PES ESSENTIALSEEDS OFOPTIMISM Words: Michael Phillips, Principal Consultant at renewable energy consultancy, Dulas The state of flux in the UK’s onshore wind sector has never been more apparent than at present. On the one hand, wind energy and other renewable energy sources are currently generating over a quarter of power consumption across the UK annually, at a price cheaper than gas and nuclear, all while enjoying the highest level of public support. www.peswind.com 13

PES ESSENTIAL At the same time, however, national policy and regulatory backing is at a particularly low ebb, and investor confidence has been dented to such a degree that the pipeline for new development has largely stalled. Recent years have seen the cessation of both the Renewables Obligation (RO) scheme and Contract for Difference (CfD) support for onshore renewables, coupled with the rapid degression of Feed-in-Tariff (FiT) payments for all renewables prior to its phase-out in March 2019. These support mechanisms enabled a staggering build-out of onshore wind capacity equal to nearly 5GW since 2012, with some 2.6GW of new generation installed in 2017 alone. In combination, onshore and offshore wind contributed approximately 45% of the UK’s total renewables capacity, resulting in some 37,400 megawatt hours of annual generation. This is roughly equivalent to the domestic power consumption of 12 million homes, offsetting in the range of 20 million tonnes of CO2 that would otherwise have been produced through conventional power generation. On the face of it, then, the UK’s onshore wind industry should be in a strong position. It has already fulfilled much of its promise, despite the protests of many who never believed the wind sector would be a worthwhile partner in the UK’s energy mix, and there is still plenty of remaining wind capacity to be harnessed if there is sustained support politically and publicly. However, as the current construction boom draws to an end, there are fears that installed wind capacity is at a precipitous cliff-edge. Over the past three years, and ahead of the nose-dive in subsidy support, the decline has been most apparent in the small and medium wind sector, where development has clearly faltered. Enquiries regarding new developments at this scale have rapidly diminished, wind generators are no longer seen as viable opportunities for the economic diversification of landholdings, and it is evident that there14 PES Wind

Developers are also now showing renewed interest in new greenfield development, particularly in Scotland and Wales where, in addition to a more favourable policy environment, the wind resource is often greatest. In particular, there has been a noticeable increase in early-stage site prospecting and resource assessment activity. The developer community is refocusing on new schemes modelled with larger, fewer generators, and, although their increased size risks giving rise to consenting concerns, there is a strong sense that both the devolved governments and public opinion have turned in favour of wind. Corresponding encouragement from the corporate sector, thirsty to purchase green power in their belief, unlike some politicians, that climate change is an existential threat, is resulting in the healthy trading of output from new renewables projects. This can only gain greater ground if the understanding is there that renewable power only gets cheaper over time thereby giving long-term predictability in energy costs. While limited to large-scale development in Scotland and Wales, there are nevertheless grounds for cautious optimism that onshore wind might once more prosper within the UK. Yet this optimism is fragile, and the absence of wider political support risks threatening investor confidence such that other European markets may prove more attractive. But one cannot fault the wind industry for its efforts, and indeed success, in demonstrating that renewable power is the best option for the UK’s energy mix and for protecting the environment and our place within it; the onshore wind industry in particular has proved its resilience and will hope to reap the rewards in the coming years. www.dulas.org.uk16 PES Wind

CMaS was monitoring a 3 MW wind turbine gearbox and alerted remote diagnostics experts about a remarkable change in particle levels. The customer was contacted and endoscopic inspection confirmed that one of the planet wheels was suffering from a bearing defect. The customer was not able to get a crane on site for 8 months, but with remote CMaS monitoring the turbine was kept running at 50% power until the repair was performed. This not only prevented the catastrophic failure of the gearbox, but also the customer was able to run the turbine and continue production while waiting for the crane. Following this, the customer ordered CMaS units for the whole fleet and two other planet wheel bearing failures were detected and repaired while the crane was on site. Up-tower services and upgrades extend the gearbox life while decreasing costs Up-tower repairs can significantly reduce costs and extend the life of wind turbine gearboxes. Moventas continuously develops up-tower repair methods to remedy known failures in most common gearbox types. Standard up-tower repairs include high speed shaft replacements, high speed shaft bearings, and intermediate stage repairs and or replacements and with some gearboxes, helical stage replacements are now also possible. Due to the configurational issues on one gear housing on a Vestas V80 turbine, some weld cracking was observed along with individual material based IMS failures. Gearboxes with these issues used to have to

