Non-BM ancillary service dispatch platform (ASDP) instructions
Summary
NESO publishes real-time instruction data for non-BM ancillary services including Fast Reserve, STOR, and RDP dispatch through its ASDP system. Data is published continuously throughout the day once service providers confirm instructions. Monthly files are created only when new instructions are dispatched for these MW services.
Why it matters
This transparency measure allows market participants to observe ancillary service dispatch patterns and volumes outside the Balancing Mechanism. As such, it provides useful market intelligence for providers considering entry into these reserve markets, though it does not change the underlying procurement or pricing mechanisms.

Memo
The NG ESO publishes non-BM instruction data from our ASDP system once instructions have been confirmed by Service Providers. This information is then continuously published throughout the day on this platform. A new monthly file is only created when a new set of instructions are dispatched for non-BM Fast Reserve (FR), Short Term Operating Reserve (STOR), and Regional Development Programme (RDP) MegaWatt (MW) Dispatch services.
