Power & Energy Solutions

The premier renewable energy publication

As market demand for wind turbines has grown, so too have the demands for quality and performance, in order to reduce the levelized cost of energy (LCoE) and demonstrate that the technology is not just a clean solution for electric power generation, it is also a profitable addition to the energy mix. This is especially the case for critical components such as power converters because the performance of the whole turbine depends on them. The response is focused on increasing the reliability and durability of these components, making wind turbines more economically viable assets. High quality design and extended validation methods of power converters are key to guaranteeing the reliability and durability of the turbines in wind farms facing the toughest operating conditions. Ingeteam’s new-generation power converters have been validated using the toughest test scenarios and most realistic configurations, to prove in advance that the converter will be properly integrated within the turbine and operate correctly under the most demanding situations. The market demands continuous performance improvement and regulatory innovations take this factor into account. Ingeteam participates in the committees which issue these requirements and integrates the latest regulatory developments at the design phase of the company’s new generation power

The smart factory is a term we all know well and is used in reference to the implementation of Industry 4.0 in the manufacturing environment. Significant benefits such as improved quality, higher productivity and cost reductions have transformed industries such as automotive and electronics in recent years through implementation of smart connected assembly solutions. Wind energy is catching up. We now see the use of smart tooling with inbuilt intelligence for critical assembly in factories for nacelle and gearbox production, but what happens on work sites out in the field? There is a significant amount of critical bolting operations take place in construction, commissioning and maintenance which have a direct impact on the turbine performance, reliability and cost. However, the reality is that in many cases conventional bolting methods are still being used in the field due to old processes remaining in place, outdated tool fleets, and a general lack of awareness exactly how smart factory thinking can really be applied in the field with the technology and solutions available on the market today. The energy transition is happening, but the wind sector must drive a transformation in critical bolting across the full value chain to truly benefit from the possibilities

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%

The declaration of a climate emergency in Scotland, quickly followed by the rest of the UK, has been a boon for the renewable energy sector. After all, without clean power, heat and transport fuels, our ambitious net-zero targets are totally out of reach. But we know tackling the carbon emissions caused by our increasing demand for energy isn’t enough on its own. The world’s raw resources are limited. As demand for these resources increase, supplies deplete, driving up costs. It’s imperative that we change the way we use products and materials, and Scotland’s ambition for a circular economy shows we are committed to making that change. The circular economy represents an opportunity to move away from the linear approach of creating and delivering a product or service that is disposed of at the end of its life. This waste represents an enormous pool of resources that can be exploited with minimal impact on the environment. A circular economy focuses on responsible production: businesses which supply products and services get the maximum life and value from the resources used to make them, keeping these resources in a continuous loop of re-use. Doing that can take a number of forms: • from re-use and repair -where a product’s

By 2040, it is expected that around 4GW of the UK’s onshore wind capacity will be repowered projects. The next few years will see slow growth in this sector, around 100MW per year from 2020, but increasing to around 500MW per year by 2035. So as a significant number of wind turbines begin to reach the end of their original planned life service, our attention is focussed on the topic of life management strategies to support owners make smart business decisions about the next phase of their wind farms. The decision on life extension is complex and inevitably includes technical, economic and legal considerations as well as acknowledging uncertain future electricity market prices and revenue streams, which determine if life extension is economically feasible. Decommissioning, repowering or continued operation are the main options to be considered and although wind turbines are generally designed for a service life of 20 years, many can continue to operate past their original design life. As the size and capacity of turbines increase, and technology continues to improve, the economic case for life extension is likely to become clearer. In fact, the lifetime of a wind turbine can often be extended by minor and low-cost

It is not an understatement to say that 2020 has been one of the most turbulent years in recent history, with the Covid-19 pandemic leading to seismic shifts in industries the world-over. But despite significant supply chain disruption, the renewables industry has remained remarkably resilient compared to conventional power and wider infrastructure asset classes. A growing variety of investors have subsequently entered the space, expecting to grab a slice of the pie and reap the dual benefits of non-correlated returns and greener credentials. But the renewable energy market is not so black and white. Broader trends at play in the space are generating new investor needs, and renewables owners must adapt their offerings to meet these accordingly. Indeed, the renewables market has been undergoing a shift of its own amid the phase out of state-backed subsidies, with portfolios growing more diverse and owners adopting more merchant-led approaches. This has raised several new challenges in the industry as projects have become increasingly exposed to volatile power prices. Whilst the renewables sector has continued to perform strongly during the pandemic, the coronavirus has brought these new market risks to the fore, and developers and renewables project owners now need to provide investors with confidence around the
