It was a brisk walk to work this morning (Tuesday 10th June 2025) and, even with the sun still up, a cool walk home late this afternoon. A little later on we see this snapshot from NEMwatch at the 18;10 dispatch interval (NEM time):
Amongst the things we can note include:
1) Prices elevated across all regions … but not super-normal
2) Driven by the tight supply-demand balance:
(a) With NEM-wide ‘Market Demand’ at 31,402MW in this dispatch interval … and all regions with demand elevated out of the ‘green zone’.
(b) With spare capacity under 6,000MW (i.e. surplus to demand) this means a NEM-wide IRPM of 19% (down below 20% signifying the start of tightness)
(c) And, in this snapshot, not a single interconnector constrained … which is quite rare.
I have successfully installed a 2kVa ‘run of the river’ micro hydro system for an individual off grid (at that time) resident downstream of the Tinaroo dam in NQ. Unfortunately the 1980’s flood washed everything (including the house) away. The principle is very sound and could be repeated. Where can I find an organisation to discuss this idea.
