Manx Cable Company Limited

Manx Cable Company installed the Isle of Man’s subsea power interconnector to Great Britain, a 104 km alternating-current (AC) cable system linking the Isle of Man and North West England. Manx Utilities stated that the cable was installed in 2000 by the Manx Cable Company (a subsidiary of Manx Utilities) in partnership with National Grid, supporting the Island’s security of supply and enabling power trading between the Isle of Man and Great Britain. The installation scope included laying the subsea cable between Port Skillion (Isle of Man) and Bispham (Lancashire, England). The work involved burial of the cable beneath the seabed using a specialist burial plough, consistent with standard interconnector installation practice to provide mechanical protection and reduce external interference risk. Manx Utilities also noted that a fibre optic cable was installed alongside the power cable to provide command-and-control functionality, with additional telecoms capacity. The interconnector was described as a major engineering achievement at the time, reportedly the longest AC subsea cable in the world at delivery, and it was commissioned around 25 years before the 2026 publication date. This role relates to the construction-phase subsea cable installation works for the Isle of Man–Great Britain interconnector.
