Solutions - FAQs
Q: What is AEMO doing to manage these issues?
AEMO is working closely with industry to evolve the power system through solutions that maintain power system security and deliver reliable and affordable energy to consumers.
Regarding the low system strength in West Murray, AEMO declared fault level shortfall of 312 MVA at the Red Cliffs fault level node in December 2019 and is in the process of procuring services to fill the shortfall by 1 January 2021 (refer to the Notice of Victorian fault level shortfall at Red Cliffs report).
This is the third system strength gap identified for the NEM under AEMO’s system strength requirements methodology, following South Australia and Tasmania in October 2017 and November 2019, respectively.
Q: When will the tender to fill the system strength gap be announced?
Q: How big are the synchronous condensers that have been procured by AEMO?
Q: How does this all affect the timing and sequence for generation integration, and thus my Project?
This does not affect the timing and sequence that has been developed. However, as more projects are included in the WMZ, it is possible the time needed to complete assessments may be extended.
To address network congestion, alleviate thermal constraints and improve the power transfer capability from the West Murray area, AEMO is implementing a transmission infrastructure augmentation plan as outlined in our latest Integrated System Plan (ISP) and Victorian Annual Planning Report.
Two major interconnector projects that may deliver benefits to the West Murray area include:
- Project EnergyConnect: a new interconnector between South Australia and NSW, likely to be delivered within the next five years.
- VNI West (formerly “Keranglink”): a longer-term project which seeks to increase transmission interconnector capacity between Victoria and New South Wales. This project is currently undergoing a rigorous RIT-T process, with a Project Specific Consultation Report published in December 2019. VNI West may benefit the West Murray areas subject to the outcome of this RIT-T. For further information on the ongoing and completed transmission augmentation projects, please visit AEMO’s website.
