Largest wind farms in Australia: AEMO July 2026
Seaspray Off Shore Wind Farm in Victoria is the largest wind entry by reported nameplate capacity (MW AC), at 3,000 MW, and it is publicly announced. Golden Plains Wind Farm East in Victoria is the largest wind farm in service, at 756.4 MW.

Australia’s largest wind farm by reported nameplate capacity (MW AC) is Seaspray Off Shore Wind Farm in Victoria, at 3,000 MW in AEMO’s Generation Information release of 31 July 2026, and AEMO classes it as publicly announced.1 The largest wind farm in service is Golden Plains Wind Farm East, also in Victoria, at 756.4 MW.1 Of the 133,691.3 MW reported across the release’s 269 wind sites, 12,641.9 MW is in service.1 The same release sits behind our ranking of battery storage sites.
TL;DR
- Offshore projects are reported, not built. Seventeen of the 40 largest entries carry “offshore” in the site or owner name, and all 17 are publicly announced.1
- No wind site in service reaches 1,000 MW. The 40 largest reported entries run down to 1,000 MW; 39 are publicly announced and one, Bungaban Wind Farm in Queensland, is anticipated.1
- Victoria leads on both counts: 43,950.8 MW reported and 5,480.9 MW in service. South Australia reports the least, 6,071.9 MW, yet has 2,754.9 MW in service, close to New South Wales at 2,826.1 MW.1
- Headlines calling Golden Plains Australia’s largest wind farm describe a 1.3 GW project.2 AEMO lists its East row at 756.4 MW in service and its West row at 557.0 MW in commissioning.1
- In-service wind capacity was 12,641.9 MW in both the April and July 2026 releases, while anticipated capacity rose 1,783.3 MW and publicly announced capacity fell 4,795.6 MW.1
How this ranking was built
Glamdring Research ranked every wind site in AEMO’s NEM Generation Information release of 31 July 2026 on one field: reported nameplate capacity, Aggregated Nameplate Capacity (MW AC), from the Generator Information sheet of the release file.1 Rows with Technology Type set to Wind are in, and rows with the status Withdrawn are out.1 Generating-unit rows that share a site name and region were summed into one site, which leaves 269 wind sites.1
The extract records the count after that merge.1 It doesn’t record the raw wind row count or the number of withdrawn rows removed, so those two steps carry no figure here.
The second ranking keeps in-service capacity only. It counts AEMO’s In Service class and its Announced Withdrawal class, an operating plant with a closure announced; every other class is not yet built.1 The release’s wind status table carries no Announced Withdrawal line, so in-service capacity here is the In Service class.1 Figures appear as the release gives them. How Glamdring handles registry data is set out in our methodology.
Which wind farms are largest by reported capacity?
Seaspray Off Shore Wind Farm leads AEMO’s July 2026 wind list at 3,000 MW, followed by Deal 1 (West) Off Shore Wind Farm at 2,970 MW and Deal 2 (East) Off Shore Wind Farm at 2,968 MW.1 All three are in Victoria and registered to BayWa r.e. Australia Offshore Wind Projects companies, and every one of the 25 largest entries is publicly announced.1

Every row comes from the same release and the same field.1
The largest entry with no offshore marker is Collinsville Green Energy Hub in Queensland, fourth at 2,839.2 MW.1 Beyond the table, the list reaches 1,000 MW at 40th with Boort Wind Farm in Victoria.1 Only one of the 40 carries a class other than publicly announced: Bungaban Wind Farm in Queensland, 33rd at 1,155 MW, classed as anticipated.1
Read this ranking as a list of registered proposals by size. It shows where developers have put the most wind capacity on AEMO’s books, and the status column shows how little of the top of that list has reached construction or operation.
Which is the largest wind farm in service?
Golden Plains Wind Farm East in Victoria is the largest wind farm in service in AEMO’s July 2026 release, at 756.4 MW.1 Stockyard Hill Wind Farm, also in Victoria, is second at 527.6 MW, and Coopers Gap Wind Farm in Queensland is third at 452.9 MW.1
| # | Wind farm | State | In-service MW (AC) |
|---|---|---|---|
| 1 | Golden Plains Wind Farm East | Victoria | 756.4 |
| 2 | Stockyard Hill Wind Farm | Victoria | 527.6 |
| 3 | Coopers Gap Wind Farm | Queensland | 452.9 |
| 4 | Macarthur Wind Farm | Victoria | 420 |

| 24 | Dulacca Wind Farm | Queensland | 172.9 |
| 25 | Musselroe Wind Farm | Tasmania | 168 |
Victoria holds 12 of the 25, New South Wales 5, South Australia 4, Queensland 3 and Tasmania 1.1 The in-service leader’s 756.4 MW is about a quarter of Seaspray’s reported 3,000 MW, and it sits outside the 40 largest reported entries, which stop at 1,000 MW.1
For anyone asking what the grid can draw on today, this is the table that answers it. The first table answers a different question: what has been proposed.
