Fast Frequency Reserve (FFR)Information process flow

Information Process Flow

This page describes the flow of information between BSPs, Fingrid and others.

From the BSP’s perspective, information process flow consists of the following:

  • Sending bids and receiving acknowledgements
  • Receiving reserve allocation reports and sending acknowledgements
    • Reserve allocation results are received both as a daily document as well as on the bid level.

The image below illustrates the message flows between the BSP and TSO related to the FFR market. Sequence diagram of FFR message exchanges between BSP and TSO

BSPs send bids to VAKSI via ECP/EDX, and from there VAKSI will handle FFR procurement. As a fallback solution, BSPs can additionally send FFR bids via the VAKSI web UI.
