East Anglia ONE Offshore

 

East Anglia One Wind Farm  –   full details about  offshore wind farm construction and project partner 

Also known as EA1, this British wind farm is still in pre-construction and is situated in the North Sea. The project represents a significant investment for ScottishPower Renewables and will be providing green energy to the 530,162 homes it intends to serve. The site is located 43km from the Norfolk Coast and is required to be fully operational by 2020.

The 102 turbines supplied by Siemens provide 10 per cent more energy than the previous model, and collectively the Siemens SWT-7.0-154 turbines will generate 714MW from the site. The robust design and technology was not only constructed to meet the harshest conditions that an offshore wind farm can face, but to prove how enhanced quality can be cost effective.

East Anglia ONE is part of the East Anglia Array, a proposed series of wind farms which comprise the development area which is located 30 miles from East Anglia in England’s North Sea. The East Anglia Zone is one of nine offshore zones owned by The Crown Estate. The Array’s projects will be realised in concert between the primary developers:  ScottishPower Renewables and Vattenfall.

East Anglia ONE represents £2.5 billion worth of investment from ScottishPower Renewables and the company is extremely proud of its level of engagement with UK industries (which account for 50 per cent of the work) and the economic benefits which are being conferred to the east of England as a consequence of the development.

East Anglia Array to be an Unprecedented Powerhouse for the UK

The East Anglia Array will be an enormous complex of wind farms off the coast of East Anglia in the North Sea. In total, 240 wind turbines could be erected, making it the largest offshore wind farm in the world and producing enough power for 4 million homes. Ultimately, there could be as many as six individual wind farms in the Array, but every journey starts with a single step, so East Anglia 1 will be the first of the wind farms to begin generating energy in the demarcated Array area with further phases in the pipeline. InDepth WIND looks at progress to date.

ScottishPower Renewables and Vattenfall to develop East Anglia Array

Developing the East Anglia Array will be a huge task, so ScottishPower Renewables will tackle East Anglia One and Three while Vattenfall gets to work on Norfolk Vanguard and Boreas (still at the Crown Estates’ pre-planning stage). Both East Anglia One (North) and East Anglia Two provoked early interest but are currently in the planning and appraisal process with the Crown Estate at the time of writing. It is anticipated that these leases (EA One [North] and Two) will be awarded to ScottishPower allowing it submit construction plans for consent. The announcement that the developers will focus on specific zones independently follows on changes on the part of the Crown Estate, which prefers to enter into specific project agreements rather than sweeping zone development agreements.

To accommodate this, ScottishPower Renewables will handle the development of East Anglia One and Three, while negotiating with the Crown Estate for other developments in the southern part of the proposed development zone. Vattenfall will focus its energies on East Anglia Four. However, both companies will continue to collaborate and share data. ScottishPower Renewables says this split allows for a 50/50 division of the 7.2GW overall potential of the area.

“We have always believed that the East Anglia Zone has tremendous potential, with some of the best conditions anywhere in the world for developing offshore wind.  Following several years of detailed investigations in the zone, the overall capacity that we hope to build out has not materially changed, which confirms our original optimism. Now we need to move our focus from understanding the wider zone characteristics, which we have done successfully in partnership with Vattenfall, to ensuring that each individual project gets the specific attention that it requires,” said Jonathan Cole, Managing Director for Offshore Wind at ScottishPower Renewables.

The Crown Estate is well-satisfied with the agreement: “Since being awarded exclusive rights to areas of seabed in 2009 to search and identify the best locations to develop offshore wind, developer focus is shifting to the development and delivery of the resulting projects.  We’re working with ScottishPower Renewables and Vattenfall as they progress to project-specific agreements that will mark an important milestone in helping unlock the potential of the East Anglia Zone to deliver large scale low-carbon energy,” said Huub den Rooijen, Head of Offshore Wind at The Crown Estate.

