With more Victorians embracing community batteries, solar gardens and other types of distributed energy resources, making network data accessible to a broader audience is an important step for the energy transition.

This site provides a selection of resources which respond to requests received from a diversity of project proponents, local governments and new energy service providers.

Please note that all information accessible here is general in nature. It suits projects at an early stage of planning such as information gathering, options definition or pre-feasibility stages.

Once you have developed a project scope and plan and need a connection agreement, visit our eConnect online service to submit a connection application. More detailed network data requests relevant to your specific project will then be managed as part of this request.

Network Visualisation Portal

This geographical map contains multiple layers of information about the location of our distribution network assets and opportunities to support the network. 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.

Its release follows extensive testing and development of a similar mapping tool in 2022 following our Electric Avenue Feasibility Study.  This identified the need for a permanent solution that meets the rising demand for network data to help various organisations.  Some of the reasons for the data sought included:

• planning for targeted solar promotions
• planning for third-party owned neighbourhood batteries
• supporting academic research into new energy solutions
• identifying suitable sites for distributed energy resources including large-scale renewable generation
• offering demand management or voltage services.

We will update the data available at least annually and also plan to use the Network Visualisation Portal to highlight future network support tenders.

A future version of the portal will also provide constraints data and demand forecasts for distribution substations on the low voltage network.

We welcome all feedback to improve the portal. Send us an email to community@powercor.com.au.

Distribution network planning

The Distribution Annual Planning Report (DAPR) for CitiPower and Powercor 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 – including CitiPower and Powercor.

DAPR and TCPR documents

Regulatory Investment Tests for Distribution

A Regulatory Investment Test for Distribution (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.

Register of completed embedded generation projects

This register of completed embedded generation projects has been developed to improve the level of technical information available to interested parties on generators that have been successfully connected to both the CitiPower and Powercor distribution networks. Completed embedded generation projects will only be named if their project information is publicly available as part AEMOs generator registrations process, applicable to generator projects >5MW.

Zone substation data

We also make available historical load data on a Zone Substation level. This raw data is provided in a CSV format only. If you would like further access to information, please select the relevant report:

Demand Side Engagement Strategy

CitiPower and Powercor provide a Demand Side Engagement Strategy to assist non-network providers in understanding our framework and processes for assessing demand side options. This engagement strategy also discusses our consultation process with non-network providers.

As consumers generally continue to require more electricity to meet their needs, nonnetwork providers are having an increasingly important role in the supply of electricity. Where technically feasible and economic, non-network options can help to address localised constraints in the network and thus defer network augmentation. As such, non-network options have the potential to meet rising demand at a lower cost to consumers.

This strategy provides information on how CitiPower and Powercor will engage with non-network providers and how it will consider non-network options.

Consumption data

This report provides information on the amount of electricity consumed at both postcode and Local Government Area (LGA) levels in the CitiPower and Powercor regions. 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 2016 and provides information on a monthly and yearly basis. This will be updated every 6 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.

If you can’t find what you’re looking for, you can request network data from CitiPower Powercor. We’ll need your contact details and the purpose of your request, so we can ensure that the correct data is provided.
