Energy market commission says electricity grid increasingly unstable

Instability attributed to changes in power mix that can leave grid at mercy of the weather

The Australian Energy Market Commission says the national electricity grid is becoming more unstable, with 11 incidents in 2016-17, up from seven the year before and four the year before that.

The instability is attributed to changes in the power generation mix, with thermal, synchronous generators leaving the system in favour of more renewable capacity, which can leave the grid at the mercy of the weather.
