Nordex: the recipe for a miraculous recovery

When, at the end of 2022, all Western turbine manufacturers were suffering million-euros losses and publishing plans to emerge from the crisis, few would have bet on the smallest OEM and, in theory, the one in the most delicate position: Nordex.…

+800W and 25% efficiency solar panels?

When visiting a solar fair, one of the things that catches your eye is the race to announce the most powerful panel. The evolution of commercial panel power has been spectacular: in just over three years, we have gone from 400W panels to the…

Have we reached renewable saturation level?

 “Captured prices", "cannibalisation", "economic curtailment", "renewable saturation"... these are concepts that we have been hearing about renewables for some time now, but which have multiplied since the blackout, monopolising a large part…

Conclusions after the big blackout: we need grid-forming batteries

The 12:33h of last April 28th has already gone down in national history as the moment when 11 GW were disconnected and caused the largest blackout ever suffered in Spain. 48 hours later, the root cause of the disconnection is still unknown,…

What does 2025 look like for wind manufacturers?

While the Windeurope 2025 trade fair is being held in Copenhagen, it is a good time to take a look at the current situation and the near future of the main wind power manufacturers. It has to be said that the trade war unleashed from the USA…

What is Agrivoltaics?

Many critics of the current development of solar photovoltaic focus their arguments on the amount of land required for this technology. And not only because of the land occupation but also because of the impossibility of using this land for…

Windturbine observer’s guide

When I pass by a wind farm, I can't help but try to distinguish the manufacturer and model of wind turbine. And I think I'm not the only one, so this article is intended to help you to be able to identify at a glance the different wind turbines…

Wind and Solar in Spain – Overview 2024

Seventh edition of the summary of renewables in Spain, with a review of the main data summarising a year 2024 marked by the growth of solar energy, the stagnation of wind energy and fears in the sector of price cannibalisation.   The…

Revisiting wind turbine test centres

Four years ago, we dedicated an article in this blog to the wind industry's testing and validation centres where we marvelled at the facilities prepared for what, at that time, were the offshore giants: models of up to 12 MW with blades of more…

Would it make sense to design wind projects based on the price of energy?

Traditionally, the goal of wind farm design is to maximise annual energy production (AEP) within the safety margins of the turbine. But today, with electricity prices differing depending on the time of day, it may make more sense to maximise…
