Dunstan Thomas is on the National Grid list of accredited suppliers of EDT systems for participants in the UK electricity market. The Genstar4 EDT module has successfully completed all National Grid’s Business Process Interface Tests (BPITs) and has an EDT (Trading Point) Qualification test certificate for both the current BM system and the forthcoming EBS (Electricity Balancing System) replacement software system.
National Grid is replacing the existing Balancing Mechanism system with the ‘Electricity Balancing System‘ (EBS) for balancing electricity supply and demand. The new EBS system is envisaged to go live in late 2016 making use of current EDT and EDL interface mechanisms and file formats.
The 2nd phase of the EBS implementation is known as EBS* and will require changes to the existing EDT and EDL interfaces used by market participants (envisaged in 2017). The new interfaces are currently known as EDT* and EDL* and will use web service based communications. The number of ramping rates supported by EBS* will also increase from three to ten.
Dunstan Thomas completed informal conformance testing against EBS in 2012 and completed formal testing and certification in September 2016.
Dunstan Thomas is a member of the National Grid Energy Balancing System IT Subgroup and provides regular updates to our customers on the issues discussed by the group. As a member of the group we keep abreast of the latest changes and information needed to develop the new EDT*and EDL* interfaces.
Participants in the UK electricity market require an accredited EDT module to submit pre-gate closure information to the System Operator (SO), National Grid (NGET). This enables the party, be it a generator or demand side participant, to send data to be able to participate in the balancing mechanism.
With EDT you can:
EDT is an FTP connection between a BSC Party, or their agent, and National Grid. All communications between the BSC Party and National Grid are assigned a sequence number which must be kept in the correct order. Each submission by a participant is either acknowledges (ACK) or rejected (NACK) by National Grid. The Genstar4 EDT module handles this and allows the user to change the sequence number when necessary and to track the status of all submissions to National Grid.
