In fact, in this latter case, the impacts on business can be considerable but, as shown in cases that occurred in the past and in various areas around the world, the Group has shown absolute resilience thanks to the wide insurance coverage limits, which are also the result of a solid reinsurance structure, as regards the Group’s captive company Enel Insurance NV. Management of acute physical risks regarding the generation of electricity The Group performs various control activities to manage the impact of weather events on electricity generation, such as: › weather forecasting both to monitor renewable re source availability and detect extreme events, with warning systems to ensure the protection of people and assets; › hydrological simulations, territory surveys (also using drones), monitoring of possible vulnerabilities using digital GIS systems (Geographic Information System) and satellite measurements; › advanced monitoring of more than works; › real-time remote monitoring power plants; › safe rooms in areas exposed to tornadoes and hurricanes; › adoption of specific guidelines for carrying out hydrological and hydraulic studies that are targeted, from the first development phases, toward assessing risks inside the plant and toward areas external of the plant, with the application of the principle of hydraulic invariance during the design of the draining and mitigation works; › check of potential climatic trends for the main project parameters in order to keep the dimensioning of the systems into account for relevant projects (for example, assessments of the temperature of a cold source to guarantee greater flexibility for cooling the new CCGT); › estimate of extreme wind speed using updated databases containing the registers and historical trajectories of hurricanes and tropical storms, with the resulting selection of the wind turbine technology that is best suited to the conditions that were found.
