The damage inflicted by a good wind day. The first version of this post focused on choke points that are the fatal flaw of Renewable (unreliable) Energy. This is a reminder about the way RE kills the coal-fired providers and eventually the whole grid if the windrush continues. On Sunday March 16 the black coal supply fell to the lowest level that I have observed: this was 8.4GW and on Sunday between 11am and 3pm it fell to 8.1. That was the result of substantial wind and also rooftop solar until it began to fade near 3 (Sydney time). Then black coal ramped up sharply, followed by gas and hydro.
The shape of things to come, see also Perth. Smaller grids are more prone to disruption of course, so in Darwin the intrusion of RE threatens blackouts.
Households and businesses in the Northern Territory face an immediate and growing risk of costly electricity blackouts because governments and regulators have failed to adequately prepare for the growth of renewable energy, industry experts say.
The Territory Labor administration’s hand-picked solar tsar, Alan Langworthy, has joined the recently departed head of the region’s leading fossil fuel generator, Tim Duignan, to blow the whistle on a range of problems.
Mr Duignan was sacked late last year over a system-wide blackout in Alice Springs that an official report linked to a single cloud.
SA WATCH. At 7.30 this morning SA was exporting 105MW of power, by noon it was slightly in the red and at 1.30 they are taking in 60MW. They are generating 402MW towards their meagre demand of 877MW and the mills are running at 20% of capacity.
SA at 5.30. Importing 101MW. Next to no wind, 6% capacity in SA and contributing 120MW!! Australia wide 16% capacity, 1.1GW to meet 24.5GW demand. 4.4% Go wind!
SA at 7.30. Demand 1636, local supply 1236, wind 92, 6% of demand, 4% of capacity. Importing 400MW.
SE Australia NEM at 7.30 Demand 24.9GW, wind providing 1.3GW, (5%) at 19% of capacity.
