The creation of a single European electricity market has been moving in a positive direction. With the EU Electricity Liberalization Directive agreed by all Member States forming the framework of EU energy policy, the overarching goal is for consumers to benefit from an internal market governed by coordinated rules — for the implementation of renewables and development of the electricity network. A market-oriented European energy system also aims to make the most of different types of power generation and to optimize the costs associated with managing, maintaining and evolving the grid infrastructure.
