<br/><br/>
The insufficient NRAPM warning (Negative Reserve Active Power Margin) is a request to encourage more flexible parameters from generators, and inform participants of a risk of emergency instructions. A system NRAPM may be issued if there is insufficient flexibility available to ensure that generation matches demand during low demand periods.
