2.1 Procedure

Title : Cable Monitoring System (DTS & DAS)
Description : TenneT is a leading electricity transmission system operator (TSO), headquartered in Arnhem, the Netherlands, and Bayreuth, Germany. TenneT manages over 24,500 kilometers of high-voltage and extra-high-voltage transmission lines, delivering reliable electricity to approximately 42 million end-users across the Netherlands and Germany. As the energy landscape evolves — with increasing demand and a growing share of renewables — TenneT is preparing its infrastructure for the future. The grid of tomorrow will depend not only on new connections, both onshore and offshore, but also on enhanced performance from existing systems under heavier loads. To meet these challenges, TenneT is launching a tender to implement advanced cable monitoring systems. These systems will offer critical insights into the performance and resilience of the grid’s lifelines — its cables — ensuring optimal operation as Europe transitions to a more sustainable energy future. The tender process is organized into three distinct lots, each focused on specific technologies: Lot 1: Distributed Temperature Sensing (DTS) – Brillouin Lot 2: Distributed Temperature Sensing (DTS) – Raman Lot 3: Distributed Acoustic Sensing (DAS) Each lot will result in a framework agreement for a duration of 2 (two) years, with 6 (six) options to extend with 1 (one) year. The tender starts with a pre-qualification phase during the period April/July-25, where interested parties must demonstrate their managerial, technical and procedural capabilities. The tender itself is scheduled for the period August/December-25. During the Tender Phase For the hardware-related lots, a test setup is being prepared. This setup will be used to evaluate range and accuracy requirements and. Tenderer needs to fulfil minimum requirement as set out in the tender documents. TenneT may value the outcome as part of the MEAT evaluation.
Procedure identifier : e0b7e937-f34b-4933-85fb-1edbe8d1b47b
Internal identifier : T135931
Type of procedure : Negotiated with prior publication of a call for competition / competitive with negotiation
Main features of the procedure : This procedure is split in three lots. For each of the three lots, the tender will follow a negotiated procedure with prior publication, ensuring transparency and competitiveness. The process begins with a selection phase, during which candidates demonstrate their eligibility and technical capabilities. Qualified candidates will then receive Invitation to Tender (ITT) documents specific to their selected lot(s), outlining detailed instructions for the next phase. This is followed by a structured round of clarifications, verifications, and negotiations, allowing TenneT and the candidates to align on expectations and refine proposals. Based on these discussions, TenneT will establish a set of final requirements—the "baseline"—which will be included in the Final ITT. These baseline requirements must be unconditionally accepted by the tenderers in their Best and Final Offer (BAFO). The final stage is the contract award, which will be determined using the Most Economically Advantageous Tender (MEAT) principle, focusing on the best price-quality ratio. This consistent and structured approach will be applied to each individual lot, ensuring fairness, clarity, and alignment with TenneT’s high standards.

5.1.10 Award criteria

Description of the method to be used if weighting cannot be expressed by criteria : The objective of this procedure is to award the framework agreements to the tenderers that offer the economically most advantageous tenders, with the best price-quality ratio. The best price-quality ratio will be determined by means of a price correction system. The tender price will form the basis of the evaluation, and the added value in terms of quality (expressed in a fictional discount % based on a scoring of the qualitative award criteria) forms a fictional correction to the tender price, resulting in a fictional tender price.
