Systems Services to Support Renewables

In order to prepare for a greater penetration of renewable generation in the Irish market, the incumbent TSOs set up a programme called “Delivering a Secure Sustainable Electricity System” (DS3) to ensure that the market and transmission network is able to accommodate these changes. In particular, this has impacts upon the needs for ancillary services and the way in which they are procured. ESP Consulting was engaged with the two Irish Regulatory Authorities in the development of associated policy design, with activities including:

  • Modelling of the market need for ancillary services and review of the TSOs’ modelling in this area;
  • Advising on procurement design models with investigation into competitive options that are auction-based, as well as identifying scenarios when a tariff-based approach may be required as an alternative;
  • Analysing the delivery timeline to define if and when an interim period is required and implementing any subsequent changes to the procurement methodology; and
  • Defining the criteria for eligibility and the necessary steps towards participant qualification.
