DS3 Programme

Our Delivering a Secure Sustainable Electricity System (DS3) programme seeks to address the challenges of integrating renewable generation onto our power system.

What is the DS3 Programme?

Delivering a Secure Sustainable Electricity System

In response to binding National and European targets, EirGrid Group began a multi-year programme, “Delivering a Secure, Sustainable Electricity System” (DS3).

The aim of the DS3 Programme is to meet the challenges of operating the electricity system in a secure manner while achieving the 2020 renewable electricity targets. The DS3 Programme is designed to ensure that we can securely operate the power system with increasing amounts of variable non-synchronous renewable generation over the coming years.

Ireland’s target under the EU Renewable Energy Directive (2009/28/ EC) is for 16% of the country’s total energy consumption to come from renewable energy sources by 2020. In order to achieve the 16% target the Government set a 10% renewable transport target, a 12% renewable heat target and a 40% renewable electricity target. Similarly in Northern Ireland, the Department of Enterprise, Trade and Investment (DETI) published the Strategic Energy Framework (SEF) in September 2010, which also set out a 40% renewable electricity target to be reached by 2020.

Achieving this level of renewable integration on a synchronous system is unprecedented and presents significant challenges for the realtime operation of the power system.

The DS3 Programme is made up of 11 workstreams, which fall under the three pillars of System Performance, System Policies and System Tools. Each pillar is vital to the success of the programme and to achieving the 40% renewable electricity target. The programme brings together many different strands, including development of financial incentives for better plant performance, and the development of new operational policies and system tools to use the portfolio to the best of its capabilities. Standards for wind farms and conventional plant are also being reviewed to give enhanced operational flexibility for the future. The programme involves many different stakeholders, including the Distribution System Operators (DSOs), Regulatory Authorities, Conventional Generators and Renewable Generators, as well as Government Departments.

As part of this programme, we have established an Advisory Council to ensure that the views of industry are well represented. Read more information here.

Additional information on DS3 can be found in the library section of this website.

One of the key areas in the DS3 Programme is System Services. We want to make sure that the system operates securely and efficiently, while facilitating higher levels of renewable energy. To achieve this aim, we are working to obtain services from generators and market participants. This includes the development of financial incentives for better plant performance. This should mean savings for the consumer and a reduction in the dispatch-down of wind energy for system-wide security limitations.

We produce a quarterly update on the System Services Implementation Project Plan. Read the most recent update here.

DS3 System Services Interim Arrangements Procurement

EirGrid and SONI have published the outcome of the procurement for the DS3 System Services Interim Arrangements. This includes a summary of successful tenderers and the services for which they have been contracted for both Ireland and Northern Ireland. Eleven system services were procured from service providers in Ireland and Northern Ireland under the DS3 System Services procurement process, with separate framework agreements for each jurisdiction. The Interim Arrangements became effective on 1 October 2016.

EirGrid and SONI have also published a summary of the contracted volumes for the DS3 System Services Interim Arrangements together with the forecast expenditure for the Interim Arrangements period (1 October 2016 to 30 September 2017).

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).

Consultations

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. Details on the use of these templates are described within the DS3 Protocol Document.

02.05.17 EirGrid and SONI have today published a consultation paper on the DS3 System Services Tariffs to apply for the period 1 Oct 2017 through 30 April 2018. 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).

This consultation paper outlines the DS3 System Services tariff rates that we are proposing to apply to the existing Interim Framework Agreements for the 11 services that are being extended to the end of April 2018. The purpose of this document is to provide stakeholders with information about our proposals and a guide to the consultation process. The TSOs will separately consult in July 2017 on system services volume requirements, enduring scalar designs and the regulated tariffs to apply from May 2018 onwards.

Responses to the consultation should be sent to DS3@eirgrid.com or DS3@soni.ltd.uk by 30 May 2017.

EirGrid and SONI have today published a consultation paper on changes to the DS3 System Services Interim Performance Methodologies.
