    Brief

    Programvareprodukter og lisenser

    TenneT TSO B.V. is planning the procurement of a Common IT platform and associated business capabilities to support the Coordinated Security Analysis (CSA) process, which will run load-flow calculations, contingency analysis, and coordinate remedial actions. The solution should be scalable, sustainable, and leverage open standards, modular architecture, documented interfaces, and technologies that minimize dependency on proprietary products. Suppliers are invited to participate in a preliminary market consultation to provide input on the development and implementation of this platform.

    About the bid

      The Transmission System Operators (TSOs) of the Central Europe Capacity Calculation Region are conducting a preliminary market consultation on development and implementation of a Common IT platform and associated business capabilities to support the Coordinated Security Analysis (CSA) process which runs load-flow calculations, contingency analysis and allows for the coordination of remedial actions among participating parties. The tool shall support this “Common CSA process” in the day-ahead (DA) and intraday (ID) timeframes; first go-live of the common CSA process in the region is targeted for 2029, preceded by a parallel run. The intent is to publish a European tender in Q1 2027 for the CSA Platform. This common CSA solution is the first implementation step towards the long-term process goal, which also includes an optimization of remedial actions, and cost sharing thereof. To support this evolution, the solution for common CSA process must be designed for scalability and long-term sustainability, leveraging open standards, modular architecture, documented interfaces, and technologies that minimize dependency on proprietary products, vendor-specific expertise, or closed ecosystems. The common CSA solution should allow to be extended with additional business capabilities and modules over time (e.g. Remedial Action Optimization module, Cost-Sharing process), to support the target processes (Regional Operational Security Coordination and Cost Sharing).

      Expertise for the Control Room of the Future program (Dynamic Purchasing System - EU-404)

      Welcome to the Dynamic Purchasing System (DPS) for Expertise for the Control Room of the Future program and adjacent subjects. Note:  This Dynamic Purchasing System is a continuation on the Mercell platform of the DPS that was previously operational on the Negometrix platform with Negometrix reference 159478 for which formal notice 2021/S 087-226573 was published on 5-May-2021 on the TED website. If your company was already qualified for participation on the Negometrix platform, a simplified procedure applies for re-establishing your qualification, see question 2.1 on the Mercell platform. TenneT will renew and innovate the (IT) systems that it uses for controlling and balancing its grids in the period 2021-2031. In connection with this, TenneT expects to be needing extensive external expertise, related to existing and new technologies and ways of working, in particular related to the challenges that TenneT faces in the energy transition. Compared to current ways of working, innovations will be needed to handle e.g. the increasing infeed of solar and wind energy that is far more difficult to predict and control than traditional generation. The subject of this tender procedure is a Dynamic Purchasing System (DPS) for expertise (including the development of algorithms and IT Tools) that TenneT needs in connection with the renewal of its (IT) systems related to the control and balancing of the electricity transmission grid. Initially, the DPS contains the following categories of expertise: 1. power system control and monitoring; 2. energy platforms and interconnected IT systems; 3. data analysis, artificial intelligence and machine learning; 4. system and process implementation. This Tender Dossier contains the rules for the Application by Economic operators for qualification under this DPS.  In order to become qualified for one or more of the categories, the Economic operator has to fulfil all the requirements of this DPS. In addition, the Economic operator needs to the answer all Mercell questions, and submit the requested documents and-or evidence at the respective Mercell question with the submission of its Application. During the course of time, the specific assignments (contracts) under the DPS will be tendered for which all suppliers that have qualified for the particular category will be invited to submit an offer. Any interested supplier may at any moment during the lifetime of the DPS submit a request to be qualified for participating in the tender procedures for specific assignments within one or more of the categories of this DPS. Your request will be accepted if it satisfies the applicable requirements and if you accept the stated conditions. Once you have qualified, you will automatically receive a notification when TenneT publishes a request for proposal for a specific subject within a category for which you have qualified. TenneT emphasises that it would also like to attract small and medium sized companies to this DPS. Qualification requests will be processed by TenneT in the sequence of receipt. TenneT will inform you as soon as possible and endeavors to do so within 10 working days from the date of receipt about the acceptance or rejection of your qualification request. During the lifetime of the DPS, TenneT will be entitled to add new categories, to close existing categories, and to split-up existing categories in to one or more categories.
