Australia risks alienating the public if the energy transition appears chaotic and subject to endless delays, says Felicity Galluzzo, Director of Power and Energy at WSP in Australia.
Australia’s swift shift towards a clean energy future is taking place on a foundation that was built for a much slower pace.
Our existing regulatory frameworks, grid connection requirements, and market rules are products of an era defined by gradual, prudent and incremental development. However, the current energy transformation is anything but gradual. It requires a seismic, system-wide leap.
Accelerating development doesn’t mean rushing through the status quo or taking shortcuts. Late design adjustments trigger fresh assessments, fragmenting approvals and compounding bottlenecks across an already stretched approvals process. A small change in a turbine hub height, a minor shift to a solar array layout or a little tweak to transmission cable routes might sound minor, yet every incremental edit can slow the whole system.
Despite Australia’s ambitious 2030 and 2050 climate targets fast approaching, the average approval timeframe for a utility-scale solar project has ballooned to over three years, while extending to more than four years for onshore wind developments.
The price of an inadequate upfront engineering and approvals strategy is more than just a slipped timeline; it threatens achieving our national climate objectives and erodes the public trust necessary for the transition’s success. To avoid this, we must integrate engineering disciplines holistically with planning, environmental and community engagement processes right from the inception of a project.
Bring engineering to the front of the queue
Too many projects attempt to lock down planning first and bolt on the technical detail later. This sequencing invites cost and schedule blow‑outs when conditional approvals collide with maturing designs.
The better path is to treat engineering models, grid studies and geospatial constraints as inputs to planning, not afterthoughts. As the design evolves, the approvals narrative should evolve with it so that change is manageable, transparent and faster to approve.
In practice, this means assembling multidisciplinary teams from the outset, including engineering, environment, digital and social licence, so trade‑offs surface early and are captured in a single, coherent information stream. When engineering leads early, approvals happen with fewer surprises.
Clarity that capital can bank on
Every late redesign, extra approval loop or unplanned fix inflates risk. Higher risk means larger contingencies, pricier finance and, at worst, deferred investment. The inverse is also true: clarity in the front end reduces uncertainty and tightens confidence around cost and schedule, which are all things investors will notice.
Two shifts matter:
- Integrated front‑end thinking reduces the probability and impact of change. Reconciling technical, environmental and community considerations upfront minimises any potential rework later.
- Confidence comes from clarity. When risks are identified, quantified and owned early, developers can present a credible story to investment committees, improving bankability and keeping capital flowing to projects that are genuinely ready to execute.
Digital acceleration without the theatre
Digital tools shorten the loop from question to answer. Work that previously consumed months, such as the manual analysis of multiple infrastructure corridor options or assessing layout sensitivities, can now be completed in a matter of hours. This digital acceleration allows for smarter, better-informed decision-making, as it facilitates the testing of more scenarios, clarifies project trade-offs and allows for live updates as input parameters inevitably evolve.
It’s about better decisions, made earlier, with evidence. Self‑serve screening, constraint mapping and change histories create auditable trails that speed internal governance and external approvals alike. The discipline is to invest digital effort where it most reduces risk, not where it merely looks impressive.
Policy that moves at the pace of delivery
While radical, wholesale policy overhauls can technically keep pace with our national ambition, the risk of constantly switching between rulebooks is that delivery can stall entirely as every stakeholder is forced to relearn how to operate. A more resilient approach is continuous, targeted improvement, using engineering to meet policy halfway.
To get there we need to align approvals with technical reality by creating single, coordinated pathways. Design change control protocols that will distinguish between genuine tweaks, and changes that would trigger wholesale reassessment before they hit the approval desk.
Environmental constraints should be integrated into the design from the beginning, not assessed after the fact. Building these constraints into engineering early helps avoid impacts, sharpen economics and reduce surprises in assessment. Good engineering anticipates community expectations; it doesn’t try to retrofit them.
We risk alienating the public if the energy transition appears chaotic and subject to endless delays. The answer is to identify and execute the right tasks earlier, performing them once or twice, rather than suffering through multiple iterations. By prioritising and mandating front-end engineering from day one, we can help future-proof Australia’s energy system, cultivating the capacity, the necessary financial confidence and the public permission required to keep moving forward.
The path ahead is undoubtedly complex, but it doesn’t have to be disorderly. Embedding smart engineering upfront is the vital mechanism that allows us to move quickly without destabilising the essential systems we all depend on.

The proposed transition of our electricity generation to solar, wind and batteries will be a total disaster. It will be an uncontrollable mess without conventional generation and hence without baseload power to maintain stable voltage and frequency and to ensure that supply always equals demand. There is also the risk where there will be too much supply and not enough demand, especially as it is recommended that we are being encouraged to massively increase our demand during the middle of the day.
