Nationally Significant Infrastructure Projects (NSIPs)

The Planning Act 2008 defines and establishes a process for examining NSIPs which would previously be consented by different government departments.

The need for these schemes is established in National Policy Statements and the purpose of the process is to weigh the local impacts of the scheme against the national need for such infrastructure in a fair, open and impartial manner.

The stages of the decision-making process for NSIPs are explained below:

The process | National Infrastructure Planning (planninginspectorate.gov.uk).

SCC is a statutory consultee as a host authority in respect of a number of NSIPs and therefore has an important role to play in Pre-Application, Acceptance, Pre-Examination, Examination and Post Decision Stages.

The County Council’s position on each NSIP is informed by its Energy and Climate Adaptive Infrastructure Policy (see separate web page below).

SCC guidance on Planning Performance Agreements (PPAs)

Suffolk County Council (SCC) expects of all NSIP developers in Suffolk to enter into a Planning Performance Agreement; our guidance about SCC’s expectations for Planning Performance Agreements (PPAs) for Nationally Significant Infrastructure Projects (NSIPs) is published in the PPA policy document.

NSIPs in Suffolk

The list below refers to current live NSIPs proposals, which are at various stages from pre-application to construction.

Each NSIP page includes a brief description of the proposals, links to the developer’s website and the dedicated section of the Planning Inspectorate (PINs) website for the schemes. Downloadable copies of SCC’s formal responses to consultations, Local Impact Reports and Relevant Representations can also be found, where available.
