Today (Tue 23rd May) is the go-live date for AEMO's EMMS v5.2 - which will contain new data for some market enhancements. Here's a quick look at where this first change will appear in ez2view, highlighting some considerations for Semi-Scheduled units and self-forecasting.
We delve deeper into dispatch availability self-forecasts and the assessment process to further enhance our understanding of this important aspect, testing sensitivity to gate closure times and requirements on minimum intervals.
In today's article (a third snippet from GenInsights Quarterly Update for Q4 2022) we take a look at levels of large 'Aggregate Raw Off-Target' (i.e. large collective deviations away from Target), which continue to grow for the Semi-Scheduled category and remind us of that question...
Here on this site, and also in real discussions in the offline world, we have been pondering this question for a number of years. For instance, it was pondered in Theme 13 (‘What’s the future for Participation Categories in the NEM?’) within the 180-page analytical...
