NeuConnect is an HVDC submarine power cable under construction between England and Germany. [1] [2] [3] [4]

Project Status

The main construction phase started in 2023.[5] [6]

As of July 2023, operation is expected to start in 2028.[6][5]

Route

The cable will run between a new substation[7] on the Isle of Grain, in Kent in England to the Fedderwarden substation in Wilhelmshaven in the Lower Saxony region of Germany.[2][3] Landfall will be next to Grain Coastal Park, in Kent, and at Hooksiel, near Wilhemshaven in Germany.[7]

At 725km in length, the interconnector will be one of the longest in the world.[8]

Specification

The HVDC link will consist of two main cables, each approximately 720 km (450 miles) long, together with a much thinner fibre optic cable for temperature and acoustic sensing for about 150 km (93 miles) from each landfall. The DC element will operate at 525 kV,[9] with a maximum capacity of 1,400 MW.[7]

Economics

The project is privately financed and will cost £2.4Bn (€2.8Bn). The project will deliver £1.7Bn in consumer benefits to UK consumers over 25 years, and could deliver a net reduction in carbon emissions of over 13MtCO2 in the same time.[8]

History

Neuconnect Britain Ltd. was established in 2018.[8]

NeuConnect received Interim Project Approval from Ofgem in January 2018.[10]

Public consultation events were held in July 2019.[10]

In December 2019, the planning application was submitted to Medway Council.[10]

In December 2019, Invitations to Tender were launched for the procurement of two converter stations and 720 km of HVDC cabling.[10]

In December 2019, the Invitation to Tender (ITT) stage was launched to procure two converter stations and 720 km of HVDC cables.[11]

In January 2020, the Federal Network Agency in Germany (BNetzA) confirmed the NeuConnect interconnector project in its 2019-2030 grid development plan.[10]

In April 2020, Neuconnect completed site survey work on the Isle of Grain.[12]

A €1.2 billion cable contract was awarded in February 2022,[13] [14] and substations contract in April. [15] [14]

In July 2022, the project reached financial close, allowing early construction works to begin later in 2022. [8]

In October 2022, the cable manufacturer Prysmian started production of the 725km cable.[16]

As of December 2022, early construction works had started in Wilhelmshaven and Isle of Grain,[4] and manufacture of the cable had started.[16]
