Kentish Flats Extension

In May 2010, Vattenfall was offered the opportunity to extend Kentish Flats Wind Farm by The Crown Estate. The Crown Estate leases the seabed to wind farm developers on behalf of the UK Government.

Vattenfall assessed the feasibility of the project and decided to seek consent from the Planning Inspectorate (formerly IPC) to extend the existing  Kentish Flats Wind Farm.

Vattenfall then began extensive discussions and consultation with the local community, local authorities and statutory consultees

Kentish Flats

Due to the size of the infrastructure, the application was considered by the National Planning Inspectorate. Public hearings took place in May 2012 and, after consideration, the Inspector submitted his recommendation to the Secretary of State.  On 19 February 2013 Vattenfall was granted consent to extend the 30-turbine scheme by up to 17  turbines.  (For a full digital recording of the public hearings and the application process, please log on to the link below)

This means that the extension itself will be capable of generating up to 173,000 megawatt hours (MWh) of clean electricity every year, which is equivalent to the total annual electricity needs of up to 42,196 UK households*. The extension will be constructed more than 7km from shore and will cover nearly 8 sq km.

The existing Kentish Flats Offshore Wind Farm has been generating clean electricity since 2005. Find out more about this project by visiting:

The construction timetable is now in place and Vattenfall will commence onshore works in Autumn 2014. A public consultation will be held in 2014 with local residents and regular updates provided.

The development itself will consist of 15 3.3 Megawatt turbines which will provide an additional maximum installed capacity of up to 49.5MW. Offshore works will commence mid-2015.

*Based on Department of Energy & Climate Change data for average annual UK household electricity consumption of 4,266 kilowatt hours.

Norfolk firm wins offshore wind contract

A Norfolk firm specialising in the protection of seabed infrastructure has started supplying to a wind farm off the Kent coast.

Subsea Protection Systems (SPS) has started supplying 255 concrete mattresses to Vattenfall’s extension of the Kentish Flats Offshore Wind Farm, approximately 7 km off Whitstable and Herne Bay. The Great Yarmouth company, which employs 20 in the town, will transport approximately 1,250 tonnes of concrete mattresses to the site which will be used to protect cables used by Vattenfall’s Kentish Flats Offshore Wind Farm. This will allow the ‘overlaying’ of new cables from the extension when installed next year.

The offshore wind industry has grown significantly in the UK in the past ten years and a major supply chain is emerging. According to industry trade body RenewableUK approximately 13,000 jobs are currently supported by the offshore wind sector. If offshore wind delivers it potential this could grow three-fold to more than 40,000 people by 2023.

Matthew Green, Vattenfall’s Project Director for Kentish Flats Extension, said: “Vattenfall is committed to maximising contracting where it can with local and UK business and we’re pleased that Subsea Protection Systems has started supplying concrete mattresses to Kentish Flats Extension.”

Subsea Protection Systems is being subcontracted by Bohlen & Doyen (BoDo), the main contractor responsible for laying 30km of cable between the 15 turbines and from the scheme to shore. SPS has already supplied to several other wind farms in the North Sea.

John Gorman Business Development Manager for SPS said: “SPS have made a substantial investment in Great Yarmouth to support the UK’s offshore wind sector. It has been a pleasure working with Vattenfall and the Bohlen & Doyen team in designing the correct specification of mattresses to ensure the protection of the cables at Kentish Flats Offshore Wind Farm.”        

Rene Fischer, Project Manager for BoDo, said: “We are delighted to be working with Subsea Protection Systems.  SPS have a great track record in this field of expertise and their flexible and adaptable approach to work has been of real benefit on this project. Not only is it good to work with a UK company but it is useful that they are conveniently situated near to a port making transportation of goods that much easier.”

In the spring Vattenfall will install foundations seven kilometres offshore and these will be followed by the delivery and erection of the 139.6 metre high wind turbines.  All 15 turbines are scheduled to be deployed by August 2015.  Kentish Flats Extension hopes to generate first power in early September with all turbines operating by December 2015. Kentish Flats Extension will be capable of generating enough power in a year to meet the equivalent annual electricity demand of 35,000 households.