Let’s be honest: Who actually has everything in use at home that would be technically possible? Often, state-of-the-art solutions are not yet economically viable, and conventional solutions may still be faster or easier to use. Developments in the automotive industry are a good example: where we used to have individual auxiliary systems we now have a wide range of standard support systems. Semi- autonomous driving is already on the rise. Fully autonomous driving has also been feasible for quite some time already, but the market apparently still needs some time to catch on. There are many such examples in the wind industry as well. These include CMS systems, digital planning boards, digital resource management, wind and weather forecasts, the active pushing of error notifications and the use of assistance systems for error analysis and forecasting based on big data.24 PES Wind

PES ESSENTIAL Visionaries take the lead - Maintenance 4.0 What might a vision for the future of maintenance look like? Imagination knows no boundaries. Read our vision of Maintenance 4.0: The entire service plan as well as just-in-time spare parts management are handled fully automatically: the wind turbine autonomously plans its next service visit and reports all required spare parts and consumables directly to the manufacturers. The manufacturer produces the required spare parts just in time using a 3D printer and delivers the products directly to the wind turbine with an electric helicopter. At the same time, if necessary, the service company automatically schedules a visit by properly qualified personnel and informs them of their upcoming deployment using an app. A fully automated warehouse sends the necessary tools using an electric helicopter, which also picks up the technicians from their homes. Invoices and documentation are generated digitally via an interface, which also automatically sends the financial data to the accounting departments of the respective companies.Openness as the basis for changeWhen visionaries present their ideas, inmost cases it is the economically drivenusers who determine whether aninnovation gets a chance. Only when itbecomes clear that introducing a systemwill lead to a productivity increase will ithave real market opportunities.Even though there are already manyprojects in progress, there are also stillmany challenges ahead of us and our entireindustry. This includes simple projects suchas IT interfaces to wind turbines (e.g. OPC)or standardised markings (e.g. RDSPP).Our current activities would not have beenpossible 15 years ago. Similarly,economically viable 10-MW wind turbinesseemed unachievable to all but a fewvisionaries. All stakeholders need to remainopen to change at a very fundamental levelin order for the speed of development tocontinue at this pace.

ASK THE EXPERTS A view from the top André Moura, Founder and CEO of Pro-Drone, Integrated Solutions for the Inspection of Energy Infrastructure, sat down with PES to tell us his perspective on drone inspections and how his company differs from other players in the market. Their experience and strategy means this company is here to stay and remain one step ahead of the game. André Moura38 PES Wind

ASK THE EXPERTS this throughout our development. Firstly, by40 PES Wind complementing or reducing the need for rope access work we can limit the physical hazards workers are exposed to. Secondly, our automated flight system monitors all the structures around the drone and uses them to determine its flight path in real time. This provides an active anti- collision system that prevents the drone from colliding with the blade or tower. With over 350 flight hours and over 1500 blades inspected to date, we are happy to say that our system has been accident free. The last, and most crucial piece of the puzzle is what is done with the data collected. High quality data implies hundreds of high definition images are collected per turbine inspected, resulting in dozens of GB of data and thousands of files at the end of a day’s work. To be able to sieve through them efficiently and extract the significant damage, without missing anything critical, is vital for a manageable and efficient inspection solution. This is the reason why we developed BladeInsight.com, our cloud platform that aggregates, processes and manages all of our clients’ blade data in an intuitive way. It encompasses the surveying logistics, data management, report generation and full data access with an accurate ruler, distance to hub and all the important metadata for a thorough analysis. Our data scientists have implemented several automatic damage statistics and we are looking towards offering automatic damage identification tools over the second semester of 2018. PES: We know that the use of drones is growing rapidly and the technology used is advancing all the time. How do you ensure your equipment remains at peak performance and up to date? AM: That is a very important question and something that has been present in our minds since the very start of the company. Over the past 5 years drones have been coming of age and seen an incredible evolution in availability and reliability, which means that we are only scratching the surface of what they will do for us. However the design and manufacturing of drones is very hard and expensive and it is hard to predict which way the industry will go, which is why our whole philosophy has been to be drone agnostic. Our system comprises several sensors and a computing unit that can be attached to virtually any drone on the market. This means we are able to use the best drone available for the task at hand and to place our system in more modern and competent drones, as they come out. Lastly it also means that we can source the drones locally or even rent out our system

