Aquind wins at the European Court of Justice – ACER’s appeal is dismissed – The Judgment of the General Court is confirmed.

AQUIND welcomes the ECJ confirming the judgment of the General Court that the promoters of interconnector projects can request optimal regulatory arrangements that are suitable for each individual project.

The European Union Agency for the Co-operation of Energy Regulators (ACER) appealed against the judgment of the General Court of the European Union of 18 November 2020, Aquind v ACER, annulling the decision of the Board of Appeal of ACER made in 2018, which stated that interconnector promoters could not request exemption until they had attempted to request a Cross-Border Cost Allocation Regime under the TEN-E Regulation.

Their appeal is dismissed (please see details).

A spokesman for Aquind Ltd said:
We welcome the decision of the ECJ. It means the ECJ confirms that the promoters of interconnector projects can request optimal regulatory arrangements that are suitable for each individual project. ACER’s position would have put an unnecessary administrative burden on such projects and delayed the implementation of projects vital for achieving energy transition goals.

By connecting power generation capacity in Britain and France, AQUIND Interconnector will contribute to energy security, improve resilience against supply and price shocks and help reduce the curtailment of renewable power generation and CO2 emissions in both Britain and Europe. This project is one of the key elements of infrastructure to help reach Net Zero sooner and at a lower cost.



Notes to Editors

➢ An Interesting Fact: Demand = Generation +Transfers.
At 10am today Live Electricity Demand (UK) was 41.8GW, UK Generation was 35.4GW, the shortfall of 6.4GW was made up by Interconnector transmission. (National Grid )

➢ AQUIND Interconnector is a bi-directional subsea electrical power transmission link between Lovedean Hampshire UK and Normandy France.

➢ AQUIND Interconnector will have the net capacity of 2 GW sufficient to transmit up to 17 TWh per year, which is equivalent to 5% of Great Britain’s and 3% of France’s total annual electricity consumption.

➢ AQUIND interconnector will help integrate a greater proportion of non-fossil fuel energy sources and intermittent renewables into the GB energy mix, helping meet the UK’s 2050 Net Zero target by reducing CO2 emissions by 22.5-25.7 million tonnes, avoiding the curtailment of 73,000-87,000 GWh of renewable energy and saving 92,000 GWh (e.q.) of fossil fuels in power generation (TYNDP 2020 and 2022).

➢ AQUIND Interconnector will have a critical role in meeting the anticipated increase in the UK’s electricity demand. The Energy White Paper issued by BEIS in December 2020 set the target of 18 GW of interconnection capacity between Great Britain and neighbouring markets by 2030. Interconnectors will help integrate the growing share of renewable power generation and satisfy the demand for electricity stemming from electrification of transport and other sectors of the economy.

➢ AQUIND Interconnector will help reduce the impact of volatile gas and coal prices, which have caused electricity bills to increase in 2022/23. By making energy markets more efficient and competitive, AQUIND Interconnector will create £5.3-£9.6 bn in social economic welfare benefits over the first 25 years of its operation.

➢ AQUIND Interconnector will create construction contract opportunities worth approximately £1.35 bn, with 1,000 (direct and indirect) full-time jobs during the 2-year construction period, and bring additional investment to the local economy.

➢ AQUIND has attracted significant funds to finance pre-construction stage of the project, which is near completion. As soon as the Secretary of State grants the Development Consent AQUIND is ready to complete the tender process and proceed to the initial phase of the construction.

➢ AQUIND is engaging with key infrastructure (equity and debt) investors. Construction costs are estimated to be £1.35 bn. Revenues will come from congestion rent, GB and FR capacity markets, and ancillary services.
