This briefing is intended as an update on three key policy and case law developments that have taken place over the summer. 1 New European Court ruling – ‘Sweetman II’ On 25 July 2018, the Court of Justice of the European Union (the Court) delivered its ruling in the case of Edel Grace and Peter Sweetman v An Bord Pleanala, or ‘Sweetman II’ (also known by some in the industry as ‘People over Wind II’.) The judgment developed the position taken in People Over Wind and Peter Sweetman v Coillte Teoranta (‘Sweetman I’), delivered in April this year. The Court again focused on the interpretation of Article 6 of the Habitats Directive, which concerns the need for an appropriate assessment where a project is likely to have a significant effect on a site (onshore or offshore) designated as a special protection area or a special area of conservation (SPAs and SACs) The key question for the Court was at what point in the assessment under this Directive should mitigation measures be taken into account. Current practice relating to appropriate assessment is based on a four-stage approach. Briefly, these stages are: (i) Screening to establish whether a likely significant effect may exist on the integrity of a

Morten Huseby, CEO at Wirescan, shares his enthusiasm for their new digital service with PES. The company is set to launch its Wirescan Digital platform and Wirescan GO!. These are exciting times and the beginning of a new era for this dynamic, forward thinking company. PES: Hi Morten, welcome to PES Wind magazine, it’s good to talk to you. Would you like to begin by giving us an overview of Wirescan and how it has changed over the past 12 months? Morten Huseby: Wirescan is changing from a traditional ‘box-pushing’ to a digital service-based business model, with the capability of collecting test data from de-energized and energized cables. Wirescan can now offer condition assessment and monitoring services throughout the whole cable lifetime. The ability to gather and structure huge amounts of data is opening a whole new world of possibilities within predictive analysis. Look at the Tesla autopilot accident prediction module. By ‘replacing’ the human mind as the decision maker, Tesla’s autopilot gathers huge amounts of real time data, which is processed to keep the vehicle not only on the road at the right speed, but also to assess complex traffic situations to automatically predict and avoid any unwanted events.

Alan Gooding, director and co-founder of Smarter Grid Solutions, explains that the secret to harnessing offshore wind lies back on dry land. The growth of offshore wind power is nothing short of astounding. The UK’s capacity already sits at 8GW, with 2GW added during 2018 alone, and energy minister Claire Perry wants that total to rise to 30GW by 2030, enough to provide a third of the electricity Great Britain needs. Engineers are already rising to the challenge of installing scores of turbines around the coast. Yet harnessing the full power of the wind out at sea will also require changes in the way the electricity system is managed back on dry land. As anyone who’s ever stood on a beach can testify, the wind doesn’t blow at a constant speed all day long – sometimes it comes in strong gusts and sometimes it drops completely, leaving a perfectly still day. That intermittency sits at the heart of the challenge of integrating offshore wind. Wind farms can be spread out along the coast to help smooth out some of the variability in the wind; after all, if it’s a calm day down in Cornwall then the wind may still be blowing up in

A quick and easy AC solution, or a highly sophisticated connection using DC technology? The best transmission solution for offshore wind parks depends on both distance and output. But cost is key: for both technologies, Siemens is putting all its development efforts into downsizing and standardization, in order to minimize installation and operational costs. It started off as the most expensive renewable energy solution, but offshore wind has experienced many improvements to its efficiency over the last ten years. Innovations in the turbines themselves, for example, more optimally sized rotors and a higher hub height, have significantly increased their annual energy production and led to substantial savings in the cost of the turbine foundations and construction. Industry association WindEurope estimated that, combined with other technology improvements, this may account for at least 20 percent of the levelized cost of energy (LCOE) by 2030. ‘Current innovations in electrical transmission and grid connections for offshore wind will have a similar if not even greater impact on LCOE,’ says Andreas Barth, Head of Grid Access in Large Transmission Solutions at Siemens Gas and Power. ‘We’re minimizing platform size for grid connections, and our transmission links account for lower energy losses. Ultimately, our customers can

If you are a service provider within the wind industry, you do definitely have a lot of equipment that needs to be inspected regularly. This could be PPE equipment, hand tools, measuring instruments, hydraulic tools, torque wrenches, lifting gear, rescue equipment and much more. In addition, there are all the training certificates that your employees must have, in order to carry out their work for your company. Many try to keep track of the above by using a self-developed EXCEL sheet, but as soon as the person, who has developed the sheet leaves the company, no one else can work it out. At the same time, EXCEL does not provide a great overview. Therefore, many service providers have chosen to gather the management of the above into one and the same system, namely READUNIT. Readunit is the leading tool management software in the wind industry; the system provides a great overview of all the equipment and the certificates that you enter into it. Fantastic and instant overview Readunit provides a constantly updated overview of the status of all equipment. Locations can be set up to keep an overview of equipment. A location can be a customer, a site, a service vehicle, or an

What once seemed like a pipedream has become reality. Offshore wind projects worldwide have increased in number, and are now becoming more of the norm. What has not gone away is the citizen opposition to wind farms, which now has spread to offshore projects worldwide. Recent studies on global offshore wind show strong growth. If the headwinds of opposition can be tampered on projects, more and more will gain approval and go online. Opponents seem confident about slowing projects down, and are coming from all areas and vantage points with their vocal opposition. Take for example the Atlantic sea scallop. For the northern Atlantic area of the United States, there is an area called the New York Bight, which contains hundreds of millions of dollars of fish, of which around 80% are scallops. Fisherman in this area are cautious, however early stakeholder outreach can yield positive results. Opposition also to the cables going onshore with power have felt their presence in Happisburgh, with the Norfolk Vanguard project off the coast of England. This is the second project in three years that is in need of land to run cables through, and some residents are banding together to stop this. In the Great

For those working in the wind sector, the risks of arc flash incidents have always been better understood than in many other industries. Working with extremely high voltages and large currents on a daily basis, means that knowledge across the sector is noticeably higher compared with similar industries that are also at risk of the danger. However, it appears that there’s a new danger emerging when it comes to arc flash, which takes the shape of a false sense of security. What is an arc flash? Most of us in the wind industry are familiar with an arc – an electric luminous bridge formed in a gap between two electrodes – but its severity and danger are often overlooked. An arc flash occurs during a fault, or short circuit condition, which passes through an arc gap, and can result in devastating results if the correct equipment isn’t being worn. Arc flashes can occur for several reasons, and their frequency is somewhat alarming. From being initiated through accidental contact or equipment that is underrated for the available short circuit current, to contamination or deterioration and corrosion of equipment, these are just a few of the many causes of an arc – making the risks higher

The Port of Grenaa has grown from a small fishing port to an international hub, with the capacity and know-how to serve the offshore wind market. The pre-assembly facilities, the ease of access and experience, makes it the ideal port to access Denmark, Sweden and Northern Europe. Theis Gisselbæk, the CCO, gives PES an insight into its growth. PES: Welcome to PES Wind magazine, it’s great to talk with you. It would be great if you could give us some background on the Port of Grenaa. Theis Gisselbæk: The Port of Grenaa has a long history, and it celebrated its 200th anniversary in 2013 at the same time as the installation of the Anholt offshore wind farm. In the early beginnings Port of Grenaa was primarily a fishing and ferry port. Over the years the port has broadened its work to especially bulk activities. Our latest big port expansion was inaugurated in 2010. The planning of this development process started at the end of the 90-ties. The wind industry has always been a natural part of our portfolio. Nordtank, a local company, is now, after several mergers, part of the Vestas group. The Port of Grenaa also has a long tradition
