We keep track of breakdowns at the National Electricity Market’s fossil fuel powered stations.
Reliability Watch is monitoring breakdowns at fossil fuel powered stations across the National Electricity Market. As these stations get older, they are more likely to break down, especially in hot weather, when demand is usually high. We need to keep a close eye on our electricity system’s reliability, because what we can measure, we can improve.

Reliability key to keeping the energy transition on track
Reliability Watch monitors the National Electricity Market’s fossil fuel power plants for breakdowns. We started with summer 2024 - 2025 (October - March) because fossil fuel powered stations are more likely to breakdown in hot weather, when demand is also likely to be high.
