2nd CEER Report on Power Losses

This report provides an overview of power losses (transmission and distribution) in electrical grids – the levels of losses, how they are defined, calculated and valued across 35 European countries. It is packed with key quality data such as the amount of technical and non-technical losses, losses in transmission and distribution systems, and procurement of losses. It also includes case studies on the reduction of contact voltage losses in the UK and the treatment of power losses by e-distribuzione in Italy. Reducing power losses contributes to greater energy efficiency and security of supply and is an important goal, not least because the costs of power losses are often passed on to consumers. This report contains a set of recommendations for good practices that could be adopted so as to better benchmark and reduce technical and non-technical losses. CEER’s findings and recommendations are based on the results of a questionnaire sent to National Regulatory Authorities (NRAs).

Please note that the report published on 23 March 2020 replaces the version published on 21 February 2020 largely due to some corrections of data from the Republic of Ireland, more information can be found in the Corrigendum.
