| Summary/Abstract |
The paper investigates investments in gas infrastructure considering uncertainties in European gas markets. Furthermore, the study addresses the question of whether (more) diversification provides a (better) security of supply improvement. Thus, a stochastic optimization approach is introduced. The uncertainties focus on 2030 and 2045 in three dimensions, namely the Ukraine gas transit, future LNG prices, and the expected gas demand. Considering three diversification strategies, the model GAMAMOD-EU.sto optimizes investments in pipelines, LNG import terminals and gas storages as well as the gas dispatch. Results illustrate trade-offs between optimal gas supply and diversification strategies. Investments in pipelines to North African suppliers are made across all strategies, while the building of the Nord Stream 2 pipeline depend on the respective diversification strategy. Diversification through LNG quota changes the dispatch results significantly. Investments in storages are almost not necessary over all strategies, however, storages provide flexibility to prevent supply shortages, when diversification strategies are applied. Conclusion for policy makers regarding what is needed for preventing malinvestments and high costs in the European gas market are: an enhanced relationship between Russia and the EU and a clear vision on the role of gas in the future European energy system that reduces demand uncertainty.

| Summary/Abstract |
Over the past fifteen years, European gas markets have radically changed. In order to build a single European gas market, a new regulatory framework has been established through three European Gas Directives. The purpose of this article is to investigate the impact of the reforms in the natural gas industry on consumer prices, with a specific focus on gas prices for industrial use. The strength of the relationship between the industrial gas prices of six western European countries is studied by testing the Law of One Price for the period 1991-2009. Estimations were carried out using both cointegration analysis and time-varying parameter models. Results highlight an emerging and on-going process of convergence between the industrial gas prices in western Europe since 2001 for the six EU member states. The strength and the level of convergence differ widely between countries. Strong integration of gas markets in continental Europe, except for the Belgian market, has been established. It appears that the convergence process between continental countries and the UK is not completed. Thus, the integration of European gas markets remains an open issue and the question of how far integration will proceed will still be widely discussed in the coming years.
