First time I have noticed negative price from Qld – minus $1,000 MW 3.20am 13 July 2017 – tick “QLD” on left and “5 Min” on right. Who knows why? Just more Govt madness. Not uncommon lately to get negative price periods in Tasmanian data. NEM Dispatch Overview always worth checking – see how Qld is the “anchorman” of our grid. NemWatch gives a generation snapshot.
