Sydney Metro West will deliver a new direct, 24-kilometre underground rail connection between the CBDs of Parramatta and Sydney. 

The alignment will include stops at:

• Westmead
• Parramatta
• Sydney Olympic Park
• North Strathfield
• Burwood North
• Five Dock
• The Bays Precinct
• Pyrmont, and
• Sydney CBD.

The package of works for Line Wide Systems package comprises

• construction and commissioning of 24 kilometres of linewide rail and systems infrastructure 
• delivery of 60 kilometres of track, and 
• construction of a stabling and maintenance facility at Clyde, an operations control centre and the rosehill service facility.  

The Government of South Australia is duplicating Main South Road from Seaford to Sellicks Beach and Victor Harbour Road between Main South Road and the McLaren Vale turn off. 

Details of the projects are as follows: 

Main South Road Duplication

• Stage One - 10 kilometres of Main South Road from south of Griffiths Drive in Seaford to Aldinga. This will include the duplication of the Pedler Creek Bridge at Seaford Rise.
• Stage Two - will include a ‘2+1’ lane road layout for approximately six kilometres from Aldinga to Sellicks Beach. This will also include grade separations and road alignments at Aldinga Beach Road and Aldinga Road, and overtaking lanes between Myponga to Cape Jervis.

Victor Harbour Road Duplication

• Stage One - five kilometres between South Road at Old Noarlaunga and Main Road at McLaren Vale. 
• A planning study for the second stage of the duplication between McLaren Vale and Wilunga Hill is being undertaken. 

The Phoenix Pumped Hydro facility, being developed by ACEN Australia, is a proposed hydroelectric facility located near Wellington, in the Central West Orana Renewable Energy Zone. The proposed facility would have a capacity of 800 megawatts / 11,990 megawatt hours of storage capacity.

The Western Sydney Pumped Hydro (WSPH) is a project proposed by ZEN Energy to repurpose a disused coal washery site on the eastern side of Lake Burragorang, approximately 24 kilometres upstream from the Warragamba Dam wall. 

The WSPH project has a proposed one-gigawatt / eight-gigawatt hour capacity.

The Great Western Battery involves the installation of a 330-megawatt / 3.5-gigawatt hour battery at Wallerawang in NSW. The project is being developed by Neoen and will use existing network infrastructure near the decommissioned Wallerawang Power Station to connect to the national grid.

The project includes the construction of battery enclosures, inverters, transformers, a transmission line connection to the existing Wallerawang sub-station and is separate to the Wallerawang Battery which is located in the same area.

The Battery will aim to provide Fast Frequency Response services to the National Electricity Market and act as a reserve to augment power supplies in the Central-West Orana Renewable Energy Zone. 

The proposed 100-megawatt / 1,080-megawatt hour Kingswood Battery Energy Storage System (BESS) is located approximately six kilometres southeast from Tamworth.

The project is proposed by Iberdrola.

FRV Services Australia have proposed the Armidale East BESS, a battery project with a 158-megawatt (MW) / 1,440-megawatt hour (MWh) capacity. The project will be located approximately 16 kilometres east of Armidale, within the Tamworth Regional Council area and the New England REZ. 

Construction of the BESS would include the following key components: 

• 158-MW /1,440-MWh BESS including:
  • battery containers
  • inverters
  • transformers
  • cooling systems if required
  • fire suppressions systems
  • switch rooms
• an onsite substation
• switch yard
• new access road to the site, and
• parking site, site office and amenities for operational use.

The BESS would connect to the National Electricity Market via the overhead TransGrid north-running 330-kilovolt transmission line, which feeds into the Armidale substation and will connect directly into the Project via overhead cabling.

The Bowmans Creek Wind Farm is a proposed wind generation and battery storage project located 10 kilometres east of Muswellbrook, in the NSW Hunter-Central Coast Renewable Energy Zone.The project has been proposed by Ark Energy.

The project is expected to be delivered across two stages:

• Stage One: installation of 54 wind turbines and battery energy storage system with a capacity of 250 megawatts / 2,414 megawatt hours, and
• Stage Two: installation of 21 wind turbines.

• Stage One: installation of 54 turbines with a generation capacity of 335 megawatts (MW) and supporting infrastructure.
• Stage Two: an additional 21 wind turbines delivering 120 MW of generation, bringing the project's total generation to 455 MW.

The project includes 14 kilometres of overhead and seven kilometres of underground, 330-kilovolt transmission lines to connect to TransGrid’s existing Liddell substation.
