Australia Prepares for a Power Grid Without Spinning Turbines

Australia is preparing for its next step away from fossil fuels by creating a market to replace the spinning coal plant turbines that help stabilize the power grid. From a report: The government's adviser on energy policy, the Australian Energy Market Commission, is consulting on a rule change for a spot market in inertia provision, it said in a statement on Thursday. Australia's world-leading usage of wind, solar and batteries has led to "new and previously unobserved operational conditions," it said. Conventional power plants use turbines that keep revolving even when the fuel that's forcing them to move stops burning. It's a process known as inertia, which helps network operators maintain stability, smooth over disturbances in the grid and prevent blackouts. However, solar panels and wind turbines generally stop and start almost instantaneously -- hence the AEMC's call for other sources of inertia.
