Strengthen Danish-German connection

08.04.2015

The transmission system operators (TSOs) TenneT and Energinet.dk want to boost the interconnection across the Danish-German border to around 2,500 MW. The two TSC member TSOs plan to upgrade the 220 kV connection between Dollern near Hamburg and Kassø in southern Denmark to 400 kV level by 2020. The 150 km transmission line is listed as one of the EU’s Projects of Common Interest (PCI).

Windy weather brings trouble

31.03.2015

Germany produces more and more wind power with more than 21,600 wind turbines. In 2014, the country doubled its offshore wind energy and installed on- and offshore wind turbines with a total output of 4.8 GW. A massive weather front on Monday and today leads to daytime peaks of up to 25 or 30 GW of wind power being fed into the grid and takes a heavy toll on the extra-high voltage grids. The stormy weather boosts power output, and means a lot of work for the operators both at the control centres of transmission system operators (TSOs) and TSCNET Services to avoid congestions. Besides, such large influxes of renewable power make the case for expanding the power network.

Lights switched back

27.03.2015

This morning around 9:45 am, large areas of the Netherlands including the capital Amsterdam had been hit by a power outage. The electricity failure was caused by a power grid overload due to a defect at a substation in Diemen outside Amsterdam. All flights from and to Schiphol, Europe’s fourth largest airport, had to be canceled briefly. One the whole, approximately one million households were affected.

According to TSC member TenneT, the Dutch transmission system operator (TSO), power had been restored to most parts of the densely populated region by noon. The failure itself lasted about an hour. TenneT’s experts are investigating why the back-up system which should have kicked in did not function properly.

More efficiency in Switzerland

24.03.2015

The Swiss transmission system operator (TSO) and TSC member Swissgrid welcomes the results of the consultation process for the national grid strategy, which ended last week. The strategy is supposed to establish an appropriate process for the broadly coordinated grid planning and to allow a more efficient organisation of the approval procedures.

Repair work in Hungary getting on well

23.03.2015

In December 2014, two transmission lines were damaged in Hungary due to extreme weather conditions. Now the restoration process reaches its final phase, announced MAVIR Hungarian Independent Transmission Operator Company in a press release today. The Ócsa–Zugló 220 kV and the Albertirsa–Göd 400 kV transmission are expected to return to operation by June or July 2015.

Successfully passed the stress test

20.03.2015

Today’s partial solar eclipse over continental Europe led to a major challenge for the power grid. The most critical moment was between 10.45 am and 11.15 am when the solar generation started to go up again. The transmission system operators (TSOs) managed successfully to keep the electric grid operating in balance. As a result of the sunny weather, the German TSOs (TSC members 50Hertz, Amprion, TenneT, and TransnetBW) had to manage high and fast variations of 39 GW of installed solar generation. Everything went well.

“The solar eclipse is an example for the success of European and regional cooperation organised by ENTSO-E,“ says Konstantin Staschus, Secretary-General of the European Network of Transmission System Operators for Electricity (ENTSO-E).

Prepared for the solar challenge

20.03.2015

Today’s partial solar eclipse between 8.40 am and 12.50 pm presents a significant challenge for the European transmission system operators (TSOs) and TSCNET providing 24/7 services for them. The change in solar radiation will influence the output of photovoltaics greatly and for the first time this is expected to have a relevant impact on our power system. In close cooperation with the European Network of Transmission System Operators (ENTSO-E), the continental European TSOs have well prepared and have planned a series of countermeasures to balance the power and to avoid blackouts or overloads.

We at TSCNET have bolstered our teams and all relevant internal processes to support TSOs’ operational planning processes and coordination optimally. Operational coordination among Europe’s TSOs will be crucial. During the eclipse, the control rooms will be continuously connected via teleconferences. We are very confident that the European power grid can cope the eclipse and will pass this stress test.

TSCNET at “APG grid circle”

17.03.2015

Today, Austrian born Marlene Petz and Philipp Kmeth from TSCNET Services were guests of the transmission system operator (TSO) APG at the occasional information exchange forum “APG grid circle” in Vienna, Austria. Both of them came from APG when they started to work at TSCNET, the TSC TSOs – Joint Office at that time, in the mid of 2013. They did not only introduce the TSO Security Cooperation (TSC) and TSCNET Services, but also provided insight into their daily work, including working principles, the consistent working group structure, and the complex TSC processes moderated by the operators.

The presentation was followed by an animated discussion with the audience about the advantages for APG as a member of TSC and one of TSCNET’s shareholders. Among the issues raised were the challenges APG faces as a centrally located TSO in the european transmission grid and that have to be met in close coordination between all the neighbouring TSOs involved. The conversation also covered APG’s role as one of the catalysers in the TSC community for developing services and processes.

TV report about Solar Eclipse

13.03.2015

The “Abendschau”, a magazine-programme on Bavarian TV on weekdays, reported about transmission system operators (TSOs) preparing for the March 20 solar eclipse. The tv crew had visited TenneT Germany and TSCNET Services. One of the interviewed experts was Alexander Wirth, one of the two Managing Directors of TSCNET Services GmbH, talking about this unprecedented challenge for the European electricity system.
