DS3 Programme - Delivering a Secure Sustainable Electricity System

The DS3 programme focuses on integrating renewable generation into our power system.

What was the DS3 Programme?

The DS3 programme was our response to national and European renewable energy targets. Ireland’s target was for 16% of our energy consumption to come from renewable energy sources by 2020.

The DS3 programme aimed to increase the amount of renewable energy on the Irish power system.

We set our sights on 40% of electricity from renewable sources on the island of Ireland by 2020.

What DS3 Achieved

By 2018, the DS3 programme had already improved renewable generation in Ireland.

It enabled the TSOs to increase instant levels of renewable generation on the system from 50% to 65%. This was a world first.

In 2021 we increased this further to 70% and in March 2022 we reached the DS3 goal of 75%. This milestone was ten years in the making since the launch of the DS3 Programme.

These increases have enabled very high levels of renewable energy. Renewable energy accounted for 43% of electricity production in 2020.

Our Programme Pillars

We achieved all of this with a focus on three key areas:

System performance
System policies
System tools

These three pillars helped to review how we do things across the electricity industry.

They ensure policies, incentives, standards and tools are fit for purpose in a system with world-leading levels of renewables.

But we are not stopping here. We are now working to gradually increase the limit over the coming years to 95%.

What Happens Next?

The main objective of DS3 was met in 2020 and surpassed by 2022. A new set of targets have been set for 2030.

Shaping Our Electricity Future has taken over from DS3.

DS3 Advisory Council

The DS3 Advisory Council was established in 2011 to provide a forum to discuss issues which may impact on the success of DS3.

The council consisted of experts from across the power industry, including representatives from academia and industry across Ireland, Northern Ireland and Europe. Meetings were held approximately every four months from 2011 until September 2021.

The DS3 Advisory Council has now been superseded by the SOEF Advisory Council.

EirGrid and SONI have also published a summary of the contracted volumes for the DS3 System Services Regulated Arrangements.

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).

DS3 System Services – Consultation on DS3 Tariffs 2024 and SEM-C decision

Update 11 September 2024: EirGrid and SONI published back in March 2024 a consultation paper on DS3 System Services Tariffs. Following this consultation process and today, the SEM Committee has published the System Services Tariff Review Decision Paper SEM-24-065 (SEM-24-065 System Services Tariff Review Decision Paper | The Single Electricity Market Committee (semcommittee.com)) that states:

• TSS scalars to be reduced from October 2024. From October 2024, the TSS should be reduced to 4 (as opposed to 6.3), when SNSP > 70% and to 2.25 (as opposed to 4.7), when SNSP > 60%. From October 2025 further reductions in the TSS and tariff rates may occur, subject to a review of the impact from the first reduction, in relation to service availability relative to system needs.

• Tariff rates will remain at the current rates.

• Procurement of FFR – TOR2 services will continue after Gate 11. However, a request to conduct a risk assessment, around the option to close the procurement of FFR-TOR2, after gate 11, has been placed for the TSO to ellaborate.

• The TSOs will continue to monitor the effectiveness and costs of the tariff arrangements and report quarterly to the RAs, and, if appropriate, recommend revisions to current tariff rates and/or associated scalars.

DS3 System Services – Indicative 2030 Volumes

EirGrid and SONI 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, EirGrid and SONI 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.

16.10.19 EirGrid and SONI have today published the outcome of the procurement for the DS3 System Services Regulated Arrangements Volume Uncapped – Gate 1. This includes a summary of successful tenderers and the services for which they have been contracted for both Ireland and Northern Ireland.

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.

Volume Capped Procurement Outcomes

03.10.2019 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

Scottish Power 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.

DS3 System Services – Protocol Clarification – Frequency Events and performance assessment of POR, SOR, TOR1 and FFR

Recently the TSOs have received queries on the performance assessment of certain reserve services as they relate to DS3 System Services; the purpose of this note is to provide clarification to some of these queries.

To begin the TSOs would like to point out that the established methodology for performance assessments of the reserve services POR, SOR and TOR1, is that these service are assessed for all events where the frequency falls through 49.5 Hz.

In the DS3 System Services Protocol a “Frequency Event” is defined as “an occasion when the Power System Frequency falls through 49.5 Hz. The start of the Frequency Event is referred to as time zero (T=0 seconds) and is timed from the Frequency falling through the Reserve Trigger. The Frequency Event ends when the Frequency rises back above 49.8 Hz”.

For the avoidance of doubt we would like to clarify that the reason a frequency event is deemed to ‘end’ by definition at 49.8 Hz, is to differentiate that event from the start of any subsequent frequency event (i.e. multiple frequency events). In addition, by way of clarification, in the case of POR, SOR, TOR1 and FFR a performance assessment for each of these services is made for all frequency events where the power system frequency falls through 49.5 Hz, and is not bound by the ‘end’ of the frequency event as defined in the protocol. The data points used in the performance assessment of these services is described further below.

Data-point used for Assessment of Primary Operating Reserve (POR)

The assessment of POR performance is carried out at a point in time corresponding to the Nadir Frequency during the time range of T+5 to T+15 seconds, i.e. the POR Period. If the Frequency Event Nadir occurs before the start of the POR Period the POR performance will be assessed at the nadir frequency between T+5 to T+15 seconds. Asynchronous units are assessed in the same manner (albeit without an Inertial response credit).

