The plans would add another major energy infrastructure project to those already proposed across Suffolk.
The proposed development would comprise of 32 wind turbines up to 220 metres in height, together with associated battery energy storage infrastructure, across parts of Suffolk, Norfolk and Cambridgeshire.
Vattenfall UK intends to bring forward the scheme as a Nationally Significant Infrastructure Project (NSIP). This means the final decision on whether the project is approved will be taken by the Secretary of State for Energy Security and Net Zero, rather than Suffolk County Council (SCC).
As a statutory consultee in the planning process, SCC will review the proposals in detail, working alongside neighbouring authorities and other stakeholders to ensure the interests of Suffolk communities are fully represented. The council's responsibilities will include scrutiny of issues such as highways, flooding, archaeology, public health and fire and rescue services.
The developer has also begun consultation on the scope of the Environmental Impact Assessment (EIA), which will examine the potential effects of the project on local communities and the environment.
SCC is encouraging town and parish councils, residents and local organisations to take part in the consultation processes and ensure their views are heard.
Councillor Tristan Gale, Suffolk County Council's Cabinet Member for Planning, Devolution and the Fire Service, said:
"Yet another blow for Suffolk residents. These proposals are unprecedented in scale for an onshore wind farm and would add further pressure to communities already facing an extraordinary concentration of major energy infrastructure.
"The tallest wind turbines in England currently stand at 150m, these would be gargantuan and seen from miles around whilst impacting on aviation from nearby military airbases.
"Enough is enough. Suffolk cannot continue to absorb project after project without a full assessment of the cumulative impact on local people, the countryside and our economy.
"We will not simply wave these proposals through. As a statutory consultee, we will scrutinise every piece of evidence, challenge the developer where necessary and fight to ensure our county’s interests are protected.
"A development of this scale could have lasting consequences for agricultural land, already impinged wildlife, rural communities and the landscape itself. I urge residents, businesses and local councils to have their say."
