The Single Markets Platform (SMP) is being designed to help NGESO become a better buyer of ancillary services through the transformation of the user experience.

The aim of the SMP is to provide frictionless access to ESO markets initially starting with the new and enduring day ahead Frequency Response markets. 

The foundational release of SMP went live on the 10 February 2022 and facilitates the onboarding process for new and existing participants for Dynamic Containment, Dynamic Moderation and Dynamic Regulation.
