PWC Technical Audit 2017: Follow Up from the 2014 Audit reports on an audit of PWC (System Control Chapter 2 and Networks Chapter 4) and Territory Generation Chapter 3. The audit had a particular focus on improvements made since the system black in 2014. 

Power and Water Corporation Technical Audit 2017: Spinning Reserve is a report on the Commission’s review of technical issues relating to spinning reserve.

Technical Audit Summary

In 2014, the Commission audited Power and Water Corporation (PWC) in relation to a system black in the Darwin-Katherine power system. In 2017, the Commission conducted a follow-up audit on PWC’s business units, System Control and Networks, and Territory Generation. The audit finds there have been significant positive technical improvements in each entity. For example, all areas previously found to be non-compliant have improved to be either partially or fully compliant. 

The follow-up audit has demonstrated to the Commission that the individual entities now have a stronger focus on, and understanding of, their key regulatory obligations and responsibilities. This stronger focus has resulted in improvements in licencing and technical compliance by the three entities that were the subject of the follow up audit.

Spinning Reserve

Complementary to the technical audit, the Commission also reviewed issues of spinning reserve. Procurement of such services from electricity entities are required to maintain the continuous supply of electricity from the power system.

The Commission found System Control is generally compliant with the relevant regulatory requirements in the way it calculates and applies the spinning reserve calculation methodology.
