Interesting article about the issues that need to be sorted in order to get to 100% renewables.
Nice to see the Liberal South Australian government is having a crack and tackling the issue head on.
" The South Australia Liberal government has announced a new energy package to ensure the state can reach its target of net 100 per cent renewables by 2030, including a commitment to fast-track a new transmission line to NSW and allowing the market operator to effectively switch off rooftop solar to protect the grid.
The new South Australia Energy Plan has been prompted by new analysis by the Australian Energy Market Operator, which suggests that the growing amount of rooftop solar will mean that the state grid could experience “zero operational demand” within the next one to three years – much earlier than expected – and it needs to be able to “shed” rooftop solar on rare occasions to avoid the risk of a state-wide blackout.
The AEMO report says that South Australia is the first gigawatt scale power system in the world to approach zero operational demand due to the growth of distributed resources. This had been expected to occur by 2025, but the increasing growth of rooftop solar – now around 200MW a year – means it could happen much earlier, with big risks to the grid if not properly managed.
