BSC technical definition
BSC Section X, Annex X-2 provides the technical definition of a Settlement Period as:
- A period of 30 minutes beginning on the hour or the half-hour and in accordance with paragraph 4.3 of Annex X-2.
Paragraph 4.3 of Annex X-2 defines a Settlement Period as:
- Settlement Period (j) starts at the spot time occurring at the beginning of the half hour and
ends at the spot time occurring exactly 30 minutes later. The spot time at the beginning of
one period therefore coincides with the spot time at the end of the previous period. - For the avoidance of doubt the first Settlement Period of a Settlement Day begins at the
spot time 00:00 on the current Settlement Day (D), and ends at the spot time of 00:30 for
the current Settlement Day D.
