This procurement falls under the goods category and is classified as power converters (CPV Code: 31121110). The contract, awarded through a limited procurement method without prior publication, was signed on 17 December 2021. This specific project follows a fire incident in September 2021, which led to significant operational disruptions at the Sellindge converter station in the UK, necessitating the urgent replacement of damaged equipment to restore full capacity. This tender presents a beneficial opportunity for businesses specialising in high-voltage direct current (HVDC) equipment and services. Firms with capabilities in manufacturing and delivering technical solutions tailored for energy interconnectors, especially those who can engage in sole-sourced contracts, will find this particularly advantageous. Given the unique technical challenges identified during the evaluation phase, businesses that have strong relationships with OEMs or possess expertise in HVDC systems integration are likely to excel in this sector. ## Notice Design, manufacture, delivery and commission of HVDC equipment for IFA - Sellindge. ### Lot Information Lot 1 Design, manufacture, delivery and commission of HVDC equipment for IFA - Sellindge. ### Procurement Information In September 2021, a fire broke out at Sellindge, the UK converter station of the IFA1 interconnector. Due to the damage to assets onsite the IFA capacity was reduced to zero (from 2000MW). In late October 2021 bipole two was returned to service, restoring the site to half capacity (1000MW). Due to the damage sustained on bipole one, an asset replacement or repair exercise was required to be undertaken in order to recover the second 1000MW of IFA capacity. Multiple options were explored to return full capacity of the interconnector, including refurbishment of the damaged equipment. Independent HVDC experts were engaged to support an assessment of the feasibility of integrating third party (non-OEM) assets with the original OEM system and to review the technical challenges associated with interfacing replacement equipment with the current control system, not damaged in the fire, which is in use on both the UK and French side of the interconnector. The independent assessment confirmed it was not technically possible to integrate third party (non-OEM) assets to the existing control system. Replacement of the control system, to attempt to facilitate third party replacement assets, was estimated to be uneconomical and would also require the agreement of RTE, the joint operator of IFA, due to the additional works required in both France and the UK. Such additional work would also lead to a significant extension of the recovery programme, leading to a further extension of the unavailability of a strategically significant transmission asset. Following the above evaluation, it was determined that competition was absent as the only viable technical solution was to replace the damaged assets on a like for like basis and therefore the decision was taken to proceed to contract with the Original Equipment Manufacturer to supply replacement assets on a sole source basis. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/001930-2022 | | Notice type | Award Notice | | Procurement type | Standard | | Procurement category | Goods | | Procurement method | Limited | | Procurement method details | Award procedure without prior publication of a call for competition | | Tender suitability | Not specified | | Awardee scale | Not specified | | All stages | Award | ## Dates | Field | Value | | --- | --- | | Publication date | 21 Jan 2022 | | Submission deadline | Not specified | | Future notice date | Not specified | | Award date | 17 Dec 2021 | | Contract period | Not specified | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | Not specified | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Complete | | Lots status | Cancelled | | Awards status | Active | | Contracts status | Active | ## Buyer | Field | Value | | --- | --- | | Main buyer | NATIONAL GRID INTERCONNECTORS LIMITED | | Locality | LONDON | | Post town | Central London | | Postcode | WC2N 5EH | | Country | England | | ITL 1 | TLI London | | ITL 2 | TLI3 Inner London - West | | ITL 3 | TLI35 Westminster and City of London | | Local authority | Westminster | | Electoral ward | St James's | | Westminster constituency | Cities of London and Westminster | | Delivery location | Not specified | ## CPV Codes ### Divisions - 31 - Electrical machinery, apparatus, equipment and consumables; lighting ### Codes - 31121110 - Power converters ## Release History - 21 Jan 2022 at 18:35 - Award - Award Notice - https://www.find-tender.service.gov.uk/Notice/001930-2022 ## Notice URLs - http://www.nationalgrid.com ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
