Cost Curves For Gas Supply Security: The Case Of Bulgaria
The authors evaluate the cost-effectiveness of various policy options and infrastructure investment proposals to improve the security of gas supply in Bulgaria, one of the most gas insecure countries in the European Union. They do this by computing 'Security of supply cost curve' for different gas supply disruption scenarios. The curves show the cumulative amount of security of supply on the horizontal axis and the unit cost of security on the vertical axis. Measures should be implemented by order or rising unit cost until the public authorities' preferred level of security is achieved.
