20.12.18 EirGrid and SONI 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 2 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.

 

17.01.19  Following feedback from industry EirGrid and SONI have extended the deadline for responses to the DS3 System Services Protocol Document consultation from 18th January to 30th January.  The Protocol document specifies the compliance requirements which a service provider must satisfy before being paid for DS3 System Services. In addition, it specifies the Performance Monitoring procedures to be applied. It also contains operational requirements, specifying minimum standards that Providing Units must meet. 

This consultation paper outlines the proposed amendments to the DS3 System Services Protocol document – Regulated Arrangements, Version 1.0, published 12th December 2017 which is available here.  The marked up version of the Protocol document which accompanies this consultation is available here.  The purpose of the consultation paper is to provide stakeholders with information about our proposals and a guide to the consultation process.

Responses to the consultation, preferably structured in line with the specific questions raised in this paper (a questionnaire template for responses is available here), should be sent to DS3@eirgrid.com or DS3@soni.ltd.uk by 30 January 2019.

*Please note that the initial version of the protocol document indicated that it only applies to the Regulated Arrangements. This is not the case, and the document has now been updated to reflect that it also covers the Fixed Contracts (Volume Capped) arrangements.

If you have any queries relating to the event, please email DS3@EirGrid.com or DS3@soni.ltd.uk

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.

16.01.2018 The EirGrid and SONI Marked Up DS3 System Services Agreements (Regulated Arrangements) are now available to view. These document are marked-up/redline versions of the DS3 System Services Agreements (Regulated Arrangements) relative to the DS3 System Services Framework Agreements (Interim Arrangements).

14.12.2017 The OJEU notice for the DS3 System Services – Regulated Arrangements Volume Uncapped in now available on the eTenders website, Applicants are invited to submit a tender for this contract in accordance with the instructions set out in the Request For Proposal (RFP), which you can find by registering and logging in here.

Reference details for the tender are as follows:

  • eTenders Ref: RFT 127775
  • EirGrid Tender Ref: ENQEIR583 – DS3 System Services – Volume Uncapped

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.

 

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.

 

 

 

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.

 

 

 

 

26.09.17 EirGrid and SONI have today published a consultation paper on the DS3 System Services Regulated Arrangements Contracts. 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).

The SEM Committee directed that DS3 System Services Regulated Arrangements be established for 1 May 2018. This consultation paper outlines the contractual arrangements that we are proposing to put in place for DS3 System Services Regulated Arrangements. It is accompanied by the draft Ireland Regulated Arrangements Agreement and draft Northern Ireland Regulated Arrangements Agreement  which are referenced in the consultation paper. The paper also contains more information on the proposed procurement process. The purpose of the consultation paper is to provide stakeholders with information about our proposals and a guide to the consultation process.

Responses to the consultation, preferably structured in line with the specific questions raised in this paper (a questionnaire template for responses is available here and a spreadsheet for more detailed legal comments is available here), should be sent to DS3@eirgrid.com or DS3@soni.ltd.uk by 17 October 2017.

24.07.17 EirGrid and SONI have today published a recommendations paper on the DS3 System Services tariff rates to apply for the period 1 October 2017 through 30 April 2018. The tariff rates set out in the recommendations paper have been approved by the SEM Committee. 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 May 2017, we published a consultation paper outlining the DS3 System Services tariff rates that we were proposing to apply to the existing Interim Framework Agreements for the 11 services that are being extended to the end of April 2018. Following consideration of the responses to the consultation, we submitted a recommendations paper to the SEM Committee. The Regulatory Authorities reviewed the TSOs’ consultation paper, stakeholder responses and the TSOs’ recommendations paper. Following this review, the SEM Committee published a decision paper on 21 July 2017 approving the tariff rates as set out in the TSOs’ recommendations paper for the “roll-over contract” period from 1 October 2017 through 30 April 2018. We are now publishing the recommendations paper while a summary of the non-confidential responses to the consultation is available to view here.

 

 

 

04.07.17 EirGrid and SONI have today published two consultation papers on (1) the DS3 System Services Enduring Tariffs proposed to apply from 1 May 2018, and (2) the associated proposed DS3 System Services Enduring 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 the Enduring Tariffs consultation paper, we set out the proposed enduring tariff framework and enduring tariff rates to apply to all 14 services following execution of the new system services contracts in May and September 2018. The Enduring Scalar Design consultation paper looks at how scalars could be implemented to incentivise flexibility, reliability, and value for money, and sets out our proposed approach on how these would be best implemented for the Regulated Arrangements. These consultation papers should be read in conjunction with each other. The purpose of the consultation papers is to provide stakeholders with information about our proposals and a guide to the consultation/feedback process.


Responses to the consultation, preferably structured in line with the specific questions raised in the papers should be sent to DS3@eirgrid.com or DS3@soni.ltd.uk by 21 August 2017. The questionnaire template for responses to the enduring tariffs consultation is available to view here and the questionnaire template for responses to the enduring scalar design consultation can be viewed here.

Following the consultations, we plan to publish decision papers in relation to Enduring Tariffs and Enduring Scalars in October 2017.

 

 

28.06.2017 EirGrid and SONI have published a decision paper on the Revised DS3 System Services Interim Performance Methodologies. The purpose of DS3 Performance Scalars is to incentivise reliable and enhanced service provision. Following feedback received on the original methodologies a consultation paper was published in April 2017. This decision paper is in response to that consultation. Details of all consultation responses can be found here for reference.

In addition to the decision paper the DS3 Interim Protocol Document has also been updated to reflect the changes in methodologies. The DS3 Protocol Document forms part of the Interim Arrangements contractual arrangements along with the accompanying Framework Agreement and the Statement of Payments. This updated Protocol Document will now take effect from the date of this publication.

In addition to the publication of the Decision Paper and updated DS3 Protocol Document a number of template documents can also be found below in respect to the query management process and performance testing application process which form part of the contractual arrangements.
