Electric power infrastructure in England

London Power Tunnels is a project by National Grid to reinforce the electricity transmission network in London, UK, by constructing more than 60 km of new deep-level tunnels carrying high-voltage cables.

The South London Electric Supply Corporation Limited was a British electricity undertaking. It was established in 1896 to supply electricity to the parish/borough of Lambeth in south London. The Corporation owned and operated a power station at Loughborough Junction. From 1925 it formed an association with three other London companies to centralise electricity generation in the new, high thermal efficiency, power station at Barking. The South London Electric Corporation was abolished in March 1948 upon the nationalisation of the British electricity supply industry.

Aust Severn Powerline Crossing is the longest overhead power line span in the United Kingdom with a length of 1,618 m (5,308 ft).

Fawley Tunnel, or Fawley transmission tunnel, is a 3-metre (9.8 ft) diameter, 2-mile (3.2 km) long tunnel under Southampton Water between Fawley Power Station and Chilling near Warsash. It carries the cables of two 400kV circuits of the National Grid.

Cleve Hill Solar Park (formerly Project Fortress) is a photovoltaic power station under construction on the Graveney marshes between Faversham and Whitstable, Kent in the UK.

The Severn-Wye Cable Tunnel, also known as the Severn Cable Tunnel, carries high-voltage (400 kV) electricity transmission lines beneath the estuaries of the River Severn and River Wye between Newhouse (Mathern), Monmouthshire and Aust, South Gloucestershire.

The River Medway Cable Tunnels are a pair of tunnels carrying high-voltage electricity transmission lines beneath the lower River Medway between the Isle of Grain and Chetney Marshes, Kent.

The Lower Lea Valley Cable Tunnels, known as the PLUG (Power Line Under Ground) Project during construction, are a pair of 6 km cable tunnels running beneath the lower Lea Valley in east London. Constructed at a cost of £130m ahead of the 2012 London Olympic Games, they are owned by National Grid plc and UK Power Networks.

The Thames Cable Tunnel, also known as the Tilbury – Gravesend Cable Tunnel, is a tunnel carrying high-voltage electrical transmission lines beneath the lower River Thames between Tilbury and Gravesend. It remains the furthest tunnel downstream on the Thames.

The Elstree to St. John's Wood Cable Tunnel, known as The London Connection during construction, is a 20 km long, 3m wide tunnel beneath northwest London. Constructed between 2001 and 2005, the tunnel carries high voltage transmission lines from Elstree substation in Hertfordshire to Lodge Road sub station in Westminster at a depth of 20m below street level.
