\nCVA Group<\/a> is one of Italy\u2019s leading renewable energy producers,<\/strong> with more than 1.3 GW of installed capacity across hydropower, wind and solar plants. Fully publicly owned and controlled by the Autonomous Region of Aosta Valley, the Group operates across the entire green energy value chain and, through its subsidiary DEVAL, manages almost the entire regional electricity distribution network.<\/span>\u00a0<\/span><\/p>\n

As part of a growth path that also aims to double installed capacity, CVA chose to strengthen the climate resilience of its infrastructure with tools able to read risk in a more quantitative, granular and forward-looking way.<\/strong><\/span>\u00a0<\/strong><\/p>\n

For those managing electricity networks in mountainous areas, climate risk has a specific layer of complexity. Infrastructure runs through narrow valleys, crosses areas with high hydrogeological hazard, and is simultaneously exposed to multiple risks<\/strong> such as floods, wildfires and landslides. Official maps remain an essential reference, but they do not always provide the level of granularity needed for asset-level decisions. Detailed engineering assessments, on the other hand, are time-consuming and difficult to scale across an entire region.<\/span>\u00a0<\/span><\/p>\n

A further dimension is now impossible to ignore: the future. It is no longer enough to understand today\u2019s risk. It is also necessary to understand how that risk may evolve over the coming decades,<\/strong> in order to guide investments, adaptation strategies and operational priorities.<\/span>\u00a0<\/span><\/p>\n

It is in this context that CVA started working with Eoliann, selecting as a first scope of analysis part of its electricity network and 20 substations in Aosta Valley, with the aim of moving towards a more advanced approach to climate risk assessment.\u00a0<\/strong><\/p>\n

The project<\/span><\/b>\u00a0<\/span><\/h2>\n

CVA and Eoliann jointly developed a project based on Airis<\/a> technology.<\/strong> Rather than limiting the work to hazard assessment alone, the analysis covered the full risk chain: from the probability and intensity of events to asset vulnerability, all the way to the estimation of expected economic damage.<\/span>\u00a0<\/span><\/p>\n

CVA provided the geospatial data of the network, guided the selection of the pilot assets, and contributed its knowledge of the territory to validate the results.<\/span>\u00a0<\/span><\/p>\n

    Asset segmentation and analysis<\/span><\/b><\/h3>\n<\/li>\n<\/ol>\n

    Power lines were divided into 30-metre segments,<\/strong> consistently with the resolution of the models. Each segment and each substation were then analysed through Eoliann\u2019s proprietary models, trained on satellite data, climate variables and geomorphological features of the territory.<\/span>\u00a0<\/span><\/p>\n
