East Anglia ONE North

ScottishPower Renewables is investigating the potential for a new offshore windfarm project in the southern North Sea, called East Anglia ONE North.

Infographic: 800 megawatts
Infographic: windfarm area 208 square kilometres

The proposed offshore windfarm site to be developed by East Anglia ONE North Ltd, is located in the southern North Sea, approximately 36km from its nearest point to the port at Lowestoft and 42km to Southwold. The proposed East Anglia ONE North project would have an operational capacity of up to 800MW [1], which is enough to power approximately 659,922 [2] UK households.

The Project

The proposed East Anglia ONE North Offshore Windfarm has the potential to make a substantial contribution to UK 2030 energy targets by meeting nearly 5% of the UK offshore wind cumulative deployment target for 2030.

The proposed offshore development area comprises of:

  • Wind turbines – up to 67 wind turbines would cover an area of 208km [2]. The maximum height to the blade tip would be 300m above sea level.
  • Offshore platforms – up to four electrical platforms connected by platform link cables to collect the electricity, a construction, operation and maintenance platform and a meteorological mast.
  • Subsea cables – inter-array cables connect the turbines to the offshore electrical platform. A maximum of two export cables, buried or protected on the seabed will then transport the electricity to shore. The two cable routing options are the preferred choice in terms of engineering and environmental constraints, in particular avoiding the geological Coralline Crag sea bed feature. 

The onshore development area comprises of:

  • Landfall location – Horizontal Directional Drilling (HDD) will be required to install the ducts to avoid any construction works on the beach, and a minimum setback distance of 85m from the cliff top will allow for natural coastal erosion based on the potential 100-year erosion prediction and will not compromise the integrity of the cliff. 
  • Underground cables – up to six single core onshore cables and up to two Fibre Optic cables will be buried for a maximum of 9km. For the majority of the route, trenching will be undertaken in which to place the ducts through which the cables are pulled. Manhole covers may be required at some locations to allow for maintenance.
  • Public highways – a number of road improvements or modifications could be required to facilitate the ingress and egress from the public highways for construction access or at locations on the existing public road network in order to facilitate construction traffic and/or construction-related deliveries.
  • Onshore substation – a maximum building height of 15m and external electrical equipment of up to 18m in height is proposed and the substation will cover an area of 36,100m2 (190x190m).  
  • National Grid substation – Onshore substation – a maximum building height of 15m and external electrical equipment of up to 18m in height is proposed and the substation will cover an area of 36,100m2 (190x190m).  
  • National Grid substation – to accommodate the electricity produced by East Anglia TWO (and East Anglia ONE North) an Air Insulated Switchgear (AIS) or Gas Insulated Switchgear (GIS) substation would be required. The maximum height of the AIS would be 13m with a footprint of 145x310m and the maximum height of the GIS would be 16m with a footprint of 140x120m.
  • National Grid realignment works – up to one additional pylon within the vicinity of the National Grid substation as well as up to two cable sealing end compounds, up to one cable sealing end (with circuit breaker) compound, and potentially additional strengthening or modification works within the overhead line realignment works area will be required for East Anglia TWO (and East Anglia ONE North).


[1] As measured at point of connection of the onshore cables to the onshore substation
[2] Calculated taking the number of megawatts (900) multiplied by the number of hours in one year (8,766), multiplied by the average load factor for offshore wind (33.36%, published by the Digest of United Kingdom Energy Statistics), divided by the average annual household energy consumption (3.781MWh), giving an equivalent of powering 800,416 homes.
