Offshore Wind Farms

Scottish Power Renewables – East Anglia Three

Development of an offshore windfarm with an approximate capacity of 1400MW off the coast of East Anglia, within the area known as Zone 5, under the Round 3 Offshore Wind Licensing Arrangements. The Secretary of State approved the application for consent on 7th August 2017. In June 2019 BEIS approved a non-material change to increase the overall capacity of the windfarm from 1200MW to 1400MW. 

More information: East Anglia Three Offshore Wind Farm 

Scottish Power Renewables – East Anglia One North 

An offshore wind farm which could consist of up to 67 turbines, generators and associated infrastructure, with an installed capacity of up to 800MW, located 36km from Lowestoft and 42km from Southwold. From landfall the cables will be routed underground to an onshore substation, which will in turn connect into the national electricity grid via a National Grid substation and cable sealing end compounds at Friston, the latter to be owned and operated by National Grid. Examination of the DCO application completed in July 2021.

Scottish Power Renewables – East Anglia Two

An offshore wind farm which could consist of up to 75 turbines, generators and associated infrastructure, with an installed capacity of up to 900MW, located 37km from Lowestoft and 32km from Southwold. From landfall, the cables will be routed underground to an onshore substation which will in turn connect into the national electricity grid via a National Grid substation and cable sealing end compounds at Friston, the latter to be owned and operated by National Grid. Examination of the DCO application completed in July 2021.

Scottish and Southern Electricity/RWE – North Falls Offshore Wind Farm

An offshore electricity generating station approximately 24.5km from its nearest point at the Port of Lowestoft. It is estimated to have an installed capacity in excess of 100MW and will principally comprise offshore wind turbines together with associated infrastructure (onshore and offshore) including a connection to the electricity transmission network. A DCO application is expected to be submitted in 2023.

Solar Farm Nationally significant infrastructure project (NSIP)

Sunnica Ltd – Sunnica Energy Farm

The installation of solar photovoltaic generating panels and electrical battery storage technology on Sunnica East and Sunnica West, and associated infrastructure for connection to the national grid, including an extension to the Burwell National Grid Substation. The scheme would allow for the delivery of over 50 megawatts of renewable energy over a greenfield site of 2800 acres either side of the Suffolk/ Cambridgeshire border.

Commercial solar farms (under the NSIP threshold of 50MW)

A number of applications for commercial scale solar farms which fall just below the threshold of an NSIP and therefore are considered through the usual planning application process with local authorities as the the decision making body. The following applications have either been formally submitted or are anticipated within the next few months.

Offshore Electricity Multiple-Purpose Interconnectors

National Grid Ventures – Nautilus Interconnector

Nautilus Interconnector is a proposed second Interconnector between Great Britain and Belgium. In the UK, the offer from National Grid Electricity Transmission (NGET) allows for a connection at a new 400kV substation located close to the Sizewell 400kV network, provisionally referred to as ‘Leiston 400kV’. The current NGET substation location being promoted is less than ten kilometres from the coast. There is currently a public consultation regarding this proposal and the application is expected to be submitted to the Planning Inspectorate in 2023.

National Grid Ventures Limited – Eurolink

EuroLink is a proposal to build a High Voltage Direct Current (HVDC) transmission cable between the UK and the Netherlands.  The capacity of the link will be 1400MW and the project is still in the very early stages of development. EuroLink is a Project of Common Interest as set under ENTSO-E Central European Funding initiative.
