15.12.2021 SONI and EirGrid held a webinar to provide an introduction to, and overview of, our proposed Low Carbon Inertia Service consultations and procurement plans.
SONI and EirGrid recently conducted analysis on indicative System Services volumes and requirements for 2030 based on three illustrative portfolios to support the work being undertaken by the regulatory authorities on the High-Level Design (HLD) of the Future Arrangements. The reason for developing three portfolios is to demonstrate that the System Services needed to operate the power system at very high System Non-Synchronous Penetration (SNSP) levels could be provided by a range of technologies. The portfolios were developed solely for the purpose of the analysis undertaken and do not represent desired, expected or optimal portfolios.
This paper summaries the results of the preliminary analysis undertaken and indicates the system services capabilities that could be delivered to enable operation at high SNSP levels provided that the right investment signals are given. Additional work on system services volumes and requirements will be undertaken in 2022 and stakeholders will be kept up to date on the outcomes from this further analysis either through a revision of this paper or through publication of additional documents. In addition, SONI and EirGrid are actively engaging with the regulatory authorities on the topic of system services volumes and the outcome of these ongoing discussions will be reflected in future publications.
SONI and EirGrid have today published updated DS3 System Services Tariff Rates as approved by the SEM Committee in a letter dated 23rd November 2021. This follows an industry consultation process conducted by SONI and EirGrid as directed by the Regulatory Authorities on the management of the overall System Services budget.

The DS3 System Services Expenditure Note in full can be found here.
23.03.2021 In November 2020, SONI and EirGrid held a DS3 System Services Protocol workshop. A number of topics were discussed including the removal of the Primary Operating Reserve (POR) Inertia Credit from the assessment of POR performance.
The TSOs have listened to the feedback from industry received at the workshop and from one to one meetings with stakeholders. We would like to inform industry in advance of the next DS3 Protocol consultation that the removal of the POR inertia credit will not be included in the scope of changes; however will continue to be reviewed for future iterations.
We had previously stated we would publish a consultation in March, however, this has been delayed as we seek to ensure we have explored all options in improving the Ramping assessment methodology.

Twelve system services were procured from service providers in Ireland and Northern Ireland under the DS3 System Services procurement process, with separate agreements for each jurisdiction. The Regulated Arrangements became effective on May 1st 2018.
EirGrid and SONI have also published a summary of the contracted volumes for the DS3 System Services Regulated Arrangements together with the forecast expenditure for the period October 1st 2019 to September 30th 2020.
The aim of DS3 System Services is to put in place the correct structure, level and type of service in order to ensure that the system can operate securely with higher levels of non-synchronous renewable generation (up to 75% instantaneous penetration).
EirGrid and SONI are delighted to announce the outcomes of the Volume Capped procurement process. This procurement process, one of the first of its kind globally, was put in place to ensure the provision of high-availability reserve services to the all-island system, and attracted a high level of interest. These services will assist Ireland and Northern Ireland in ensuring we can securely operate the power system with increasing amounts of variable non-synchronous renewable generation as we work towards decarbonising the electricity sector. They form part of the overall DS3 programme, which has already enabled the island to achieve record levels of instantaneous operation of variable renewables for a single synchronous electricity system.
The tendering process was competitive, attracting bids for 18 service providers. Of these, three were successful, providing 110 MW of Volume Capped services in total. All of the successful projects were solid-state batteries located in Ireland and received their connection offer through ECP-1. The date of dispatch of the Contract Award Notice to OJEU was 1st October 2019. The successful tenders are summarised below:
Providing Unit |
Service Provider |
Contract Size |
Gorman Energy Storage Station |
ScottishPower Renewables (UK) Limited |
50 MW |
Porterstown Battery Storage Facility |
Porterstown Battery Storage Limited |
30 MW |
Kilmannock Battery Storage Facility |
Kilmannock Battery Storage Limited |
30 MW |
The estimated total value of these contracts is around €6 million per year, totalling approximately €38 million for the lifetime of the contracts. This successful outcome represents significant savings for the end user. By way of comparison, if the equivalent level of services were procured through the Volume Uncapped process, the value of the contracts would be approximately €210 million.

20.12.18 SONI and EirGrid have today published the DS3 Programme Transition Plan Q4 2018 – Q4 2020. The document provides an update to the structure of the DS3 Programme, moving away from an 11 workstream structure to two workstreams focused on future increases in System Non-Synchronous Penetration (SNSP). A recent review of this previous workstream structure, and the associated plans, has shown that several of the workstreams are complete and can therefore be closed. This document contains closeout statements for these completed workstreams, including work completed and impact of the workstream on the overall DS3 Programme objectives. The remaining workstreams will be transitioned into the new DS3 Programme plan that will adopt a project milestone and deliverable approach focused on delivering 70% SNSP and 75% SNSP.
