After Blackout in Spain: How safe is Sachsen's power grid really?

Spanien, Land - On April 29, 2025, Spain, Portugal and parts of France experienced a massive power failure, the causes of which have so far been unclear. The Spanish power grid recorded a sudden loss of 15 gigawatt generation capacity at 12:33 p.m., which corresponded to 60 percent of the nationwide consumption. Such massive fluctuations in the power supply are particularly questionable, since the European infrastructure is not designed for such high losses as the spokesman for the National Energy System Design program of the Helmholtz Community, Veit Hagenmeyer, emphasized. Experts from Red Eléctrica Española (REE) also expressed that the first disorder was overcome, but the system could not cope with the second incident, which led to the far -reaching blackout. Ultimately, the solar power generation faded drastically from 19 to 5 gigawatts shortly before the incident, which is considered a possible cause of the problem, but haunting examinations are still ongoing. lvz

In Germany, the situation and possible risks are analyzed very precisely. The Saxon Ministry of Economic Affairs referred to the Federal Network Agency, which is responsible for monitoring the country's network operators. Klaus Müller, President of the Federal Network Agency, said that a similar incident as in Spain was "very unlikely" in Germany. The German power grid is redundantly designed, which means that a different one can step in if a line fails. In addition, there are several security systems in Germany that enable the network to restore. The CEO of Sachsen-Energie AG, Frank Brinkmann, added that the stability of the German networks is above average, however, he warned that the feed-in of solar power in certain regions can lead to heavy load and thus need additional investments in network expansion.

cause research and international networking

The Spanish power grid has limited international networking, which was identified as a weak point by specialist Miguel de Simón Martín. With only three percent of the installed capacity, which is in exchange with Europe, critical network loads are difficult to compensate for. An investigation committee has been set up to clarify the exact causes of the incident. Prime Minister Pedro Sánchez announced that the European Commission is also asked for evaluation to gain further insights. In Portugal, the power supply for most households was restored on Tuesday morning, while all substation of the national transmission network went into operation again on the evening of the power failure.

In addition, the role of renewable energies is discussed, since they are highly volatile and the expansion of the infrastructure often remains behind the increased proportions in energy production. Experts indicate that a stable power grid requires a balance between electricity generation and consumption. In order to compensate for fluctuations, expansion and adjustments in the network structure are necessary. At the same time, there were increased redispatch measures to avoid bottlenecks. The solar tip law, which came into force on February 25, 2025, lowers the risk of oversupply and shows how important a well -thought -out and stable network expansion is, especially with regard to the future goals, in the area of ​​photovoltaics up to 2045 400 gigawatts and at the same time not to overload the existing system.
