ENTSOG TYNDP 2017 - Main Report

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.
