BENCHMARKING, EQUALISATION
AND RESCALING
Responsibility: subject to consultation per Article 26(1) by TSO/NRA, as NRA
decides; subject to decision by NRA
General
As explained above, the TAR NC explicitly lists a limited number of ‘adjustments’ to
the application of RPM: benchmarking, equalisation, rescaling and adjustments at
entry-points-from/exit-points-to storage facilities, at entry-points-from LNG facilities,
or at entry-points-from/exit-points-to infrastructure ending the isolation of MSs.
ENTSOG received stakeholder feedback requesting to outline that benchmarking
and rescaling are assumed to be and must be specified as ex-post adjustments.
ENTSOG agrees with this feedback. All the adjustments listed in Article 6(4) are in-
deed the ex-post ‘adjustments to’ the applied RPM as foreseen in the TAR NC. The
list of four adjustments included in the TAR NC does not prevent the use of various
steps in constructing the proposed RPM. Regardless of the proposed RPM and its
steps, the key procedural requirements entail periodic consultation, comparison
against CWD, and NRA approval.
Figure 14 represents the different adjustments in use or envisaged to be used by the
EU TSOs as of September 2017.
