## Summary

The NATIONAL GRID INTERCONNECTOR HOLDINGS LIMITED is currently conducting a tender titled "Simulation Studies for HVDC Systems," which falls under the engineering design services category in the UK and Belgium. This tender is part of an active procurement process, classified as a selective procedure with negotiations, and is set to conclude on 23rd February 2022. The successful contractor will engage in various simulation studies related to HVDC systems, covering aspects such as operation, control, protection concepts, and environmental studies throughout different project stages.

This tender presents significant opportunities for businesses specialising in engineering design and simulation services, particularly those with expertise in high voltage direct current (HVDC) systems. Companies that can deliver comprehensive studies, including offshore AC network assessments and basic design studies, would be well-suited to compete. The framework agreement may also permit a potential extension of contracts, which could further benefit businesses aiming to establish long-term partnerships with the buyers involved.

## Notice

Elia and NG are looking for a Contractor to get the necessary support throughout different HVDC Projects stages by performing simulation studies for HVDC systems. Expectations (scope of work) * concepts for operation, control and protection are reviewed and possibly further are developed * Offshore AC Network Studies (e.g. : Static power flow calculations, short circuit calculations, resonance interaction studies, Harmonic impedance loci calculations...) * Basic Design Studies (e.g. : Static power flow calculations, DC harmonic performance studies, etc.) * Environmental studies (e.g. : Electromagnetic & Ohmic couplings with adjacent infrastructures, etc.)

### Lot Information

Lot 1

The primary objective of this Framework Agreement is to get the necessary support for HVDC studies for NGIH and Elia for a common Project (the Nautilus project). These studies might be procured either jointly or separately by Elia and NGIH. However, this Framework Agreement could also be used solely by Elia for other HVDC projects (not joint projects with NGIH) like for example the MOG II Project. Additional information: This Contract Notice replicates the one published within TED under the title Simulation Studies for HVDC Systems and can be found under the Main CPV code 71320000 (Engineering design services). Elia will be leading the Tender Process with close support of NGIH. It is therefore preferred to send any requests to participate to Elias Aragones-Melhem (E-mail: elias.aragonesmelhem@externel.be )

Options: A potential extension of the contract is considered of twice two years and once 1 year ( + 2 + 2 + 1). If other options would be applicable, they will be described in the Tender Documents
