Ladder size ≤ 15 minutes
For each date and each Programme Time Unit (PTU), the graph and the table entitled ‘Ladder size ≤ 15 minutes’ show all bids of regulating and reserve capacity with a dispatch time of ≤ 15 minutes offered to TenneT. Furthermore, they show the size of the secondary reserve (≈ regulating margin) recommended in the UCTE policies. TenneT uses this ladder to maintain and restore the national balance.
