Summary of a Possible Technical Cause of the Grid Collapse
According to Croatian physicist Dr. Ivica Aviani, the possible cause of the power grid collapse on the Iberian Peninsula was not an atmospheric phenomenon, but a loss of synchronization among generators within the grid. The electrical system depends on perfect alignment of frequency and phase of all generators—if even a slight difference occurs, the grid attempts to "correct" it, potentially leading to exponential amplification of oscillations.
Dr. Aviani compares this behavior to microphone feedback: when a microphone picks up noise from a speaker and sends it back to the amplifier, it creates a loop that increasingly amplifies the noise—until the system collapses. In the grid, a similar effect can arise from a small phase or voltage impulse difference, leading on a large scale to a cascading reaction and the breakdown of the common grid "shaft."
Darkness in the Iberian Peninsula: What the Grid Collapse Taught Us
The recent energy collapse that hit Spain and Portugal exposed serious weaknesses in Europe's power grid. The synchronized operation of generators, which forms the basis of a stable grid, was disrupted—likely due to a technical disturbance that triggered a cascading positive feedback reaction.
The question arises: How can Europe protect itself from such disturbances in the future?
Regardless of the Possible Source of Failure, One Possible Answer Lies in Containers with Used Batteries
Adriadiesel is developing a modular battery power plant in a container format, using "second-life" batteries from electric vehicles. These systems are not only environmentally sustainable—they are also a key tool for grid stabilization.
How Does It Work?
Advanced inverters can operate in so-called grid-forming mode (where the inverter defines voltage and frequency instead of just following them), actively stabilizing the grid and enabling operation even in the event of a main source outage, provided there is sufficient capacity and proper coordination with other sources.
An excessive share of renewable systems without advanced inverters capable of generating artificial inertia and reactive power leads to:
Furthermore, due to the constant development of new technologies, it is highly likely that any power system in the future will continue to use a set of various inverter technologies simultaneously. Most likely, the problem of inverter technology diversity will not disappear; it will only get worse.
What Does Adriadiesel Offer?
Practical Application
In a case like the one that occurred in the Iberian Peninsula, 50 to 100 Adriadiesel containers deployed around key hubs (Madrid, Barcelona, Lisbon) could:
Sustainability and Economy
These systems:
Important Regardless of the Actual Cause of the Outage
What happened now in Spain and Portugal can happen to any power system.
Regardless of the actual cause of the power grid outage/instability, sufficiently large battery energy storage systems can react quickly and powerfully enough to stabilize the power grid in real time and later quickly restore the grid for uninterrupted operation.
Because ready technical solutions exist, we urge power grid operators to urgently plan and implement the necessary backup safety systems like battery energy storage without delay.
The Future Lies in Decentralized Stability
As Europe transitions to renewable sources, it loses the natural stability offered by fossil fuel power plants. Containerized battery systems, like those developed by Adriadiesel, are key to energy security and resilience.
It's time for car batteries to get a second life—in the service of the stability of entire nations.

The pressure connection, designated by code number H 87603, is an essential interface point in the fluid or gas distribution system of the ASL25 diesel engine. This component enables the secure transfer of pressurized media—such as oil, fuel, or air—between different parts of the engine or connected systems. Its robust construction is designed to endure high pressure and temperature conditions, ensuring leak-free performance and maintaining system integrity. The precision engineering behind the pressure connection supports reliable engine functionality and safety in demanding operational environments.
The component referred to as “Blunt,” with code number H 74127, serves a specialized role within the ASL25 diesel engine. Though modest in size and appearance, this element may function as a physical stop, alignment tool, or load distribution element, depending on its specific application within the engine assembly. Engineered for strength and resilience, the blunt component ensures stability and positional accuracy of other parts, especially under high vibration or load. Its importance is often recognized in preventing misalignment or damage in high-performance engine operations.
The pump cover, identified by code number N73117, is a critical protective and structural component of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ASL25 diesel engine. Designed to encase the pump mechanism, it prevents contamination and ensures the integrity of the internal components against external elements such as dust, moisture, and mechanical impact. Crafted from durable materials to withstand thermal and mechanical stresses, the pump cover plays a vital role in maintaining pump performance, reducing wear, and facilitating maintenance access. Its precision fit contributes significantly to the operational reliability and longevity of the entire pump system.
Balancing the electrical grid in unexpected situations
A power plant using containers with second-life EV batteries could have helped avoid today's power outages in Spain and Portugal by:

Note:
The spacer sleeve, with code number H 33032, serves as a crucial element in achieving the correct axial distance between components within the ASL25 diesel engine. By providing precise spacing, it ensures proper alignment and distribution of mechanical loads, thereby enhancing the stability and durability of the engine structure. Made from robust materials, the spacer sleeve resists deformation and wear under operational stress. Its accurate design and fit are essential for maintaining the mechanical integrity and smooth operation of the engine over time.
