National Grid (Great Britain)

Electrical Engineering

The National Grid is the high-voltage electric power transmission network supporting Great Britain's electricity market, connecting power stations and major substations, and ensuring that electricity generated anywhere on the grid can be used to satisfy demand elsewhere. The network serves the majority of Great Britain and some of the surrounding islands, but does not cover Northern Ireland, which is part of the Irish single electricity market. It is a wide area synchronous grid operating at 50 hertz and consisting of 400 kV and 275 kV lines, as well as 132 kV lines in Scotland, with undersea interconnectors to the Isle of Man, Northern Ireland, the Shetland Islands, the Republic of Ireland, France, Belgium, the Netherlands, Norway, and Denmark.

FAQs

Why was Britain's National Grid created?

It answered the problem of an inefficient and fragmented electricity supply industry.

In 1925 the British government asked Lord Weir, an industrialist from Glasgow, to solve the problem of Britain's inefficient and fragmented electricity supply industry. Weir consulted Merz, and the result was the Electricity (Supply) Act 1926, which led to the grid.
