Australian wholesale power price update May 2026

Re: Australian wholesale power price update May 2026
I didn't mention curtailment for other NEM states.
Basically Tas is next to zero due to the hydro network flexibility to accomdate changes in RE output.
SA is the highest at 11% due to limited connectivity to the east coast and large RE production
Vic is next at 6% due to large RE penetration
Qld and NSW is around 2 - 2.5% due to reasonable hydro capacity to bank and some flexibility in coal to curtail.
SA's curtailment problem will be mostly solved once the new HV line to NSW is up and running with SA then becoming a net exporter as it curtails as much as it imports + existing exports.
NSW and Qld will also be able to use SA as a sink for excess supply assuming SA is in defict at the time.
