Ofgem has launched an investigation into National Grid Electricity Transmission plc and SP (Scottish Power) Transmission plc for the delivery and operation of the Western high-voltage direct current (HVDC) subsea cable.
The Western HVDC is a £1.3 billion subsea cable that transports electricity between Scotland, Wales and England. The project was undertaken by a joint venture between National Grid Electricity Transmission and Scottish Power Transmission.
The investigation will review the performance of National Grid Electricity Transmission and Scottish Power Transmission in delivering the cable. It will consider whether its late delivery means they breached special licence condition 6I, which specifies the expected delivery date of the Western HVDC subsea cable. Additionally the investigation will consider compliance with standard licence condition D (provision of transmission services) and section 9(2) of the Electricity Act 1989 (provision of economical, efficient and co-ordinated services).
The investigation will also examine potential breaches relating to the operation of the cable.
The opening of this investigation does not imply that we have made any findings about non-compliance by National Grid Electricity Transmission or Scottish Power Transmission.
- More information on the investigation has been published on our website.
