National Grid Electricity Transmission (NGET) is deploying technology on its electricity transmission network that can expand the capacity of its existing overhead power lines.
It has installed dynamic line rating (DLR) sensors on five circuits between one of the major North-South power system boundaries, working with LineVision, which provides non-contact overhead power line monitoring systems,
The new technology covers circuits between Penwortham (Preston) and Daines (Manchester) and four circuits from Norton (Middlesborough) to Thornton (York), totalling over 275km of overhead conductor.
NGET says the technology could save consumers around £20 million per year, by helping to tackle constraints.
The new installation follows successful use of the technology on a 275kV circuit between Penwortham and Kirkby in Cumbria and the implementation of LineVision technology on National Grid’s networks in New York and Massachusetts.
