Monday 16th December 2024 was an interesting day in the NEM for a number of reasons. So we’ll use the ‘Bids & Offers’ widget in ez2view to do this quick initial review and then, depending what we see, determine whether we want to invest further time to delve deeper…
A short after-the-fact note to confirm NEM-wide ‘Market Demand’ was (as predicted) highest since 31st January 2020 (almost 4 years ago) … in a case where AEMO Operational Forecasting team nailed the demand in forecasts more than 3 days earlier. Take a bow!
