EirGrid and SONI have today published a consultation paper on the DS3 System Services Regulated Tariff Calculation Methodology alongside an accompanying report by Pöyry. 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 generation such as intermittent wind penetration (up to 75% instantaneous penetration).
One of the central work streams included in the DS3 System Services project plan is WS1 – Regulated Tariffs. The objective of this work stream is to develop and implement a methodology for determining the base tariff level for each DS3 System Service. In this consultation paper, we are focusing on the proposed methodology for determining the Regulated Tariffs for each DS3 System Service under the Enduring Arrangements. The purpose of this document is to provide stakeholders with information about our proposals and a guide to the consultation process. Respondents are asked to read the accompanying Pöyry report in advance of developing their responses or views to the questions posed in this consultation paper.
