Solar peak 5,493 MW at 12:50, 18 Oct · Batteries most charging 3,194 MW at 13:10, 18 Oct · Most discharging 3,926 MW at 18:45, 18 Oct.
Scheduled and semi-scheduled units on the NEM (Qld, NSW, ACT, Vic, SA, Tas): large solar farms and grid batteries, not rooftop solar. WA and the NT aren't on the NEM.
How the totals are added
Solar totals add positive readings only. A small negative reading is the farm's auxiliary load at night.
Battery figures are net: negative is charging. A gap is an interval with no file.
By region
| Region | Large solar | Batteries, net |
|---|---|---|
| Queensland | 916 MW | charging 212 MW |
| New South Wales and the ACT | 2,969 MW | charging 1,206 MW |
| Victoria | 570 MW | charging 768 MW |
| South Australia | 110 MW | charging 308 MW |

Unit health
Solar and battery units sending readings.
- Reporting
- 185 of 185
- A reading in the last 3 files
- No reading for 15 minutes
- 0
- Near zero at midday
- 0
- Solar, 20 MW and up, under 2% of registered capacity, 12:00 to 13:00 AEST, 18 Oct
Near zero at midday can mean dispatched down (negative prices or a network constraint), an outage or maintenance. This data can't tell which.
Where the readings come from
Generators and batteries on the NEM send AEMO their output in MW over SCADA. At the start of each 5-minute dispatch interval, AEMO writes a snapshot of every unit to one public file. It is listed on NEMWeb a minute or two later, and we check every minute.
This reading reached us 5 min 16 s after it was taken.
36 of the 517 readings in the latest file are from units not on the registration list, 40 from non-scheduled units. They're left out of every total.
