ENTSOG GRIP South - Main Report

NETWORKASSESSMENT

South Gas Regional Investment Plan 2013–2022 deeply analyses themain results regarding the South Region obtained in theNetwork assessment chapter from the ENTSOG TYNDP2013–2022. 1) The results of the ENTSOG TYNDP assessment give an overall indication of the level of infrastructure-related Market Integration. For the purpose of the report, Market Integration is defined as a physical situation of the interconnected network which, under optimum operation of the system, provides sufficient flexibility to accommodate variable flow patterns that result from varyingmarket situations. The achievement of thedesired level of Competition, Security of Supply andSustainability is enabled through the achievement of desired level of market integration. Market integration canbemeasured at two levels: \\ Commercial (determined by themarket behaviour and business rules applicable on the respectivemarket) \\ Physical (determinedby level of physical interconnection between the different infrastructures systems of the respectivemarket). The TYNDP assessed the physical layer of Market Integration through 4 assessments which analyse the way infrastructure can sustain the supply-demandbalanceunder various supply-demand situation and infrastructure configuration.
