the largest private user of electricity in the whole of the United Kingdom.

In July this year, the Tube announced that it will be participating in Demand Response programmes that will deliver it cost savings by using its energy more flexibly. One example of this will be by using back-up power capacity during periods of peak demand country wide, which will lower its demand from the National Grid.

Not only will this allow the Tube to manage use to reduce the risk of outages, but it will deliver significant cost-savings for the organisation.

Such a high-profile adoption of Demand Response technologies and an influential endorsement of DR as a good financial move for large organisations that have high energy-use, will help projects like Sim4Blocks reach its objectives in motivating consumers and industry to adopt DR programmes themselves.
