Analysis of price volatility in the QLD region over summer 2007-08

Our Managing Director was asked to speak at the “Queensland Energy” conference in Brisbane on Wednesday 12th March – specifically addressing the topic of price volatility in the NEM.

To provide the basis of discussion during the conference, we focused our analysis solely on Queensland region (to make the topic more manageable).
In our review of volatility in the Queensland region, we focused specifically on 3 core attributes of the market: Queensland dispatch prices; NEM-Wide Instantaneous Reserve Plant Margin; and the concept of “Economic Islands”.

    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?
