-       Transparency around wind turbine fires is key for industry to demonstrate improved safety record -       New report suggests that without reliable industry-wide data, wind farm owners and operators will lack the baseline necessary to assess and update best practice Scottsdale, 19 October 2020 – The wind industry is committed to reducing the risk of turbine fires according to a new report published by Firetrace, the leading supplier of automatic fire suppression systems. However, while many companies understand that fire is a serious concern for the industry, few are willing to divulge data. This is leading to an industry-wide information deficit on fire reporting, resulting in inefficient risk mitigation and damage prevention strategies. As discussed in Firetrace's latest report, “In the line of fire”, this lack of transparency around fire incidents has ultimately held the industry back from setting up a baseline to continuously improve best practice. The wind industry has rapidly grown not only in the US, but on a global scale, both in terms of total number of turbines installed and the size and scale of these turbines. As such, if the industry is to continue its rapid rate of growth, it must be proactive in demonstrating adherence to health and safety

Siemens Gamesa Renewable Energy (SGRE) statement of testing and approval of nacelle based wind Lidar ‘ZX TM’ from ZX Lidars for the purpose of Power Performance Testing on Siemens Gamesa wind turbines released In connection with a power curve campaign, Siemens Gamesa has tested a new technology together with the well-known company ZX Lidars. Based on the positive results achieved, both on the medium range and long range measurements, Siemens Gamesa Renewable Energy approves the use of the nacelle based Continuous Wave scanning Lidar ‘ZX TM’ from Lidar OEM ZX Lidars for Power Performance Testing. Importantly and in addition to this, operational ‘rotor equivalent’ power curves can also be measured with ZX TM’s unique 50 points around the full rotor swept area, particularly important for turbines with larger rotor diameters offshore and on onshore sites with complex veer or shear profiles. This specific Lidar - ZX TM - allows the power curve of SGRE wind turbines to be measured and verified as a function of the Hub Height wind speed and may be, when agreed with the customer, used instead of the procedure described in the IEC61400-12-1:2017 (ed. 1/ed. 2) using a meteorological mast and anemometry installation. About ZX Lidars (formerly ZephIR Lidar) ZX Lidars provides

An ambitious wind farm in East Ayrshire has been approved by the Scottish Government – and will deliver a host of benefits to the community as well as generating clean, green electricity. Banks Renewables is delighted that its Lethans Wind Farm, east of New Cumnock, has been given the go-ahead, after plans were revised to maximise the supply of electricity. Approval means Lethans’ 22 turbines, at a maximum tip height of 220m, (the tallest turbines granted planning permission in Scotland to date), will have a maximum output of up to 105.6MW. The Hamilton-based renewables employer has worked closely with local independent renewable energy consultant and service provider Natural Power to deliver the project. Both green energy companies have previously worked together on a number of projects to contribute to Scotland’s net-zero pathway. Robin Winstanley, sustainability and external affairs manager at Banks Renewables, said: “This has taken many years of hard work, planning and close consultation with the local community and it is a major milestone to see it over the line. “As well as being a meaningful advance in Scotland’s green energy agenda, approval for Lethans will also deliver real, deep and long-lasting benefits to the local people, the environment and to the

Trelleborg’s applied technologies operation will present a paper on its innovative radar mitigation solution, Frame™, at Global Offshore Wind, a virtual conference and exhibition. As part of the conference program, Dr Adam Nevin will present his paper, ‘Reduce Radar Cross Section Wind Farms: Solving Wind Turbine Radar Interference at Source’ on Friday 30th October, at 12.30pm in the Supply Chain Theatre. One of the ways that Trelleborg is contributing to solving offshore wind challenges for its customers, is with the development of Frame™. This is a unique radar mitigation material designed and developed to reduce the clutter wind turbines cause on radar operator screens. Terry Cooper, Managing Director at Trelleborg’s applied technologies operation in Retford, England, states: “Wind turbines can cause radar interference, showing up on radar operators’ screens as clutter, obscuring the display and resulting in lost aircraft tracking. Our Frame™ material has been developed to functionalize blade resins and fiberglass systems to enable integrated radar absorption. “In many instances, windfarm sites are refused planning permission close to electromagnetic wave based surrounding infrastructures, such as airports. As Frame™ creates a truly robust stealth wind farm, this issue is avoided, facilitating development in previously restricted areas.”   Global Offshore Wind is a virtual online conference and exhibition running across three days from the 28 – 30 October, enabling attendees to hear

