Three nationally significant infrastructure projects given development consent

Three Nationally Significant Infrastructure Projects (NSIPs) have been granted development consent. 24 projects have now received development consent since the start of the regime.

All three projects, Thames Tideway Tunnel (super sewer), the Clocaenog Forest Wind Farm in north Wales and the North Killingholme Power Project, were examined by the Planning Inspectorate and recommendations made to the relevant Secretary of State. Every part of the process was completed within the statutory timescales laid down in the Planning Act 2008 (as amended by the Localism Act 2011) following substantial public engagement.

The Planning Inspectorate’s Chief Executive, Simon Ridley, said:

“All three applications were submitted to the Planning Inspectorate within days of each other. The examinations were completed and recommendations made to the relevant Secretary of State within the timescales prescribed in the Planning Act.”

“These decisions demonstrate the increasing strength and importance of the National Infrastructure regime. The Planning Inspectorate is fulfilling its responsibilities by undertaking thorough, impartial examinations and ensuring full community consultation within statutory deadlines. The certainty of knowing when a decision will be made following full consideration of public views provides developers and investors with the confidence needed to plan the infrastructure improvements this country needs to secure future economic growth.”

Documentation, including the decision, the recommendation made to the Secretary of State and the evidence considered by the Examining Authority in reaching its decision, is publicly available on each project’s page of the National Infrastructure Planning website:

More than 1,200 representations from interested parties were considered and in excess of 400 written questions were asked by the Examining Authority.

  • Clocaenog Forest Wind Farm application is the 11th generating station scheme, the 7th wind farm project and 2nd onshore application consented through the national infrastructure regime. It has the highest onshore wind farm generation capacity of up to 96MW consented through the national infrastructure regime.

  • North Killingholme Power Project - A new thermal generating station that will operate either as a Combined Cycle Gas Turbine (CCGT) plant or as an Integrated Gasification Combined Cycle (IGCC) plant, with a total electrical output of up to 470MWe. It is the 10th energy project to be given planning consent under the Planning Act 2008 and is the 1st gas fired power station to be examined by the Planning Inspectorate.
