has the meaning given to that term in the Grid Code; Data that describes the MW levels to be deducted from the Physical Notification of a BM Unit to determine a resultant operating level to which the Dynamic Parameters associated with that BM Unit apply, and the associated times for such MW levels. The MW level of the QPN must always be set to zero. Also a set of data supplied by the System Operator for publication on the BMRS, comprising for each BM Unit a series of MW figures and associated times, which describe the MW levels to be deducted from the Physical Notification of a BM Unit to determine a resultant operating level to which the Dynamic Parameters associated with that BM Unit apply.
