Let's talk about Australian Prime Minister Scott Morrison's inability to face the truth about renewable energy

This was then Australian Treasurer Scott Morrison in late July 2017 on the subject of the Tesla battery planned to be used as part of the power grid in South Australia.

"By all means have the world's biggest battery, have the world's biggest banana, have the world's biggest prawn like we have on the roadside around the country...30,000 SA households could not get through watching one episode of Australia's Ninja Warrior with this big battery. So let's not pretend it is a solution."

Now when Morrison was mocking the South Australia government of the day he knew full well that the Tesla battery was never intended to supply energy in the same manner as a coal-fired power station – it was always intended to boost supply to keep energy flow from dropping below 49.2Hz and therefore minimise load shedding/brownout events. Media had discussed the issue in some detail.

Tesla boss Elon Musk built the battery facility within 100 days and the 100-megawatt lithium ion battery was switched on late last year to provide reserve capacity from renewable energy for the state’s electricity network.

According to the Australian Energy Market Operator (AEMO) executive general manager of operations Damien Sanford; "Its ability to respond very, very quickly to the different types of conditions that we see on the power system has been very encouraging for us". 

He told ABC News in October 2018 that; AEMO's data shows that it can dispatch power far more rapidly and precisely than conventional thermal power stations and more swiftly and accurately than the market operator thought possible — while also pushing down prices.

"We've been pleasantly surprised and would encourage more of this technology into the grid," Mr Sanford said.

ABC News also reported that; In the first quarter of this year, the cost of FCAS [Frequency Control Ancillary Services] fell by nearly $33 million, or 57 per cent, according to AEMO — in large part because of the introduction of the Tesla big battery.

The Tesla battery proved it worth in September 2018 when South Australia was isolated from the main grid by a lightening strike explosion in another state but despite this situation Morrison's 30,000 televisions were unaffected.
