The Energy Union is one of the key projects for the Union not only ensuring secure, affordable and climate-friendly energy but also putting households and business consumers at the heart of the European energy market. However, so far obstacles remain that prevent consumers to fully benefit from ongoing energy transition, to meaningfully control their consumption and to lower their bills. The CoR Rapporteur highlights in his opinion the important role played by local and regional authorities in implementing European legislation, creating and financing infrastructure for distribution, metering and managing energy demand, managing decentralised production, sharing best practices, as well as informing and advising energy consumers. He asserts that smart grids and meters that are affordable, cost effective, efficient, safe and adapted to consumers’ needs and expectations should be put in place to make consumers more independent and responsible for their energy consumption. In this context, the rapporteur stresses the need to ensure the proper management and use of metering data and calls to adopt at the EU level a strict framework for the security and protection of customers’ private life. A further cornerstone should be simple, clear, comprehensive, appropriate, reliable and independent information on energy, adequate comparison tools, as well as instruments and services to make bills easier to understand. He also calls on the European Commission and the Member States to create a regulatory framework to ensure a level playing field for prosumers as new market players.
