Performance Of Tesla’s Australia Battery Has Been ‘Outstanding’

The Sydney Morning Herald:

When it comes to hype, there is probably nobody as outlandish as US-based billionaire Elon Musk and his Tesla corporation.

A…version of the hyperbole has been on show in Australia, following the installation late last year of a 100-megawatt lithium ion battery – the world’s largest. Musk famously offered to supply it for free if his firm couldn’t build it within 100 days.

The big battery, located next to the Hornsdale wind farm in the mid-north region of South Australia, has already been active, drawing interest from well beyond these shores.

While the hype rings a bit hollow…there’s no doubt the battery has been making a difference, responding to four coal generator trips in December alone.

Franck Woitiez, managing director at Neoen – the French operator of the battery – told Fairfax Media its performance had been “outstanding. We are very proud of the battery performance throughout December and the start of January.”

According to [Dylan McConnell, a researcher at Melbourne University’s Climate & Energy College], the battery dispatched about 2.5 gigawatt-hours of electricity while consuming about 3 gigawatt-hours, representing a round-trip efficiency of about 80 per cent. “The performance to date has been very impressive. It’s ramp-up from zero output to maximum in seconds (or less) is something that we haven’t seen in the electricity market before,” McConnell said, noting the current fleet of “fast start” units take five to 10 minutes to synchronise to the grid and start providing power.
