This dissertation investigates security of European gas supply (gas-SoS) giving particular consideration to gas infrastructure, notably gas transport and transit. Gas-SoS is endangered mainly by a disruption to existing supplies. For Europe, gas supply infrastructure acts as a tool to gain, maintain and expand access to new gas sources and consolidate access to existing ones. So the SoS-related (infrastructure) strategy has been assessed in the dissertation theoretically and practically, qualitatively and quantitatively.
The research objective pursued is: To describe and evaluate gas-SoS for Europe, as well as to specify prospective ways for the SoS enhancement, with a focus on European infrastructure […]. From this, two research questions have been derived:
(1) How secure are the European countries in terms of their natural gas supplies?
(2) How can the gas-SoS in Europe be improved (with emphasis on infrastructure)?
The central discussion of the study is in assessing the level of security risks which single European countries face. Thereupon, the family of SoS-indices HHI’14 has been developed. The ultimate aim is to apply and test indices. With their application the author hopes to gain insights into the indices adequacy as a policy tool for energy security developments. While the existing literature offers a number of SoS indicators to date, their usefulness has never been tested. For the first time, this dissertation has been testing the predictive success of SoS-indices. It confronted them with the economic losses in the 2009 interruption of Russian gas flows to Europe, and with the EU subsidies under the EEPR programme.
This investigation sets out that SoS-indices are rather important for a quick and coherent overview over the state of energy security for a large and diversified region like Europe. They cannot completely substitute, however, a detailed discussion of the situation in each member state.
