SONI has today published a consultation paper on the Day-ahead System Services Auction (DASSA) Product Review & Locational Methodology.
As part of the ongoing work to develop Future Arrangements for System Services, SONI and EirGrid have developed proposals for the design of the DASSA.
These proposals are based on the High-Level Design set out by the SEM Committee (SEM-22-012) and look to review the reserve products to be procured in the DASSA, and the development of a locational methodology that would support RES-E (electricity from renewable generation sources) objectives.
Responses to the consultation, preferably structured in line with the specific questions raised in this paper (listed below), should be submitted via the SONI consultation portal by 18 July 2024, 17:00.
Please note your response will be publicly available for viewing on the portal. If you require your response to remain confidential, please clearly state this in your response.
An online industry workshop, at which the TSOs will present our proposals for interested parties is scheduled for June 19th from 9:30am. to 11:30am.
Q.2 Are there additional considerations that you believe have not been fully explained or examined yet? Please elaborate on what you consider needs more detailed information.
Q.3 Do you agree with our conclusions that we need increased capabilities in FFR speed of response?
Q.4 Do you agree with our assessment of the need for downward reserve product definitions as part of the DASSA procurement process and to align with EU requirements?
Q.5 Do you agree with the quality aspects that we have outlined? Are there additional system need based quality aspects you believe are worthy of further consideration?
Chapter 4 Changing capabilities of reserve providers
Q.6 Do you consider that we have accurately captured the generic characteristics of reserve providers? Are there additional considerations that you recommend we include?
Chapter 5 Reserve Product Review
Q.7 Do you agree with our assessment that the proposed DASSA reserve products will help achieve greater alignment with EU requirements?
Q.8 Do you have any views on the outlined requirements on frequency trigger capability, response trajectory capability, reserve step size & reserve step triggers for Upward reserve products? Please elaborate on any technical concerns you may have with regard to these proposals.
Q.9 Do you consider the standard definition of the FFR product which requires delivery of response between 1s-10s as proposed provide sufficient certainty for asset operators and investors?
Q.10 Do you consider our recommendations to require procurement of sub-categories of faster response FRR with full activation times of 150ms; 300ms & 1 sec enable industry providers to have sufficient incentives to bid in the auction structures? Are there additional aspects you consider should be included in the definition? Please elaborate in your response on aspects you consider need to be included.
Q.11 Do you agree with our proposal to remove the distinction between synchronised and desynchronised replacement reserve products (current DS3 definitions) to better reflect a changing service provider mix and to achieve better alignment with EU requirements? Please elaborate in your response if you have detailed concerns.
Q.12 Do you have any views on our consideration of procurement of a bundled upward reserve product? Please outline your views and any concerns you may have on this proposal.
Q.13 The TSOs recognise the potential provision of Upward dynamic reserves with discrete reserve step-sizes. We are not proposing this type of response as part of this DASSA Reserve Product Review. Please outline your views and any concerns you may have on this proposal.
Q.14 Do you have any views on the outlined requirements on frequency trigger capability, response trajectory capability, reserve step size & reserve step triggers for Downward reserve products? Please elaborate on any technical concerns you may have with regard to these proposals.
Q.15 Do you consider our proposed downward reserve definitions are appropriate for an evolving system? Are there alternative definitions that you would recommend to ensure efficient service procurement and provision?
Q.16 Do you have any views on our consideration of procurement of a bundled downward reserve product? Please outline your views and any concerns you may have on this proposal.
Q.17 The TSOs recognise the potential provision of Downward dynamic reserves with discrete reserve step-sizes. We are not proposing this type of response as part of this DASSA Reserve Product Review. Please outline your views and any concerns you may have on this proposal.
Chapter 6 Locational requirements
Q.18 Do you agree with our assessment of the locational considerations for the reserve services? Are there additional aspects that you consider may be valuable to include?
Chapter 7. Reserve product scalars
Q.19 Do you agree with our proposals on the removal and replacement of the above scalars? Are there aspects that you believe still warrant a scalar based approach in an auction-based procurement process. Please provide a detailed response on what you consider would be appropriate and how this would enable more efficient procurement outcomes.
Chapter 8. Next steps
Q.20 Are there aspects that have not been covered in this paper that you feel need further consideration during the final product definition phase? Please provide a detailed response on any recommended additional considerations.
Q.21 As part of a future Product Review the TSOs will be conducting analysis that will help inform the product definitions of non-reserve System services and potentially new products. Do you have any recommendations on what needs to be included in the work programme for such future Product Reviews?
