The objective of the BMPS and associated documents is to provide a clear and comprehensible description of the scheduling and dispatch process. This consultation report has been prepared for the Regulatory Authorities following consultation with industry on revisions to the Balancing Market Principles Statement (BMPS).

​EirGrid and SONI (the TSOs) published a consultation paper on 10 May 2024 concerning the Harmonised Other System Charges for the upcoming tariff period, 1 October 2024 to 30 September 2025. Comments on the consultation paper were received. Having reviewed and included the responses, in this paper the TSOs propose a number of recommendations to the Regulatory Authorities (the RAs) for their consideration and approval.

This document outlines the list of all Controllable PPMs, 5MW or more on the EirGrid and SONI systems. Each unit is categorised as level (i), (ii) or (iii). The technology types are listed and identified as appropriate within the tables. This list will continue to be updated on a monthly basis.

​Presentation slides from the ESB Networks & EirGrid Joint System Operator Programme Virtual Briefing Webinar which will have taken place on Friday 14th June. It provides an overview of how the system currently works and what the drivers for change to this system are. The target audience is industry stakeholders.

This document sets out the requirements for the TSOs to issue a Market Readiness Certificate.

Wind and solar generation is treated as priority dispatch (per SONI and EirGrid licences, SEM Committee decision SEM-11-062 and subsequent mods) however it is sometimes necessary to constrain or curtail its output to maintain system security. Constraints result from power flow limitations due to the topology and characteristics of the transmission network. Constraints are applied locally. Curtailment arises due to binding all-island system wide limits such as the System Non-Synchronous Penetration (SNSP) limit or minimum inertia levels. Curtailment is applied Al-lIsland.
