Wednesday morning 12th February 2024 sees rapid and large oscillations in prices across all regions – which results from (and/or leads to) oscillations in output of many units. One of the contributing factors is suspected to be the newly composed ‘N-BU_330_TX_ONE’ constraint set for an outage related to Project Energy Connect.
With warnings that tomorrow could see high (higher!) demand in South Australia, we take a quick look at high demand experienced on Tuesday 11th February 2025.
DTN (a.k.a. Weatherzone) says tomorrow South Australia might see ‘hottest day in 5 years’. Well, correlated with that, AEMO forecasts show it might see highest ‘Market Demand’ in 11 years!

A fourth update in what’s visible in the market data about Industrial Action at Gladstone Power Station
Friday 31st January 2025 (appeared to) experienced a very large drop in demand in NSW in a single dispatch interval – but we’re now suspecting some form of data/operational glitch.
