New Dynamic Services (DC/DM/DR)

We are using the EPEX auction platform to procure DC, DM and DR. Key documents can be found below.

We hosted a webinar on the mock auction for DC, DM and DR procurement on 8 March 2022. Below is a recording of the webinar as well as the slides that we presented.

To participate in DM and DR, non-BM providers will need to communicate via an API-based interface with the ESO’s Non-BM Dispatch system, Ancillary Services Dispatch Platform (ASDP)/Platform for Ancillary Services (PAS). Testing and approval of this interface will form part of the prequalification process. 

Updated versions of the ASDP Web Services Specification and Business Logic Document can be found below.

The Web Service Specification document describes the most recent version of web services to be implemented from both National Grid ESO (PAS) system and Service Providers’ systems. It also describes the technical specifications including Web Services Description Language (WSDLs) and XML Schema Definition, methods and parameters to be used to invoke the WSDLs, connection patterns and protocols, security measures. The validations and exceptions are particular to each ancillary service and hence these will be published as a separate ‘Business Logic Document’ for each ancillary service.

Consultations

- EBGL Article 18 Dynamic Containment consultation (21/8/20). Following the consultation, Ofgem have approved the final Terms and Conditions and associated contractual documents. Alongside the Article 18 submission, NGESO also submitted an EBGL Article 26 document and a derogation related to Clean Energy Package Article 6(2), which were both approved. We submitted a letter to Ofgem following the end of the EBGL consultation which includes the consultation responses from providers.

- EBGL Article 26 Dynamic Containment consultation (Oct 20) on the use of Dynamic Containment as a specific product. In the previous consultation, Ofgem approved the proposal we submitted on this but it was on the condition that we held a full consultation in October. The consultation was open until 30 November.