How much of the reported capacity is offshore?
At least 26 per cent of the wind capacity reported in AEMO’s July 2026 release sits in entries marked offshore.1 Among the 40 largest entries, 17 carry “offshore” or “off shore” in the site or owner name, and together they report 34,772.7 MW of the release’s 133,691.3 MW.1 All 17 are publicly announced, and none of the 25 largest in-service sites carries the marker: offshore projects are reported, not built.1
Ten of the 17 are in Victoria, including the three BayWa r.e. entries and Orsted Gippsland 01 Windfarm, whose owner is Orsted Offshore Australia 1 Pty Ltd.1 Seven are in New South Wales, four of them OceanEx Energy entries at 2,000 MW each: Eden, Illawarra, Novocastrian and Ulladulla.1
The release extract has no offshore field, so this split is a name test applied by Glamdring Research. Two Victorian entries in the top 40, Star of the South Wind Farm at 2,205 MW and High Sea Wind Farm at 1,281 MW, carry no marker in either name or owner, and the test counts them as unmarked.1 Entries below 1,000 MW weren’t tested, which is why the share is a floor. Confirm any offshore classification against the developer’s own filings before sizing the offshore pipeline from this release.
Which states hold the most wind capacity?
Victoria holds the most reported wind capacity in AEMO’s July 2026 release, 43,950.8 MW across 79 sites, and the most in service, 5,480.9 MW.1
| State | Sites | Reported MW (AC), all statuses | In-service MW (AC) | In service as share of reported |
|---|---|---|---|---|
| Victoria | 79 | 43,950.8 | 5,480.9 | 12.5% |
| New South Wales | 83 | 42,734.5 | 2,826.1 | 6.6% |
| Queensland | 53 | 34,408.8 | 1,018.5 | 3.0% |
| Tasmania | 20 | 6,525.3 | 561.6 | 8.6% |
| South Australia | 34 | 6,071.9 | 2,754.9 | 45.4% |
| NEM total | 269 | 133,691.3 | 12,641.9 | 9.5% |
Site counts and megawatt figures are the release’s; the share column is Glamdring’s arithmetic on them.1
New South Wales has the most sites, 83, but trails Victoria on both capacity measures.1 Queensland shows the widest gap, 34,408.8 MW reported against 1,018.5 MW in service.1 South Australia runs the other way: it reports the least capacity of the five states and has 45.4 per cent of it in service.1
Each state figure is rounded to one decimal place, so the in-service column adds to 12,642.0 MW against the 12,641.9 MW total.1
What does AEMO’s nameplate figure measure?
AEMO’s nameplate figure is a registered capacity rating in megawatts. AEMO records 3,000 MW for Seaspray Off Shore Wind Farm.1 The field is Aggregated Nameplate Capacity (MW AC), and this ranking sums it across each site’s generating-unit rows.1
A capacity rating says nothing about how much energy a site delivers in a year. The Victorian Government’s figure for Golden Plains, more than 4,000 GWh a year once complete, is an energy estimate in a different unit, stated by the government.2
Status tells you how far each entry has gone. Of the 133,691.3 MW reported, 112,396.5 MW is publicly announced and 12,641.9 MW is in service.1 The rest is split across four classes: 2,182.4 MW in commissioning, 1,424.6 MW committed, 204.6 MW committed with an asterisk, and 4,841.4 MW anticipated.1 About 84 per cent of reported wind capacity is publicly announced and about 9.5 per cent is in service.1
Why do published figures for the same wind farm disagree?
Published wind farm figures disagree with AEMO’s release mostly because of scope and date: a project total set against a registered stage, or a construction-era report set against a later release. Golden Plains shows both.
