Determination - Basslink and Hydro Tasmania system security network support payment and payment methodologies

The AER has made its determination on whether APA’s proposed expenditure/methodologies for Basslink system security network support payments are likely prudent and efficient.

The AER has determined that the payment terms in the proposed contract are prudent and efficient. The proposed contract is for Hydro Tasmania’s continued provision of the load shedding and generation tripping services required under the existing Tasmania Frequency Control System Protection Scheme (FCSPS). Basslink is required to have these FCSPS services in place by 1 July 2026 to enable the interconnector to continue to operate at its full transfer capability.
