Future perspectives of underground cabling


The Renewables Grid Initiative (RGI) invites to an international workshop on “The prospects of undergrounding power lines”. The event will take place on 5 and 6 July in Raesfeld, in the northwestern part of the German federal state of North Rhine-Westphalia. This location has not been chosen randomly, since in Raesfeld the workshop participants have the great opportunity to explore an ongoing cable project conducted by TSC member Amprion, one of the four German transmission system operators (TSOs). Amprion serves also as host of the RGI event.

What is the status quo of underground cabling for power transmission in Europe? Firsthand-accounts from TSOs and stakeholders on pilot cable projects like the one in Raesfeld will provide the groundwork for the workshop discussions. Apart from the hosting TSO Amprion, several TSC members are also part of the RGI family: 50Hertz from Germany, the Croatian TSO HOPS, Swissgrid from Switzerland, and the Dutch-German TSO TenneT. Since its foundation in 2009, RGI supports the development of the transmission system infrastructure needed for integrating renewable energy.

Long term transmission rights in the Core CCR


The European Core capacity calculation region (CCR) consists of sixteen central European transmission system operators (TSOs). Ten TSC members are among the partner TSOs: APG (Austria), ČEPS (Czechia), ELES (Slovenia), HOPS (Croatia), MAVIR (Hungary), PSE (Poland), the Dutch-German TSO TenneT, and the three further TSOs from Germany 50Hertz, Amprion, and TransnetBW. They are supported by other Central European TSOs, such as SEPS from Slovakia.

The respective TSOs have mapped out a proposal for the regional design of long-term transmission rights in accordance with Article 31 of Commission Regulation (EU) 2016/1719. This includes the implementation of the first version of the Flow Based Intraday Capacity Calculation methodology in the Core CCR. Additionaly, the European Network of Transmission System Operators for Electricity (ENTSO-E) has opened a public consultation on the TSO proposal for stakeholders and concerned parties. The consultation will be open until 10 April.

HOPS enters Renewables Grid Initiative


Since its foundation in 2009, the Renewables Grid Initiative (RGI) is devoted to exploring the best options to develop the transmission system infrastructure needed to succesfully integrate large shares of renewable energy. RGI promotes investments in grid extension and tries to increase the much needed public and political support.

Transmission system operators (TSOs) and non-governmental organisations such as WWF International, BirdLife Europe, Germanwatch, Fundación Renovables, or the Climate Action Network are teaming up in RGI. Four TSC members – 50Hertz and Amprion from Germany, Swissgrid from Switzerland, and the Dutch-German TSO TenneT – are already part of RGI. Now the Croatian TSO HOPS has also officially joined RGI.

Core CCR expedites market integration


A total of sixteen central European transmission system operators (TSOs) cooperates in creating a European core capacity calculation region (CCR). This considerable high number of participants results in a Core CCR covering the largest part of central continental Europe. Among the associated TSOs are ten TSC members: APG (Austria), ČEPS (Czechia), ELES (Slovenia), HOPS (Croatia), MAVIR (Hungary), PSE (Poland), the Dutch-German TSO TenneT, and the three further TSOs from Germany, 50Hertz, Amprion, and TransnetBW.

CCRs are conceived as geographical areas in which coordinate cross-border capacity calculation, capacity allocation and congestion management is applied. With their CCR cooperation, the TSOs follow a decision by the European Agency for Cooperation of Energy Regulators (ACER) from November 2016 on merging regional coordinations to an enlarged European core region in order to promote the integration of Europe’s energy markets.

The fulfillment of CCR-related obligations in accordance to the respective European Commission Network Codes implies that the TSOs are committed to the developement of common methodologies for three principal tasks: day-ahead flow-based capacity calculation of cross-border transmission, capacity calculation for intraday and long-term time-frames, and the coordination of redispatching and countertrading to minimise congestions. Common methodologies in these fields will ease cross-border trade and optimise transmission capacities without endangering the security of supply.

SINCRO.GRID awarded as European key project


Within the frame of the “Connecting Europe Facility” programme, the EU invests €444m in key energy infrastructure. On 17 February 2017, the member states approved to the European Commission’s proposals on how to invest that large amount of money beneficially. Among the eighteen projects selected for funding is the smart grid project SINCRO.GRID destined to lead to a more efficient use of the electricity transmission grid in both Croatia and Slovenia. The EU supports SINCRO.GRID with €40m.

The two TSC members ELES, the Slovenian transmission system operator (TSO), and HOPS from Croatia participate in SINCRO.GRID. Two distribution system operators from Croatia and Slovenia respectively supplement the consortium. Since Croatia and Slovenia are central to the European electricity transmission system, the respective national TSOs host significant east-west electricity transit flows. The increase in renewables in the south-east European region will further enhance such transit. Both TSOs acknowledge their responsibility in ensuring supra-regional system security and therefore are taking actions to contribute to the European targets for a not only a secure, but also a sustainable and efficient future energy system.

SINCRO.GRID involves innovative systemic approaches in order to solve short term operational security issues affecting Slovenia, Croatia and whole south-east Europe. Synergy effects enable ELES and HOPS to manage the additional renewable energy with the current infrastructure. The result is a secure energy supply without the need of building new overhead lines.

Bridging the east-west-divide


The European Network of Transmission System Operators for Electricity (ENTSO-E) hosts its second of three regional conferences in 2016 on 23 September in Bratislava, the capital of Slovakia. The “Central East European Regional Conference” is devoted to the opportunities of an extended regional and supra-regional cooperation for the European electricity market from the perspective of Central Eastern Europe. The status, the progress and the perspectives of the power market integration between Central Eastern and Central Europe – 27 years after the end of the cold war – are the primary topics of the event.

Among ENTSO-E’s partners in the organisation of the event are the Slovakian Ministry of Economy, the Florence School of Regulation and several transmission system operators (TSOs) including eight TSC members: 50Hertz, one of the four German TSOs, the Austrian operator APG, the Czech TSO ČEPS, ELES from Slovenia, the Croatian TSO HOPS, the Hungarian Company MAVIR, PSE from Poland, and the Dutch-German TSO TenneT.

Numerous high-profile representatives from European and national politics, authorities, companies and associations contribute as speakers to the conference. Naturally, top executives from all the participating TSC members are to be found on the prestigious speaker’s list. Siem Bruijns, Managing Director of TSCNET Services, is also to make a contribution to the conference.

Reconnection decennial


On October the 10th, 2004 the power grids of South-Eastern Europe and the rest of Continental Europe were successfully reconnected. In remembrance of that milestone in the European grid history HOPS, the Croatian TSO and ENTSO-E, the European TSO network had organised the 10th anniversary celebration in Zagreb, Croatia with personalities from politics and the power industry. “An almost herculean task had to be performed ten years ago, and we would be well advised taking the reconnection and its begetters as an example,” said Rudolf Baumann, the Chairman of the TSC Steering Committee yesterday in his speech during the celebration.
