TAR NC Implementation Document – Second Edition September 2017
Annual auction of
yearly capacity
Due date for non-
binding indication
8 weeks after
beginning of
annual auction
Demand
assessment
(to determine
whether there is
sufficient demand
[based on the
criteria] to launch
a project)
Alternative allocation process:
For each offer level, users submit
binding capacity requests through
the alternative capacity allocation
process and specify any conditions.
TSOs process requests quickly to
avoid overlap with any new cycle.
Default allocation process:
Users submit binding capacity
requests through the CAM auction
for each offer level.
Run economic test
(and a potential bid
revision process)
TSO(s) publish
demand
assessment
report
16 weeks after
beginning of
annual auction
Design Phase:
TSOs activities include:
\\
Prepare and design project
(planned offer levels, economic
test parameters, etc.)
\\
optional: conduct technical studies
\\
identify what conditions if any to
allow
\\
determine whether an alternative
capacity allocation mechanism is
needed to the default allocation
process, and design it
TSOs run public consultation
(min. 1, max. up to two months)
\\
finalise project design after
consultation
\\
submit proposal for NRA approval
TSOs
publish
results
NRA
approval
within 6
months of
the TSOs’
submission
TSOs
submit
project
proposal
to relevant
NRAs for
