TFL does pay for electricity, but it pays for it as part of the Crown Commercial Service which aggregates procurement for many large public services in the UK. [1] TFL used to have its own generating stations, which helped keep costs manageable and also meant the trains kept running during power cuts. That ended around 2000. Now it has at least four separate connections to the National Grid, and is supposed to be moving to 100% renewables within the next decade.
