24 April 2021 At the second day of the ‘Leaders Climate Summit’ convened by President Joe Biden, the former CEO of the Australian Energy Market Operator Audrey Zibelman, announced that the United States and the United Kingdom will be joining the Global Power Systems Transformation Consortium (GPSTC). “[Balancing supply and demand] has always been a difficult engineering challenge, but is becoming even more so as we decarbonise the grid,” she said. Zibelman cites her experience in the AEMO control room during the Black Summer 2020 bushfires. “We were losing major parts of the system. The limitations of our modelling and visualisation tools meant we had to act with incomplete information. Because it was all they had, our engineers relied on experience rather than accurate data to make critical decisions”, Zibelman said.
