ESO
Phase 2 Auction Trial
The auction trial is an innovation project which is procuring Low Frequency Static (LFS) and Dynamic Low High (DLH) frequency products through the EPEX SPOT Auction Platform on a weekly basis.
Latest News
18/9/20 - As promised in the Response and Reserve Roadmap issued in December 2019, we would share with you our initial findings and learnings about the Auction Trial project in a project evaluation report. The evaluation report (produced by ESP Consulting) and the ESO response letter are now available. We have now recorded a video to talk you through these two reports. Please tell us your feedback by completing this short 1-minute survey.
25/8/20 - Following the feedback we received in the Auction Trial market survey, a simplified EPEX platform user guide has now been published, please find it here.
26/6/20 - As part of the Power Responsive Summer Insights series, we have recorded a podcast on the Auction Trial. You can listen to it here.
The Low Frequency Static (LFS) service is a faster static service compared to the monthly FFR static service.
LFS Service Description:
- Trigger level is 49.6Hz
- Full response within 1 second
- Duration is 30 minutes.
The testing must be completed according to the LFS Testing Guidance in the document section below. An Independent Technical Expert (ITE) must sign off the testing. For testing to be approved NGESO must receive a completed LFS Test Certificate, the relevant data and the ITE's CV.
The Dynamic Low High service is similar to the monthly FFR Dynamic service, however there must be equal volume delivery of Primary, Secondary and High response.
Any units that are currently tested for the monthly Dynamic FFR service are able to provide DLH without re-testing.
All new units will need to follow the FFR Testing Guidance for Dynamic, this can be found here. An ITE will need to be used to sign off the testing.
