Not long after speaking with a client about forecast evening volatility in NSW for Wednesday 15th January 2025, we see price spikes beginning at 14:00 in the afternoon. So we take a first look….
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).
The NSW volatility events on 17 and 20 May and on 16 March were characterised by constrained VNI flows and high (2000 MW) Tumut hydro output. Is the VNI constraint causing the high hydro output or is the high hydro output causing the VNI constraint? Is there a lack of capacity in the Snowy 330 kV network?
