Pilbara Electricity Networks

Summary

On 7 November 2022, the ACCC received an application from Pilbara ISOCo Limited (the Applicant) who is the independent system operator (ISO) for the North-West Interconnected System (NWIS), an electricity grid in Western Australia’s Pilbara region. The Pilbara Regime is a specialist regulatory regime created by the Western Australia government to cover access and use of certain covered electricity networks in the Pilbara region. The Applicant was incorporated to perform the ISO role for the Pilbara Regime. The Pilbara Regime gives the ISO and various other persons powers and responsibilities in order to:

  • facilitate access to the covered networks in order to promote competition in the generation and supply of electricity, and
  • provide for the integrated operation of the various networks to maintain and power system security and reliability.

Authorisation is sought by the Applicant on behalf of itself and three separate classes of current and future persons with powers and responsibilities under the Pilbara Regime to engage in any conduct that is required or permitted by the Pilbara Regime to allow for its implementation and facilitation.

Specifically, the conduct relates, but is not limited, to:

  • the Applicant’s centralised procurement and allocation of essential system services and payments
  • the Applicant’s management of the centralised energy balancing regime and payments
  • the Applicant’s procurement of whole-of-system modelling services
  • the National Service Provider’s and the Applicant’s approval of new connections
  • the National Service Provider’s and the Applicant’s management of constrained access
  • the National Service Provider’s and the Applicant’s operational decisions, directions actions and protocols
  • the National Service Provider’s various collaboration and coordination, with and without the Applicant
  • the Applicant’s delegation of its real-time control desk function to Horizon Power, and
  • information sharing between National Service Providers and the Applicant.

Authorisation is sought for a period of 10 years.
