Some would argue that the offshore wind industry is the epitome of efficiency. Wind turbines keep getting bigger and bigger, which appeared impossible just a few years ago, resulting in reduced levelized cost of energy. The pioneers within the sector can collectively argue that they have started a coevolution towards decarbonation and a greener world.   Meanwhile, it is the phenomena of how constant efficiency and cost reduction drive the offshore wind market that is interesting. How and when is the optimum achieved, as this could be the point where the offshore wind industry will develop fastest. These questions puzzled the management of Port Esbjerg, which has been used as an installation port for nearly two decades and therefore has observed the changes. They believe the future is hyper-collaboration, between ports and between companies servicing the offshore wind industry. There are numerous examples of the sharing economy in operation at the port. A prominent example involves one of the largest fleets of mobile harbor cranes. The port owns and operates the cranes that are used by both manufacturers of major components for offshore wind turbines and the various stevedore companies operating in the port.

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

The anti-icing blade heating technology is the enabler for windfarm power production in extreme icy conditions in Quebec, Canada. The efficient use of heat keeps the turbines operating up in the mountains, in the most demanding, freezing conditions, such as Lac Alfred wind farm. It consists of 150 wind turbines, with total capacity of 300MW and is located up in the mountains of Gaspe peninsula, Quebec. The wind farm is heavily influenced by the proximity of the Atlantic Ocean. It has vast wind resources, but the combination of moisture rising out of the sea that stays open the whole wintertime, high altitudes and the cold weather means the environment is prone to icing conditions. The winter is long and usually starts in October and ends in April. The turbines tend to stop easily if any ice is detected by their sensors. Many of the turbines here suffer heavy icing, which leads to long periods of complete standstill. This leads to losses of about 15% of the annual energy production, AEP. It was obvious that something needed to be done in order to save the investment. ‘Until the summer of 2016 we had only used our blade heating technology on new turbines,’

The 2nd offshore wind boom is upon us and this time it is going global. During 2021 project installation will be underway in UK, Denmark, Germany, Netherlands, Belgium, France, Norway, Spain, Portugal along with US, Vietnam, Taiwan and China. By 2025 many more countries will join this rush to install the cheapest form of largescale renewable power available. The last 10 years of this sector has been about major efficiency gains. This has been brought about by giant leaps in generating capacity, huge economies of scale and general efficiency throughout the supply chain. Turbines can now be erected and commence operation within 24hrs or less. Installed redundancy has reduced the need for regular intervention. Key failure points have been removed. All of these and many more have helped offshore wind find its place as the keystone within the generation mix for decades to come. With this in mind, and looking to further enhance the efficiency of this green industry, one must note that the means of access to these offshore farms heavily relies upon a marine logistics fleet which currently has a hefty carbon footprint. Whether it be the installation vessels, survey boats, cable layers, jack-ups, SOVs, CTVs or helicopters, the amount of

As we move towards net zero carbon emissions targets, significant efforts to connect more clean energy resources to the grid are being made. Globally, the energy industry is welcoming innovations in renewable energy and Distributed Energy Resource (DER) assets. As a result, correctly managing and distributing the energy from these DER assets to enable the most efficient, clean and smart energy system is a big focus for system operators, utilities and asset owners alike. Big strides have been made already in the capabilities of energy storage and distribution networks, with major projects testing long-term battery models. A recent study by Wood Mackenzie revealed that it is expected that cumulative capacity of distributed storage and solar in North America, Europe and Oceania will double by 2025. Similar predictions were made by The International Renewable Energy Agency (IRENA) who project that the onshore wind capacity growth rate will quadruple to more than 200 GW added annually by 2040. Renewables by nature are intermittent. The sun does not always shine and the wind does not always blow. Add to that, the current uncertainty over the long-term implications of the Covid-19 pandemic and subsequent lockdowns and economic changes on electricity demand, there are many

Wind industry business models are shifting their focus. They used to be mainly driven by financial aspects of the business plan and the debt used to finance it, while technical operations, often subcontracted, came in second place. The priority of the wind industry was to ensure robust turbines with a high degree of availability, with performance being considered secondary. This happened mainly for three reasons: 1. High electricity resale prices were guaranteeing comfortable margins. 2. Technical skills were not always available or easy to acquire by the owners and asset managers 3. Digital data was of poor quality, often difficult to use because it was controlled by the turbine manufacturers. The gradual disappearance of feed-in tariffs and the implementation of reverse auction systems are giving the market a different dynamic, with the main consequence being a significant drop in the resale price of electricity. Average prices have decreased by 50% in the last 8 years, directly impacting the wind farms Return On Investment (ROI). Nevertheless, this drop in the price of electricity is an excellent opportunity for the industry, as it makes wind energy more competitive within the energy mix. The influx of capital has been unstoppable, and has even led to a

All over the world, people are asking two questions: How will COVID-19 have a continued effect, and what will the next American President do? The pandemic has caused manufacturing plant closures resulting in predictable havoc, but we have also seen COVID-19 disrupt supply chains that were once rock-solid, in ways nobody could have anticipated. It’s uncertainty on top of uncertainty. ‘Nobody believes we’ve seen the end of what the pandemic will do to the global economy and the various industries that drive it, but we have always thrived in adversity and uncertainty,’ says an optimistic Randall Sullivan, Chartering Manager, BBC Singapore, ‘and our customers know we’ll work right alongside them to find our way in the ‘new normal’. Supply chain disruptions resulting from COVID-19 have already caused problems for our clients, and they’ve been coming to us for innovative solutions to their rapidly changing transportation needs. We’ve been able to solve difficult supply problems, sometimes on very short notice, because we’ve got the ships and the people to do it. A fleet like ours allows us to mitigate schedule changes that arise from sudden changes in production’. Who will be the next American President, and what will he do? What
