NSPL (Network Service Peak Load)

Network Service Peak Load is the transmission-side sibling of the capacity tag. It is set by a customer's demand at the moment its own transmission zone hits its annual peak, and network transmission charges are allocated on it for a year. Zone peaks usually land on or near 5CP days, so curtailing the right summer afternoons often reduces both tags at once.
