The Middlebrook Solar Farm is a proposed 320-megawatt (MW) solar farm and battery storage system located approximately 20 kilometres south of Tamworth. The project will be located between, but outside of, the New England and Hunter-Central Coast Renewable Energy Zones.

The project scope comprises construction of:

• a 320-MW solar farm comprising 750,000 solar panels
• a 320-MW / 780-megawatt hour Battery Energy Storage System
• an onsite 330-kilovolt substation, and
• other associated infrastructure.

Cross River Rail will provide an additional rail crossing across the Brisbane River.

The project involves:

• a new 10.2-kilometre rail line from Dutton Park to Bowen Hills
• 5.9 kilometres of twin tunnels under the Brisbane River and CBD
• four new high-capacity underground stations at Boggo Road, Woolloongabba, Albert Street and Roma Street
• eight rebuilt above-ground stations at Salisbury, Rocklea, Moorooka, Yeerongpilly, Yeronga, Fairfield, Dutton Park and Exhibition
• three new stations on the Gold Coast, and
• a new signalling system: the European Train Control System (ETCS).

The Cross River Rail project is being delivered through three major infrastructure packages of work:

• the Tunnel, Stations and Development (TSD) package (awarded to the Pulse Consortium through a Public Private Partnership)
• Rail, Integration and Systems (RIS) package (awarded to the Unity Alliance through an alliance contract), and
• the ETCS package (awarded to Hitachi through an alliance contract).

The Gippsland Offshore Wind Transmission Project will support the connection of offshore wind infrastructure in the Gippsland Offshore Wind Zone to the mainland grid. The project will run from a new connection hub on the mainland near the Gippsland coast, which will service offshore wind farm connections, to a grid connection point near Loy Yang Power Station. 

The proposed project comprises the development, construction and operation of approximately:

• 55 kilometres of 500-kilovolt transmission lines
• an onshore connection hub, including high-voltage substation plant and equipment, and
• a grid connection substation near the Loy Yang Power Station.

The project was formerly known as the Greater Gippsland Transmission Project.

The Byford Rail Extension is an eight-kilometre extension of the Armadale line from Armadale Station to Byford and includes:

• a new ground-level Byford Station with approximately 400 parking bays
• elevated rail through Armadale, with a new elevated Armadale Station, and
• removal of eight level crossings at Armadale Road, Forrest Road, Church Avenue, Seventh Road, Byron Road, Eleventh Road, Thomas Road and Larsen Road.

The CopperString 2032 project, formerly known as CopperString 2.0, initially involves building 840 kilometres of new electricity transmission line from south of Townsville in the Burdekin region to Mount Isa that will connect Queensland’s North West Minerals Province (NWMP) to the National Electricity Market.

The CopperString project comprises the delivery of:

• 330-kilovolt (kV) transmission line from just south of Townsville to Hughenden (Eastern Link)
• 330-kV transmission line from Hughenden to Cloncurry
• 220-kV transmission line from Cloncurry to Mount Isa
• up to six new substation sites, and
• workforce accommodation and facilities in strategic locations along the corridor.

The project is being led by the Queensland Investment Corporation (QIC). Powerlink was previously delivering the project prior to QIC's review in October 2025.

The Bundey BESS and Solar Project is a proposed 900-megawatt (MW) solar farm and 1.2-gigawatt / three-gigawatt hour battery, located northeast of Robertstown, South Australia.

The project is proposed by Genaspi Energy Group.

The Bell Bay Wind Farm is a proposed 224-megawatt (MW) wind farm and 100-MW / 400-megawatt hour battery, located in George Town, Tasmania. The project includes the construction of a substation and switchyard southwest of Beechford, access roads, office and works

The project is proposed by Equis.

The Hexham Wind Farm is a proposed 686-megawatt wind farm located near Hexham, Victoria. The project includes:

• an onsite connection to the existing overhead 500-kilovolt transmission powerline via a new terminal station
• installation of overhead powerlines and underground electrical cabling
• a battery energy storage facility (no indicative size has been announced), and
• supporting infrastructure.
