The National Grid is the high-voltage electric power transmission network supporting the UK'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.
The 275/400 kV grid and substations in England and Wales are owned and operated by National Grid Electricity Transmission. It also operates the grid and substations in Scotland although the systems are owned by ScottishPower and Scottish & Southern Energy. In Northern Ireland grid and substations are owned and operated by Northern Ireland ...
Typically, a grid code will specify the required behavior of a connected generator during system disturbances. These include voltage regulation , power factor limits and reactive power supply, response to a system fault (e.g. short-circuit ), response to frequency changes on the grid, and requirement to " ride through " short interruptions of ...
In May 2019 the GB grid went its first full week without any coal power. [72] And in spring/summer 2020 from 10 April, the UK grid ran for 68 days, without burning any coal. [3] In 2020, coal produced 4.4 TWh of electricity and Britain went 5,202 hours free from coal electricity generation, up from 3,665 hours in 2019 and 1,856 in 2018. [73]

(1) Nominal grid voltage according to regulation is 230/400 V, [42] but in practice, equipment with 220/380 V is more commonly used. (2) Types C and F plugs are officially recognized by SNI 04-3892.1.1-2003. (3) British type G sockets are common in Riau Islands due to their close proximity to Singapore.
