In last years the energy transition towards renewable energy became a global priority in order to combat climate change and ensure long-term energy security. According to European Union’s climate objective and the United Nations sustainable development goals Italy should achieve at least 72% electricity generation from renewables by 2030. Although renewable energy capacity is distributed across the country, Northern Italy which accounts for the highest electricity demand due to its dense population and industrial activity still depends heavily on electricity imports, particularly from France and Switzerland. To reduce electricity imports and improve regional energy self-sufficiency, it is essential to increase large-scale photovoltaic generation in Northern Italy, thereby contributing to national and EU climate goals.
