The TenneT TSO GmbH , based in Bayreuth is a German transmission system operator and a subsidiary of the Dutch electricity network operator TenneT . TenneT TSO operates a Germany in extra high voltage - power grid (220 kV and 380 kV) between Schleswig-Holstein and Bavaria with a total length of around 12,980 kilometers.
The company goes back to the 2009 spin-off of the transmission network division from E.ON Netz GmbH within the vertically integrated energy group E.ON and the subsequent disinvestment by E.ON. E.ON Netz, based in Bayreuth, was created in 2000 when Bayernwerk AG and PreussenElektra AG merged to form E.ON Energie AG . The distribution range remained after the split in the E.ON network.
In May 2008, the E.ON Group undertook as part of a since 2007 ongoing antitrust case its due to alleged abuse of - dominant position as a transmission system operator on the secondary balancing energy market and also because of legal requirements for unbundling (→ EnWG -Novelle 2005) - towards the European Commission to sell its German extra high voltage network division to a competitor. With the commitment in November 2008, E.ON had the antitrust proceedings stopped by the EU Competition Commissioner Neelie Kroes in the run-up to the EU's third energy package . According to the commitment, the part of the company should be sold by December 1, 2010 at the latest.
As a result, on May 4, 2009, transpower stromtransmission gmbh (TPS), based in Bayreuth, was entered in the commercial register, which had been spun off from E.ON Netz but still owned by E.ON. At that time, Transpower had around 650 employees.
Ownership unbundling and renaming
In November 2009 E.ON announced that it had agreed on a sale with the Dutch electricity network operator Tennet . The takeover of Transpower Stromtransfers GmbH by Tennet (specifically by TenneT GmbH & Co. KG , then still Transpower GmbH & Co. KG ) for around 1.1 billion euros was completed on February 25, 2010 with retroactive effect to December 31, 2009. At the beginning of 2010, Transpower employed around 725 people.
A few months later, with effect from October 5, 2010, Transpower was brought into line with the name of the parent company and has been called TenneT TSO GmbH since then . The abbreviation TSO on behalf means Transmission System Operators ( english transmission system operator ).
The sole shareholder of TenneT TSO GmbH has been the German TenneT GmbH & Co. KG since 2010 , which is owned by the Dutch TenneT Holding BV through several intermediate companies . For TenneT GmbH & Co. KG further investments and subsidiaries are in Germany, u. a. the TenneT Offshore GmbH . TenneT Holding is owned by the Kingdom of the Netherlands ; the Dutch Ministry of Finance holds the stake .

In 2006 E.ON Netz in Schleswig-Holstein started a field test for overhead line monitoring on the 110 kV line Niebüll - Flensburg and was able to increase the transmission capacity there by up to 50 percent depending on the weather. As of 2011, Tennet TSO had converted more than 900 km of extra-high voltage lines and 20 substations from Hamburg to Giessen to overhead line monitoring using 55 million euros in investments .
