Winter 2007 – NEM-wide shortage of capacity

Posted by Paul McArdle Thursday, June 21 2007 Topic: Uncategorized

For two remarkable winter evenings in 2007 (19th and 20th June specifically) NEM-Wide Instantaneous Reserve Plant Margin (IRPM) plunged to the lowest levels ever seen in the NEM (a mere 7.6%) as generators were caught short of capacity by a cold snap that hit earlier than expected, whilst plant was still out for maintenance and other plant still suffering from drought-inflicted limitations of capability.

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.
