Market Report

There were 861MW of new generation connections in May. Despite rising wind and solar Generator-Weighted-Average prices, most NEM regions continued to have large discounts to their Time-Weighted-Average prices. Additionally, most NEM regions reported lower wind and solar curtailment rates.

May was marked by extreme price volatility in NSW where the CPT was exceeded on 8 May triggering Administered Pricing, while low wind generation contributed to high average spot prices in the southern states despite lower demand levels. Gas spot prices soared averaging above $13/GJ for all regions.

The month of May once again reflected a change in perceptions of the future electricity prices, and continued the history of being the most heavily traded month along with November, each calendar year.

The NEM continues to wait for the first new generation connection for 2024, marking the longest stretch with no new connections since 2018. Wind and solar generators performance fell in April with larger discounts to the spot price. In brighter news, wind and solar curtailment continues to fall.

Spot prices strengthened in April with a very high portion of price outcomes between $100 to $300/MWh pushing the NEM average April price to $85/MWh compared to $75/MWh for Q1-24. Forward prices significantly rallied during the month. Gas spot prices also strengthened but averaged just below $12/GJ.

Based on our probabilistic spot forecast for Q2-24, we recognised that the forward market was likely to be under-valued. As events have played-out, this proved to be true and the market rallied, not only for Q2-24, but through the whole forward curve.

Q1-24 marked the first time in six years that the NEM had no new generation connections. March also saw lower generation and GWA prices for wind and solar farms across most NEM regions, except for SA. Curtailment of VRE was in seasonal decline but remained high for March in SA and VIC.

The electricity forward market rallied in the southern states as news of potential gas shortages for Victoria circled in the media. Q1-25 traded most heavily during the quarter, especially for QLD which remains stubbornly high despite the return of Callide C3 and the expected return of C4 this July.

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.
