Solar and renewables for installers / RECs

Jemena and all other distribution networks must submit embedded generation (i.e. rooftop solar) details to a register known as the Distributed Energy Resources register, or ‘DER’. The DER is a centralised data set for each residential and commercial embedded generation installation, which will allow networks to make better informed decisions about network investment options, and allow AEMO to forecast, plan and operate the grid more efficiently.

To ensure all required information is captured and sent to AEMO, Jemena has an online Embedded Generation application which aligns the capture of Jemena’s solar and renewables data with all other construction applications in our ‘Connect and manage my electricity’ portal.

This application must be completed prior to a request to the customers retailer requesting the meter be reconfigured to record solar generation. Creating this application auto-generates a unique installation reference number, known as the Embedded Generation application ID, or ’EGid’. The EGid is used by Jemena, AEMO and the retailer for reference throughout the configuration process.

Information for customers

For residential and commercial customers looking to install solar and renewables:

When customers are ready to have their solar / renewable power connected to the grid, they must provide the following information to their energy retailer:

i.     EGid - Embedded Generation application ID
ii.    EWR - Electrical Works Request
iii.   CES - Certificate of Electrical Safety

Customers are encouraged to ensure they obtain this information from their installer / REC once their solar panels are installed and the Embedded Generation application has been submitted.

Information for installers and electrical contractors

1.    Changes to the Embedded Generation form

All installers and electrical contractors are required to:

i.    enter all required information directly into the Embedded Generation application on the Jemena ‘Connect and manage my electricity’ portal. This online application is mobile enabled, allowing data to be entered on the go; and
ii.    provide additional information in the application than has traditionally been required by Jemena. This will involve the completion of 17 fields of data relating to the devices being installed, as per the checklist below.The following table shows the new Jemena process for embedded generation applications.

Embedded Generation Application data checklist:

DER Installation Fields AC Connection Fields DER Device Fields
Aggregated Approved Capacity (kVA) Number of AC Connections Number of DER Devices
Installer Identification AC Equipment Type Device Type
Number of Phases Available Inverter/Small Generating Unit Manufacturer Device Sub Type
Number of Phases with DER installed Inverter Model Number Manufacturer
Does the inverter have voltage response modes (Volt-Var & Volt-Watt)? Inverter Series Model Number
Comments Serial Number  
National Meter Identification Number    

 

The following table describes the new Digital process.

2.    Changes to the MSO Standards

The inverter standards in our Model Standing Offer are now also aligned with those of other Distributors across Victoria. This includes a revision of the connection agreement for small generators, which now requires inverters to be capable of both volt-watt and volt-var control modes. The revised power quality response modes are shown below:
