How to attribute a given service to transmission or
non-transmission
Article 3(12) of the TAR NC defines transmission services as
‘the regulated services
that are provided by the transmission system operator within the entry-exit system
for the purpose of transmission’
; Article 3(15) defines non-transmission services as
‘the regulated services other than transmission services and other than services
regulated by Regulation (EU) No 312/2014 that are provided by the transmission
system operator’
.
Article 4(1) sets out the criteria for distinguishing between transmission and non-
transmission services. The defining characteristics of a transmission service are:
(a) The costs of such service are caused by the cost drivers of both capacity and
distance. It is possible to determine capacity by reference to either technical or
forecasted contracted capacity.
(b) The costs of such service are related to the investment in and operation of
infrastructure that is part of the regulated asset base for the provision of trans-
mission services.
Meeting both criteria requires the classification as a transmission service, otherwise
there is an option to classify the service as either a transmission service or a
non-transmission service.
Table 2 outlines the attribution algorithm between transmission and non-transmis-
sion services.
