Inter-Regional Transfer limit variation - Murraylink power transfer limit reduction due to high temperature for 23, 24 and 25 January 2021
AEMO ELECTRICITY MARKET NOTICE
Inter-Regional Transfer limit variation - Murraylink power transfer limit reduction due to high temperature.
Murraylink power transfer limit advice has been reduced based on APA advice, consistent with the high forecast ambient temperatures in the vicinity of Murraylink (Berri and Redcliffe) for 23, 24 and 25 January 2021.
