Overview
Transgrid, as the System Strength Service Provider (SSSP) for NSW, is responsible for ensuring sufficient system strength is available to maintain power system stability in NSW.
In a network without adequate system strength there are inherent stability issues. Generators may be unable to remain connected during disturbances on the power system, control of the system voltage becomes more difficult, and protection systems that ensure safe operation of the network may not operate correctly.
The retirement of NSW’s coal generators and the growth in inverter-based resources in the coming decade is driving an urgent need to add new sources of system strength to the power system.
Transgrid have comprehensively assessed more than 100 network and non-network options to ensure we meet the NER requirements and continue to operate a safe, secure and reliable power system. The preferred portfolio of options to meet system strength requirements is presented in the Project Assessment Conclusions Report (PACR).
Transgrid will host a webinar to discuss the key findings of the PACR on 18th July from 3pm – 4pm AEST.
The System Strength Rule Change has established new requirements for connecting parties to meet. A summary of these new requirements can be found on the System strength for network connections page.
