Bij een enkelvoudige storing is een onderbreking van maximaal 10 minuten met een maximale belasting van 100 MW toegestaan.
Hierbij hoeft alleen rekening te worden gehouden met de als gevolg van de leveringen dan wel afnamen optredende belastingen tijdens de onderhoudsperiode.
New Zealand/AOTEAROA
The single contingencies to be considered under an N-1 criterion are:
- loss of a single transmission circuit
- loss of a single generator
- loss of an HVDC pole
- loss of a single bus section
- loss of an interconnecting transformer
- loss of a single shunt connected reactive component, e.g. capacitor bank, SVC

Notes
A more stringent criterion that considers simultaneous outage of two critical components (i.e. “N-2”) may also be adopted in critical parts of a power transmission grid that require a higher level of reliability.
