Concentrated Solar Thermal: Request for Information


The Australian Renewable Energy Agency (ARENA) is seeking industry information as the first step in exploring how concentrated sunlight could generate reliable, affordable renewable energy with built-in storage for our national grids.

The new call aligns with the Federal Government’s offer to make up to $110 million available for an equity investment to accelerate and secure delivery of a CST project in Port Augusta.

We are inviting all interested stakeholders to have their say before the end of July.

Request for Information

ARENA is requesting information from prospective industry participants on the costs and benefits of Concentrated Solar Thermal (CST).

This information will help ARENA and the Clean Energy Finance Corporation (CEFC) to determine the scope and focus of government assistance for the deployment of CST in Australia.

Interested parties are expected to include (but are not limited to) project proponents, debt and equity investors, original equipment manufacturers, off-takers and government entities.

Responses are due by 5pm 31 July 2017, can cover all types of CST technology and project sizes, and should not exceed a written submission of 20 pages.

Respondents should outline:

  • the nature of their interest in CST (for example as an investor, developer, technology provider, off-taker, regulator
    their experience with CST
  • their view of CST’s potential value proposition relative to other renewable generation technologies
  • any preferences with respect to firm generation profile and potential value uplift for that purpose
    regulatory, commercial, market or technical barriers and opportunities facing CST
  • environmental considerations in CST deployment
  • their views of the key risks in CST projects and how they might be best mitigated
  • preferred energy and renewable energy certificate offtake arrangements
  • factors differentiating such projects from other technology solutions, and
  • any other information the respondent feels may be relevant to the ARENA and CEFC’s consideration as to how best to support the deployment of CST.

Where respondents are considering potential roles as CST project developers or contractors respondents are invited to outline their views of:

  • the optimal maximum and minimum CST project sizing (rated capacity, storage hours), location and dispatch profile
  • the expected capital and operating costs of deploying the optimal project
  • expected areas of future capital and operating cost reduction (local and international replication) by, for example:
    • anticipated technology improvements
    • anticipated capital cost reductions
    • potential to develop the local supply chain
    • future labour savings and risk margin savings in delivery
    • expected local content and the potential for local industry development
    • expected annual energy output
    • likely construction and commissioning timeframes, and
    • potential grid impacts.

Information will be treated in accordance with ARENA’s Advancing Renewables Program Guidelines, however some information may be publicly disclosed after it has been aggregated and anonymised.

Responses are due by Friday 31st July 2017 at 5pm
