DS3 System Services – Volume Uncapped – Gate 4

Tender description

Gate 4 covers all 12 services as outlined in this qualification system briefing document. There is a separate DS3 system services agreement for services in Ireland, which is to be entered into with EirGrid and a separate DS3 system services agreement for services in Northern Ireland, which is to be entered into with SONI. The services are split into a number of lots for each of the TSOs as follows: Lots 1IE – 12IE relate to the system services required by EirGrid, Lots 1NI – 12NI relate to the system services required by SONI. It is intended that the start date of each of the contracts awarded under Gate 4 is 1 April 2021. It is intended that the term of each contract will last until 30 April 2023, but with an option for each TSO to extend the term of its contract in respect of any or all of its applicable lots in certain defined cases for 2 additional time periods of up to eighteen (18) months each, at the discretion of the contracting entity.

It is limited by the lowest availability in that 16 hour period. Lot 200985: FFR L12IE - Fast Frequency Response Fast Frequency Response (FFR) is the additional MW Output or MW reduction required compared to the pre- incident MW output or MW reduction, which is fully available from a providing unit within 2 seconds after the start of an event and sustainable up to 10 seconds after the start of the event. Lot 200986: POR L1NI - Primary Operating Reserve Primary Operating Reserve or ‘POR’ has the meaning given to it in the grid code. Lot 200987: SOR L2NI - Secondary Operating Reserve Secondary Operating Reserve or ‘SOR’ has the meaning given to it in the grid code. Lot 200988: TOR1 L3NI - Tertiary 1 Operating Reserve Tertiary 1 operating reserve or ‘TOR1’ has the meaning given to it in the grid code.
