Development of the blueprint follows warnings from the body that runs the market — the Australian Energy Market Operator (AEMO) — that the power system could become unstable as early as 2022 as the amount of renewable energy threatened to overwhelm demand.
At the core of AEMO's concerns was the way in which vast quantities of rooftop solar power flooded uncontrolled on to the system during the middle of the day, often forcing out other generators such as gas and coal-fired plants.
AEMO said while the solar panels supplied emissions-free energy, it was the conventional generators that provided the "firming" services which helped to keep the grid stable.
