Low-loss solution for the Italian Energy Internet

Italy can achieve a low-loss, efficient Energy Internet through grid modernization, digitalization, renewable integration, and advanced transmission technologies.

Grid Modernization and Digitalization

Modernizing Italy's electricity distribution and transmission networks is central to reducing energy losses. Enel's ongoing investments focus on renewal of existing assets, development of new lines and substations, and implementation of innovative IT solutions for remote control and network management . Digitalization enables real-time monitoring, predictive maintenance, and optimized load management, which reduces technical losses and improves overall efficiency. Smart meters and encrypted data collectors allow operators to track energy flows accurately, supporting a bidirectional grid that integrates prosumers and distributed generation .

High-Efficiency Transmission and Distribution

Terna, Italy's national transmission operator, is investing €16.6 billion to expand and strengthen the national grid, including high-voltage lines and substations . Upgrading transmission infrastructure with low-resistance conductors, high-voltage direct current (HVDC) lines, and advanced transformers minimizes resistive losses over long distances. Reinforcing primary and secondary substations ensures stable voltage levels, reducing losses associated with voltage drops and improving energy delivery to end users .

Renewable Integration and Flexibility

Integrating renewable energy sources efficiently is key to a low-loss Energy Internet. Italy aims for at least 53% renewable electricity consumption by 2030, with solar and wind capacity projected to reach 90 GW . Flexible thermal resources, energy storage, and demand-side management help balance intermittent generation, reducing curtailment and transmission losses. Distributed generation close to consumption centers also shortens transmission distances, further lowering losses .

Advanced Energy Management

Digital platforms and smart grid technologies allow utilities to optimize energy flows, forecast demand, and dynamically manage distributed resources . By leveraging AI-driven load balancing and predictive analytics, Italy can minimize congestion and reduce losses in both transmission and distribution networks. This approach also supports resilience against climate events, ensuring continuity of supply while maintaining efficiency .

Conclusion

A low-loss Italian Energy Internet relies on a combination of infrastructure upgrades, digitalization, renewable integration, and advanced energy management. Investments in smart substations, high-efficiency transmission lines, and real-time monitoring systems, alongside flexible generation and storage, will enable Italy to meet growing electricity demand while minimizing losses and supporting a sustainable, resilient energy system .
