Offers accepted on Firm Basis Implementation
Fiona O’Donnell
Liaison Group 28 August 2012
Background
• Non-Firm/Firm access to the Transmission
introduced as option in 2005
• Option allows generators export onto the
System prior to the completion of
Transmission Deep Re-inforcements
(excepting those associated with Short
Circuit Levels)
• To date all parties accepting their offers
have availed of this option
Discussions in the context of
the Tie-Break consultation
• Possibility of parties accepting offers
on Firm only basis has been raised
• Clarity as to the practical implication
of this decision required.
How construction works will
progress
Where an offer is accepted on the
basis of Firm Access, it is the
intention of both SO’s to schedule
the shallow connection works
(including Distribution deep works)
such that their completion date coincides (in so far as possible) with
the completion of deep Transmission
Works
Example
• Project A –
FAQ = 2020
Estimated timeline for delivery of
shallow works (incl Distribution deep
works) = 2 years
Offer accepted 2012
Example - contd
• Project A Accepts offer on nonFirm/Firm basis
Works will commence on offer
acceptance (assuming group is
resolved)
Aim to delivery connection by 2014
Example -contd
• Project A Accepts offer on Firm only
basis
Works will commence circa 2018
(assuming FAQ date remains at
2020)
Aim to delivery connection by 2020
Outcome
• It is unlikely that timelines will
exactly match
• Possible Outcome
Actual connection will be delivered after
deep works are complete
Actual connection will be delivered
before deep works are complete and
project will operate on a non-firm basis
for a time
