Salamanca cabinets, which are giant batteries and responses against blackout

The “zero energy” that shook the entire country and Portugal this week established the electrical ecosystem. While the main unknown is solved, the problem that arose in historical blackout, there are many diagnoses on the health of the system that provides us with electricity, its main weaknesses and its power points. Among these, one of them appears above all: pumping or reflective aquatic factories, which have a wonderful example that is already a mature technique capable of repeating its production.

Among all the generation technologies that contribute to the production of Spanish electricity, the photo plant is one of the most classic and valuable. Its role in restarting the system on Monday afternoon was decisive. As the procedures were also distinguished, the replacement mechanism has been activated, a type of protocol to restart the system, as the electrical celebrations were a key. The great fire test resulted in successfully.

Companies in this sector, under Red Electrica orders in this case, first activated many technologies; Among them, all electrical plants and cycle plants combined, which burn gas. And this type of generation centers emerged above all: photovoltaic pumping factories.

These plants work in full performance in less than three minutes, which are those that can produce energy more quickly for their difference in the system and are able to bring the amount that was produced to the defendant, the first thing to do to restore the offer. Among them are two in Salalamca and Zamora are cut off for the first entry into the operation, namely aldeadávila and Ricobayo.

The electrical pumping of pumping or reflected plants has a storage capacity between its great characteristics, which is one of the weaknesses in the Spanish system, and the lack of preparation for storing electricity and using it at the will to manage the system. They are original hydroelectric batteries and true protection of the electrical system.

The photovoltaic pumping technology allows you to store large energy on a large scale and is in full development. According to Iberdrola, the owner of Aldeadávila, is more profitable and provides stability, safety and sustainability for the electrical system, by generating a large amount of energy with a very fast response time with much higher performance than the best batteries.

These giant batteries can work when there is an excessive request. Its main task is to store water in the moments of demand less and benefit from it to generate energy in larger consumption hours. How do they work? Electricity is used to raise water to the upper dam. When the generation takes it, they drop it.

This is what he did on Monday night. Aldeadávila was born immediately in a large amount. When a blackout came, he was connected to the system and fell to “0”, but from 3 pm he started producing electricity strongly to 341.68 MW; This practically remained twelve hours, including in the afternoon, night and early.

These central networks and good networks that Salamanca enjoys The first Castilla YEón Province And one of the first in Spain.

Production record

These types of plants are the technique of the moment and have increased their production significantly in the Duero system, as it is a large part of the facilities that are already opposite.

In 2024, the hydro in 2024 witnessed a significant increase in its contribution to the electricity generation mix in Spain, with a larger year of pumping since its construction. If we compare it with the annual historical average, the past 2024 exercise is more than twice, specifically, 2.3 times more.

Aldeadávila is one of the basic pieces of energy storage, which only enjoys in Iberola Centrals with more than 4400 MW installed by pumping electrical plants. Electrical plants such as Villarino and Adidavilla (Salammana), Jouvis in the Timaga River (Portugal) or the Cortis La Moeel Complex (Valencia), the largest composition of these characteristics in Europe, has these characteristics.

In Castilla Y León, the center of De Villarino, in the Mandara Dam, is of vital importance with 810 megawatts of reverse installed energy. Thus, renewable and clean hydraulic energy is created to supply more than half a million homes.

This slope uses 400 scales between Almendra’s tanks, the third largest in Spain, and Aldeadávila, both of which are located in the province of Salamana.

More reflected vehicles

In recent years, electrical storage technology is considered as a key to the system of renewable energy resources growth. In this sense, it is necessary to locate a new facilities using the current infrastructure and at the same time seeking to provide greater flexibility in the process.

Ibrdrola activated the full operation of the pumping capacity of one of the opposite groups of the electrical power plant in Zamoraana in Valparaíso. Thanks to the distinguished work of his technical team, he was able to add 90 megawatts (MW) to the storage capacity to pump the Spanish system; He added the last pumping in Group 2, an additional 60 megawatts of pumping capacity in the Tira River.

Improving the accumulation center by pumping Santiago Sil -xares, in the municipality of Vilamartín de Valdeorras, ourense, in full performance. To do this, a fixed start that enables the current 5mWh battery to be attached to both the starch of the network, which contains 230 meters, 50 megawatts of energy and the capacity of approximately 3 GB (3000 megawatts).

The pumping project in Valdecañas (Cáces), which is already in the process of implementation, will improve the power capabilities of the Tajo River by storing the surplus power in the Valdecañas reservoir.

It will have a total capacity of 275 megawatts and includes an attack battery system with groups. The battery capacity is 15 megawatts, and if it is fully charged, it can reach 7.5 megawatts of stored energy. The battery group and hydraulic groups have a 210 GWH power reserve (equivalent to 5.2 million electric car batteries).
