F.4.4 MODELLING ASSUMPTIONS

Perfect market functioning Assumption made to ensure to focus on infrastructure gaps that market or regulato- ry rules cannot address. In particular, no tariff is considered for transmission. For further information, refer to Chapter 6. Gas prices The price curves for the modelling are directly built on the gas prices in the different scenarios coming from the IEA World Energy Outlook. For further information regarding the prices, refer to Chapter 2.4 and Annex C. For further information regarding the price curves refer to sub-chapter 2.2.2 in Annex F. Supply configurations Intended at representing potential future temporary rankings of supply prices to the EU. \\ They are not intended to model long-lasting situations. \\ They aim at covering potential price situations over the next 20 years. Designed to maximise, resp. minimise, a given source when the source is cheap, resp. expensive. Price spreads Only used for the assessment in the import price spread configuration. Price spread applied to the different import routes based on publicly available information. Further information is available in sub-chapter 6.3.4.2 with input data shown in table 6.5. The import price spread methodology is also covered in Annex F. Value of Lost Load The monetary impact of a disruption in the modelling is 600 EUR per disrupted MWh. For further information, refer to Annex F. L-gas demand In TYNDP 2017, L-gas demand is modelled by setting minimum flows between concerned countries. For further information, refer to Annex F.

F.4.5 MODELLING OUTPUTS

Marginal prices Marginal prices are outputs of the modelling intended to assess the possible conver- gence of marginal prices. For further information, refer to Annex F.
