F.4.2 SUPPLY
Data is collected from external sources based on publicly available information, in
order to define a range of supply from each of the various sources. Supply potentials
considered in the TYNDP are not forecasts.
Supply potentials
Range of supply (min and max) considered in the modelling.
For further information, refer to Chapter 3.
Supply data
The data is available in Annex C.
Indigenous production
Data collected from TSOs having an upstream connection with the production
system.
Storage technical data
Existing data provided by GSE, based on storage operators data. Project data is
provided by promoters. Data collected:
\\
Storages Working Gas Volumes (WGV)
\\
Injection and withdrawal capacities
\\
Withdrawal deliverability curves
Storage modelling assumptions
Storage levels over the whole year: in average conditions, the model will make use
of the storages so that on April 1st (end of winter and beginning of summer), the
levels of every balancing zone is 30%.
LNG technical data
existing send-out capacities and LNG tank storage volumes are provided by GLE,
based on LNG terminal operators data. Project data is provided by promoters. For
further information on the Regasification capacities assumptions can be found in
Annex F.
LNG modelling assumptions
\\
Design case (Peak day): regasification level up to a maximum send-out capac-
ity provided by GLE. Regasification level includes the use of LNG stocks in
tanks.
\\
2-week cold spell: Regasification level can go up to a maximum send-out
capacity provided by GLE, but terminal behaviour distinguished between 1
st
and 2
nd
week. 1
st
week: no additional cargo can support the regasification
compared to winter simulation (winter emissions set a cap), but regasification
level can be increased using LNG stocks in tanks. 2nd week: additional cargos
can support the regasification level.
