In this article we take the estimated gross injections from Small Solar (both AEMO and APVI estimates) across both days – and compare them, to gain some sense of what the quantum and timing of ‘missing’ Small Solar might have been on Monday 12th October...
On Tuesday 25 August SA Power Networks had planned to conduct its annual test of its ability to temporarily curtail rooftop solar generation.
A look at how AEMO’s short-term forecasts have performed at the daily peak in Queensland over the past seven summers — and how that performance is changing as rooftop PV grows.
In this guest-authored article, Connor James explains the upcoming changes to the DMO, including the much publicised Solar Sharer Offer (SSO), and potential implications for energy sellers in NSW, SEQ, and SA.
Information spanned a wide range of topics related to intermittent generator forecasting, and included a guest presentation by the AER.
We earlier noted this ‘Significant (-786MW) drop in NSW demand, on Wednesday 13th November 2024’ … and, in response, a reader (KC) asked a question that inspired this article.
Perhaps contributing to the early start to price volatility in NSW this afternoon was the wobble in system frequency shown here?
On Thursday 10th October 2024, we published ‘What happened with System Load in VIC on Friday 27th and Saturday 28th September 2024?’ and, in doing so, listed some times when rooftop PV was disconnected (or consideration was given to the same). In this article (following...
Third article already on Friday morning 27th Sept 2024, looking forwards to a forecast 'Minimum System Load' event in Victoria in parallel with the AFL Grand Final tomorrow (Sat 28th Sept 2024).
Two days in a row, the AEMO has issued its first and second alerts (via Market Notice) about forecast Minimum System Load events for Victoria. This second alert for Friday 27th September 2024.
The AEMO has issued its (second* ever) 'Minimum System Load' alert, via Market Notice 118421, with respect to Victoria for this Saturday 28th September 2024.
Sunday 18th August 2024 sees Queensland reach a new 'lowest' point for 'Market Demand' ... not quite 8 months after it saw a 'highest ever' point for 'Market Demand'. Stretched at both ends, and a clear indication of the challenges of this energy transition.
The wet weather in Queensland has impacted solar energy production.
The Russ Christ Effect can be described as cloud impacts on rooftop PV arriving before any associated cooling conditions. We consider the extent to which a sudden and unforecast jump in demand was driven by this phenomenon.
Some interesting data coming from our forecast convergence widget yesterday afternoon, hinted to us that bushfire smoke is likely to have been impacting rooftop PV generation levels in Victoria.
Tristan Edis of Green Energy Markets argues how system longevity, battery-coupling, distribution network capability, and increasing capacity will shore up rooftop PV's position in the market.
An an elevated risk of the contingent disconnection of Distributed PV resurfaces for SA on 15 February 2024 with market notice 114743.
Clutch's Mitch Baker has shared his initial thoughts and questions that jumped out to him from reading the AEMO's 2024 draft ISP.
A quick look back at Saturday 6th January 2024 in South Australia - and the case of an unforecast drop in 'Market Demand'
Guest author Allan O'Neil continues our series of posts on very low system demand levels in South Australia and Victoria on New Year's Eve, with a few unresolved questions remaining
