ENTSOG TYNDP 2017 - Annex F - Methodology

6 Monetisation Several outputs can measure the evolution of the situation:  The EU bill

 The marginal price for each Zone (linked to consumer surplus)  The monetisation per Zone, only measured as a difference between two infrastructure levels.

6.1 MONETISATION AT EU LEVEL Monetisation 6.

The monetary analysis is based on the calculation of costs for Europe. The EU bill is also the function that the model tries to minimise, ensuring consistency between the results provided and the target of improving the situation for Europe as a whole. In TYNDP, results of the monetisation illustrate the potential evolution of the gas bill from one scenario to the others. Monetisation at EU Level 6.1. The monetary analysis is based on the calculation of costs for Europe. The EU bill is also the function that the mod l tries to minimise, ensuring consis ency b tween the results provided and the target of improving the situation for Europe as a whole.

In TYNDP, results of the monetisation illustrate the potential evolution of the gas bill from one scenario to the others.

6.2 MONETISATION OF DISRUPTION

The disruption is monetised ex-post, based on the disrupted quantity (demand cur- tailment) resulting from the modelling and the Value of Lost Load form the input data (VoLL). 6.2. The disruption is monetised ex-post, based on the disrupted quantity (demand curtailment) resulting from the modelling and the Value of Lost Load form the input data (VoLL). Monetisation of Disruption = Disrupted Quantity ∗ VoLL Monetisation of Disruption
