    Chart of the week | Cha-Cha Slide: COVID-19 & falling levels of inertia

    The level of inertia on the system is a key contributor to electricity system stability. Inertia is an attribute of the system related to the energy stored in the rotating motors of synchronous generators. It prevents system frequency from falling too quickly after a frequency disturbance (e.g. a generator trip)....
