Gas Regional Investment Plan of the South Region 2017 | 79
6.2.3.1.1 Between Portugal and Spain
Capacities will be reduced starting 2019. As the export capacity PT> ES depends on
the internal demand in Portugal, the Portuguese TSO does not assume all the firm
capacity in VIP Iberico. In this sense, the capacity value was reduced from 80GWh
to 62GWh from 2019 to 2021. The capacities of VIP Iberico are reviewed, updated
and agreed every year by REN and Enagás3), and the changes in capacities are not
related to any infrastructure development.
3rd Interconnection between Spain and Portugal
The 3rd Interconnection Portugal –Spain will connect Celorico da Beira to Zamora
(pipeline Celorico/Vale de Frades) with a DN700 (28”) pipeline with a total length of
248km. The project is developed in two stages, comprising different phases in each
of the countries.
The first stage of the 3rd Interconnection between Spain and Portugal comprehends
the first phase of the project (TRA-N-283) in Portugal and the first phase of the pro-
ject (TRA-N-168) in Spain. The first phase of the 3rd Interconnection Portugal –
Spain is a pipeline with 162km from the junction station JCT 13200-Celorico da Bei-
ra, in Guarda, developing to the North to Vale de Frades direction (in the Portuguese/
Spanish border) and getting into Spain to Zamora with a length of 86km. Through-
out the pipeline in Portugal there are five intermediate stations and also a Custody
Transfer Station (CTS) in Vale de Frades. In this first phase in Spain there will still be
compression reinforcement in the Zamora Compressor Station.
The first phase of the 3rd Interconnection Portugal –Spain will have a capacity from
Spain to Portugal of 70.0GWh/d and from Portugal to Spain of 70.0GWh/d. The
commissioning date for this infrastructure is early 2021.
The 2nd stage of the 3rd interconnection PT-ES comprises two projects in Portugal
(TRA-N-284 and TRA-N-285) and one project (TRA-N-729) in Spain. In Portugal,
the second phase of the project will include the installation of a compression station
on the pipeline between the JCT 11000-Cantanhede and BV 11300-Mangualde sta-
tions, with a capacity of 12MWh for flow rates of 500,000 to 550,000m³ (n)/h and
an impeller of 35 bar. In the second phase a second gas pipeline with approximately
67 km of extension will be built, parallel to the pipeline between the JCT 11000-
Cantanhede and BV 11300-Mangualde stations. In Spain, the second phase
comprises the construction of a Guitiriz-Zamora-Adradas gas pipeline with a total
length of 625km.
The completion date for this stage is the end of 2025. The final capacity is
139.0GWh/d from Spain to Portugal, and from Portugal to Spain the capacity is
126.0GWh/d.
These two projects are considered less-advanced in the TYNDP, according the
maturity of the project in Spain.
In August 2015, REN received a Connecting Europe Facility (CEF) grants from
Innovation and Networks Executive Agency (INEA) for cartography and engineering
studies for the 3rd Interconnection Point on Portugal side4).
