Definition: A Project Specification Consultation Report (PSCR) is the first formal public document produced by a transmission network service provider (TNSP) in the Regulatory Investment Test for Transmission (RIT-T) process. It describes the identified network need or problem, outlines a range of credible options for addressing that need — including both network and non-network solutions — and invites stakeholder feedback before the full cost-benefit analysis is undertaken. The PSCR is the RIT-T’s opening statement to the market and the community.
What is the Purpose of the PSCR?
The PSCR serves as the foundation of the entire RIT-T process. Before a TNSP can commit to a preferred investment option, it must first clearly define the problem it is trying to solve and canvas the full range of possible solutions. The PSCR does exactly that — it frames the assessment and invites early, substantive input from stakeholders who may have expertise, local knowledge, or alternative perspectives that could improve the quality of the analysis.
The PSCR ensures that the RIT-T is not a rubber-stamping exercise for a decision already made internally. By publishing the problem statement and options before the cost-benefit analysis is finalised, the PSCR gives generators, retailers, large consumers, community groups, and other market participants a genuine opportunity to shape both the scope and the methodology of the assessment.
What Does a PSCR Contain?
A well-prepared PSCR will typically include:
- Description of the identified need — a clear articulation of the network problem or gap being addressed, including the technical or market drivers (e.g., forecast reliability shortfall, export constraint, new load connection requirement)
- Demand and generation outlook — projections of future electricity demand and generation in the relevant area, drawing on AEMO’s forecasts and the TNSP’s own network planning analysis
- Network context — a description of the existing network configuration and its limitations in addressing the identified need
- Credible options — a list and description of all options considered capable of addressing the identified need, including:
- Network augmentation options (new lines, cables, substations, or upgrades)
- Non-network options (demand response, battery storage, generation investment, virtual power plants)
- The “do nothing” or base case option
- Assessment methodology — an explanation of how costs and benefits will be quantified and compared, including modelling tools, assumptions, and the discount rate to be applied
- Indicative timeline — a high-level schedule for the RIT-T process, including the expected timing of the PADR and FPAR
- Invitation for submissions — a clear call for stakeholder feedback, with details of how and by when submissions should be lodged
PSCR in the RIT-T Process
The PSCR is the first of three key public documents in the RIT-T process:
| Stage | Document | Purpose |
|---|---|---|
| 1 | Project Specification Consultation Report (PSCR) | Defines the need and options; invites early stakeholder input |
| 2 | Project Assessment Draft Report (PADR) | Presents cost-benefit analysis and preferred option; invites submissions |
| 3 | Final Project Assessment Report (FPAR) | Confirms preferred option; responds to submissions; concludes the RIT-T |
The PSCR is published before the detailed cost-benefit modelling is completed — meaning that stakeholder input at this stage can still meaningfully influence which options are assessed, what assumptions are used, and how the analysis is structured. This makes the PSCR consultation period one of the most strategically important points in the entire RIT-T process for interested parties.
Who Should Engage at the PSCR Stage?
The PSCR consultation process is open to all interested parties. Those with the most to gain from early engagement typically include:
- Existing and prospective generators — particularly those whose projects may be affected by, or could serve as alternatives to, the proposed network investment
- Large industrial customers — including mining companies and industrial facilities whose electricity costs are directly affected by transmission network charges
- Demand response and storage providers — businesses offering non-network solutions that could address the identified need at lower cost
- Local governments and communities — particularly those in areas where new transmission infrastructure is proposed
- Environmental and conservation groups — who may wish to flag environmental sensitivities relevant to the options under consideration
- Energy retailers and market analysts — who can contribute to the assessment of market benefit methodologies and assumptions
The Importance of Non-Network Solutions in the PSCR
One of the most significant features of the PSCR stage is its requirement to identify and assess non-network solutions alongside traditional network investment. This reflects a core principle of the RIT-T — that building more wires and substations is not always the most efficient way to solve a network problem.
Non-network solutions that might be identified in a PSCR include:
- Battery energy storage systems (BESS) — which can provide peak capacity, frequency response, and network support without new transmission infrastructure
- Demand response programs — which reduce consumption at peak times, deferring or avoiding the need for network augmentation
- Embedded generation — new generation located within the constrained area, reducing the need to import power over congested lines
- Virtual power plants (VPPs) — aggregated networks of distributed energy resources that can collectively provide network support services
By explicitly canvassing these options in the PSCR, the RIT-T ensures that the cost-benefit analysis considers the full range of available solutions — not just the transmission network’s default preference for capital-intensive infrastructure.
PSCR vs. Other RIT-T Documents
It is worth understanding how the PSCR differs from the other documents in the RIT-T process:
| PSCR | PADR | FPAR | |
|---|---|---|---|
| Stage | First | Second | Third and final |
| Content | Problem and options | Cost-benefit analysis | Confirmed preferred option |
| Modelling complete? | No | Yes | Yes |
| Consultation | Yes | Yes | No (AER review only) |
| Can change options? | Yes — new options can be raised | Limited — focus is on analysis | No |
The PSCR is therefore the most open and flexible stage of the process — the point at which the broadest range of input can be incorporated into the assessment.
Real-World Relevance: CopperString 2032
For the CopperString 2032 Project, the PSCR process was an important early step in establishing the economic case for connecting the North West Minerals Province to the NEM. As Powerlink Queensland worked through the RIT-T, the PSCR provided the formal framework for:
- Articulating the network need — the absence of any grid connection to North West Queensland and the consequent reliance on expensive, carbon-intensive diesel generation
- Identifying the range of options — including different transmission route options, voltage configurations, and potential non-network alternatives
- Inviting market input — from mining companies, renewable energy developers, and other stakeholders with a direct interest in the project’s design and economics
The rigour applied at the PSCR stage helped establish the foundation for a cost-benefit analysis capable of justifying one of the largest regulated transmission investments in Australian history.
Key Takeaway
The Project Specification Consultation Report is the starting point of the RIT-T’s economic assessment process — the document that defines the problem, opens the options, and invites the market to participate before any investment decision is made. For energy developers, large consumers, non-network solution providers, and community groups, engaging substantively at the PSCR stage is one of the most effective ways to influence the outcome of a major transmission investment process.
