The power grid infrastructure is vulnerable to some extreme meteorological phenomena and this could create some difficulties in the safe management of the power system. The wet-snow accretion on OHL (OverHead Lines) is well-known to the Transmission and Distribution System Operators (TSO&DSO). To answer this harmful atmospheric phenomenon, RSE has developed a weather forecast system named WOLF -Wet snow Overload aLert and Forecasting- for the electric power grid warning. WOLF, together with wet snow load prediction, provides an estimation of the anti-icing current necessary to maintain lines free of snow sleeve formations. These information can support the TSO operators in adopting mitigation active strategies. In synergy with WOLF, an automatic station named WILD -Wet snow Ice Laboratory Detection- has been installed in the municipality of Vinadio in the west Alps, at an altitude of 950 m asl for the forecast system verification.

Observed data and future climate projections depict significant climatic changes over Mediterranean Region, making this region especially vulnerable to climate impacts, because of the combined effects of anthropogenic stress and natural resources.There is the risk of serious impacts on sectors like health, energy, agriculture, water resources and tourism for Italy, too, as the projections highlight an increasing of hot days and heavy precipitations events.

The aim of this work is to assess potential changes in precipitation extremes that would have serious impacts over Mediterranean basin with focus over Italian peninsula. To this aim, 5 different climatic simulations provided by Med-CORDEX project (https://www.medcordex.eu/) have been analysed. A deep analysis of the results shows that an increase of intensity and frequency of extreme events is likely and, consequently, an increase of electric failures is expected.
