Development Consent Order
Large projects such as Wylfa Newydd are known as Nationally Significant Infrastructure Projects (NSIPs). They require a Development Consent Order (DCO) application that is determined by UK Government. Horizon has applied for a DCO from the UK Secretary of State for Business, Energy and Industrial Strategy.
The DCO process is managed by the Planning Inspectorate (rather than the local council which considers traditional planning applications), and provides opportunities for stakeholders to comment on the application.
Visit the Planning Inspectorate’s website for more information about its process.
