Description

This Tender is performed by TenneT TSO B.V (TenneT). TenneT is a leading European electricity Transmission System Operator (TSO) with its main activities in the Netherlands and Germany. With over 23,000 kilometers of high-voltage connections we ensure a secure supply of electricity to 41 million end-users. TenneT employs approximately 4,500 people and has a turnover of EUR 4.1 billion. TenneT is one of Europe's major investors in national and cross-border grid connections on land and at sea, bringing together the Northwest European energy market and enabling the energy transition. TenneT takes every effort to meet the needs of society by being responsible, engaged and connected. Taking power further. TenneT is a key player in the electricity supply chain. This chain consists of producers of electricity from both conventional and renewable fast-growing energy sources, grid companies that transmit electricity (including TenneT), electricity suppliers, customers (industrial and small-scale users) and prosumers (energy consumers acting as producers). TenneT's high-voltage grid is connected to regional and local distribution grids managed by various other grind companies (so-called Distribution System Operators, DSO's) and directly to large industrial customers. More information about TenneT can be found at www.tennet.eu. As the project porfolio needed to realise the energy transition is ever growing, TenneT is looking to purchase a large amount of steel road plates to realise said projects. The marketconsultation held before this procedure has been sumarized and attached to this tender. This tender is a retender for the failed tender T143950. TenneT has amended requirements and scope resulting in a material change.

Who wins its contracts

Many suppliers

different companies won its awards: 22
of the awards went to the three most frequent winners: 24%

Based on 25 awards with a named winner over the last 3 years. Counted by award, not by value, because lot and framework amounts are not comparable. Concentrated means the three most frequent winners took 65% or more of the awards; many suppliers, under 35% with at least ten different winners.

Competition

of the awards went to companies based in another country: 13%

As the official award notices state them, over the last 3 years. Tenders per lot count open and restricted procedures only: in a negotiated procedure or a direct award a single tender is the procedure itself. The country is the one the notice gives for the winner.

One dot per award, on the day it was signed, sized by its value. A ring is an award with no published value.
