|Concentration ratio (CR)|
|European Union Electricity Market Glossary|
CR is a traditional structural measure of market concentration based on market shares, for example the concentration ratio “CR3” measures the total market shares of the 3 largest suppliers in one market.
According to the CEER Monitoring Report of 17 December 2018 on the Performance of European Retail Markets in 2017 (ref: C18-MRM-93-03, p. 9) for the household sector, there were 10 countries in 2016 with a CR3 equal to/above 90% in both gas and electricity markets, denoting high levels of concentration in those markets.
In 2017, this number fell to eight countries.
