In 2019, Tarchon submitted a Grid Connection application to National Grid Electricity System Operator (NGESO), now referred to as NESO. As a result of this application, Tarchon was allocated the East Anglia Connection Node (EACN) as the connection point for the project. Consequently, project infrastructure must be sited in close proximity to the EACN grid connection point, requiring a landfall, onshore cable route and onshore converter station within the Tendring district to facilitate the connection.
