Natural gas corridors between the EU and its main suppliers: Simulation results with the dynamic GASTALE model

Growth in gas demand poses a challenge for European energy consumers and other gas-importing countries in terms of an increasing dependency on gas imports and consequently also supply security. This paper focuses on interactions among demand, supply, and investments in natural gas corridors, namely pipeline transport, LNG, and storage facilities, affecting the European natural gas market over the period 2005-2030. A number of policy scenarios, including a business-as-usual (BAU) scenario, are formulated to study the impact of demand uncertainty and delays in investment on the gas transport infrastructure required in the long run in Europe. The analyses indicate that substantial investments in gas transport corridors are needed to accommodate imports and seasonal demand variations. Analysis of scenarios of supply interruption, in the form of suddenly reduced import capacity for particular pipeline routes, indicates that portions of Europe could experience price increases of up to 100% in the case of a year-long interruption. To accommodate import needs and to mitigate possible disruptions, pipeline connections running from East to West need to be given special priority. (c) 2008 Elsevier Ltd. All rights reserved.
