DS3 Programme

Our Delivering a Secure Sustainable Electricity System (DS3) programme seeks to address the challenge of integrating world-leading levels of 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).

Ireland’s binding EU target is for 16% of the country’s total energy consumption to come from renewable energy sources by 2020. In order to achieve this there is a target for 40% of generation to come from renewable sources, with the same target in Northern Ireland.

The aim of the DS3 Programme is to meet the challenges of operating the electricity system in a secure manner while achieving these 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. Achieving this level of renewable integration on a synchronous system is unprecedented and presents significant challenges for the real-time operation of the power system.

So far the DS3 programme has enabled EirGrid to increase levels of renewable generation possible on the system at any given time from 50% to 60%, with the aim of increasing this incrementally to 75% over the coming years.

The DS3 programme has bought together numerous important strands of work to facilitate Ireland’s and Northern Ireland's ambition to produce 40% of electricity from renewable sources. This exciting and challenging programme is built on three pillars, each vital to its success. These are:

  • System Performance
  • System Policies
  • System Tools

Across these three pillars we are fundamentally reviewing how we do things across the electricity industry to ensure policies, incentives, standards and tools are fit for purpose in a system with world-leading levels of renewables.

For more on the DS3 Programme, read our information brochure here.

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 a range of services from as wide a pool of generators and market participants as possible. This includes the development of financial incentives for better plant performance. This should mean savings for the consumer and an increase in the levels of renewable energy we can accommodate at any given time.

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).
