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 ...
The times that a register is recording is specified with a five digit code Time Pattern Regime (TPR). So for example a supply with SSC 0943 has two registers with TPRs 00404 and 00405. The 00404 TPR register records from 01:00 to 02:30 and 08:00 to 23:30, and the 00405 register records for the rest of the time.
In the 2010 issue of the code that governs the National Grid, the Grid Code, [12] the Supergrid is defined as those parts of the British electricity transmission system that are connected at voltages in excess of 200 kV. The 2.2 GW undersea Western HVDC Link from Scotland to North Wales was built in 2013–2018. [13]
Nemo Link is a 1,000 MegaWatt HVDC submarine power cable between Richborough Energy Park in Kent, the United Kingdom and Zeebrugge, Belgium. [1] The project is a joint venture between British National Grid and Belgian Elia. [1]

The Western HVDC Link is a high-voltage direct current (HVDC) undersea electrical link in the United Kingdom, between Hunterston in Western Scotland and Flintshire Bridge (Connah's Quay) in North Wales, routed to the west of the Isle of Man. [2]
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 ...
