National Grid Electricity Transmission (NGET), owner of the national electricity transmission system in England and Wales, is expanding its network of modular power-flow control technology in the United Kingdom.
Earlier this year, the company installed the world’s first large-scale use of the technology on its U.K. network. The national electricity-transmission system consists of 4,500 miles of overhead line, more than 900 miles of underground cable and more than 300 substations in England and Wales.
According to NGET, with the increasing volume of renewable generation seeking to connect to the network, there is a pressing need for even more capacity in the area in 2022. Modular power-flow control technology removes bottlenecks and unlocks unused capacity on the existing network.
NGET has already installed 48 SmartValves across five circuits at three of its substations in the North of England, creating 1.5 gigawatts of extra capacity — enough to power 1 mill