Data-points used for Assessment of Secondary Operating Reserve (SOR)

The assessment of SOR performance is carried out during the entire SOR time range of T+15 to T+90 seconds, i.e. the SOR Period. The average provision of reserve over all data-points in this period is used in the SOR assessment.

Data-points used for Assessment of Tertiary Operating Reserve 1 (TOR1)

The assessment of TOR1 performance is carried out during the entire TOR1 time range of T+90 seconds to T+300 seconds, i.e. the TOR1 Period. The average provision of reserve over all data-points in this period is used in the TOR1 assessment. If the average Frequency over the first 30 seconds of the TOR1 Period has been greater than 49.8 Hz then the performance event will not be assessed and a N/A Data Record will be applied to the event.

Data-points used for Assessment Fast Frequency Response (FFR)

The assessment of FFR performance is carried out following the Frequency passing through the Reserve Trigger for the Providing Unit at time T=0. The assessment of FFR performance is carried out over all data-points during the entire FFR timeframe from T=0 to the end of the FFR Period i.e. to T+10 seconds. An additional calculation for FFR is conducted over all data-points in the period T+10 seconds and T+20 seconds.

DS3 System Services – Decision – DS3 System Services Regulated Arrangement Contracts

12.12.17 EirGrid and SONI have today published a DS3 System Services Contracts for Regulated Arrangements Recommendations Paper. 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).

One of the central workstreams included in the DS3 System Services project plan is – Contract Design. The objective of this workstream is to design legal contracts for the procurement of the 14 DS3 System Services. The SEM Committee directed that DS3 System Services Regulated Arrangements be established for 1 May 2018 ahead of the DS3 System Services Competitive Arrangements.

In this paper, we are presenting our recommendations on the contractual arrangements for the DS3 System Services Regulated Arrangements. The contractual principles on which this decision is based have been approved by the SEM Committee.

The decision follows a consultation held by EirGrid and SONI in September 2017. The non-confidential responses to the consultation are available to view here. In addition, responses to specific legal comments on the DS3 System Services Agreements are available here.

The paper is accompanied by the DS3 System Services Agreement (Ireland), DS3 System Services Agreement (Northern Ireland ), DS3 System Services Agreement (Northern Ireland – Intermediary version) and the DS3 System Services Protocol document.

EirGrid and SONI are also publishing three supplementary documents related to the DS3 System Services Volume Uncapped procurement process, namely the DS3 System Services Proven Technologies List, the DS3 Performance Measurement Device Standards for Fast Acting Services and the DS3 Systems Services New Signals Requirements.

DS3 System Services – Qualification Trials – Process Outcomes and Learnings 2017

03.11.17 EirGrid and SONI have today published a report on the Outcomes and Learnings from the DS3 System Services Qualification Trials Process. 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).

As part of the Delivering a Secure Sustainable Electricity System (DS3) Programme, the Qualification Trials Process (QTP) commenced in March 2017. The Qualification Trials Process aims to provide potential system services providers with an opportunity to demonstrate the capabilities of technologies that have not previously delivered system services on a system with similar characteristics to that of the all-island system which we operate. It is the mechanism through which we are managing the transition to a wider portfolio of system services providers.

The trials conducted during 2017 aimed to identify operational complexities associated with new technologies or services, develop understanding of these, and suggest solutions on how to integrate these technologies into our processes and systems. The trials consisted of fifteen individual technology trials across twelve separate Providing Units. Following the completion of the Qualification Trials for 2017, we have identified twenty six findings. These findings will inform system services product design decisions, procurement and contractual arrangements, as well as other TSO systems and processes. The rationale for each of these findings is presented in the report.

DS3 System Services – Recommendation – DS3 System Services Tariffs and Scalar Design

23.10.17 EirGrid and SONI have today published two recommendations papers on (1) the DS3 System Services Tariffs for Regulated Arrangements to apply from 01 May 2018, and (2) the associated recommended DS3 System Services Scalar Design. 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).

In July 2017 we held two consultations on our proposed tariff framework and scalar designs to apply to all 14 services following execution of the new system services contracts in May and September 2018. We received 23 stakeholder responses to each consultation. Following consideration of the responses to the consultations, we have developed two recommendations papers. In the DS3 System Services Tariffs for Regulated Arrangements Recommendations paper, we set out our recommendations in relation to the tariff framework to apply for the period from 1 May 2018. The DS3 System Services Scalar Design recommendations paper examines how scalars could be implemented to incentivise flexibility, reliability and value for money. The paper sets out our recommended approach as to how these would be best implemented for the Regulated Arrangements.

The two recommendations papers have been submitted to the SEM Committee to inform their decision on the various elements of the design. In that context, the SEM Committee’s decision paper will set out the final decisions on the design (both tariffs and scalars) to be implemented by the TSOs. The SEM Committee decision on certain elements of the design may differ in parts to our recommendation. The TSOs will assess the final SEM Committee decision and develop a plan to implement the various aspects of the arrangements as soon as possible.

A summary of the non-confidential responses to the Regulated Tariffs consultation is available to view here and a summary of the non-confidential responses the Scalar Design consultation is available to view here.

DS3 System Services – Consultation – Regulated Arrangements Contract
