Extreme rainfall and severe weather: events in Sardinia have quintupled in 35 years
There was a time when two or three extreme storms per year were considered normal. Today, in some areas of the island, more than ten are recorded annually. These storms are short but extremely intense, capable of putting significant pressure on waterways, slopes, and drainage systems, often concentrated within just a few kilometers and unfolding in a matter of minutes.
This trend is highlighted by an international study published in Natural Hazards and Earth System Sciences, led by the University of Milan, with contributions from the Institute of Atmospheric Sciences and Climate of the National Research Council and Ricerca sul Sistema Energetico. By analyzing the period 1986–2022 through a new high-resolution meteorological dataset, researchers identified a significant increase in extreme events, particularly during summer and autumn, with clear impacts also observed in Sardinia.
Severe weather in Sardinia: what it means for the wind sector
Recent waves of severe weather affecting Sardinia have brought the resilience of energy infrastructure back into focus. Strong gusts, sudden precipitation, and extreme weather conditions put not only the territory under stress, but also renewable energy generation assets.
In the case of wind power, highly adverse conditions can result in:
- Increased turbulence
- Gusts exceeding nominal limits
- Structural stress on tower, nacelle, and blades
- Automatic shutdown once cut-out wind speed is reached (the maximum wind speed at which a wind turbine can safely operate before stopping automatically)
And it is precisely in these moments that turbine quality is truly tested.
Reliable performance even under extreme conditions
In recent days, the 100+ Northern Power Systems wind turbines installed in Sardinia have continued to operate steadily and efficiently up to the cut-out wind speed, fully complying with safety parameters.
This translates into:
- Consistent energy production as long as conditions allow
- Activation of protection systems only when necessary
- Preservation of the plant’s structural integrity
This is no coincidence, but the result of an engineering approach focused on maximum reliability.
Hurricane-proof wind turbines: engineered to withstand extreme events
Northern Power Systems turbines are designed to be hurricane-proof, meaning they are suitable for operation even in regions exposed to extreme weather events.
Not surprisingly, the NPS 100 wind turbines are also installed in the Caribbean, a location well known for hurricanes and tropical storms. This design philosophy results in reinforced structures, advanced control systems, automatic protection strategies in case of extreme winds, , high-safety & quality standards and product certifications.
At a time when climate change is making severe weather events increasingly frequent, having wind turbines capable of withstanding intense gusts and extreme conditions represents a decisive competitive advantage and peace of mind for owners and investors.
Energy resilience and climate change
The study published in Natural Hazards and Earth System Sciences highlights how the increase in extreme events is a key factor in planning future infrastructure. Resilience is no longer just about civil protection, but also about ensuring continuity in renewable energy generation.
In Sardinia, a strategic region for wind energy development, the ability to keep systems operational even during adverse weather conditions means:
- Greater grid stability
- Reduced outages
- Optimized return on investment
- A tangible contribution to the energy transition
Conclusion: quality proven in the field
The recent severe weather in Sardinia is not just a meteorological event. It is a real-world stress test for energy infrastructure.
The performance recorded by Northern Power Systems wind turbines confirms a fundamental point: engineering quality, safety and certification makes the difference. Continuing to generate energy up to the cut-out threshold, even under highly adverse conditions, is concrete proof of a reliable, efficient system designed to endure.
In an evolving climate scenario, choosing hurricane-proof wind turbines is not just a technical decision.
It is a strategic one.
