Conference and exhibition in Switzerland


On 18 June, the Energy Science Center of ETH Zürich, the international university for technology and the natural sciences in Zurich, Switzerland, will host a semi-diurnal conference in German language on the “Power Grid of the Future” (“Das Stromnetz der Zukunft”) including a panel discussion. Registration is obligatory (by 8 June). The conference is attended with the GRID EXPO (16-19 June), an exhibition informing on current grid projects. Both the conference and the exhibition are supported by the Renewables Grid Initiative (RGI) and the Swiss transmission system operator (TSO) Swissgrid. Swissgrid is a member of TSC.

G7 ministers visit converter platform


This Monday and Tuesday, the energy ministers and their representatives of Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States met in Hamburg, Germany, to discuss possibilities to ensure long-term sustainable energy security. One of the items on the agenda was the visit of HelWin alpha converter platform in the North Sea, operated by the Dutch-German transmission system operator (TSO) TenneT.

World’s largest offshore grid connection


The Dutch-German transmission system operator (TSO) TenneT took SylWin1 into operation. SylWin1 is the world’s most powerful grid connection with a capacity of 864MW. The now-operational link around 70km west of the island of Sylt in the German North Sea connects three offshore wind facilities (“Butendiek”, “DanTysk” and “Sandbank”) with a generation capacity of 288MW each.

French-Spanish HVDC link


Last week, the German electrical engineering and electronics company Siemens put the converter stations of the high voltage direct current (HVDC) link between France and Spain into operation.The project is led by Interconnexion Electrique France Espagne (Inelfe), a project joint venture between the transmission system operators (TSOs) Réseau de Transport d’Electricité (RTE), France, and Red Eléctrica de Espana (REE), Spain.

The new 320kv link between Baixas west of Perpignan, France, and Santa Llogaia, southwest of Figueras, Spain, can transmit a rated power of 2,000 megawatts in both directions and will double the energy exchange capacity between the two countries.

Strengthen Danish-German connection


The transmission system operators (TSOs) TenneT and 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


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.

DC connection to Norway


The final investment decision for NordLink, the first high-capacity power cable between Norway and Germany with a capacity of 1,400 megawatts, was taken today by TenneT, the Dutch-German TSO, and its two partners, the Norwegian TSO Statnett and KfW bank. The construction of the HVDC link with 516 km subsea cable is expected to start soon.
