Cost of congestion to energy users

For the EUAA’s Members Meeting (held in Brisbane on 24th April 2008), our Managing Director was invited to provide of a précis of the presentation he previously provided at the “QLD Energy” conference (on 12th March 2008).

In particular, comments made by Paul with respect to the proposed upgrade to QNI – which was topical at the time of the conference, given that Powerlink and TransGrid had released their analysis of several upgrade options in the same week as the conference.

As a result of the presentation, Duncan Hughes wrote an article about the potential cost to energy users of the upgrade, and published this in the Australian Financial Review on 13th March 2008.

Given the magnitude of the numbers reported, this issue has proved to be of significant issue to large energy users – hence the invitation to present at the Member’s Meeting.

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”.

22nd and 23rd February 2008 – a rare hot spell in Queensland

In Queensland we experienced one of the mildest summers I can remember. As a result of this, demand levels were subdued for most of summer. However, for a couple of days in late February, summer finally arrived, and struck with a vengeance.
