Project Overview

We are proposing to replace 26 circuit breakers at 11 substations to maintain safe and reliable electricity supply to customers.

The identified need for this project is to continue to provide safe and reliable electricity transmission services in South Australia at a prudent and efficient cost. Specifically, the identified need for this Regulatory Investment Test for Transmission (RIT-T) is to efficiently manage the risk of failure of circuit breakers across 11 substations that are in poor condition and have reached the end of their technical lives.

We have classified this RIT-T as a ‘market benefits’ driven RIT-T as it is being progressed to manage the risk of asset failure and thereby deliver positive net benefits to customers.

A full cost benefit assessment has been undertaken, comparing the risk cost reduction benefits of circuit breaker replacement with the cost of a base case ‘do nothing’ option, together with options considered but not being progressed.
