In this article we look more closely at 1st and 2nd February 2022 – and particularly at where and when the changes in rooftop PV occurred, narrowing our assessment to south-east Queensland regions. It follows on from Part A which inspected how Queensland rooftop PV output varied at the state level.
AEMO recently imposed additional dispatch obligations on six non-scheduled wind farms in South Australia. We take a look at what this means in practice.
From 10:00 today (Friday 10th September 2021), ElectraNet’s new synchronous condensers (which have been under testing) will be deliver a boost to Semi-Scheduled units in South Australia.
Looking back at Tuesday 13th April 2021 – a day in which the ex-tropical cyclone Seroja in Western Australia caused some wobbles in rooftop solar PV output in South Australia.
Following recent articles on spot market revenue earned by solar farms in the NEM in 2020, Marcelle takes a look at their FCAS costs.
Marcelle extends last week’s comparison of solar farm energy spot market revenue in 2020 by adding in an estimate of the LGC (green certificate) revenue.
Which solar farms performed best in 2020? Marcelle compares spot revenue performance across the NEM.
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.
This is the fourth of a short series of video snippets extracted from the 17th September 2020 presentation by Marcelle Gannon and Jonathon Dyson for the Clean Energy Council entitled ‘Maximising Profitability in the NEM’ for Wind Farms.

On 25th November, guest author Allan O’Neil examined the ‘X5 Constraint’. Two weeks of operation have passed, so now Allan reviews some of what’s happened.

Today (Thu 19th Nov 2020) the AEMC published a draft ruling following the AER request for a rule change relating to Semi-Scheduled generators … which itself followed from two COAG Energy Council requests to them
A brief note to inform readers that the AEMC is fast-tracking consideration of the AER’s Proposed Rule Change on Semi-Scheduled assets … but also to reinforce our view that the challenge is MUCH broader than is being addressed here.
This 20th Case Study (the other side of the weekend to the 19th Case Study) in the series investigates one dispatch interval showing extreme Aggregate Under-Performance across all Semi-Scheduled units on Monday 8th April 2019.
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.
This 19th Case Study in the series investigates one dispatch interval showing extreme Aggregate Under-Performance across all Semi-Scheduled units on Friday 5th April 2019.
