Record low QLD and NSW prices for 2026 and 2027 have evolved while VIC has held firm at lower levels. However, by mid-2028 the Yallourn closure will trigger the price bounce consolidated by the Gladstone and Earing closures in 2029. Higher prices are then expected to prevail for the next 3 years.

During the National Electricity Market’s life, a forecast of 40 °C in Melbourne heralds high or record demand, a reduction in turbine efficiency, reserve squeeze and high interconnector dependency causing NSW price separation with extreme Victorian spot prices. However, has the market changed?

The NEM expanded by 9,142MW in 2025. Solar generation captured a shrinking value as solar prices diverged from average spot prices, whilst LGC prices collapsed during the year. SA solar had nearly two-thirds of potential energy curtailed. Heywood and Basslink had more network constraints.

With the conclusion of 2025, this spot price report analyses the trends, drivers, and underlying factors shaping electricity spot prices across the NEM. The insights provide a snapshot of the latest trends and the evolving energy market landscape.

Record-shattering wind, Q1-26 swaps and caps trading tell a story, plus fresh coal-plant hiccups impact prices and risk. At times renewables are crashing prices, but volatility is flexing and premiums are being paid while potential volatility prevails.
