TAR NC Implementation Document – Second Edition September 2017
Services and Tariffs
ARTICLE 4 OVERVIEW OF ALLOWED TARIFFS
As Figure 5 shows, the TAR NC splits all the regulated services provided by TSOs
into two categories: transmission services and non-transmission services. For trans-
mission services, network users pay capacity-based transmission tariffs, and com-
modity-based transmission tariffs if applicable. For non-transmission services,
network users pay non-transmission tariffs.
\\
Capacity-based transmission tariffs are set on the basis of reference prices
derived in accordance with the RPM. Chapter III ‘Reserve prices’ explains in
detail how to set such transmission tariffs for points where the CAM NC applies.
\\
The TAR NC also allows for setting specific transmission tariffs that consider
‘conditions for firm capacity products’
. Such transmission tariffs are only
capacity-based, and cannot be commodity-based.
\\
The TAR NC only allows two types of commodity-based transmission tariffs, as
explained further below.
\\
The setting of non-transmission tariffs depends on the relevant non-transmis-
sion service.
