Sun eclipse on Saturday: Austria's power supply remains stable!

Österreich, Land - On March 29, 2023, a partial solar eclipse will be visible about Europe, which will also have an impact on electricity generation in Austria. In Denmark, experts expect a ring -shaped darkness with a shading of around 23 percent, while Austria has to expect around seven percent to be darkened. This shading has direct consequences for the performance of photovoltaic systems that have become increasingly important in recent years.

According to the transmission system operator Austrian Power Grid (APG), the solar eclipse will lead to a loss of around 300 megawatts between 11:30 a.m. and 12:55 p.m. This roughly corresponds to the performance of a large Danube power plant. Despite these short -term losses, APG assures that the stability of the power supply in Austria is not at risk. The reduced performance can easily be compensated for by existing measures in network management and exchange with other European countries.

preparation and planning

The planning for such events takes place months in advance. The maximum predicted performance reduction in the worst case is estimated at around 21 gigawatts, which corresponds to about five percent of the top load of the entire synchronized power area and twice as much as the top load of Austria is. This planning is part of the extensive preparations that APG has made in recent years.

In view of the increasing importance of renewable energies, Austria has an ambitious goal: by 2030, the country's electricity requirements are to be fully covered by sustainable energy. The proportion of photovoltaics in electricity generation is significant when expanding. The PV share in Austria is expected to increase from currently two to eleven terawatt hours a year. APG is therefore investing a total of 640 million euros in the infrastructure by 2025 and is planning long-term investments of around 9 billion euros to 2034 for network exhibition and conversion.

power supply security

APG operates a network of around 3,500 kilometers and can ensure security of supply of 99.99 percent. Close international cooperation with other transmission network operators is a key element to cope with the challenges associated with such a solar eclipse. While the immediate effects of the impending darkness are relatively low, it is forecast that future solar eclipses could have a greater impact on the power grid. The company therefore plans to further expand, reinforce and digitize its infrastructure in order to be prepared for future events.

Overall, the preparations from APG show that Austria is well prepared for the upcoming challenges that the increasing use of renewable energy sources brings. These measures are crucial to successfully design the energy transition and to ensure the power supply even in exceptional situations. The population can thus look forward to the solar eclipse.
