News Article Highlighting Opportunity for Demand Response
It was with interest that we stumbled on this article in the Herald newspaper talking about what happened on the 31st October in NSW
31st October 2008 – High Prices and Low Reserves in NSW
A tight supply/demand balance in NSW on the 31st October, exacerbated by transmission constraints into the region led to sustained higher prices in NSW.

VOLL Pricing on 23rd July 2008
It appears that we spoke too soon when we mentioned on the 22nd July that winter 2008 had been relatively uneventful.
Just over 24 hours from making these comments, we saw prices jump sky-high in the mainland regions, and go the other way (to the negative price cap) in Tasmania.
Long-Term Market trends and forecasts
As we have the time, we’ll provide some commentary here about the methods used by the various bodies for “long term” (which in the NEM means 10-years, typically) forecasting. Where they don’t fit elsewhere, we’ll also put articles here looking…
About Emissions Reduction
A topic containing miscellaneous articles covering aspects of emissions reduction technologies (including renewables) and schemes (including the CPRS, Emissions Trading and the Carbon Tax).
Winter 2008

Our Managing Director spoke at the “Australian Energy & Utility Summit 08” in

supplies, which might be unreliable.
NSW winter peak demand forecasts

“Power Prices Jump in Eye of the Storm”, from the AFR
Following from an alert to the situation provided by NEM-Watch, Duncan Hughes published an article “Power Price Jump in Eye of the Storm” that mentioned the extremely low levels of NEM-Wide Instantaneous Reserve Plant Margin (IRPM) that had occurred for a 60-minute period over both days.
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.