Gunnar Groebler, President of BA Wind at Vattenfall agrees that the arrangement will be the best way forward: “With the agreed development changes in place, we now have two experienced international energy companies focussing their resources on specific projects. This is the most effective and efficient way of taking these major projects forward. This progression in development means that the ability to fully realise the potential of the East Anglia zone has increased. Vattenfall wants to grow its wind business to deliver on ambitious commitments to reduce our carbon emissions. We see offshore wind as a vital sector, and we see the UK as an important market. By developing the northern half of the zone Vattenfall can accelerate regional job creation, delivery of the UK’s climate change obligations and much-needed cost reduction in the sector,” he said.

2016 Marine Survey finds over 60 wrecks and missing WW1 sub

ScottishPower Renewables and Vattenfall made a surprise find in 2016 when using sonar to scan the 6,000 square kilometre area earmarked for the East Anglia Array. The survey team was expecting to find almost all of the 60 plus wrecks, but the WW1 German submarine was an unexpected find. The contractor responsible for the discovery, Netherlands-based Fugro, suggested that the submarine may be a WW2 wreck that had long been sought by the Dutch Navy.

However, an investigation by Dutch Navy divers confirmed that the submarine was, in fact, a German U-31 that went missing in January 1915. The wreck will be treated as an official maritime grave site, and will not be disturbed during the development of the East Anglia Array.

East Anglia One is highly cost-effective and has the most UK content to date

East Anglia One marks several milestones for wind energy. One of its most notable features is its cost-efficiency. ScottishPower Renewables clinched the project with a winning bid of £119 MWh. This will make the cost of energy 15 percent lower than any other offshore wind farm constructed in UK waters so far.

This has been achieved along with another milestone: the highest percentage of local content used in a wind farm to date. “East Anglia One will deliver industry-leading levels of UK content, as well as being the best value offshore wind farm ever to go in to construction. We hope that further major contracts will be placed in the UK in the coming months, adding to the jobs and investment we are already creating in Great Yarmouth, Lowestoft, Hull, Belfast, and Aberdeen,” said Charlie Jordan, ScottishPower Renewables’ Project Director for East Anglia One.

Progress and plans to date

The 714MW East Anglia One already has the green light and ScottishPower Renewables was pleased to confirm that despite the challenging change in circumstances, onshore construction began in January this year. The offshore construction timetable remains on track and work begins in August 2018, with first power in 2019 and full completion targeted for 2020. The initial proposal allowed for the installation of 1,200MW; however, changes in the subsidies schemes have prompted ScottishPower Renewables to proceed with a slightly less ambitious but nevertheless significant target for now.

A contract for one hundred and two 7MW Siemens Wind Power gearless turbines was finalised in April 2016. With nacelles to be built in Cuxhaven and turbine blades made in Hull, there’ll be plenty of the promised local content. Owing to water depths of 30 to 40 metres, jacketed foundations will be used.

The array cables will be 66kV rather than the more usual 33kV cables, and the two 73km long 400kV export cables will make landfall near Felixstowe. Here, a landfall site with transition pits will connect to six onshore cables running north of Ipswich before joining the National Grid at an onshore converter station in the Bramford area. At the same time, additional cable ducts will be laid so that later East Anglia phases can connect to the substation at Bramford without having to repeat excavation works. The laying of these 37km long cable ducts was undertaken by Prysmian UK and began in January 2017.

East Anglia Three and Four will each add a further 1,200MW with each of the two wind farms having up to 172 turbines. Ultimately the East Anglia Array could consist of 1,200 turbines with a target capacity for the zone of 7,200MW. However, only East Anglia One has the go-ahead for the moment.

East Anglia One investment stimulates local economy

ScottishPower Renewables is investing £2.5 billion into East Anglia One, and 50 percent of that will be spent on local content, stimulating the regional economy and providing a significant number of skilled jobs. And, with the output of the windfarm producing the equivalent of the electricity needed to power half a million homes, the importance of East Anglia One to the future of energy in the region is apparent.

East Anglia One North will be handled as a sub-project, with the scoping reports for this development phase having been submitted early this year.

Contractors appointed

Siemens, suppliers of the turbines for East Anglia One is extremely pleased that it has been chosen for the project, Europe’s largest single-contract supply agreement for wind turbines. “Siemens is delighted to work with ScottishPower Renewables on East Anglia One offshore wind power plant. This also represents the largest single order ever for our direct-drive, 7-megawatt wind turbine. The decision to go with our innovative wind turbines underscores the contribution made by these units to reducing the costs of offshore wind power,” said Michael Hannibal, CEO offshore at Siemens wind power.

