Jemena and all other distribution networks must submit embedded generation 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.
What does this change mean?
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.
For our 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.

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:
