Electronic Data Transfer – EDT

What does EDT do?

Participants in the UK electricity Balancing Mechanism require a Trading Point (TP) to manage their Balancing Mechanism Units (BMUs) and an accredited EDT software system to submit pre-gate closure information to the National Grid ESO. This enables the party, be it a generator, Virtual Lead Party (VLP) or demand side participant, to send data to be able to participate in the balancing mechanism and TERRE.

EDT Supports:

  • Submission of day ahead dynamic plant characteristics e.g. NDZ, NDO, NDB and ramp rates to NGE.
  • Submission of bid offer data (BOD) and TERRE bids to NGE to enable participation in the balancing mechanism and TERRE.
  • Send availability schedules (MEL) to NGE.
  • Send day ahead physical notifications (PNs) to NGE. These notifications, if not updated, will become the final physical notification (FPN) for the BMU.
  • Submit ETR and Remit data to the NGE MODIS system.

For larger participants, a fixed MPLS line (and backup line) is required for EDT. The EDL circuit is the responsibility of the participant and significant lead times of over six months are to be expected for its installation (by Vodafone). Dunstan Thomas provides a hosted service for EDT with its Genstar4 software which includes pre-installed EDL and EDT lines.

Wider Access

As part of NGE’s Wider Access initiative, EDT communications are now supported via API for participants with a single site less than 100MW or a portfolio less than 300MW. Above these thresholds requires fixed line EDL communications.

This method of access is aimed at Virtual Lead Parties (VLPs) and smaller participants.

Genstar4 provides support for Wider Access APIs.

EDT accreditation

Dunstan Thomas is on the NGE list of accredited suppliers of EDT systems for participants in the UK electricity market. The Genstar4 EDT module has successfully completed all NGE’s Business Process Interface Tests (BPITs) and has an EDT (Trading Point) Qualification Test Certificate.

Genstar4 will also be certified for TERRE messages in 2020.

What kind of link is EDT?

EDT is a fixed MPLS line between the participants Trading Point and NGE.

EDT operates using an FTP connection between a BSC Party, or their agent, and NGE. All communications between the BSC Party and NGE are assigned a sequence number which must be kept in the correct order. Each submission by a participant is either acknowledged (ACK) or rejected (NACK) by NGE. The Genstar4 Power Scheduler module automatically maintains sequence number integrity and tracks the status of all submissions to NGE.
