  1. Current status of the existing interconnections between France and SpainERGEG – 2nd implementation meeting group of the South GRI ERGEG, 11 Décembre 2006

  2. The TIGF infrastuctures current situation IP with GRT Gaz IP with NATURGAS IP with ENAGAS DORDOGNE IP with TEPF HERAULT LACQ BIRIATOU LARRAU - ERGEG, 11 Décembre 2006

  3. LARRAU interconnection Point> North to South Flow DORDOGNE Mont’s compression station 3 Units of 3,5 MW each HERAULT BIRIATOU • Conditions at Larrau IP: • Pressure : 61 bar(a) – 269000 Nm3/h • ΔP : +0,048 bar(a) / 1000 Nm3/h ALCAY Flow direction LARRAU • To increase capacities • Decrease the IP Pressure • As is Larrau IP situation : • Capacity : 81,5 GWh/j • Larrau pressure : 62,5 bar(a) • Mont pressure : 78 bar(a) • Mont required power : 7 MW - ERGEG, 11 Décembre 2006

  4. LARRAU interconnection Point> South to North Flow DORDOGNE HERAULT BIRIATOU ALCAY Flow direction LARRAU As is Larrau IP situation : Non bidirectional (only North to south) Firmed capacities = 0 To create capacities => Invest in a reversibility equipments at Mont and Alçay sites - ERGEG, 11 Décembre 2006

  5. BIRIATOU interconnection Point> North to South Flow DORDOGNE • Conditions at Biriatou IP: • Winter Pressure : 20 bar(a) • Summer pressure : 35 to 40 bar(a) HERAULT BIRIATOU Flow direction LARRAU • As is Biriatou IP situation : • Winter capacities : 0 • Summer capacities : from 2 to 10 GWh/j • => “Lacq - Arcangues” pipeline congested • To increase capacities • Increase IP pressure • => Invest in a new « Coudures – Arcangues » pipeline - ERGEG, 11 Décembre 2006

  6. BIRIATOU interconnection Point> South to North Flow DORDOGNE Lussagnet Pressureconstraint : 50 bar(a) • Conditions at Biriatou IP: • Winter pressure : from 29 to 33 bar(a) • Summer pressure : 36 bar(a) HERAULT Lacq Pressure constraint : 50 bar(a) Bergara warranty pressure : 40 bar(a) Flow direction BIRIATOU LARRAU • As is Biriatou IP situation : • Winter capacities : 5 GWh/j • Summer capacities : 3 GWh/j • To increase capacities • Increase the IP pressure - ERGEG, 11 Décembre 2006

  7. Commercial status report at IPs From January 2006 till now From July 2006 till now - ERGEG, 11 Décembre 2006
