Oopsie solar-battery fail? Cloud causes System Black event at Alice Springs affecting thousands

Welcome to the new complexified energy grid where a cloud can cause a system black event — knocking out power for as much as nine hours. This affected the hospital for 30 minutes and the prolonged problems caused many businesses and supermarkets to close. Alice Springs is an island microgrid servicing about 29,000 people in the centre of Australia. It was 38 degrees C yesterday when the power went out. Shame about those fridges and air conditioning units.

Alice Springs is a mini version of larger grids showing how fragile these new complicated systems of multiple generators based on weather events and batteries can be.

Thousands of residents in Central Australia went without power yesterday afternoon, with some experiencing blackout conditions for up to nine hours.

Electricity was cut across the Alice Springs region around 2:30pm yesterday and was not restored in some areas until 10:47pm.

Just like that: 200 years of gas for Australia discovered in NT

Australia now has 200 years of frackable gas to add to the 300 years of coal

And yet we are still buying Chinese solar panels. The big question is how much of our our gas and coal can we use before nuclear energy makes them irrelevant? h/t GWPF

In April the Northern Territory lifted its ban on fracking. The Beetaloo basin may have a whopper 50 to 100 trillion cubic feet of gas, and it appears to be a “stacked play” in layers (like Texas).  To put that in perspective, the largest gas project in Australia in the Bass Strait has produced 8 trillion cubic feet so far with another 7 trillion to go. Shale turned the USA from an energy dependent state to the worlds largest fossil fuel producer.

The Northern Territory holds enough natural gas to supply Australia for 200 years-plus and is comparable to the shale resources that have revolutionised the US energy sector, Resources and Northern Australia Minister Matt Canavan says.

Senator Canavan described Beetaloo, located southeast of Katherine, as “a world class shale resource [...]
