The Response Market Schedule Review project aims to evaluate the potential benefits of alternative auction
timings for frequency response services. The focus is on exploring whether closer-to-real-time auctions—or
combinations of auctions across different timescales could improve market efficiency, system operability,
and participant engagement. The project will assess high-level design options for auction timing, granularity,
and delivery duration, with recommendations developed in collaboration with NESO. This work will inform
future market design decisions and support the transition to a more flexible, responsive energy system

rapid launch and growth of the market. Now the market is becoming mature, a review of procurement
structures is prudent, whether the review identifies opportunities to improve social benefit or simply confirms
that the existing arrangements are performing well.
