Words: K. Adriaenssen, W. Smook, J. Peeters A revolution is happening in the world of renewable energy. All key markets have adopted auction-based approaches to subsidising renewables. New wind market dynamics In theory, the idea is rather simple. Set a target level of investment in renewable energy capacity, and then allocate contracts to the lowest bidders. As renewable energy markets mature and penetration increases, a growing number of countries are looking to reduce subsidy costs by spurring competition. This concept will initiate large disruptions as markets evolve to a new equilibrium. Looking at how procurement costs are falling in countries that had previously relied on other mechanisms, it seems possible – even likely – that auction-based procurement is accelerating price erosion and reducing procurement costs relative to what we would have seen otherwise. This sounds like good news. But is it really? It’s good news if falling procurement costs reflect the market’s ability to seek out the most cost-effective projects, and if this competitive pressure will fuel efficient innovation going forward. But there are concerns about whether the industry can cope with the developments and cost reductions going forward. The success of these dynamic market conditions will depend on an understanding of how auctions can be

Words: Leonardo Gómez, Engineering Manager at TSR Wind PES is excited to introduce TSR, a small Spanish engineering company that has developed technology through R&D, to provide affordable services that can compete in price, with traditional methods in the wind energy sector, solving problems that historically, would have involved risks, non-competitive stopping times and an increase in operating personnel. With the growing number of wind turbines soon to be operating out of warranty, more frequent, minimal risk, effective and affordable services are a necessity in the industry. Maintenance often conflicts with tight budgets and down times but at the same time, high performance rates are expected from the windfarms, where one of the more critical factors is the inspection and repairing of the blades TSR conceived its magnetic coupling robots for wind turbine maintenance, as a solution to minimise cost, reduce risks and obtain better results. The development started with the idea of a climbing, cleaning robot and has evolved into a series of different models of robots, according to the service it provides. The first ones on offer to the public were the EOLOS series, a type of robot specifically designed for blade inspections. TSR entered the international market with the robotic

While performing service and maintenance on wind energy plants, employees routinely work at great heights. Fall protection is therefore a requirement for them. They use climbing protection equipment when climbing the towers. When it comes to work safety, leading manufacturers are increasingly involving users in the development of new solutions. Collaboration between Siemens Gamesa, the manufacturer SKYLOTEC, and the supplier ICM Safety shows how this works successfully. The ’Claw’ cable runner for steel ropes is a solution that simplifies use and reduces the risk of accident. With around 27,000 employees on five continents, Siemens Gamesa is one of the leading providers in the renewable energy industry. The company provides service and maintenance for 23,000 turbines around the world. They monitor more than 3,000 onshore and offshore facilities in Great Britain and Ireland alone. Fall protection is required for employees while they perform service and maintenance work on wind power systems. This does not just apply to when they are working high up, on the turbine. In many cases, Siemens Gamesa employees reach the turbine by means of a climbing protection system that is installed within the tower. This consists of a rigid anchor line, such as a steel rope or rail and

We have said this before but how much lighter and more efficient can these heavy lift jack-up vessels get? PES brings you SOUL, the 4th generation of wind turbine installation vessels. After successfully launching their revolutionary heavy lift jack-up vessel design, SOUL-partners, SeaOwls and Ulstein, continued their mission to develop the optimal range of heavy lift jack-up vessels that will enable the offshore wind industry to bring down the cost of renewable energy. Different from the existing third generation fleet of wind turbine installation vessels (WTIVs), the SOUL heavy lift jack-up vessel design was conceived with the actual lifting operation from a stable-up platform, in mind. This design focus resulted in an unmatched heavy lift performance in terms of lifted load, reach and height for a jack-up vessel, when used for either afloat or firmly standing on its four legs. Existing WTIVs are either ‘ships with legs’ or ‘self-propelled jack-up barges’ and both design concepts have their own strengths and weaknesses. Legged ships have limited payload and lifting capacities due to their heavy structures and narrow gaps between portside and starboard legs. Jack-up barges, with propulsion, have their own sailing and seakeeping challenges. SOUL - the fourth generation of wind turbine installation vessels The SOUL

Words: Jenny Hogan, Deputy Chief Executive, Scottish Renewables The UK has more offshore wind turbines than any other country in the world. But while Scotland has 25% of the whole European wind resource, only around 5% of the UK’s offshore wind fleet is currently north of the border. Finally, however, that is starting to change. Record-low prices in September’s Contracts for Difference saw EDPR’s Moray East project succeed where it had previously lost out. This scheme will now join SSE’s Beatrice in the stormy seas off our North East coast. It isn’t just the wind farms themselves which are happening in Scotland, either. Two events in coming months – a Floating Offshore Wind Conference on November 14 and Scottish Renewables’ Offshore Wind Conference on January 29-30 – will allow a burgeoning supply chain to share ideas with developers and decision-makers. Both come at a key time for the sector, with policy optimism still buoying up offshore wind following the largely-positive Clean Growth Strategy and secondly, the CfD auction results. The results of this auction were good news for Scotland, for our environment and for our energy system. The cost reductions in offshore wind have been dramatic and are testament to the determination of developers to drive down costs

PES is pleased to share this practical advice on saving time and money, in getting approval for wind farm projects, from Al Maiorino, the President of Public Strategy Group, Inc.,. This is based on his years of experience in successful and varied campaigns throughout the USA and abroad. Renewable project companies have moved light years in the past decade on their ability to educate residents on the benefits of renewable projects. However, there is more work to be done to ensure that wind and other renewable projects do not get entangled in a web of misinformation, and eventually delayed or even defeated. All too often, companies find that every single month a project is delayed, the renewable company loses thousands of dollars. Even a delay of a few weeks is costly, so keeping with a strict entitlement calendar is essential. This month, one such project blocked by the Scottish government was West Coast Energy’s Highland Perthshire wind proposal. The wind farm was in the pipelines for five years and had been scaled back from forty to twenty-five turbines in response to public outcry. The project would have been able to generate enough clean energy to power 40,000 homes and start a community