Renew Economy reported in August 2023 that the first 756 MW stage of the up to 1.3 GW Golden Plains wind farm was under construction near Rokewood in Victoria’s south west.3 In October 2024 the Victorian Government said the wind farm had begun feeding into Victoria’s grid and that, once complete, it would be a 1.3 GW wind farm.2 The July 2026 release lists Golden Plains Wind Farm East at 756.4 MW in service.1 The release also lists Golden Plains Wind Farm West at 557.0 MW, in commissioning.1 East and West together make 1,313.4 MW, the 1.3 GW of the headlines.
Rye Park shows the figures agreeing. ESD News reported in May 2025 that the 396 MW Rye Park Wind Farm, north of Yass, had opened as the largest operating wind farm in New South Wales.4 The release lists Rye Park Wind Farm at 396 MW in service, the largest in-service entry in New South Wales.1
Stages registered under different names stay apart, because the merge joins rows only when site name and region match.1 Murra Warra Wind Farm stage 1 at 225.7 MW and stage 2 at 209 MW are two rows; together they make 434.7 MW, which would sit above Macarthur Wind Farm’s 420 MW.1 Goyder South Wind Farm 1A at 209 MW and 1B at 203.5 MW make 412.5 MW, which would sit above Rye Park.1 A publication that counts stages as one farm will print a different order from this one.
What changed since the April 2026 release?
In-service wind capacity didn’t change between AEMO’s April and July 2026 releases: 12,641.9 MW in both.1 The movement sits in the pipeline classes.
| Status | April 2026 MW (AC) | July 2026 MW (AC) | Change MW |
|---|---|---|---|
| In Service | 12,641.9 | 12,641.9 | 0 |
| In Commissioning | 1,625.4 | 2,182.4 | +557.0 |
| Committed | 1,733.6 | 1,424.6 | -309.0 |
| Committed* | no line | 204.6 | +204.6 |
| Anticipated | 3,058.1 | 4,841.4 | +1,783.3 |
| Publicly Announced | 117,192.1 | 112,396.5 | -4,795.6 |
The megawatt figures are the release’s; the change column is Glamdring’s arithmetic.1
Anticipated capacity rose 1,783.3 MW and capacity in commissioning rose 557.0 MW.1 Publicly announced capacity fell 4,795.6 MW.1 Summed by status, total reported wind capacity fell from 136,251.1 MW to 133,691.4 MW, a drop of 2,559.7 MW.1 One move shows in the site rows: Golden Plains Wind Farm West was committed at 557.07 MW in April and is in commissioning at 557.0 MW in July.1 The status totals don’t show the other moves, so it can’t say how much of the announced fall came from projects advancing a class and how much from withdrawals.
What the ranking cannot tell you
The release covers the National Electricity Market. Its state table lists Victoria, New South Wales, Queensland, Tasmania and South Australia only, so Western Australia and the Northern Territory don’t appear.1
The extract carries no commissioning date, expected completion date or annual generation for any site.1 A publicly announced row says a project is registered at that size. It doesn’t say the project will be built, or when.
Three labels go unexplained in the extract: the asterisk on Committed*, the “KCI” suffix on entries such as Great Eastern Offshore Wind - KCI, and raw owner entries such as “feraaustralia_nr” for Boort Wind Farm.1 The offshore split is a name test, not an AEMO field.
Every figure is dated to the 31 July 2026 release, and the ranking changes when AEMO publishes the next one. The revision will carry a change note and its sources: subscribe to the email briefing.
Frequently asked questions
What is the largest wind farm in the southern hemisphere?
The Victorian Government described Golden Plains Wind Farm as the largest wind farm in the Southern Hemisphere when it began feeding into Victoria’s grid in October 2024.2 AEMO’s release covers only the National Electricity Market, so it can’t test a hemisphere-wide claim. Within the release, Golden Plains Wind Farm East is the largest wind farm in service, at 756.4 MW.1
What is the biggest wind farm in South Australia?
Snowtown S2 Wind Farm is South Australia’s largest in-service entry, at 270 MW.1 AEMO registers Goyder South as two in-service rows, 1A at 209 MW and 1B at 203.5 MW, which together make 412.5 MW if counted as one farm.1 By reported capacity, the largest South Australian entry is Nonowie Wind Farm at 1,015 MW, owned by Tilt Renewables Australia Pty Ltd and classed as publicly announced.1
Are any offshore wind farms operating in Australia?
None appears in service in this release’s extracts. All 17 offshore-marked entries among the 40 largest are publicly announced, and none of the 25 largest in-service sites carries an offshore marker.1 The release has no offshore field, so entries below 1,000 MW were not name-tested.
