Case

A combination of a demand and supply situation, infrastructure cluster and the respective time reference A high daily demand situation used by TSOs in their National Development Plans to determine the resilience of their system and needs for investment A project where the respective project promoter(s) has (have) taken the Final Investment Decision A modelling approach aimed at minimising supply from each source separately, in order to identify Zone Supply Source Dependence, and replacing it with the corresponding volume from the remaining sources in such a way that the maximum minimisation of the ana- lysed supply is achieved The supply of gas at the entry of the European network as defined by this GRIP or gas delivered at the entry of a Zone A point of interconnection between two different infrastructures; an Interconnection Point may or may not be operated by different infrastructure operators The indigenous production related to each country covered in the GRIP; a Zone allocation has been carried out where relevant A notion related to the capability of a network to ensure supply demand balance in High Daily Demand Situations, including also under Supply Stress A project where the Final Investment Decision has not yet been taken by the respective project promoter(s) Means the referenced GRIP, including all Annexes; Plan and Report are used interchangeably The Case that extends the historical (last three years) trend of supply over the 10-year period covered by the GRIP; where new import pipe/LNG terminal projects are planned to come on stream the supply is adjusted in proportion to the last applicable supply situation A notion related to the assessment of Network Resilience; it refers to the ability of a Zone to offer additional room for supply arbitrage; the value of the Remaining Flexibility is benchmarked against defined limits to identify potential capacity gaps A set of assumptions related to a future development which is the basis for generating concrete value sets covering demand or supply A combination of conditions and circumstances relating to a partic- ular occurrence of demand or supply, or both; such conditions and circumstances may relate to e.g. time duration, climatic conditions, or infrastructure availability.
