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 end-to-end support through every step of the grid connection 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.
