Explore the history of National Grid, and discover how energy has evolved over the years shifting away from fossil fuels towards a cleaner, greener net zero future.
Discover the history of National Grid and the energy sector from the Industrial Revolution to the modern day. Travel through time from the birth of the gas industry through to our ambition to help build a greener, cleaner energy system.
The gas industry is born. Britain was still at war with Napoleon when the Gas Light and Coke Company (GLCC) started operations under the seal of King George III. By the following year it was supplying coal gas to light the streets of Westminster.
In the early 1800s Manchester’s police force sought to find ways to light the streets they patrolled. At that time the process of producing and distributing gas, known as undertaking, was privately managed. In 1843, Manchester’s Corporation becomes the first ever municipal undertaking.
Lord Weir recommends the creation of a Central Electricity Board (CEB) to link the UK’s most efficient power stations with consumers via a ‘national gridiron'. It was set up the following year to standardise the nation’s electricity supply.
The UK’s National Grid is born. Commercial operation of the national 132kV electric power transmission grid begins in the UK. It is the first integrated national grid in the world.
The existing electricity network can’t meet consumers’ future demand. Work starts on a new 12-year project to create a 275kV supergrid – with new lines capable of carrying 400kV in the future.
Parliament passes the Electricity Act, creating the Central Electricity Generating Board (CEGB). In popular terms, its aim is ‘to keep the lights on’ – something we still do today.
The transmission activities of the Central Electricity Generating Board, covering England and Wales, are transferred to the National Grid Company plc.
Dealings in National Grid shares start on 11 December 1995, following the company’s listing on the London Stock Exchange.
