Glossary Term: Quiescent Physical Notification
The Quiescent Physical Notification is a series of MW values and associated times expressing the volume of generation or demand expected to be generated or consumed (as appropriate) by an underlying process that forms part of the operation of a particular BM Unit.
QPN values are not used in Settlement, but if submitted to the System Operator are deducted from Physical Notifications to determine a net operating level to which the Dynamic Data of a BM Unit apply at a particular time. Submission of QPNs is optional.
BSC defined definition
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.
