Proper blade maintenance for optimal turbine performance

Blades have been the so-called ‘underdog’ in wind energy for a long time. Its use was practical but not seen by definition as a vital element. Only later did the industry became aware of its importance in the energy production of a wind turbine. Dutch blade inspection and repair specialist Redak has witnessed this process…

Rabobank Project Finance on financing wind projects in rapidly changing times

When the first offshore wind farm was built in Dutch waters, no one at that time would have been able to foresee how quickly the price per megawatt hour would drop. Neither did the Rabobank. A conversation with Marc Schmitz and Pieter Plantinga, managing director and executive director respectively at Rabobank’s project finance department, responsible…

Long read: Developing wind onshore is an organic process

In 1995, Dutch entrepreneur Alfons Wispels founded Raedthuys to develop onshore wind energy. What started with a single turbine on a farmer’s grounds in Zeewolde, Flevoland, developed overtime into a mature company that currently owns and operates 70 wind turbines located all over the country, has another 60 granted and now also develops solar energy.…

Safe upscaling of wind turbines

Boltlife’s blade to hub flange connection methodology Wind turbine generators get bigger and bigger each year. As a result, the dynamic forces on a rotor blade during its operation become immense. These tremendous forces are transferred through the blade-to-hub connection, which makes it imperative that this connection doesn’t have any weak points. This poses challenges…

Long read: Citizen participation in the energy transition

The Netherlands, albeit with a delay, is taking steps in the energy transition. Wind, both onshore and offshore, is a large driver in the transition and many gigawatts of it will be needed. Especially onshore, social acceptance is vital in ensuring that these megawatts will be realised. So vital that local participation has been included as a requirement in…

Wind farm in focus: De Veenwieken Wind Farm

In the eastern part of the Netherlands, between Ommen, Hardenberg en Dedemsvaart, where till recently green pastures dominated the view, ten Enercon wind turbines are slowly rising on the horizon. All in close cooperation with the local citizens. On 7 September, this onshore wind farm De Veenwieken, opened the construction site to the public. De…

The sun is not going to make the difference, offshore wind is

To bring the energy transition to a success, Europe will have to invest in wind energy. A significant part of that wind energy will have to come from offshore wind turbines. Numerous countries in Europe are currently working on the installation of ever larger offshore wind farms. But to be able to build those wind…

HSM Offshore: Building the heart of an offshore wind farm

In 2002, HSM Offshore built the offshore substation for the first offshore wind farm, the Danish Horns Rev 1. Almost 17 years and several wind farm generations later, the Dutch manufacturing company is still building offshore platforms for the wind energy industry. The latest being the Borssele Alpha and Beta platforms. You won the contracts…

Stepping up to serve the future grid

Future grid capacity is currently a hot topic in the Netherlands. With the wind projects becoming larger, especially at sea, what are the requirements in terms of cable designs? Wind Energy Magazine spoke to Mario Loi and Hans Schwirtz at the Delft production facility and head office for the Nordics of international energy and telecom…
