Network data

Please note that this information is general in nature. It suits projects at an early stage of planning such as information gathering, pre-feasibility or feasibility stages. Once you have developed a project scope and plan and need a connection agreement, visit myEnergy to submit a connection application.. More detailed network data requests relevant to your specific project will then be managed as part of this request.

If you can’t find what you’re looking for, you can request network data via our network data request form on myEnergy. You'll need to provide your contact details and the purpose of your request, so we can ensure that the correct data is provided.

Piclo Flex: online flexibility marketplace

Access to network data is critical to the development of non-network solutions. To improve visibility of constraints on our network, we’ve partnered with UK technology company, Piclo Energy, to develop a cloud-based flexibility marketplace.

Using it is simple – all you need to do is register your asset, wait for new competitions to be released in your area and submit your bid all in the same easy-to-use platform.

Network Visualisation Portal

This geographical map contains multiple layers of information about the capacity of our distribution networks. These layers provide:

• constraints on sub-transmission lines, zone substations and high voltage feeders, which are opportunities for demand management
• high voltage network maps illustrating the locations of the sub-transmission network, zone substations and high voltage feeders
• load trace data for zone substations
• network boundaries relative to Local Government Areas and postcodes.

When used with other network planning, and consumption data series available on this page, the portal allows more people to access opportunities on our networks.

Distribution Annual Planning Report (DAPR) and Transmission Connection Planning Report (TCPR)

The Distribution Annual Planning Report (DAPR) provides an overview of the current and future changes we propose to undertake on the network. The information contained relates to both the current year and five year forward planning including forecasts, system limitations, projects and investments.

The Transmission Connection Planning Report (TCPR) document sets out a joint report on transmission connection asset planning in Victoria, prepared by the five Victorian electricity Distributors.

Regulatory Investment Test for Distribution (RIT-D)

A RIT-D establishes consistent, clear and efficient planning processes for distribution network investments in the national electricity market.

Distribution businesses must assess applicable network investments under the RIT-D.

Network voltage reports

Effective voltage management is critical for integrating all forms of distributed energy resources into our networks.

Our network voltage reports are submitted quarterly to the Essential Services Commission and the reports published here summarise the data provided.

Zone substation data

We make historical load data available on a zone substation level. This raw data is provided in a CSV format.

Consumption data

This report provides information on the amount of electricity consumed at both postcode and local government area*. We receive requests for this data from time to time, particularly to support community-based energy projects and industry research and are pleased to make it freely accessible.

The time series commences from 2019 and provides information on a monthly and yearly basis. This will be updated every six months in February and August each year.

Data is provided on three customer categories – residential, commercial and solar. To protect the privacy of our customers, only aggregated information is provided. For more on how we protect the interests of individual customers, please see our privacy policy.

*Please note that we are reviewing the solar customer data as part of our quality assurance process. We will post updated information as quickly as possible. In the meantime, you can rely on all other information being accurate.
