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)’.
It was now just over 5 years ago when Marcelle wrote ‘Not as simple as it appears – estimating curtailment of renewable generation’. This week's invocation of the 'N-DPWG_63_X5' constraint set provides a great...
Inspecting unit data at Willogoleche Wind Farm to ascertain drivers of the outage on 4th of February, 2025.
We understand how the solar farm units received targets of 0 MW, when the constraint appears to simply limit the inverter count to 100.
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...
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...
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.
