Welcome to ETSA Utilities' Guide to Embedded Generation Network Connections. The term 'embedded' applies to both small and large-scale generators connected to the ETSA Utilities distribution network.
Small Embedded Generators are defined for the purpose of the Guide as embedded generator installations complying with the relevant Australian Standard AS 4777 (grid connection of energy systems via inverters), Parts 1, 2 & 3. For installations complying with AS 4777 with grid connected inverters, we will connect single phase installations up to a maximum of 10 kVA and three phase installations up to a maximum of 30 kVA.

Large Embedded Generators are defined for the purpose of the Guide as all other embedded generator installations not covered by the requirements of the relevant Australian Standard AS4777 (grid connection of energy systems via inverters). Large Embedded Generator installations, whether export or non-export, connected to operate in parallel with the ETSA Utilities network, must be assessed by us for suitability for connection and comply in all respects to the Guide.
