March was the least eventful month for Q1-24, with lower spot prices for most of the month apart from a Labor Day long weekend heatwave for VIC and SA, and some oppressive humidity hitting QLD later in the month. Both occasions coincided with low levels of VRE resulting in high price volatility.

In February VIC and SA solar farms had a big uptick in weighted average prices. Wind weighted average prices were also higher for all regions except QLD. VIC maximum generator outages were exceptionally high due to the Loy Yang A outage caused by a forced trip on 13 Feb.

Summer finally arrived for the southern NEM states, forcing Victorian transmission lines to topple on 13 Feb and when combined with the extreme heat, resulted in significant price volatility. The FCAS market in SA also experienced volatility on 13 Feb, racking up more than $6m in costs.

Forward prices rallied in QLD and NSW during February as a result of strong demand and high spot prices. VIC prices were affected by the massive power outage on 13 Feb with the Q1-24 price jumping $20/MWh. In contrast, SA forward prices continued to free fall with all tenors approaching $80/MWh.

For the first time in years, VIC wind farms generated at a premium to the spot price while SA wind farms were very close to generating at a premium due to very low spot prices. The news of the early closure of Snuggery and Port Lincoln Power Stations was also a notable development in January.

Hot and muggy weather in the north and mild weather in the south made for two very different stories in the electricity spot market during January. In the north, QLD recorded its second highest January average spot price while down south, Victoria had record low levels around $22/MWh.

Record demand and extreme prices in January drove up the QLD forward market and to a lesser degree NSW, while down south in VIC and SA, a weak summer has driven forward prices towards the floor. The market has since decided these high prices cannot be sustained and forward prices have nosedived.
