Hilarious, that last graph really shouldve been in this puff piece article.
Quadruple the energy price in return for replacing coal plants with junk batteries.
Installing a battery in South Australia did not lead to to a quadrupling of national energy prices. The cost of energy globally has shot up since 2020, and Australia's spot prices are based on the global market.

Energy independence in the form of renewables is now more advantageous than ever. Tethering your economy to global price hikes like this is a vulnerable position to be in.

The graph shows the cost of energy globally at worst doubled. So Australia’s increase is double the global average.

Also renewables were supposed to decrease the exposure to such global price fluctuations, or at least act as a backstop for the marginal kWh.

Apparently the backstop is still much higher. And batteries do not generate energy.

Australia's spot prices aren't based on the global market.

They are based on the (Australian) national energy market (NEM) which sets price based on supply and demand across South Eastern Australia (WA and NT aren't in the NEM)

The big jump in the last couple of years coincides with the war in Ukraine and high international gas prices.

The government response has been to pressure gas producers to reserve more for the domestic market.
