A collation of articles pertaining to the obligations of Semi-Scheduled units operating in the NEM.
Our GSD2023 was released just over 4 weeks ago. This is the second sequential article utilising the GSD2023 Data Extract to take a look across all the Semi-Scheduled units (i.e. Wind and Solar). In this case looking at use of Self-Forecasting, and revealing more questions …
Read MoreOur GSD2023 was released just over 4 weeks ago. Finally today I have a chance to utilise the GSD2023 Data Extract to take a look across all the Semi-Scheduled units (i.e. Wind and Solar) and see who’s been using MaxAvail in their bid to limit their plant availability … and the DUIDs that have not yet used this new facility.
A week’s worth of data provides indications of how semi-scheduled generators are using bid MaxAvail to manage dispatch availability.
It is indispensable to understand how the semi-scheduled unit availability gets produced to optimally manage the critical inputs and comprehend dispatch outcomes. This article explains the key inputs and processes, focusing on the dispatch timeframe.
The change to use MaxAvail from the energy bid, for semi-scheduled units, was implemented on 7 August 2023.
2 x AEMO Market Notices this afternoon prompt this article about four upcoming Market Enhancements … with the first to planned to commence from next Monday 7th August 2023
AEMO is re-enabling the ‘MaxAvail’ figure in bids for Semi-Scheduled units. It will act as a limit on capacity available, feeding into the NEMDE dispatch process for the unit. We look at how Semi-Scheduled plant have currently been treating MaxAvail in the bid and share some insights.
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…
This first excerpt from GenInsights Quarterly Update for Q4 2022 looks specifically at the trended level of adoption of self-forecasting for Semi-Scheduled Solar Farms in the NEM. This article on Monday 26th February 2023 precedes some changes AEMO might make on Tuesday 27th February 2023.
Today, more than 14 months after the publication of GenInsights21 we’re sharing Key Observation 15 of 22, relating to self-forecasting for Semi-Scheduled units.
A short article, to record the upgrade of the ASEFS and AWEFS forecasts for Semi-Scheduled (i.e. Wind and Large Solar) units.
On Thursday 17th March, Jonathon Dyson presented at the CEC Wind Industry Forum in Melbourne about the increasing role of auto-bidding and self-forecasting in the modern-day NEM. In this article, he shares some of the key points from that presentation.
This morning the AEMC has published its final rule focused on clarifying how Semi-Scheduled generators should follow dispatch targets – including in dispatch intervals where prices are negative, and some had been unexpectedly switching off.
As promised in the Intermittent Generation Forum late in 2020, the AEMO has released an important Handbook for operators of Semi-Scheduled (wind and solar) assets.
Following up to AEMO’s recent Intermittent Generator forum, Marcelle looks at the challenges for wind and solar farms in providing consistently good plant availability information to AEMO and the value of transparency of this data.
Following the consultation process conducted by the AER (stemming from their Issues Paper 3 months ago) the AER has today submitted a rule change request to the AEMC relating to Semi-Scheduled generation.
Following on from Friday’s article (which considered the AER Issues Paper) this article delves into more detail of those extremes of ‘Aggregate Raw Off-Target’ across all Semi-Scheduled units that have been recorded over the past 10 years. There’s a clear clustering of cases in 2019 – what does it mean?
