Grid Connection Services for Battery Energy Storage Systems (BESS) in Australia

Connecting a Battery Energy Storage System (BESS) to the National Electricity Market (NEM) is a complex, multistage process which requires deep technical expertise, rigorous modelling, and a clear understanding of AEMO and Network Service Provider (NSP) expectations and close engagement with them. Our team provides endtoend support through every step of the gridconnection journey from early feasibility through to energisation and R2 compliance.

End-to-End Grid Connection Expertise

We specialise and have a track record in navigating the technical and regulatory requirements that underpin successful BESS integration. Our services cover the full lifecycle of the connection process, including:

  • Prefeasibility and connection strategy
    Earlystage assessment of network constraints, connection options, and project risks to support investment decisions.
  • AEMO and NSP engagement
    Coordinated communication with AEMO and the local DNSP/TNSP to streamline the application process and address technical queries proactively.
  • Generator Performance Standards (GPS) development
    Preparation, negotiation, and refinement of GPS to ensure compliance with the National Electricity Rules (NER) while maintaining project viability.
