Grid Connection Studies

Grid Connection Studies

Getting a renewable energy project connected to the Australian grid is one of the most technically demanding and commercially critical phases of project development. ElectraGlobe manages the full grid connection process, handling the technical complexity on your behalf and keeping your connection timeline on track.

Our grid connection services cover the full application process with all distribution and transmission network service providers across Australia, from preliminary feasibility through to Dynamic Model Acceptance Testing.

What Are Grid Connection Studies?

Grid connection studies are the technical analyses required to assess how a new generator or storage system will interact with the existing electricity network at the proposed connection point.

The Core Studies

  • Power flow analysis: steady-state voltages, thermal loading and power transfer at the connection point
  • Fault level assessment: short circuit contribution and equipment fault rating adequacy
  • Protection coordination: grading, settings and network protection unit configuration
  • Dynamic stability: system response to faults, disturbances and network events
  • Voltage regulation: voltage rise, step change and reactive power capability

These studies form the technical basis of your connection enquiry and must satisfy the requirements of the relevant network service provider before an offer to connect is issued.

What ElectraGlobe Delivers

Our scope is set by the stage your project is at and by how much of the connection work your internal team already covers.

Network Service Providers We Work With

We have established working relationships with all major NSPs across Australia.

StateNetwork service providers
NSWAusgrid, Essential Energy, Endeavour Energy
VICPowercor, CitiPower, United Energy, AusNet Services, Jemena
QLDErgon Energy, Energex
SASA Power Networks
TASTasNetworks
WAHorizon Power, Western Power
ACTEvoenergy

Each provider sets its own technical requirements, submission formats and review timelines, and knowing them before the enquiry is lodged is what keeps a connection on programme.

If you have a site under assessment or an enquiry already with an NSP, we can tell you quickly where the technical risk sits and what the connection path looks like.
