Previous publications This Tender Notices follows the UK3 Planned Procurement Notice published on 5 March 2025. Reference: 2025/S 000-007973 TI LirIC Limited is a wholly owned subsidiary of Transmission Investment (TI), a leading UK-based energy and utility investment platform. TI is part of TAQA Transmission, a subsidiary of the TAQA Group. The LirIC Project TI LirIC Limited is engaged in the development of an up to 700MW High Voltage Direct Current (HVDC) electricity interconnector project that will connect the Great Britain (GB) and Irish (I-SEM) transmission networks. This project is called the "LirIC" Project (https://tinv.com/intercon-projects/liric/). The project will link grid connection points in the GB and Northern Irish transmission grids. The LirIC interconnector shall utilise Voltage Source Converter (VSC) technology and the configuration shall be a Symmetrical Monopole. The rated DC voltage shall be +/-320 kV. The link shall be bi-directional and shall have a rated power (receiving end) of 700 MW The LirlC Project components The main components of the LirIC Project will comprise: •LOT B Group (to which this Tender Notice relates): • Two (2) High Voltage Direct Current (HVDC) electricity cables buried in or placed (and protected) upon the seabed between Northern Ireland (Kilroot) and Scotland (Hunterston) to a route length of approx.140km. •HVDC onshore and offshore cable 'transition bays' near the shorelines at the landfall points in both Scotland and Northern Ireland; It is expected that at both landfalls horizontal directional drilling (HDD) will be required to facilitate the export cables transition from onshore to offshore. •HVDC onshore cables from the transition bays to each of the converter stations assumed to be no more than 2km at each site; •High Voltage AC onshore cables from the Scottish converter station to the Scottish grid connection. The AC connection voltage on the GB side of the link is 400 kV and 275 kV at the NI side. (The High Voltage AC onshore cables from the NI converter station to the NI grid connection will be delivered by others.) •LOT A Group (under a separate Tender Notice in respect of the LirIC Project) •HVDC to HVAC VSC Converter Stations in both Scotland and Northern Ireland with associated civil and building works NOTE: The works and services for Lot A listed below are not being procured by means of this Tender Notice and bidders should refer to the separate publication) The Project has been awarded an 'in principle' cap and floor arrangement in Great Britain by Ofgem and a transmission licence in Northern Ireland.
