We are currently the single biggest consumer of electricity in London and one of the top 10 electricity consumers in the UK. We expect our use of electricity to increase as we expand and improve our services to meet London's predicted growth.
As part of our strategy to reduce the impact of transport operations on the environment, we have developed a proposal to install up to six new gas engines in Greenwich Power Station's Old Turbine Hall.
This will provide a steady source of cheap, reliable, low carbon power for the Tube network.
We are also developing plans to use surplus heat from the Power Station to supply hot water and heating for nearby schools and homes. This will reduce utility bills for residents and improve local air quality by eliminating the need for gas fired domestic boilers.
Emissions to air, dispersion and noise emission modelling has been completed and the materials submitted to the Environment Agency as part of our permit application. A consultation will be held.
We expect that physical works for the first set of engines will start in early 2018 and that the engines will be running in 2020. Installation of the remaining engines is expected to be staggered over the next 20 years.
Our plan for Greenwich Power Station is part of a wider strategy to reduce the impact of transport operations on the environment and improve air quality. We estimate that when the project is complete it will save around 34,000 tonnes of CO2 a year.
