Die grosse Tesla-Batterie hat den Strom-Konsumenten im ersten Jahr rund 40 millionen Dollar an Kosten erspart dadurch, dass die Netzwerkstabilisierung nun nur noch einen Bruchteil kostet.
Ein Vorfall, am Tag nachdem sich ein führender Politiker über die Batterie lustig gemacht hat zeigt sehr gut, was nur eine Batterie kann:
First the battery responded to a major fall in frequency by injecting 70MW into the grid, and then as other states lost generation and had to shed load for households and big business in NSW, Victoria and Tasmania, and the connection to South Australia was lost, the battery switched to full charging capability in an instant – or 0.13 seconds to be precise – to keep the lights on in south Australia, where no load was shed.
“The human eye takes 0.3 seconds to blink. We can go to full output and back in less than the blink of an eye, “ Heron said. “It is remarkable. If that battery was not there, there could have been a real loss of power in South Australia.
“Once the interconnector tripped, it did a world first – going the other way into charging mode, to absorb some of the additional energy coming out of south Australia.
“It is the First time something like that has been done in the network. It’s always easy to drop load, quite different to switching it on all of a sudden.”
