System Services Future Arrangements – Phase III: Detailed Design and Implementation – Phased Implementation Roadmap for the System Services High Level Design – Consultation Paper

The SEM Committee has today, 8^th June 2023,  published a consultation paper seeking views on the Phased Implementation Roadmap for the implementation of the System Services High Level Design.

The draft phased transition roadmap proposed in this paper comprises a number of elements:

• Extending the current tariff arrangements and a phased reduction of tariff rates. 
• Early implementation of competitive procurement for reserve services, through a simplified and pragmatic process using the Layered Procurement Framework.
• This will be followed by a full implementation of the Layered Procurement Framework and the phased introduction of Daily Auctions for the full range of system services, noting that work developing these arrangements will happen in parallel.
• Phased introduction of the governance arrangements set out in the HLD, starting with those elements necessary to run the first Layered Procurement auction including the introduction of a Code and establishment of a standalone System Service charge (to recover the required revenues to cover the costs of payments to providers), and then built upon incrementally in consultation with industry.
• In parallel to the implementation of the first auction the TSOs will consult on the volumes methodology and reporting, carry out a product review, and consult on its locational methodology. It is proposed that the volumes deliverables will be prioritised. The SEM Committee expects that the product review will be sufficiently advanced ahead of the first auction to enable informed progress.

The consultation will remain open for eight weeks, closing on 3 August 2023. Workshops will be arranged during the consultation period, and bilateral engagements can be arranged at the request of stakeholders. Should stakeholders have any queries or comments please contact Dylan Ashe (dashe@cru.ie) or Lauren Skillen-Baine (lauren.skillen-baine@uregni.gov.uk). All responses should be submitted by email to both these addresses.
