Project Description

The Port Augusta Renewable Energy Park Stage 2 project is a hybrid renewable energy power station comprising a solar photovoltaic (PV) farm with an installed capacity of up to 500MW(AC), one or more battery storage facilities of up to 400MW(AC) capacity and one or more synchronous condenser facilities providing up to 3000MW.s of real inertia.

The solar PV component of the project, covering an area of up to 880 hectares will be situated to the eastern side of the Augusta Highway, approximately 12km east-southeast of Port Augusta, and directly opposite Port Augusta Renewable Energy Park Stage 1.

The battery storage and synchronous condenser facilities will be located either adjacent to the Stage 1 substation, west of the Augusta Highway, or adjacent to the Stage 2 substation, east of the Augusta Highway, or both depending on final detailed design considerations.

The Project is located entirely within the Port Augusta City Council local Government area and has a predicted life of approximately 25 years, after which time it will either be decommissioned and remediated, or repowered with new equipment.

Current Status

DP Energy submitted a Development Application South Australian State Commission Assessment Panel in December 2017. This application is currently being assessed.

Construction

Project Construction

It is envisaged the Project will be built in seven overlapping phases.

Major construction activities undertaken will include:

  • Site preparation and clearing
  • Building the solar PV site tracks
  • Installing racking
  • Installing inter-array cabling
  • Installing solar modules
  • Building a substation/control room
  • Building the energy storage facility
  • Building the synchronous condenser facility
  • Installing overhead and/or underground export connection


Benefits

Economic Benefits

The Port Augusta Renewable Energy Park Stage 2 is a project of public infrastructure with significant public benefit as outlined below:

  • Construction will flow from Stage 1, targeting a continued use of workforce from the Stage 1 construction bringing continued benefit to the local community and reducing remobilisation costs;
  • It will increase employment opportunities in the mid-north of the state, an area which has recently seen a significant reduction in economic activity:
    • The first phase of the project (100MW of solar PV) will generate approximately 300 jobs during the construction phase; and 4 ongoing for the solar operation and maintenance jobs.
    • The storage component will generate approximately 8 jobs during the construction phase; and 2 ongoing for the storage operation and maintenance jobs.
  • It will provide a large dispachable renewable generation source which will act to help stabilise the electricity network at Davenport Substation and thereby offsetting the effect of the closure of Northern Power Station; and
  • It will provide an additional local landowner with a drought-proof income stream.

Environmental Benefits

When operational, the project will contribute to the South Australia’s Renewable Energy Target of 50% by 2025, the National Renewable Energy Target of 33,000GWh by 2020, and improved environmental outcomes through reduced greenhouse gas emissions.

Decommissioning

The project should be in operation for approximately 25 years following which there are two likely scenarios:

  • The site would be decommissioned and returned to its former condition. Major equipment including solar panels, energy storage components, and substation components would be broken up and recycled. Where possible existing tracks would be left in situ for use by the landowner;or
  • Reflecting the advances in technology, existing equipment would be replaced with the latest technology (within the existing development envelope).
