Australia’s Mining and Resources sectors are bracing for a wet season shaped by one of the most rapidly developing El Niño events on record. Looking back at how the strongest El Niño events in Australian history have played out, it becomes apparent that mining operations in Australia should be planning for a later monsoon […]
Australia just had its warmest winter on record across large parts of the country, and the mild weather produced the lowest gas output since 2004 and cut wholesale electricity prices nearly in half. Despite the unusually warm winter, demand hit a new NEM-wide winter record of 24,220 MW — but ample rooftop and grid solar meant the […]
WA’s remote mining regions have been impacted by thunderstorm, lightning and heavy rainfall only detectable using remote sensing methods. Nearly 300,000 lightning strikes detected across WA DTN Total Lightning Network (TLN) detected over 288,000 lightning strikes above Western Australia between Wednesday and Sunday, August 26-30, 2026. A vast majority of this lightning was observed over […]
A strong El Niño and an unusually stable Antarctic polar vortex are setting up a spring signal of light winds, elevated solar output, and a real risk of high-intensity heatwaves for the NEM. This forecast could be a major flip to what the National Electricity Market (NEM) has experienced so far during Winter 2026. On 1 July 2026, the NEM […]
