Coverage
This page shows which sectors, facilities and national accounts we have analysed, and how deeply we examined each one.
Depth
A profile reconstructs one operation’s energy use, fuel, emissions, production and costs. We check it against national data, rate each figure and list the information that is not publicly available.
| Sector | Profiles | Scope |
|---|---|---|
| Aluminium smelting | 4 | Every operating and recently closed primary smelter in Australia |
| Alumina refining | 6 | Every alumina refinery in Australia, including the closed one |
| Gold mining | 11 | Operations across WA, NT and Queensland — a sample, not the sector |
| Cement, lime and non-metallic | 5 | Clinker, lime, magnesia and pigment plants |
| LNG | 3 | Queensland coal-seam-gas trains and their power supply |
| Steel and ferroalloys | 3 | Both primary steelworks, plus a manganese alloy plant |
| Base metals | 3 | Copper-zinc, nickel laterite and a multi-metal smelter |
| Bauxite mining | 2 | Fleet-level analysis with national reconciliation |
| Oil refining | 2 | Both refineries still operating in Australia |
| Pulp and paper | 2 | Newsprint and packaging mills |
| Fertiliser | 2 | Ammonia and phosphate manufacturing |
| Remote power stations | 2 | Stations supplying off-grid industrial load |
| Chemicals | 1 | Titanium dioxide pigment |
| Coal | 1 | An operating export mine |
| Lead and zinc | 1 | A primary lead smelter |
| Food processing | 1 | Rendering and protein recovery |
Two sectors are covered exhaustively: every Australian aluminium smelter and every alumina refinery. That is what allows a national check — add the facility results, compare them with the official national total, and explain the difference. The other fourteen sectors are samples. They are wide enough to show how an industry uses energy, and they cannot support a national total, so none is claimed for them.
Across all sectors the profiles now hold 4,367 measured and derived quantities for 49 facilities, each carrying the evidence class it was read at and, where a figure could not be established, the gap that remains.
Breadth
Screening answers a narrower question across a whole population: which sites have a given exposure, and which do not. It is deliberately shallower than a profile, and it does not determine project size or confirm a grid connection. Where a layer reports a register value — a tenement holder, a cash balance, a lodgement date — the record also carries what that register does not settle.
| Layer | Population | Question answered |
|---|---|---|
| Mine onsite generation | 370 sites | Which mines generate their own power, on what fuel, at what scale band |
| Mine power station ownership | 88 mines | Who owns the station, whether a battery is already installed, when the contract ends |
| Commodity screens | 5 commodities | Coal, nickel, copper, iron ore, zinc-lead — off-grid exposure and its absence |
| Safeguard facility register | 208 facilities on 209 rows | Baselines, decline paths and 2029 compliance exposure, including the statutory floor |
| Storage project index | 601 projects | Announced and committed NEM storage, by owner, duration and stated date |
| Critical-minerals sites | 538 sites | Distance to the nearest substation, published power demand and the kind of gap where there is none |
| Mining tenement holders | 1,961 tenements | Who the state register records as holding the ground near a project, and what else that holder holds |
| Listed-company filings | 179 quarters | Cash position and the company’s own stated runway, read from its quarterly cash-flow reports |
| Dated company announcements | 6,695 announcements | When a project moved, to the day, from each issuer’s own published record |
Verification
We add the facility results and compare the total with independently compiled official data. The following checks compare our bottom-up results with official totals.
Facility-by-facility production summed and compared to published national totals. The aluminium result was within a fraction of one per cent of the national total. The alumina result was within a few per cent, and we identified the remaining difference.
National electricity generation reconciled against the register of designated generating facilities, and we then explain the remaining difference by fuel and state.
Facility carbon accounts cross-checked against independent pollutant inventories — using a pollutant inventory compiled independently from the Safeguard register.
Bottom-up site analysis reconciled against national energy statistics to establish a ceiling, not just a list. Published example: the diesel replacement market.

The Remote Mining Asset hybrid-energy screen shows the method end to end: the F1–F4 readiness assessment, the claim and evidence register and the owner-data requests it could not close. Other examples contain confidential or engagement-specific material and are not published.
