Market participants benefit from harmonized trading systems, one single rulebook and one admission process for the entire region, therefore reducing trading costs and lowering entry barriers for new participants. Moreover, they have access to a wider range of products and benefit from best-of-both standards and reliable customer support. Overall, the integration led to a more effective governance and further facilitated the creation of a single European power market fully in line with the objectives of the European electricity regulatory framework.
