Recently, the EU-funded project "Technical Assistance to Energy Agency of the Republic of Serbia – Approximation of National Regulatory Authority tasks to the Third Energy Package", implemented by the LDK Consultants Global EEIG in consortium with GFA Consulting Group, GFA South East Europe doo, KANTOR Management Consultants S.A. and Quiddita doo, was successfully completed. One of the most important components was the support on the upgrading the market monitoring processes in AERS.

Initially, the project team performed a gap assessment between the requirements imposed by the applicable EU rules and the identified monitoring and enforcing activities of AERS, as well as an assessment of the efficiency and effectiveness of AERS monitoring activities.

The main findings of the above gap analysis were used as basis for upgrading the monitoring process of AERS. Based on existing (and new) info-codes collected from market participants (suppliers, TSOs, DSOs, etc.) several spreadsheets were prepared to support AERS internal market monitoring practices. The monitoring checklist regards spreadsheets that allow AERS to monitor the submission of required info-code: timeliness and completeness. Matching spreadsheets are used to calculate some key indicators from different sources (e.g. TSO balance vs aggregate suppliers’ sales) and through which AERS is able to check the accuracy of received data. Finally, data processing spreadsheets aim to complete current monitoring practices in order to comply with all monitoring requirements set out by ECRB questionnaires (based on ACER/CERR monitoring requirements). Besides the obtention of the key indicators to be submitted to AERS, data processing spreadsheets contain other useful indicators to upgrade AERS monitoring and reporting practices (Annual report) to be aligned with European best practices.

More specifically, the following monitoring procedures have been developed for electricity and gas: unbundling, wholesale market, retail market, access to cross-border capacity, balancing, Quality of Service, customer protection. Due to its relevance within the EU regulatory framework, a procedure has been added also for transparency. These procedures build upon the Info Code tables already in use in AERS. Where deemed necessary, additional info-code table and indicators were proposed, e.g. in the case of voltage quality. In the case of Quality of Service (QoS) data processing excels were harmonized with ECRB questionnaires where QoS indicators are included in Consumer Protection.

The newly designed business processes and data collection templates alongside the accompanying templates for background calculations will constitute an integral part of the future IT system of AERS which will automatize data collection, processing, and analysis. This will be a considerable upgrade and will entail significant efficiency and resource savings both for AERS and market participants and more importantly it will equip AERS personnel with the necessary tools for effective market monitoring.
