Methodology, objective, background

In 2011 a dedicated market monitoring team commenced the work on the first market monitoring report. Starting from the relevant legislation, they developed a methodology to assess retail markets, network access and wholesale market integration to detect market barriers. From this a set of indicators emerged for each of these three areas, which have been debated with national regulators, the European Commission and other relevant stakeholders.

The same methodology was applied for the second market monitoring report and the third market monitoring report covering respectively 2012 and 2013.

The Market Monitoring team draws from public and non-public data sources to fill the selected indicators. For instance, the Agency is sourcing data from national regulators and benefiting from work executed by national regulators through CEER. As regards to public sources the Agency collects for example data from ENTSO’s platforms and Energy Markets Observation System (EMOS). In sum, a vast majority of the data used in the market monitoring report is publicly available.

Within the context of Regulation (EC) No 715/2009 and Directive 73/2009, Network Codes (NCs) and Guidelines (GLs) were to be created. These regulations also established ACER’s market monitoring responsibilities in terms of implementation and economic effects of NCs on market performance. In order to prepare and implement a monitoring framework for gas in 2015 the Agency commissioned a consultancy study for a methodology proposal to evaluate the impact of the gas Network Codes and Guidelines in terms of implementation and market effects. The study went through market consultation between 12 June and 17 July 2015.

The final report and the presentation of the study are accessible below:
