TfL taps our largest nuclear fusion reactor to power the London Underground

"TfL currently uses about 1.6 terawatt hours (TWh) of electricity each year, making it the largest single electricity consumer in London. Once operational, the solar installations could supply up to 65,000 megawatt hours (MWh) of renewable electricity each year - equivalent to roughly two-thirds of the Victoria line's annual power consumption."

"By connecting directly to dedicated solar sites, TfL will be able to receive locally generated renewable electricity without it passing through the National Grid or distribution operators, reducing pressure on the wider electricity network. The arrangement should also guarantee power at a fixed price, helping to shield TfL from fluctuations in energy markets while improving supply security through local generation."

"SSE Energy Solutions will now work with TfL to identify suitable sites for the solar installations. These are likely to be located close to the transport network so they can connect directly, and could include a mix of ground-mounted solar arrays and rooftop panels."

Transport for London, London's largest electricity consumer using 1.6 terawatt hours annually, is partnering with SSE Energy Solutions to build solar farms that will supply renewable electricity directly to the transport network. The solar installations will generate up to 65,000 megawatt hours yearly, equivalent to roughly two-thirds of the Victoria line's annual consumption. By connecting directly to dedicated solar sites through private wires, TfL bypasses the National Grid, reducing pressure on wider electricity infrastructure and securing fixed-price power. This arrangement protects against energy market fluctuations while improving supply security through local generation. The project represents one of the first private-wire renewable schemes for urban transport networks and supports TfL's commitment to run entirely on renewable electricity by 2030.
