Figure 26 shows the components of the reserve price for a bundled standard
capacity product. The reserve price is equal to the sum of the reserve prices for the
capacities contributing to the bundle. The constituent reserve prices do not neces-
sarily need to be identical.
Split of revenue from bundled capacity sales
Figure 27 shows that the revenue originating from the sale of a bundled capacity
product is the sum of its bundled reserve price plus the possible auction premium.
The revenue from the bundled reserve price must be split in proportion of the
reserve prices for the capacities contributing to the bundle. Each TSO will receive
the revenue from the reserve price for the capacity that each TSO contributes to the
bundle.
Any auction premium must be attributed to the contributing TSOs according to their
agreement subject to the approval of NRA(s). The approval must be granted no later
than three months before the start of the annual yearly capacity auctions.
A default rule exists for the split of the auction premium from bundled capacity
sales, to avoid invoicing problems that could arise if auctions occur in the absence
of approved agreements. In such cases TSOs must split the auction premiums
equally.
In summary, each TSO contributing to bundled capacity receives the revenue:
(1) from the bundled reserve price proportionally to the reserve price of its contrib-
uting capacity; and
(2) a portion of any auction premium as agreed with the other TSO and approved by
the NRA. In the absence of the approval of NRA(s), the portion is 50%.
