Storms on February 4, 2025, and links to wind farm outages
Inspecting unit data at Willogoleche Wind Farm to ascertain drivers of the outage on 4th of February, 2025.
ELAV (elements available)
From mid-August 2024 the AEMO increased the transparency of actual (i.e. physical, as distinct from energy-constrained) availability of Semi-Scheduled generators by commencing the publication of two separate, but related, SCADA level data sets they receive from the Wind and Large Solar generators:
(a) LOCL (local limit)
(b) ELAV (elements available)
This was noted in the article ‘AEMO commences publishing actual intermittent generators (SCADA) availability data to the EMMS Data Model’.
Here we collate articles tagged with ‘ELAV (elements available)’.
Further on the N_NEWENSF1+2_100-INV constraint around the 14:00 dispatch interval on Wednesday 15th January 2025 … Part 8
We understand how the solar farm units received targets of 0 MW, when the constraint appears to simply limit the inverter count to 100.
A couple of wind turbines returned to service at Murra Warra 1 Wind Farm in Victoria
Finding another use for the relatively recent addition of the ELAV data set for Semi-Scheduled units, we follow on from a RenewEconomy article (in Nov 2024) to trend the availability of the Murra Warra 1 Wind Farm.
Further analysis (and more questions) about four VIC Wind Farms on Monday 16th December 2024
In this article, we’re continuing to explore what happened to some Wind Farms in Victoria on Monday 16th December 2024 – which was a day of high temperatures, and on which many interesting things occurred. In this particular article, we focus on 4 x Wind Farms all in the same portfolio that exhibited some commonalities in output patterns and so on…
AEMO commences publishing actual intermittent generators (SCADA) availability data to the EMMS Data Model
The AEMO began publishing actual intermittent generators (SCADA) availability data:
(a) to the EMMS Data Model in the Production environment from August 13th 2024 and
(b) to NEMWeb from August 14th 2024.
