“…Initially, scientists paid particular attention to the Scandinavian countries (e.g., [14,36]). However, several studies have shown that this is not only the case for just most high-latitude countries (e.g., [37,38]). It has to be mentioned that the only blackout that appeared in Europe as an effect of space weather events was the Malmö blackout during the so-called Halloween Storm [39].…”

The Quebec blackout on 13 March 1989, has made geomagnetically induced current (GIC) research a socially important field of study. It is widely recognized that the effects of space weather, which may affect the power infrastructure, threaten countries located at high latitudes. However, in recent years, various studies have shown that countries at lower latitudes may also be at risk. One of the best proxies of GIC variability is the local geoelectric field, as measured in Eskdalemuir, Lerwick, and Hartland, by the British Geological Survey or modeled using, e.g., a 1D layered Earth conductivity model. In our article, we present a review of the issues related to the impact of the GIC on transformers and transmission lines in Central and Southern European countries, from Greece, Spain, and Italy to Slovakia, the Czech Republic, Austria, and Poland. The review underlines the importance of the systematic collection of information about power grid failures and the need for further systematic studies of the GIC’s impact on the operation of power grids in mid-latitude countries.

“…In mid-and low-latitude countries, GIC can be a source of the transformers' failures through the transformer insulation repeated heating [11,12]. Over the last few years, substantial magnetic field rates of change have also been noticed in near-equator latitudes at coronal mass ejecta arrival moments [13,14] and even in the quiet period of the solar activity cycle 24 (the year 2017) at Malaysia region [15]. It is worth mentioning that in Gil et al [16] we have shown, using the Wilcoxon Matched Pairs Test, that the greater value of Kp index, the higher is the amount of Polish transmission lines failures caused by the aging of elements.…”

We analyze the solar influence of space weather events on Polish energy infrastructure via geomagnetic disturbances. We consider two time intervals of very different levels of solar activity (SA) in the course of the solar activity cycle 24: 2010—an early rising phase of SA, near the solar minimum and 2014—solar maximum. From the total number of electrical grid failures, we extract almost five thousand failures in 2010 and more than ten thousand in 2014, which could be related to space weather effects. We analyze data of failures having unidentified causes, failures coupled with the aging of transmission network elements and electronic devices, which appeared during the time intervals of enhanced geomagnetic activity. We show that around the times of increasing geomagnetic activity level, the amount of transmission lines failures in the groups mentioned above grows, but mostly with some delay. It might be connected to some cumulative effect due to the result of transient states and their propagation in the distribution network. Although we do not exclude that the other factors may play a role, the solar-originating disturbances strengthen these effects.
