Question to the Department for Transport:

To ask the Secretary of State for Transport, how much renewable energy generation is delivered from the Network Rail land estate; and which individual facilities generate the largest supplies of electricity.

Network Rail does not currently hold data on the total amount of renewable energy generation delivered from its land estate as solar installations have been delivered at a regional and route level to date. Network Rail is working to gather this data. The individual facility on Network Rail’s land estate that generates the largest supply of electricity is Blackfriars Bridge, the world’s largest solar bridge, which generates at 850kWp (around 900,000kWh per year) and covers 6,000m².