TALKING POINTA look at the statisticsWords: Steve Sawyer, Secretary General at GWEC The Global Wind Energy Council released its annual market statistics on 14 February from Brussels. The 2017 market remained above 50 GW, with Europe, India and the offshore sector having record years. Chinese installations were down slightly – ‘only’ 19.5 GW - but the rest of the world made up for most of that. Steve Sawyer, Secretary General Total installations in 2017 were 52,573 MW, representing a 30% increase in cumulative bringing the global total to 539,581 MW. capacity globally. Offshore is still less than46 PES Wind The annual market was in fact down 3.8% 10% of the global annual market, and on 2016’s 54,642 MW; and the cumulative represents only about 3.5% of cumulative total is up 11% over 2016’s year-end total of installed capacity, but it’s growing quickly. 487,657 MW.

Offshore will become an increasingly important part of the future Chinese market and will soon start to vie for the number one spot in terms of offshore installations. However, it will be quite some time, if ever, before China begins to challenge Europe as a whole. India had a record year, installing over 4 GW, but will be the ‘victim’ of a policy gap in 2018. If all goes according to plan, however, installations under the new auction system going forward will exceed 5 GW/year in order to meet the country’s target of 60 GW of wind by the end of 2022, from a year end 2017 total of ~33 GW. Pakistan, Thailand and Vietnam all continue to show promise, and there are stirrings in the laggard markets in Japan and South Korea; particularly in South Korea as a result of policies being enacted by the new government. www.peswind.com 47

TALKING POINT The US had another strong year with 7.1 GW and has a very strong pipeline for the next few years. Despite the political turmoil, the US industry seems to be in a solid position, having narrowly survived a scrape with Congress, and looks to be stable going forward through 2020, although there is still some uncertainty about what happens after that. There were no new offshore installations in the US 2017, but there are ambitious plans at the state level up and down the East Coast, and great interest from European manufacturers, developers and investors in this potentially huge new market segment. Canada saw a substantial dip in 2017, but new developments in Alberta will help in the coming years, and Mexico is still poised to become a major market, with expectations for a 1,000 MW market in 2018, rapidly increasing thereafter to meet the industry’s expectations of 12 GW (up from 4 GW at 2017 year-end) by 2022 or thereabouts. In Latin America, Brazil chalked up more than 2 GW, despite political and economic crises which are not yet fully resolved. Uruguay completed its build-out and is nearing the 100% renewable energy target in the power sector, with somewhere between 35 and 40% of its demand being fulfilled by wind. The results of 2016 and 2017’s auctions in Argentina will start to show up in strong installation numbers in 2018 and beyond. There was a lot of activity in Africa and the Middle East, but the only completed projects were in South Africa, where 621 MW of new capacity was added to the grid. The good news in South Africa is that after a delay of about 2 years, it’s very successful procurement programme is moving forward again under its new President, and wind and other renewables will play an increasing role in South Africa’s energy future.

TALKING POINT The dramatic price drops for wind technology has put a big squeeze on profits up and down the whole supply chain, but the industry is seeking to make good on its promise to provide the largest quantity of carbon-free electricity at the lowest price. Smaller profit margins are a small price to pay for leading the energy revolution. As New Energy Finance founder Michael Liebreich puts it, we’re well on our way past the first tipping point (where wind is cheaper than incumbent for new-build), and we’re on the edge of the second, where new-build wind (and soon solar) will be cheaper than operating existing incumbent generation. We’re winning the war, although not yet fast enough to play our part in meeting the climate targets in the Paris Agreement. But we’ve laid the foundations, and now with decent frameworks and a little bit of policy support (price on carbon, anyone?) we’ll get there; hopefully in time to save the climate. The next round of climate talks will seek to increase the ambition in the national pledges, hopefully putting them in the range of the reductions required to meet the targets. For the first time since this issue emerged at the end of the 1980s, we can actually say that ‘we have the technology’…or most of it. The only remaining question is whether or not we will have the wisdom to use it and use it in time. www.gwec.net50 PES Wind
