Passengers can expect delays at Sydney's domestic terminal because of a power outage.

There has been a power interruption at the T2 terminal on Friday morning, confirmed a spokeswoman at Sydney Airport.

The power problems are causing delay at check-in and screening, the spokeswoman told AAP on Friday.

Airlines that operate from the T2 terminal include JetStar, Virgin and Tiger airlines.

The whole T2 terminal is affected by the power outage, and Sydney Airport is working to restore power.

It comes as NSW school holidays kick in.
