The dynamics of balancing electricity supply and demand on the grid have been deeply affected by the coronavirus pandemic, but it’s certainly not the only reason why the UK’s electricity system operator is introducing a new service called Dynamic Containment. What is it and why is the UK already replacing its firm frequency response (FFR) and other ancillary services?

More electricity storage and longer durations will be needed for the UK to meet net zero, according to electricity system operator National Grid ESO’s latest modelling.

Barriers have been removed allowing for battery storage projects five times the size as the current limit in Britain, in a move hailed as a “significant, positive and well-timed” step.
