deduction from full payment of will be made based on the rules below for delivery of less than the Delivery Target Threshold of Contracted Capacity.
3.2.2 The Delivery Proportion $ DP_{s,j} $ is defined as the ratio of actual MW delivery to Contracted Capacity. This ratio is a value that represents a percentage and is rounded to two significant figures to ensure it represents a whole percentage.
3.2.3 The Delivery Target Threshold (DTT) determines the acceptable under-delivery for a Dispatch Group. For every % point under that level, a fixed proportion, called the Penalisation Multiplier, (PM) of the full payment is deducted.
3.2.4 Thus, the Payment Proportion is a value between 0 and 1+PO (or 0 and 100%+PO%). The calculation contains three cases:
$$ \begin{array}{l}1)\ {i f}\ D P_{s,j}\geq(1-D T T){a n d}D P_{s,j}\leq1+P O,P P_{s,j}=D P_{s,j}\end{array} $$
$$ \begin{array}{r l}{2)\;i f\;D P_{s,j}<(1-D T T),P P_{s,j}=}&{{}M a x\big(0,1-D T T-P M.\big[1-D T T-D P_{s,j}\big]\big)}\end{array} $$
$$ \begin{array}{l} 3)~if~DP_{s,j}>~1+PO,~PP_{s,j}=~1+PO \end{array} $$
3.3.1 The total Utilisation Payments due for a given Dispatch Group in a month is calculated as the sum of the individual Utilisation Payments:
$$ M U P_{s,m}=(\sum_{e\in{\cal M}}U P_{s,e}) $$
