26th January 2006 - high demand and price in Victoria and SA

There was a high level in demand in Victoria on Thursday 26th January 2006.

This was especially remarkable, considering that it was an Australia Day public holiday – when commercial (though not industrial or residential) demand could be expected to be somewhat lower than would otherwise be the case.

Coupled with this level of demand was a significant spike in price that lasted several hours.

23rd January 2006 - new record for peak NEM-Wide demand

Based on forecasts NEMMCO had been providing through their PASA process, we expected that it might prove that this week would deliver huge demand levels, and high prices.

Not to disappoint, the market did deliver high levels of demand in all regions:
(a) Peak demand levels were reduced somewhat from the huge levels the previous week in Victoria and South Australia;
(b) Demand levels were also still building to the record level to be experienced the following week in NSW;
(c) Peak demand levels in Queensland were fairly steady (and high) for most weeks of summer.
(d) In combination, a new NEM-wide peak demand target of 30,994MW was set on Monday 23rd January.

7th February 2006 - price spike in Tasmania

This week saw very low average prices across the NEM (below $21/MWh average across the week in all mainland regions).

Except for 2 half-hours in Tasmania on Tuesday 7th February (when the price rose to just over $1,000/MWh), prices in Tasmania remained at and around $30/MWh for the whole week.

24th February 2006 - price spikes in Victoria

Demand in Victoria peaked again, bringing with it high prices in Victoria and (to a lesser extent) South Australia.

Indeed, the demand experienced in Victoria (on Friday 24th February) exceeded the previous high level of 8,552MW for summer, set in January 2006.

Our analysis looked at generator behaviour on the occasions of these price spikes.

Weekly summary of events in Summer 2005-2006

Summer 2005-06 saw Australians sweltering in temperatures 40 degrees and above.

In the National Electricity Market, this led to new peaks in demand and (given the tight supply/demand balance) delivered high (and volatile) spot market pricing.

Here we have compiled a weekly summary of events in the NEM over summer 2005-06.
