Construction of the Neart na Gaoithe (NnG) offshore wind farm is now underway following confirmation from EDF Renewables that financial close for the project has been achieved. Twenty-five (25) financial institutions are lending money to fund the wind farm which will supply enough low carbon electricity for around 375,000 homes*. For more information see the IDTechEx report on Energy Harvesting Microwatt to Megawatt 2019-2029.
EDF Renewables is also announcing that leading Irish energy company ESB is taking a 50% stake in the project.
EDF Renewables UK CEO Matthieu Hue said "These are hugely important milestones for the project, and a great credit to the EDF Renewables team. We are excited to get work under way with our new equity partner ESB, our contractors, and all Scottish companies and stakeholders participating in the project. The 450 MW NnG project will play an important role in de-carbonising the UK electricity system and is a further example of EDF Renewables continuous investment and growth in Scotland."
Pat O'Doherty, Chief Executive of ESB, says that the significant acquisition represents another key milestone in the company's investment in offshore wind. "Our 50 percent stake in Neart na Gaoithe fits entirely with ESB's Brighter Future strategy to build a balanced low carbon generation portfolio of scale. Offshore wind is one of the main technologies underpinning the clean electricity systems that will power our societies into the future. This investment in the Neart na Gaoithe project builds on significant ESB involvement in offshore wind off the Irish coast as ESB develops its experience to assist Ireland deliver its Climate Action Plan. We look forward to pooling our expertise with EDF Renewables in delivering this major project."
Following successful development of the site, NnG will now move in to a full lease with Crown Estate Scotland to allow the construction and operation of the wind farm.
Investment in Scotland
NnG has a capacity of c. 450 megawatts (MW) of low carbon energy and will offset over 400,000 tonnes of Co2 emissions each year. Construction of components is now underway, offshore construction will start in June 2020 and full commissioning will complete in 2023. NnG will bring a further boost to the offshore wind industry in Scotland, providing new jobs and manufacturing opportunities. EDF Renewables UK has already increased its Edinburgh team from 44 people to over 100 people at the Atria One building in Scotland's capital city.
All of the project's 54 turbines will be assembled at the Port of Dundee before being sailed to the site and the Scottish engineering firm BiFab will build a number of the foundation jackets. Project servicing and maintenance will take place at the Scottish NnG Operations and Maintenance base where there will be 50 permanent jobs over the 25-year lifetime of the wind farm. The preferred supplier at this stage is Eyemouth Harbour.
NnG Project Director Matthias Haag said, "It is a great day and we look forward to working with all the teams on what will be a fantastic project for Scotland and for EDF Renewables. Each of our main contractors will be introduced to further Scottish contractors through the Forth and Tay offshore cluster which we have supported since it was formed this year. It is designed to maximise local supply chain and employment opportunities as much as possible."
The Scottish Government's Finance Secretary Derek Mackay said: "This is positive news for the Port of Dundee, Eyemouth Harbour and BiFab in Fife, which are set to benefit from the associated jobs and investment in the local community, demonstrating the strengths and potential of our indigenous supply chain. The Scottish Government is actively encouraging developers to explore every possible option to help the Scottish supply chain in the development of future offshore wind projects. While we believe that much more is possible from across the whole sector, today's announcement is another welcome step in the right direction."
Charles Hammond, Group Chief Executive of Forth Ports, said: "This is great news for Dundee and we look forward to working with EDF Renewables and Siemens Gamesa on this major development that will bring significant benefits to not only the City of Dundee and the port but the whole of Scotland. Continued investment in our facilities, skills and infrastructure along with our £10m industry-leading heavy lift quayside means the Port of Dundee is well placed to deliver this prestigious offshore wind infrastructure project."
Councillor John Alexander, Leader of Dundee City Council said; "In partnership with Forth Ports and private sector partners, we have been actively promoting the skilled workforce, facilities and opportunity that exists at the Port of Dundee. I am delighted with this latest announcement that recognises those huge assets. It's an incredible vote of confidence for Dundee but importantly, the relationship with the NNG team, EDF and Siemens Gamesa will be a source of strength long into the future. As leader of the city, I cannot underestimate the importance of this announcement."
Christine Bell, Business Manager at Eyemouth Harbour Trust said, "Eyemouth being selected at this stage represents an exciting new chapter for the town, one which will potentially stimulate economic growth and inward investment, adding value to what the town already has to offer. This transformational and inclusive renewable energy project will create new long-term jobs, investment and opportunities for the next generation and beyond. We welcome EDF Renewables and their partners to our community as we begin the next phase of feasibility work."
Tier One contractors
EDF Renewables also is announcing some of the project's Tier One contractors. The NNG offshore wind farm will have fifty four (54) eight (8) MW wind turbine generators (WTG) which will be supplied by Siemens Gamesa Renewable Energy (SGRE).
The foundations for the turbines will be supplied and installed by Saipem. There will be fifty four (54) WTG foundation jackets with a number being made by BiFab. These are used to support and anchor the WTG's to the seabed. Saipem will also supply and install and additional two (2) jackets for the offshore substations (OSS).
Prysmian Group will supply and install the export cable, both offshore and onshore. Two offshore export cables, approximately thirty seven (37) km long, will connect the OSS's to Thorntonloch Beach in East Lothian.]. The onshore cable will connect the offshore cables to the onshore substation located at Crystal Rig in the Lammermuir Hills, approximately twelve point three (12.3) km away.
DEME Offshore has won the contract for engineering, procuring, constructing and installing (EPCI) the inter-array and interconnector cables with offshore installation expected in 2021.The layout will include twelve (12) separate sixty six (66) kV array strings, connecting the WTGs to the OSSs in three (3) loops to each OSS. The interconnector will connect the OSSs together and allow WTGs to export electricity through the export cables.
Fred Olsen Windcarrier will be delivering the transportation and installation of the WTG's with offshore installation expected in 2022. The vessel Blue Tern will be used for the works with the Port of Dundee as the loading harbour for the wind turbines.
Colin Palmer, Director of Marine for Crown Estate Scotland, said: "The move forward to a full lease marks a significant milestone in the development of Neart na Gaoithe, and is testament to the hard work undertaken to ensure this project comes to fruition. Offshore wind developments like this have the potential to help Scotland achieve our net zero ambitions and enable wider socio-economic benefits for communities."
CEO of SGRE's offshore Business Unit, Andreas Nauen said "Receiving the confirmed order for the Neart na Gaoithe project from EDF Renewables is excellent news for Siemens Gamesa. We're fully prepared to deliver our reliable SGRE offshore Direct Drive technology, and to play our part to deliver clean energy when the project is in operation."
Francesco Racheli, COO of Saipem's E&C Offshore Division said, "This contract marks a key step in the pursuit of our strategy to become a key player in the realization of large offshore windfarm developments and, more extensively, in the sphere of the energy transition. This important achievement has been made possible thanks to our engineering, fabrication and installation capabilities and expertise. Our collaboration with EDF and with the entire supply chain, will allow us to participate in the development of a significant project in the renewable energy sector."
