TAR NC Implementation Document – Second Edition September 2017

Post-adjustment exit tariffs and exit revenues:

for exit points to storage facilities, a

tariff discount is applied, as per Article 9(1). For simplicity, one assumes that the

discount at exit points to storage facilities is 50%. This implies that pre-adjustment

tariffs are divided by 2 for exit points to storages only (cf.

TEx

_adjusted

column). With-

out any correction, the TSO would under-recover its allowed revenue at exit points

of 500€ (cf.

RE

x_adjusted

column).

Therefore, adjusted tariffs are rescaled upwards by a multiplicative factor of

500/499.33 (storage points are also rescaled as per Article 6(4)). The final exit tar-

iffs (TE

x_final

) and the final exit revenues (RE

x_final 

) are then calculated. One of the

advantages of this multiplicative rescaling factor, compared to an additive rescaling

factor, is that there is no change in the relative tariffs charged at exit points.

In conclusion, as described in the TAR NC, the CWD counterfactual is obligatory for

the purpose of consultation per Article 26 unless the proposed RPM fully coincides

with the CWD counterfactual.