The company will be using A2SEA’s wind turbine installation vessel, the Sea Challenger, with this portion of the development expected to commence in the summer of 2019.

Apart from the appointment of Siemens to supply, erect and maintain the 102 turbines for East Anglia One, several other major contracts have been allocated. Foundation and pile design have been awarded to Ramboll. The company was founded in Denmark but has a multinational presence spanning thirty-five countries and a particularly strong UK presence. The recommendation of three-legged steel jacket foundations is likely to be confirmed.

Sixty of the 102 steel jackets will be supplied by UAE fabrication and engineering company Lamprell and 24 by Belfast-based Harland and Wolff. The remaining 42 jackets will be fabricated by Spanish state-owned Navantia.

Van Oord, a veteran in offshore foundation transport and installation will use Yarmouth-based marine engineering company Seajack’s advanced Scylla installation vessel to get the foundations into place. The contract is expected to create 75 new jobs.

Rochdale-based Granada joins Siemens in celebrating its largest-ever renewables contract. It will be supplying 103 cranes fabricated using 99 percent UK-made parts. 102 of the cranes will be installed on the wind turbine foundations with the final one being maintained for operator training.

Netherlands-based Royal Boskalis Westminister N.V. subsidiary VBMS will supply, install, terminate, and test the 102 inter-array cables.

Multiple contracts have been awarded to take care of onshore and offshore transmission. Navantia will be fabricating the offshore substation’s topside and jacket while Deep Ocean, based in Darlington, will be fabricating and installing the offshore export cables, supporting 150 local jobs and offering substantial opportunities within its UK supply chain.

Three ports gearing for East Anglia One activity

Ultimately, the port of Lowestoft will serve as East Anglia One’s home base, serving as a centre for operations and maintenance activities throughout the wind farm’s lifespan. During construction, it will be used for offices, provide warehousing, and act as a base for outdoor lay-down as well as a springboard for personnel and a base for coordinating and managing the project.

To this end, a 30-year agreement has been made between the port of Lowestoft and ScottishPower Renewables, and the port is expected to realize £25 million in revenue over the wind farm’s lifespan.

“In Lowestoft, we will manage construction activities and operate and maintain our East Anglia ONE project for at least the next three decades. This will support highly skilled, long-term jobs, both directly and across our supply chain. Every year during the construction phase and operations phase of the project, millions of pounds will be injected into the local economy,” said ScottishPower Renewables Managing Director John Cole.

A second port will be needed to receive components and provide facilities for pre-assembly and pre-commissioning works as the turbines are readied for offshore installation. Peel Ports Great Yarmouth has been selected.

“We are delighted to be working in partnership with ScottishPower Renewables on the large-scale turbine installation programme. The co-investment in the Port of Great Yarmouth further consolidates our position as a leading offshore energy port facility in the UK whilst providing valuable jobs and economic benefits to the region,” said Port Director Richard Goffin. Local government also welcomed the decision.

A third port will be used as a foundations marshalling port, and the Dutch port of Vlissingen provided the most convenient base for these activities.

UK a growth point for wind energy

In January this year, analysts reported that for the first time in its history, the UK generated more energy from wind than coal in 2016. Policy editor at the Carbon Brief, Simon Evans commented on the change: “The past 12 months have seen a year of firsts for the UK’s electricity system. At the broadest level, the UK grid is changing as centralised power stations are joined by thousands of smaller sites, particularly renewables, as part of efforts to decarbonise electricity supplies”.

But with a pledge to eliminate coal-fired power stations by 2025, there is still much to be done, and the sheer number and size of recently completed and in-progress wind farm developments are testimony to the progress that is being made.

As the most ambitious and extensive series of wind farm developments to date, the East Anglia Array is set to make the biggest contribution to UK clean energy yet. ScottishPower Renewables and Vattenfall will be at the forefront, using their extensive experience and unmatched project management skills to drive the mega-project forward one phase at a time. East Anglia One is only the beginning of what will be remembered as an important milestone in the wind energy revolution.
