Cumulative pressure by REZ
This is a decision-support signal, not a scientific final score. Pressure bands combine project concentration, overlapping construction windows, workforce demand, accommodation availability, OSOM transport concentration and known local stress. Where data is missing, the field shows unknown rather than guessing.
Indicative projects likely under construction in each year, by REZ. Built from current project status and publicly stated proponent timelines where known. Not a forecast.
Read this carefully: the chart shows how many projects across NSW REZs are likely to be under construction in the same year. Even allowing for staggered starts and conservative window estimates, 2027 and 2028 cluster around 10+ projects concurrently across just two REZs (CWO and SW). That is the cumulative-pressure window. Projects in earlier stages (scoping, investigation area) are not yet in the window — if their planning advances on current timelines, the peak shifts later but does not flatten.
10 access-right projects (~7,151 MW headline capacity) concentrated in approximately four LGAs. Sum of proponent-stated construction workforce across five disclosed projects (Valley of the Winds ~400, Spicers Creek ~330, Tallawang ~420, Sandy Creek ~600, Pottinger context ~900): well over 2,000 construction roles, with construction windows likely overlapping in 2027-2029. Accommodation and OSOM transport are the most visible pressures. Workforce numbers are proponent-supplied; treat as indicative.
REZ Transmission Project and EnergyCo coordination provide some sequencing. Project-level workforce strategies and accommodation plans are typically required as conditions of approval. A precinct-level workforce accommodation strategy is recommended but not yet established.
6 access-right projects across four proponents totalling ~3.56 GW initial access (~5 GW full development). Pottinger alone is approved for up to 1.3 GW with ~900 peak construction roles. Yanco Delta is approved at 1.5 GW. Dinawan Energy Hub aggregates three points-of-connection in a small geographic footprint. Logistics interface with PEC Eastern Section operating infrastructure. Indicative construction workforce sum across approved SW REZ projects exceeds 2,000 roles; overlapping windows from 2027.
PEC NSW Eastern Section now operating reduces some delivery risk. Project-level workforce strategies expected. Coordination opportunities around shared logistics, port-to-site routes and rail aggregates from Victoria (Deniliquin via the Echuca-Deniliquin line) are not yet formalised at REZ level.
Predominantly investigation-area and early proposals; access rights not yet awarded. Cumulative impact estimates are speculative at this stage. Concentration risk depends on which projects progress through SEARs to EIS and which secure access rights.
Opportunity to set REZ-wide workforce, accommodation and benefit-sharing principles before access-right tenders run.
Hunter has existing energy workforce and accommodation infrastructure. Cumulative pressure interacts with coal-to-renewables transition workforce shifts. Just Transition considerations material.
Hunter Renewal Initiative and other regional transition frameworks provide existing coordination architecture.
Onshore Illawarra REZ is at an early stage; interface with the Commonwealth Illawarra offshore wind declared area is the dominant near-term consideration.
Port of Port Kembla emerging as offshore wind logistics hub; coordination with onshore REZ at planning stage.
- Does: surface where concentrated pressure is likely.
- Does: distinguish high-data signals from gaps (shows "unknown").
- Does: link to projects and shared value commitments.
- Doesn't: deliver a scientific quantitative score.
- Doesn't: substitute for project-level EIS social impact assessment.
- Doesn't: predict community sentiment or rate community groups.
