• AQUIND Interconnector will increase competition across energy markets, improve security of supply and help foster greater renewable power integration


AQUIND Limited (‘AQUIND’) is developing proposals to build a new High Voltage Direct Current (‘HVDC’) marine and underground electric power transmission link between the south of England and Normandy in France – AQUIND Interconnector.

AQUIND Interconnector will have capacity to transmit approximately 5% of Great Britain’s total electricity consumption per annum – enough to keep the lights on in up to 5 million British households.

It will make a significant contribution to improving Great Britain’s security of electricity supply and achieving greater affordability by improving competition, making Great Britain’s energy market more efficient and enabling greater energy flexibility.

Further, AQUIND Interconnector will help to integrate a greater proportion of non-fossil fuel energy sources and intermittent renewables generation into Great Britain’s
energy mix.

In July 2018 the Secretary of State for Business, Energy & Industrial Strategy directed that AQUIND Interconnector should be treated as a Nationally Significant Infrastructure Project (‘NSIP’). This means that the construction and operation of AQUIND Interconnector can only be consented by a Development Consent Order (‘DCO’) made by the Secretary of State under the Planning Act 2008.

Clarification regarding Portsmouth News Article (03/04/2020)

It has come to our attention that an article recently published in the Portsmouth News (Friday 3rd April edition) stated that: “A new converter station for the AQUIND Interconnector scheme will now be created outside the South Downs National Park (SDNP) despite previous plans to use the substation at Lovedean.”

Neither the existing National Grid substation at Lovedean, nor the proposed Converter Station associated with AQUIND Interconnector are located within the South Downs National Park, as suggested by the article.

The proposed Converter Station associated with AQUIND Interconnector is proposed to be located to the west of the existing National Grid substation at Lovedean, in accordance with the information submitted within AQUIND’s Development Consent Order (DCO) application. Lovedean substation was identified as the preferred connection location for AQUIND Interconnector following an assessment by National Grid, who have an obligation to maintain the GB electricity grid.

Further information regarding the approach to identifying the Converter Station location is provided on the FAQ page of this website and in the Alternatives Report within the DCO Application Documents. Plans illustrating the location of the proposed Converter Station can be found in the Application Documents, including the Converter Station Parameter Plans.

Dec 2019: AQUIND Interconnector Development Consent Order application accepted for examination

Following two rounds of consultation undertaken between January – February 2018 and February – April 2019, AQUIND submitted its DCO application for AQUIND Interconnector to the Planning Inspectorate (PINS) on 14th November 2019. The DCO application was subsequently accepted for examination by PINS on 12th December 2019.

All application documents are available to view on the Application Documents page, together with further information regarding how to make relevant representations in relation to the DCO application.
