V The solution The Grtgaz network is divided into 4 operating areas with each about 15 sub-networks. Model s Hypothesis A Sub-network : set of pipelines with homogeneous higher heating value and gas density Block : set of pipelines with homogeneous pressure Z = f(hhv ave ; Density ave ) LP = f(pressure ave ; Z) High Heating Value and Density sensor Pressure sensor figures: 60 sub-networks 500 Blocks 1500 pressure sensors 250 HHV sensors 150 density sensors 17

VIII Benefits A. Business & Financial : Will contribute to reach the operating costs reduction objectives fixed by the Energy Regulation Commission Significant input data improvement as part of the current fine-tuning of GRTgaz s real-time optimization & supervising applications Expected reduction in operating costs connected with the intra-day flexibility sourcing Extra level of control of GRTgaz intra-day consumption forecast (consolidation of the tendency) B. IT Easy to use and develop by business Update of an existing tool No need for the service of a third party company 29
