National Grid ESO will launch a new service to help balance the power grid this week. Dynamic Containment is designed to bring frequency back to 50Hz as fast as possible. Maintaining system frequency is an increasing challenge for the Electricity System Operator as large thermal plant retires or runs less often, and more renewables come onto the power system. Without lots of big spinning turbines from thermal power systems to help provide inertia as a bi-product, the effect of lower system inertia is that frequency can change much more quickly – a small wobble can have large impacts if not quickly addressed. So the ESO has developed Dynamic Containment, a service that kicks in after frequency has started to deviate. It will become a 1GW day ahead marketplace that brings procurement closer to real time.
