Following on from their invitation for delivery partners to supply renewable energy for their London Underground network [1], Transport for London (TfL) have awarded EDF Renewables UK to do so.

The Impact
Following the completion of their Longfield Solar Farm in Essex (expected 2026), EDF will supply TfL for the next 15 years with approximately 80 GWh of clean electricity [2] generated from the solar farm. This is approximately 20% of its output straight to TfL [3].
During the 15-year period, TfL expects to reduce their carbon generation by 28,000 tonnes as a result of this deal [3]. This amount of electricity could run the entire Tube network for a year, or power both the DLR and Tram network for 15 years! [2].
Powering London’s Greener Future
Mayor of London Sadiq Khan welcomed the news, saying: “London is already a world leader when it comes to addressing the climate crisis, so it’s only right that we continue blazing this trail when it comes to our transport system. This new agreement will enable us to power our transport network with clean, green, renewable energy and reduce TfL’s carbon emissions as we continue building a greener and better London for everyone.”
