South Australia: The first big grid where rooftop solar could eliminate all demand | RenewEconomy

As South Australia energy minister Dan van Holst Pellekaan notes, the state is mighty proud of its collection of energy “firsts” – a world leader in the uptake of rooftop solar and wind energy, the host of the world’s biggest lithium-ion battery among them. But it’s the latest “first” that is putting the wind up the state government and the market operator: Within one to three years, they say, South Australia could become the first gigawatt scale grid in the world where the growing amount of rooftop solar effectively eliminates grid demand.

In Western Australia, rooftop solar is already by far the biggest generator in that grid, and within a few years could push “minimum” demand down to levels that could cause problems for the grid operator.
