Interconnected power systems: a technical and economical optimization for the benefit of energy transitions in France and in Europe

The roles and missions of TSOs go way beyond the implicit meaning of the term 'power transmission'. At the heart of the power system, we are responsible to keep the balance between supply and demand. By ensuring that we have the ability to fulfill this role on a daily basis, we provide our customers with economical, reliable and clean access to power supply. Operating the power system is all about optimization. Firstly, by mutualizing energy sources at the European level, RTE insures 'power' solidarity between regions and enhance renewable energy sources contribution. Secondly, the market mechanisms that we are developing make it possible to use the most competitive energy sources in France and in Europe. This optimal use of resources call for close cooperation with our European counterparts. These mechanisms support security of supply and economic optimization of the system, while also facilitating other ways to consume power. Overall, we promote solutions to help making decisions based on physical and economic parameters, always seeking the most advantageous solution and ensuring grid operability. RTE is constantly seeking ways of remaining a step ahead of changes within the power system. In the energy transition context, French economic competitiveness also relies on optimal efficiency of the power system. Our ambition is to developing a smart transmission system to support tomorrow's economy and energy landscape, in conjunction with our partners. (author)
