Embedded generation is the term used to describe the process of generating electricity at a specific location and then connecting that supply into the electricity network.
There are a number of different generator types that can be connected to the distribution network. These may include:
Open and closed cycle gas turbines
Reciprocating engines (diesel, oil)
Photovoltaic generation (solar)
Generation sources such as fuel cells and photovoltaic installations generate DC (direct current) electricity and must be connected to the distribution network via an inverter. The inverter converts the DC-generated output to alternating current (AC) so the generated energy can be exported into the network.
The National Electricity Rules and the National Electricity Retail Rules prescribe the processes for making new connections, or altering existing connections to our distribution network.
There are different processes for embedded generators (generators that export energy into the distribution network) and loads (electrical installations that take power from the distribution network).
Small and micro embedded generators may elect to go through an enquiry stage. However, this removes them from the 10 business day expedited connection process.
Micro embedded generators including solar
Micro generators include solar and are smaller than 10kW per phase. They connect to the distribution network through an AS4777-compliant inverter.
Small embedded generators
Small generators are less than 5MW, connected to the distribution network, that are not classed as micro generators.
Large embedded generators
Large generators are connected to the distribution networks and are either greater than 5MW or less than 5MW and are registered with the Australian Energy Market Operator.
