Inter-Regional Transfer limit variation: F2 Transformer Victoria Region.
Inter-Regional Transfer limit variation: F2 Transformer Victoria Region.
AEMO has been advised by AusNet that due to prior loading conditions the South Morang F2 transformer pre contingent and post contingent loading must not exceed 1000 MVA.
To maintain power system security and in order to achieve this outcome AEMO has now applied a limit of 1000 MVA to the F2 Transformer in NEMDE.
