NSW had the strongest average spot price for the NEM in May. Across the NEM prices were correlated with wind generation, with periods of high wind, crushing spot prices, and low wind combined with cold weather pushing up prices. Gas spot prices softened in line with the ACCC netback price.

So far Q2-25 spot electricity prices are following the footsteps of Q1-25, by not living up to expectations set prior to the commencement of the quarter. May-25 trades volumes were high as is normally the case, but less than May-24 levels. LGC prices strengthened and VEEC fell markedly.

The NEM expanded by 201MW in April. Wind farm GWA prices aligned better with rising spot prices, while solar farms showed contrary trends. All regions suffered higher wind curtailment than last April. TAS hydro generation hit a seven-year April low, deepening dependence on VIC’s exports.

Mild April weather led to subdued demand and average spot price outcomes across the NEM, except for short evening peak volatility for QLD and NSW early in the month. In the news, success for Labor Party confirms the ongoing transition to renewables and a strong stance on emission reduction targets.

The Q1-25 quarter spot prices finished in the bottom quartile of our spot forecast, creating a significant seller’s margin profit for the quarter. Forward market prices generally rallied during the month, reversing the February downward trend.

In March, 1,147MW of new capacity was connected. QLD was the only region to enjoy an increase in Generator Weighted Average prices, while wind weighted prices fell for all regions. SA solar and wind suffered the most curtailment. VIC was the dominant energy exporter and NSW the largest importer.

The Q1-25 quarter electricity spot prices finished at an unremarkable level, except for Tasmania. Variable Renewable Energy performed strongly, and gas generation was low. Meanwhile, gas spot prices also remained calm, while storage levels were filled, with a falling forward market.

Tasmania’s average spot price for February was the highest in the NEM, despite exceptionally low demand and accounted for almost half of all FCAS cost for the month. East coast gas spot prices remained high at around $13.50/GJ for the DWGM, and $12.50/GJ in Victoria’s STTM.

February brought no new connections to the NEM. Generator-Weighted Average prices improved for solar and wind across most regions, except QLD. Solar and wind farms continued to face large curtailment. VIC was the dominant energy exporter while TAS was the biggest importer in February.

The Q1-25 spot price continues to struggle to meet pre-summer expectations and the forward market has now resigned to this lower level. The lower Q1 prices have led to the FY-25/26 forward prices also softening in the northern States.
