ACER, the EU Agency for the Cooperation of Energy Regulators, contributes to Europe’s broader energy objectives, including the transitioning of the energy system at lower cost, by: • Developing competitive, integrated energy markets across the EU via common rules and approaches, thereby enabling reliable and secure energy supply at lower cost • Contributing to efficient trans-European energy infrastructure and networks, enabling energy to move across borders, thus enabling energy choices at lower cost and furthering the integration e.g. of renewables • Monitoring the well-functioning and transparency of energy markets, deterring market manipulation and abusive behaviour.
