Grid demand records smashed as W.A. becomes hottest place on planet

Western Australia Breaks Heat Records, Becoming Earth’s Hottest Region

Record Demand in Western Australia’s Main Grid Amid Extreme Heat

Western Australia’s main grid set a new operational demand record as parts of the state experienced scorching temperatures, making it one of the hottest places on Earth during the weekend. The Australian Energy Market Operator (AEMO) announced on X, previously known as Twitter, that the “operational demand” peaked at 4,233 MW at 5.55 pm (local time) on Sunday. This surpassed the previous record of 4,170 MW set on February 1.

During this peak demand period, the energy supply mix consisted of 58 per cent gas, 32 per cent coal, 4.7 per cent wind, 2.3 per cent battery storage, and 3.3 per cent from other sources. Notably, rooftop solar generation, which was not factored into the operational demand figure, likely contributed around 300 MW to the overall demand at that time, having played a significant role in earlier generation throughout the day.

Challenges with Data Reporting

Despite the remarkable demand and supply dynamics, AEMO faced challenges with its market dashboard’s functionality following a market design update late last year. This hindered the accurate representation of how different energy sources performed over the weekend, leaving gaps in the data analysis.
