Where does London get its electricity?
London uses an enormous amount of electricity every day, but surprisingly little of that power is actually generated inside the city.
In this video, we follow the journey of electricity from power generation across Great Britain to the homes, businesses, trains, and buildings of London. You'll see how wind, natural gas, nuclear, solar, other renewables, and international interconnectors feed Britain's interconnected electricity system — and how that power eventually reaches the capital.
We also look beneath London's streets at the massive underground infrastructure helping keep the city powered, including the London Power Tunnels, Grid Supply Points, local substations, and the distribution networks operated by UK Power Networks and SSEN.
By the end, you'll understand why London isn't really powered by London — and how electricity can travel a surprisingly long distance before reaching an outlet in the city.
