ENTSOG Gas Regional Investment Plan South 2017 - Main Report

6.2.3.1.2 Between Spain and France

Following the Madrid Declaration in March 2015, a High Level Group (HLG) for Interconnections in Western Europe was established in order to follow its implemen- tation. As part of the work done in this HLG, a Joint Technical Study between Enagás, GRTgaz and TIGF related to MidCat was developed during summer 2015. Two different approaches were used in this technical study: \\ The minimum infrastructure required for connecting both countries: STEP project. \\ The infrastructures required to achieve the target firm capacity (230GWh/d from Spain to France and 180GWh/d from France to Spain): MidCat project. STEP (TRA-N-161 + TRA-N-252) In Spain, this project (TRA-N-161) consists of two pipelines (Hostalrich – Figueras and Figueras-French border), and a new compressor station in Martorell (36MW). In France (TIGF zone), the project (TRA-N-252) consists in a pipeline between Barbaira and the Spanish border. The total length of the project is 107km in Spain and 120km in France. The commissioning date of this project is 2021 in Spain and 2022 in France (TIGF). This project does not create firm annual capacities in both sides of the interconnec- tion. Consequently, the capacity created by this project is not considered in the TYNDP 2017, as ENTSOG NeMo tool only considers firm capacities on an annual basis. Nevertheless, according to a probabilistic study developed by Enagás, this project creates in the Spanish side firm capacity: 120GWh/d from Spain to France, and 110GWh/d from France to Spain. Such probabilistic analysis wasn’t performed on the French side as the behavior of the French market may change after the merg- er of zones in 2018. According to TYNDP 2017 criteria the project was defined as “Advanced non-FID”, as it received a CEF grant for FEED studies in the second CEF-E call of 2015   5) .
