Nationally Significant Infrastructure Projects

Nationally Significant Infrastructure Projects or NSIPS are large scale developments (relating to energy, transport, water, or waste) which require a type of consent known as “development consent”.


The Planning Act 2008 introduced a new development consent process for NSIPs. A Development Consent Order (DCO) removes the need to obtain lots of separate consents, including planning permission.


More information about the Development Consent Process is available from the Planning Inspectorate website.

The Suffolk Coast has been identified as the preferred location for the delivery of a number of large scale renewable energy projects.

A new nuclear power station, Sizewell C is being proposed immediately adjacent to the existing Sizewell B nuclear power station at Sizewell village. In addition to Sizewell C, a number of new offshore windfarms are being promoted off the Suffolk Coast.

In addition to East Anglia ONE, which is already under construction, Scottish Power Renewables are now promoting East Anglia One North and East Anglia Two offshore wind schemes.

As well as the above projects, Inology is commencing planning on the Five Estuaries offshore windfarm, which is an extension to Galloper, while proposals for an Interconnector project between the Netherlands and the UK ( Eurolink) and another Interconnector project between Belgium and the UK (Nautilus) are also under consideration by National Grid Ventures.


All of the above have the potential to significantly impact on the natural beauty and special qualities of the Suffolk Coast & Heaths Area of Outstanding Natural Beauty (AONB). More information about the separate NSIPS in Suffolk is set out below.
