Can AEMO control rooftop solar?

But AEMO said rooftop solar was now such as major force in the electricity system, it could no longer be hands-off in its approach to output in certain, extreme conditions. "AEMO can, and does, control large scale generation to manage security limits through dispatch in the electricity markets," it wrote.

Does AEMO have a'solar cut-off'?

It’s a long history, which details the lack of transparency and accountability in AEMO’s approach to controlling rooftop solar, where it is acting as judge and jury and having state bodies act as executioner through blunt ‘solar cut-offs’.

Are 'emergency backstop' powers needed for rooftop solar?

(ABC News: Rhiannon Shine) The Australian Energy Market Operator wants "emergency backstop" powers to switch off or turn down rooftop solar systems in every state. AEMO says the powers are needed by next year for extreme situations as it grapples with ever-increasing amounts of rooftop solar output.

Should aemo'reduce' rooftop solar?

And, for AEMO, that's a worry. The agency fears the amount of conventional generation providing those security and stability services — and able to step in when the sun stops shining, for example — is falling to critically low levels. Hence it says powers are needed to "reduce" some of that excess rooftop solar at certain times.

Can AEMO predict total generation from rooftop solar?

Lucky for AEMO, total generation from rooftop solar is not too hard to predict. As a cloud passes over your house, it moves away from someone else’s, kind of like the toaster example. We combine consumer demand and rooftop solar into a measurement called “operational demand” - the demand that big generators need to meet.

Can rooftop solar systems be throttled back?

One of the levers at their disposal would be the backstop provisions, which would allow rooftop solar systems to be throttled back to stop sending excess energy to the grid, or switched off entirely. AEMO says it would be up to states and network providers to use the emergency powers. (ABC News: Chris Gillette)
