Dynamic Regulation (DR)

Dynamic Regulation (DR) is a pre-fault service designed to slowly correct continuous but small deviations in frequency. The aim is to continually regulate frequency around the target of 50Hz.

Currently, the electricity system is experiencing lower inertia and larger, more numerous losses than ever before. Faster acting frequency response products are needed because system frequency is moving away from 50Hz more rapidly as a consequence of imbalances.

The ESO aims to deliver a new suite of faster-acting frequency response services to support our operations as the electricity system is decarbonised. Dynamic Regulation alongside Dynamic Moderation will complete the suite of new end-state services that will mitigate this risk following the launch of Dynamic Containment.
