The SERTO connecting nut, marked with code number K 87163, is a precision-engineered fitting used to securely join fuel piping in the ZV40/48 engine’s fuel delivery system. Manufactured to tight tolerances, this nut ensures leak-free connections even under high pressure, preserving the integrity of the fuel line and minimizing fire risk. Its compatibility with SERTO’s compression fitting system allows for quick installation and reliable sealing. A critical component in maintaining fuel system efficiency, the connecting nut supports safe, continuous engine operation in demanding environments.
The thermometer labeled with code K 92023 plays a crucial role in monitoring engine health by measuring the temperature of both cooling water and lubricating oil in the ZV40/48 diesel engine. Accurate temperature readings are essential for preventing overheating, oil degradation, and mechanical stress. Designed for durability and precision, this thermometer provides real-time feedback to operators and maintenance crews, enabling early detection of abnormal conditions. Its robust construction ensures reliability even in the harsh thermal environment of marine and industrial engine applications.
The double initiator with code number K 84467 is a specialized monitoring device used in the ZV40/48 diesel engine to visually confirm the presence and direction of fluid flow. Installed in key lubrication or cooling circuits, this component helps operators detect disruptions or blockages in real time. Its transparent housing or flow indicators provide immediate visual feedback, enhancing maintenance efficiency and operational safety. With dual input/output functionality, the double initiator supports more precise diagnostics and is essential for ensuring optimal flow conditions in critical engine systems.
Why mitigation is no longer enough – it's time for systemic resilience

Spain and Portugal seek the cause – but society seeks a solution
After nearly 60 million people were left without electricity in the historic blackout of April 28, 2025, Spanish Prime Minister Pedro Sánchez stated that the two main priorities are:
Beyond technical error: Societal vulnerability in a power outage
In just a few hours, there were:
Mitigation helps – but it’s not enough
Emergency response, backup generators, and aid from France and Morocco helped to soften the blow. But the question remains:
Why didn’t key nodes have their own resilience sources?
Why doesn’t every hospital, airport, data center, and civil protection HQ have a microgrid with battery backup + emergency diesel generator?
Solutions exist – but haven’t been implemented
Adriadiesel already offers systems that:
Political will must match technical availability
While governments focus on the cause, the industry must shift focus to resilience.
Power outages are not a question of if, but when – and every city and institution must have:

Mitigating the Grid Collapse on the Iberian Peninsula – and Why This Must Become Standard

A system collapse — but not for everyone
When the Iberian power grid collapsed in seconds on April 28, 2025, life came to a standstill. But not everywhere.
According to AENA, the Spanish airport authority, backup systems enabled terminals to keep operating even amid the worst energy crisis in the region’s history.
And they weren’t alone:
— in many cases remained operational thanks to local microgrids and battery systems, supported by emergency diesel generators.
What saved us — and why isn't it everywhere?
Batteries and microgrids are no longer “extras” — they are core security infrastructure for a world where:
How much would it actually cost to avoid darkness next time?
For less than 10% of the damage caused by the collapse, we could deploy:
Comparison:
Damage in Spain alone: €1.6 billion
Cost to install 1,000 battery-backed microgrids: < €1 billion
From reaction to resilience
Instead of reacting after the fact, it’s time for a new logic:

Conclusion: Every community needs a Plan B — and that’s a microgrid
The Iberian collapse showed who was prepared and who wasn’t.
Next time, that difference may go beyond interrupted services — it may mean lives, health, and national security.

Is €1.6 billion enough to prevent a grid collapse?
How much did the Iberian blackout really cost – and what could have been done with that money?

€1.6 billion – the cost of inaction
In April 2025, the Iberian Peninsula experienced a historic power grid collapse. Millions in Spain and Portugal were left without electricity.
According to Spain’s leading business association (CEOE), the damages amounted to at least €1.6 billion – in Spain alone.
Other sources, like RBC Capital, estimate the cost at €2.25 to €4.5 billion, making this the most expensive energy incident in European history.
But the key question is: Could it have been avoided?
And if yes – what could €1.6 billion have achieved?
What could have been done with €1.6 billion?
Grid collapses are rare – but not random. They usually result from:
With €1.6 billion, we could have built:
| Battery Strategy | Capacity | Estimated Cost (€) | Coverage |
| Regional battery hubs (10x) | 50 MWh x 10 | ~€150 million | Cities with >200,000 residents |
| National grid stabilization | 500 MWh | ~€600–750 million | Full frequency and voltage support |
| Distributed black-start units | 100 locations | ~€300 million | Restart capability across Iberia |
| Surplus for upgrades and control | — | ~€400–500 million | Battery replacement, EMS, control systems |
Total cost: ~€1.5 billion – less than a single collapse.
Not just protection – but a return on investment
Battery systems don’t just protect – they:
How did we get here? A gap in EU grid strategy
The EU plans to invest €584 billion in grid upgrades by 2030 (European Commission).
Yet the Iberian incident shows:
Spain and Portugal are energy leaders – but even the most advanced grids are vulnerable without proper battery deployment.
Adriadiesel’s solution: Modular, fast, scalable
Adriadiesel is developing containerized battery systems using second-life EV batteries:
These systems could have mitigated or entirely prevented the Iberian collapse – and they are available today.
Conclusion: Pay now – or pay more later
€1.6 billion can either be written off as a loss, or invested to ensure it never happens again.
The technology exists.
The economics work.
All that’s missing is a strategy shift – from reactive to resilient.
