In newly revealed plans, Powercor is looking to speed up the connection of renewable energy projects and has proposed up to 20 large-scale energy storage projects with capacity of up to 1.1GW – significantly larger than anything in Australia today.
The plan has been proposed to the Victorian Government to unlock large-scale renewable generation faster and more simply via the distribution network, instead of an approach that relies wholly on connections to the transmission network.
The proposal seeks to unlock 1.3GW or capacity on the existing network and improve reliability for customers through a series of network upgrades over two stages, including:
- Synchronous condensers spread out across the network to deliver system strength that supports new large-scale renewable connections to both the transmission and distribution networks
- Upgrading key parts of the 66kV network to enable a greater number of large solar and wind projects to connect to the existing network within the Geelong, Shepparton, Terang, Ballarat and Bendigo regions
- Grid-scale batteries installed across up to 20 existing network sites in central, western and northern Victoria, delivering as much as 1.1GW of storage capacity to release transmission constraints while also providing local community benefits
Powercor’s proposal to the Victorian Government comes in response to the Victorian Government’s recently released Renewable Energy Zone discussion paper. Powercor’s network is home to four of Victoria’s six Renewable Energy Zones.
The proposal also complements the Victorian Government’s recent announcement of a 45-50 per cent emissions reduction target by 2050.
Powercor General Manager, Electricity Networks, Mark Clarke, said distribution networks should be considered as part of a whole-of-network solution to unlocking the targeted 10GW of new renewable energy capacity in the shortest time possible.
“Connecting renewable energy at the distribution network level is fast, simple and generates greater benefits more broadly spread out at the local level,” Mr Clarke said.
“The real opportunities come from creating jobs and network capacity that will benefit a large number of diverse communities.”
The Powercor proposal requires no new easements, and uses existing land and assets owned by Powercor to ensure no additional impacts on the visual amenity of communities or local agricultural or natural environments.
“We can support new renewable generation while also improving power reliability and network capacity for more solar, EV charging infrastructure and battery programs in local communities,” Mr Clarke said.
Already, 2GW of renewable energy generation is connected to the Powercor network, with another 2.3GW of active connection enquiries or applications ranging in size from 1MW to 150MW in the assessment process.
Mr Clarke said having comparatively smaller projects connected via the distribution network meant more projects could be built at the same time, leading to more jobs for regional Victoria.
“There were more than 300 people, mostly locals, employed during the construction of the 112MW Karadoc Solar Farm in north-western Victoria, which is connected to the Powercor network,” Mr Clarke said.
“Many of these employees and apprentices have now gone on to use that experience and those skills to build careers on other renewable generation projects around Australia.”