Can you name any other energy plant that you build, operate and try to understand if it’s performing efficiently, without actually measuring the fuel that you’re supplying? A wind farm is often exactly that. According to a recent ‘A Word About Wind’ study, almost 50% of those surveyed placed the validation of their production plant as the Number One priority for them – and currently almost half the interviewed were not confident in what’s actually happening with their asset at any given time. Until recent years the cost and complexity of measuring with met masts across a wind farm has made this measure of wind farm ‘fuel’, i.e. the wind, impractical. Nacelle or spinner anemometry is given the challenging job of trying to do its best whilst measuring wind behind, or close the rotor and the disturbed air flow. Add to that site complexity, wakes and turbine array effects… it has meant that estimations of wind speed based on rotor speed, power generation or forecasting are often the only choice. In contrast, Nacelle Based Lidars remotely and precisely measure the wind ahead of a turbine and provide meaningful validations of how wind turbines and wind farms are performing providing information for asset optimisation.

Online trade is the big winner of the Corona crisis. This also applies to the spare parts and repair market for wind turbines. A Hamburg company, a pioneer in this niche in 2013, is now gaining momentum despite, or because of Corona. Stefan Weber, Founder and Managing Director of Windsourcing.com GmbH, shares his thoughts with PES on how the foundation of a digital trading company came about and how much more importance digitization has gained among the broad masses in the context of the Corona crisis. I am an Amazon fan. Please do not misunderstand me. It is completely unacceptable not to pay sales tax from Asian suppliers in Germany and to pay little if any company tax at all. No, I am a fan of focusing on the customers and their benefits: the punctual and fast delivery and using the distribution channel Internet. This enthusiasm has driven me already in 2013 when I founded Windsourcing.com. It was clear to me that digitalization does not stop at renewable energies and here the industry and the entire energy industry can learn a lot from Amazon and Co. Prior to the foundation of the company, I had already been working for many years

No, Wind Energy Asia is vital to the development of the supply chain in Taiwan PES brings you a review of Wind Energy Asia 2020, which took place from March 3rd -5th and a look at forward to the upcoming edition in 2021. In mid-February 2020, as the show approached, the coronavirus spread was heating up and headed straight to be declared a pandemic. Many European exhibitors were having difficulties imagining getting on a plane and flying to an island just 100 plus miles from China, where it all had started and was still far from under control. In Taiwan however, with no community spread to speak of, the virus situation was very much under control. And we knew that, despite the pandemic, renewables continued to need development and that a strong supply chain in Taiwan was critical for the continued development of the industry here. So, despite the many skeptics, we went ahead. And were rewarded grandly! All our numbers were up handsomely, yes, up, in 2020, imagine, compared to 2019: • 52.8% more companies exhibiting, 136 in total. About 10-15 others canceled days before due to the pandemic • 13 countries and 8 pavilions: up from 6 last year • Exhibition area grew 29.7%

If a leopard could not change its spots, it would have long been extinct had it been masquerading as a vessel owner in the offshore industry! ‘It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.’ —Charles Darwin An inability to adapt to changing surroundings has repeatedly been the downfall of those incapable of moving forward. You only need to look at companies such as Kodak and Blockbuster to see what can happen if you are unable or too slow to embrace change. Bringing things closer to home, shipping in general and offshore specifically has been hard hit over the past few years by a sustained oil-price crash, compounded by the current global COVID-19 pandemic. These events have shone a critical light on not just the way we do business, but on life as we know it – and this is not said lightly. The devastation from the pandemic has already left its mark on hundreds of thousands of individuals and families, whilst the economic fallout from the current crisis will be deep, far-reaching and undoubtedly leave many casualties in its wake. Change is definitely on

With the increasing trend toward cleaner energy sources, offshore wind technology plays a vital role in supporting the global transition to renewable energy. Development of shallow water locations is increasing in volume and pace, with the industry moving toward the more substantive wind energy resources that are found offshore in deeper waters, through the application and development of floating offshore platform technologies. By 2025, it is anticipated that close to 20,000 turbines with 250 plus offshore substations will have been installed offshore. Even with the development of larger turbines, these quantities are expected to increase by a factor of three plus by 2050*. Critical to their successful operation are the subsea power cables that have the essential function of transmitting generated power from the turbines to the substations (electric hub of the windfarm), and then onward to shore. Digitization in renewable energy Digital technology development continues at a rapid pace, increasing in functionality and accessibility, while supporting gains in productivity, efficiency, visibility, and informed decision making. With growing competition in renewable energy markets and ever more remote and demanding deep-water conditions, the renewables industry is looking at advanced digital solutions to enable new efficiencies and maximize return on investment.
