Last week the AEMO released a draft of the Marginal Loss Factors (MLFs) that would apply to both generation and loads connected to the NEM. This page on the AEMO…
Guest author, Allan O’Neil, drills into considerable depth to understand, and clearly explain, some of what happened during a volatile period in the VIC and SA regions on Friday 1st March 2019
Guest author, Drew Donnelly, compares case studies of Argentine and Australia to highlight risks in under and over-investment in network infrastructure
A quick article highlighting how the trend in aggregate number of unit starts, across the whole of the NEM, highlights the scale of one of the core underlying changes (and challenges) facing us in the NEM’s energy transition.
A collection of thoughts that have been bumping around in my head for some time about the latest push by various parties to facilitate a broader range of demand response in the NEM, and whether there are better options
A note of caution, that Demand Response is not a magic wand – it *can* achieve a lot, but if can’t be assumed to automatically appear to bridge any gap between supply and demand in a market model, for instance.
One more example of not focusing on the real problems seems to be a tendency for some to obsess about one narrow type of Demand Response (i.e. dispatch of NegaWatts) whilst seeming to lose focus of what the overall objective is (a more active and responsive demand side).
Yesterday I noted what appeared to be trips of two solar farms – Gannawarra and Karadoc – within a single dispatch interval and coincident with a period of volatile prices. Also yesterday, Dylan McConnell flagged a drop in output at the brown coal plant around the same time, with some questions. With the benefit of access to yesterday’s bids, today I have a look at the 5 power stations (pending a broader review next week by guest author, Allan O’Neil).
Some quick notes about the volatility seen in the NEM on Friday 1st March 2019 – a hot day in Victoria and South Australia, the first day of Autumn.
Now that summer 2018-19 has passed, we can reflect on our experiences as a new entrant energy services company facilitating spot exposure for residential energy users – and hence expanding the scope for Demand Response in the NEM.
