CHAPTER VINCREMENTAL CAPACITY PROCESS
Article 29Auctioning of incremental capacity
1.
Subject to the completion of the steps provided for in Article 27, the involved transmission system operators shall offer the incremental capacity together with the respective available capacity in the annual yearly capacity auction as standard bundled products in ascending clock auctions according to Article 17 as a default and in accordance with Article 8(8) and (9) and Article 19. F1Where relevant, the transmission system operators must endeavour to work with any concerned non-UK TSO to offer the incremental capacity in accordance with this paragraph.
2.
The auctions for the respective offer levels shall be conducted in parallel and independently from each other in accordance with Article 17 and subject to Article 8(2). Only coordinated offer levels shall be auctioned.
3.
In order to minimise potential auction premia and to achieve a positive economic test outcome for the highest possible offer level, a new auction may be initiated once and only if:
(a)
there were at least two offer levels set by the transmission system operators F2and, if applicable, non-UK TSOs before the start of the auctions described in paragraph 2; and
(b)
at least one offer level was unsuccessful and resulted in a negative economic test; and
(c)
the next smaller offer level of the lowest unsuccessful offer level resulted in a positive economic test, and cleared with an auction premium for at least one yearly standard capacity product.
If these conditions are met, the new auction may be initiated for the lowest unsuccessful offer level referred in point (b).
4.
If the new auction does not result in a positive economic test outcome, the allocation results of the original auction referred to in point (c) shall prevail in accordance with Articles 17(20) and (21).
