Summer 2010-11 in the NEM
Some articles, as we put them together, focused on events of summer 2010-11
A very modest start to summer peak demands

How the drought of 2007 affected specific power stations
I have been asked a couple of times recently, by new entrants to the NEM, about the impact of the drought in 2007 on generation levels around the NEM. This prompted me to look at what we had posted previously…

A listing of some drivers for higher (and, in some cases, lower) prices in the wholesale spot component of the NEM.
Fuel Costs – some views supporting higher electricity prices in the future
Some thoughts about drivers supporting higher fuel costs – and hence driving electricity prices higher in future (assembled from comments made at EUAA events, and elsewhere).
Trend in annual Generator Utilisation by Region

Fuel Supplies in the NEM
Some articles, as they are prepared, in relation to fuel supplies in Australia’s National Electricity Market (NEM). This could be to do with coal supplies, or gas supplies, or in relation to other fuel.
Some possible implications of the takeover bid for Centennial Coal
Preliminary thoughts about some of the possible implications of the agreed takeover of Centennial Coal by Thailand’s Banpu, and the long-term strategy to re-balance coal supplies evenly between domestic supplies to the National Electricity Market, and international supplies to generators across Asia.

Brief recap on the historical trend in spot prices in the NEM
Some analysis of the way in which prices in the Australian National Electricity Market have trended over time, from as far back as 1994 (in the markets that were precursors to the NEM).

Background to Winter 2010 in the NEM
Inspired by the price spike experienced this evening, I have spent a little time to put together the background to winters in the NEM.
This will be useful in understanding the context of any other events that occur this winter, and are analysed on WattClarity.
