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.

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. Consent granted March 2022.

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.
