Communication technologies are enablers for the development of digitised power grids, allowing for the deployment of remote control and automation systems that leverage fiber or mobile networks. However, in this scenario, rural communities can be affected by a digital divide due to the limited development of these communication networks. To overcome this barrier, Enel Grids started a proof of concept leveraging an innovative low-earth orbit (LEO) communication technology, which offers worldwide coverage with performances similar to those of fiber or mobile (4G/LTE) connections.
Enel Grids conducted pilot projects in Spain and Italy to evaluate the feasibility and effectiveness of integrating the LEO technology into its distribution networks. These focused on enhancing communication between remote substations and control centres and on improving the monitoring and control of distribution assets in areas with infrastructure constraints. The pilots confirmed that LEO antennas can provide high-speed, stable connectivity with low latency and are able to reach rural and remote areas. LEO systems also proved to be cheaper and less complex compared to other satellite systems. As a next step, Enel Grids will evaluate the extension of LEO connectivity applications to connections in case of emergency.
