Template:Short description Template:Use dmy dates Template:Infobox power transmission line The Isle of Man to England Interconnector is a submarine power cable connecting the transmission system of the Manx Utilities Authority to that of Great Britain. With an undersea section of approximately Template:Convert,[1] it is the second-longest AC undersea cable in the world.[2]Template:Efn

Route

It was laid in 1999 between Bispham, Blackpool, England, and Douglas Head on the Isle of Man, commencing commercial operations in November 2000. It is capable of continuous operation of 40Template:NbspMW at 90Template:NbspkV (although other sources say 65Template:NbspMW at 132Template:NbspkV AC[3][4])

Structure

The cable was manufactured in two parts: one section at the former BICC works in Erith and the other at Pirelli Cables in Southampton. It ended the Isle of Man's dependence on local diesel-powered generation.[2] Power supplies to the island were increased in 2003 by an 85Template:NbspMW combined cycle gas turbine power station at Pulrose, in the capital, Douglas.[5]

The electricity cable is bundled with a fibre-optic cable which is used for telecommunications. The cable is owned by e-llan Communications, which is part of Manx Utilities. The electricity cable is used for importing and exporting electricity between the Isle of Man and the GB National Grid.[4][6]

The cable is mostly buried at around Template:Convert depth but is on the seabed surface at six locations with protective cable mattresses.[3]

Capacity

On the 20th anniversary in 2020 of its commissioning a total of 1.5Template:NbspTWh of power has been exported to the UK grid which contributed £47Template:Nbspmillion to the revenue of the Isle of Man.[7]

The amount of electricity sold to the UK since 2014Template:Ndash15 and the revenue gained each year was as follows:[8]

Electricity to the UK, GWh 93 87 105 95 131 192 168
Revenue from sales to UK £1.8M £3.2M £4.6M £3.2M £3.4M £4.3M £3.8M
