The SEM Committee today, 8th December 2023, publishes its decision on the System Services Future Arrangements – Phase III: Detailed Design & Implementation – Phased Implementation Roadmap. This follows a public consultation which closed on 3rd August 2023.
In summary the SEM Committee has decided the following:
• To proceed with the High Level Design as originally envisaged;
o To proceed with the Day Ahead System Services Auction (DASSA), as proposed;
o Not to accelerate or prescribe parameters for the usage of the Layered Procurement Framework, as previously proposed, at this time;
o To require the TSOs to carry out an assessment of services to be procured through the LPF, as required, and at least annually;
• To extend the Regulated Arrangements to April 2026, with a tariff review in Q1 2024;
• To implement the Phased Implementation Roadmap; and
• To establish the consultative SSFA Project Panel.
Based on the draft Phased Implementation Roadmap, the TSOs will consult on and submit recommendation papers to the SEMC in 2024 covering the following areas:
• Day Ahead System Services Auction (DASSA) Detailed Design
• First Annual Review of LPF
• Volumes Methodology
• Products Review
• Locational Methodology
• System Services Supplier Charge
• Review of Regulated Tariff Rates
Work will also commence on development of the System Services Code, with the first draft to be prepared by the TSOs, by Q3 2024, ahead of industry engagement through the Panel, later in 2024. The details of the Code will inform development of the IT solution later in 2024/early 2025. Additionally, a workstream to identify and implement necessary Licence modifications, to give effect to the Code and any other associated requirements, will commence.
The SEM Committee will invite industry associations to nominate a representative to the System Services Project Panel and will publish a terms of reference and schedule of meetings for the Panel for 2024 in the coming weeks.
