E-LLAN

Overview

E-LLAN is a short intra-European submarine cable connecting the Isle of Man to the United Kingdom. Owned and operated by the Manx Electricity Authority, it serves the Irish Sea corridor between the Isle of Man and the northwest coast of England, providing a direct subsea link between the two territories.

Route and Landings

In the Isle of Man, the cable lands at Douglas, the island's principal town. On the United Kingdom side, the cable comes ashore at Blackpool on the Lancashire coast of northwest England.

Ownership and Operators

E-LLAN is wholly owned by the Manx Electricity Authority, the statutory body responsible for electricity generation, transmission, and supply on the Isle of Man. The authority operates the cable as part of the island's essential connectivity infrastructure.

Status and Timeline

E-LLAN entered service in 2007 and has now been operational for approximately 19 years. It remains in service connecting Douglas and Blackpool across the Irish Sea.

Regional Context

The United Kingdom is among the most extensively served countries in Europe for submarine cable landings, with 42 cables coming ashore at 105 landing points. The Isle of Man, by comparison, is served by 4 submarine cables across 5 landing points, reflecting the island's more focused connectivity requirements. E-LLAN is a short-haul cable by regional standards — the corridor peers landing in the United Kingdom include systems such as 2Africa, Europe India Gateway, and Apollo, which are intercontinental cables of thousands of kilometres in length. E-LLAN operates at a fundamentally different scale, purpose-built for the relatively short crossing of the Irish Sea.

Measured performance over the last 60 days across 77 ping tests shows an average round-trip latency of 20.2 ms, with a best recorded value of 15.4 ms — figures consistent with the cable's short geographic span.

Strategic Role

E-LLAN provides a direct subsea data path between the Isle of Man and mainland Great Britain, linking Douglas to Blackpool across the Irish Sea. As one of four submarine cables serving the Isle of Man, it contributes to the island's overall subsea connectivity, complementing the other systems that land across the island's five cable landing points.
