The ACER Country Sheets present key metrics on retail electricity markets across EU Member States for the year 2023. They give insights into the level of consumer participation at the retail level. As electricity generation fluctuates with increased renewable integration, flexible market structures and adaptive contract models will be needed across the EU to ensure system stability and responsiveness. The indicators assessed, such as pricing dynamics, fuel mix evolution, and market structure, when examined together, help to underscore the degree of flexibility within each market and how well they can adjust and support a resilient, sustainable energy transition. This guidance provides the definitions for each of the indicators presented in the Country Sheets as well as the sources from which they were derived.
