Updated Victorian system normal voltage stability limit for the south-west Victoria
AEMO ELECTRICITY MARKET NOTICE
Refer to Market Notice 101368
AEMO has completed a review of the system normal voltage stability limit in the south-west Victoria as a result of Mortlake terminal station cut-in on the Haunted Gully to Tarrone 500 kV line.
The revised limit is increased by 100 MW on the cut-set from Haunted Gully to Moorabool and Mortlake to Moorabool 500 kV lines for flow towards Moorabool.
Full details on the limits advice are to be published shortly on the AEMO website: https://www.aemo.com.au/energy-systems/electricity/national-electricity-market-nem/system-operations/congestion-information-resource/limits-advice
The revised limit has been implemented at 1201 hrs on Tuesday 29th April 2025, by updating V^^V_NIL_SWVIC.
