Dunstan Thomas is on the National Grid list of accredited suppliers of EDL systems for participants in the UK electricity market. The Genstar4 EDL module has successfully completed all National Grid’s Business Process Interface Tests (BPITs) and has an EDL (Control 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 an ‘Electricity Balancing System‘ (EBS) for balancing the real-time electricity supply and demand. The new EBS system is envisaged to go live in late 2016 using the existing EDT and EDL interface mechanisms.
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. National Grid has pledged to support the first phase EBS interfaces for up to 5 years following EBS go-live.
Genstar4 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 EDL module to communicate real time with the System Operator (SO), National Grid (NGET). This enables the participant, be it a generator or demand side participant, to receive instructions from NGET and to submit real time changes to dynamic parameters back to NGET.
With EDL you can:
The Genstar4 EDL module also allow the energy management centre (EMC) to have an overview of EDL instructions sent or received for all the plant within its portfolio, whilst allowing the unit operators to accept and reject only the instructions received for their unit.
