The UK’s electricity system has changed dramatically over the past decade, with renewables increasingly contributing to the energy mix. However, one thing hasn’t changed: the need for electricity supply to always meet demand.

Electrical frequency is a factor of power supply that’s carefully managed to keep a country’s lights on (find out more about exactly what it is here). Great Britain’s grid operates at a frequency of 50Hz – a deviation of more than just 0.2% can cause outages and damage grid equipment. So, when there’s a spike in electricity demand, the supply must increase to meet it.

This becomes challenging in a system increasingly dependent on intermittent renewables, like wind and solar, that are unable to generate power if weather conditions are unfavourable.
