Transparency of Gas Transmission, LNG and Storage Infrastructure in Energy Community and Mediterranean Region - Compliance Monitoring
This report assesses the level of transparency in gas infrastructures – transmission pipelines, LNG facilities and storages – among the members of the Association for the Mediterranean Regulators (MEDREG) and the Energy Community Regulatory Board (ECRB). This monitoring exercise aims to achieve a minimum common transparency standard by identifying the necessary improvements and making a set of recommendations.
Although a certain level of transparency has been established among the analysed countries, improvements and further progress are required. Legislation on transparency is not yet well established among non-EU MEDREG members, which creates an impediment against the development and progression of the principle of transparency.

Guidelines of Good Practice on Third Party Access in The Mediterranean Region
This report analyses the  application of Third Party Access (TPA) in the  countries of the Mediterranean region according to several expected actions that MEDREG countries should comply with. MEDREG categorised them in three levels of recommendations:
  • recommendations applicable to all MEDREG countries;
  • recommendations applicable to MEDREG countries  where a TPA regime is in place but further actions may be necessary; and
  • recommendations applicable to MEDREG countries with more developed gas markets.
  • Overall, MEDREG countries seem to be slowly but steadily closing their regulatory gaps in terms of TPA, albeit some difference remains, notably concerning the issuing of transparent rules and the development of anti-hoarding mechanisms.

    Guidelines of Good Practice on Capacity Allocation-Work Methodology
    The purpose of this work is to assess the allocation mechanisms actually adopted in the Mediterranean region and to define MEDREG’s Good Practice Guidelines for capacity allocation. Guidelines will aim to help identify more efficient allocation mechanisms of the capacity at the interconnection points to support the development of cross-border trade and of an efficient gas wholesale market in the Mediterranean region. Given the diversity of the current adopted methodologies (first-come-first-served, auctioning, others), an initial status assessment is intended, based on a questionnaire distributed to the Regulators of the MEDREG countries. The assessment also concerns the congestion management mechanisms adopted, if any, that are strictly related to the efficient use of the capacity allocated.

    Work Methodology for the Assessment of Competition Indicators and Market prices within MEDREG members
    The Gas working group developed a first phase work methodology for the achievement of this deliverable. This report intends to provide a review of the level of competition in the retail gas markets for household and non-household consumers, across MEDREG members. Given the diversity of situations in the different countries this assessment work intends to evaluate the retail natural gas market of each country, looking for the main market competition indicators. The assessment work also includes the collection and the analysis of data related with the retail gas prices of each country, for the household and non-household segments. The information from the different MEDREG members will be obtained by a questionnaire, which will be divided in two different parts. The first part will include direct questions concerning the market competition indicators. The second part will include tables to be filled out and questions about retail gas prices for household and non-household customers. The questionnaire will be based in the most recent situation of each country

    GAS WG - 2nd Status review on Transparency in the Mediterranean region and Monitoring of the MEDREG Guidelines of Good Practice (GGP) on Transparency
    The aim of this report is to assess the progress made on transparency in the Mediterranean region since the first status review developed in 2011. The achieved results shows that the situation regarding transparency is mainly unchanged, although some progress has been detected in some countries and no major setbacks have been registered. The report also describes that the level of transparency is influenced by the existence of a legal obligation to publish information on the gas system and market. In the absence of such legal requirements, the compliance with MEDREG GGP recommendations is voluntary and may depend on the own operators’ interest and the capacity and powers of regulators to have an influence on their information disclosure policies.

    Status review on transparency in the Mediterranean region and monitoring of the MEDREG guidelines of good practice (GGP) on transparency
    One of the most important preconditions to achieve an integrated, competitive and secure gas market in the Mediterranean region is ensuring that participants in the gas markets have easyaccessible and non-discriminatory access to all the information they need. Transparency in the access to this information is therefore a key principle to observe in order to reach this objective. As foreseen in MEDREG Action Plan 2010-2012, the Ad-Hoc Group on Gas (GAS AG) has investigated the transparency status in the gas systems and markets of Mediterranean countries, and has carried out a monitoring of the guidelines and recommendations on transparency contained in the MEDREG Guidelines of Good Practice (GGP) on Transparency, approved in the 8th General Assembly of 13th November 2009. This report presents the results of this research.
