Tender for the Tunnel Power Supply contract for the Fehmarnbelt Fixed Link

Description

The Fehmarnbelt Fixed Link Project is the final stage in the realisation of a straight traffic corridor between Scandinavia and continental Europe. It will be an immersed tunnel containing two dual carriageways and a twin-track railway traversing the 19 km distance across the Fehmarnbelt between Rødbyhavn on the island of Lolland in Denmark and Puttgarden on the island of Fehmarn in northern Germany (incl. approx. 6 km on the landside). Femern A/S requires design, procurement and building/installation, testing and commissioning and maintenance of a substation. This will be located near Rødbyhavn on Lolland. Energinet will design and construct the connection with the grid to provide the 132 kV primary system (including switchgear, housings and bus bars) under a separate contract. The Tunnel Power Supply (TPS) contract relates to the design, construction and maintenance of the substation and the ancillary works. This should be achieved while observing Femern A/S' CSR policies. Lot 1: The TPS Contractor will be required to design, manufacture and build/install the power substation (*design and build contract) to provide a) railway traction power (*traction power supply) and b) power supply to the Tunnel and its ancillary facilities. Further the TPS contractor is envisaged to provide maintenance (*maintenance) of the substation for a period of 5 years (coinciding with the defects notification period in the TPS contract). Femern A/S' programme requires the power supply to the Tunnel (road and ancillary facilities sub-system) to be operational and handed over first, with the traction power sub-system to be operational and handed over at a later stage. The timing of each stage is still being developed. The TPS Contract includes (without limitation): — 2 x 132/20 kV three phase transformers for the tunnel power supply (excluding switchgear for 20kV); — 132/25 kV single phase transformers for the railway traction power supply and voltage unbalance compensation or 132/25kV full convertor substation; — switchgear for the 25 kV power supply; — filter equipment (if necessary); — earthing of the entire substation(including the main earthing bar); — 400 V uninterruptible power supply; — lightning protection system — control systems (including for remote operation); — testing, safety and technical approvals; — such other works, supplies and/or services that are necessary to deliver the sub-systems; — buildings and fit out for the switchgear, control room and site employee facilities; and — related works such as foundations, oil spill troughs for transformers, drainage for the substation (including oil spill collectors, connections to local utilities and facilities), lighting and noise dampening. Femern A/S has contracted with a civil works contractor to prepare the site for the TPS contract. The prepared site will comprise of a prepared and elevated earthworks platform and sheet pile perimeter (and flood protection) wall with watertight gates. The TPS Contractor will be required to coordinate closely with other Project contractors and Energinet in relation to the design and execution of the works and the management of interfaces. The TPS Contract will cover such works, supplies and/or services that are ancillary to the works set out above. The TPS contractor is expected to carry out the works with full focus on health and safety (*safety) and in observation of principles set out in terms of ethical, social and environmental behaviour (e.g. UNGC global compact, labour related obligations) (*compliance with CSR requirements). Sections II.1.7); the amount was an estimate of the contract price for the entire term of the contract as stated in the Contract Notice (2021/S 074-189721).
