This report presents the work that Pöyry has undertaken over a number of months since May 2011. In the course of this work we have interviewed a large number of industry stakeholders in order that we are able to understand the views of market participants and to develop a practical approach to liberalisation in Estonia. The Estonian gas market is, by international standards, small in terms of its annual consumption and peak day gas requirements. There is currently very little gas used in power generation in Estonia, although gas does have a reasonable share in CHP and district heating schemes. The Estonian gas transmission network is connected to Russia at Narva and Värska and to Latvia at Karksi. Even though connection at Narva has had periods out of operation due to its poor condition, and currently has limited availability, there is currently sufficient capacity in the transmission network to meet all annual and peak gas demands. The major player in the Estonian gas market is Eesti Gaas, which owns the transmission system assets, the majority of the distribution assets and is currently the sole wholesaler of gas. It is owned by Gazprom (37%), E.On (33.66%), Fortum (17.7%), Itera (9.9%) and various smaller shareholders. Eesti Gaas supplies gas to over 90% of the retail market. The sole importer of gas into Estonia is Gazprom. Flexibility is also provided to the Estonian gas market via the Incukalns underground storage facility in Latvia, which is currently contracted solely to Gazprom. In order to progress towards a liberalised market, Estonian legislation has led to the establishment of a separate system operator, EG Võrguteenus, in January 2006, which is a wholly owned subsidiary of Eesti Gaas. Since July 2007, the Estonian gas market has been open to competition, with all end users, in theory, being able to choose their gas supplier. Despite these efforts, however, little or no competition has developed in the gas market. We consider that this has been due to a number of reasons: The overall size of the gas market is small and therefore not attractive to new entrants that would incur high start-up costs in relation to any possible benefits. There is no alternative to Russian gas supplies and therefore no gas-on-gas competition at the wholesale level. There is no surplus of gas available to the wholesale market to provide new entrants with competitive prices. End user prices have been relatively low, in comparison to other EU countries, and therefore there has been little incentive for end users to question the status quo. Competition in the electricity sector is not yet established at the retail level and this has meant that it is not possible for either the gas or electricity incumbents to offer dual fuel offers. In other markets this has led to at least the gas and electricity incumbents competing with each other. Retail customers have little choice of their gas supplier if they are tied into district heating schemes. Furthermore, the limits that are imposed on the use of a single fuel source in district heating schemes may incentivise a move away from gas and into biomass. PÖYRY MANAGEMENT CONSULTING October 2011 573_Estonian_Liberalisation_v1_0.docx 1 LIBERALISATION OF THE ESTONIAN GAS MARKET Currently, there is little gas fired power generation in Estonia, and a vibrant gas fired power sector is normally key to attracting new market entrants. This report addresses the issues detailed above and presents a number of conclusions and recommendations on the future development of the Estonian gas market.
