Prolific exchange of cabling practices


From 5 to 6 July, the Renewables Grid Initiative (RGI) held an international workshop on “The prospects of undergrounding power lines” in Raesfeld, in the northwestern part of the German federal state of North Rhine-Westphalia. The event was co-hosted by TSC member Amprion, one of the four German transmission system operators (TSOs). Amprion conducts a pilot project on underground cabling in Raesfeld. Therefore the participants had the valuable opportunity to visit not only Amprion’s exhibition about underground cables during the course of the workshop, but also the construction site of the on-going project, where they inspected the laid cable and the cable transfer station.

The technology used in Raesfeld, the exemplary and early involvement of the affected public, and Amprion’s consideration of environmentally friendly aspects were introduced during the workshop. International experts additionally presented several other European underground cable projects, among those the Project Randstad North-ring by further TSC member TenneT, the Dutch-German TSO. The participants exchanged their technical knowledge and also how to translate it into understandable messages for policy makers and regulators. Antonella Battaglini, RGI’s Managing Director, expressed her opinion on the importance of professional exchange in order to “provide guidance for the handling of underground cables throughout the entire planning process.”

All in all, it became clear that AC cabling is still a new technology and TSOs have to gain experience in construction, technology, and operation through pilot projects. Gerald Kaendler, Head of Asset Management at Amprion, commented: “The exchange with the experts from across Europe has shown that the implementation of pilot cable projects is a good way to achieve the best use of cables in terms of acceptance and environmental impact.”

MARI workshop in Brussels


The European cross-border balancing project MARI (Manually Activated Reserves Initiative) was established in this year’s April. The project’s aim is to implement a European platform for balancing energy from Frequency Restoration Reserves with manual activation (mFRR) in accordance with the EU Commission Guideline on Electricity Balancing. Eight TSC members are among the total of 19 transmission system operators (TSOs) being associated in MARI: APG (Austria), ČEPS (Czechia), (Denmark), Swissgrid (Switzerland), the Dutch-German TSO TenneT, and the three further TSOs from Germany, 50Hertz, Amprion, and TransnetBW.

Already at a very early stage of the project, all MARI partners consider stakeholder communication and feedback to be highly important in order to develop a liquid and user-friendly platform. Therefore the MARI parties invite interested stakeholders to a project workshop on 4 September 2017 in the premises of the European Network of Transmission System Operators for Electricity (ENTSO-E) in Brussels, Belgium. Since the number of participants is limited, the event will also be broadcasted via webcast for registered users.

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.

Grid aesthetics in Milan


Today, the two-day workshop and field trip “Grid Aesthetics – How to engage stakeholders in landscape planning, design and aesthetics of grid infrastructure” started in Milan, Italy. The event with presentations, debate, and a simulation game is organised by the Renewables Grid Initiative in cooperation with the two EU-funded projects INSPIRE-Grid and BESTGRID. The Renewables Grid Initiative is supported by three of the TSC member TSOs (50Hertz, Swissgrid, and TenneT).

NRA Workshop in Munich


Today the common workshop among European Transmission System Operators (TSOs) and National Regulatory Authorities (NRAs) took place in Munich, Germany. The main topics were Multilateral Remedial Actions (MRAs) and its cost sharing, exchanging information on critical grid situations and potential countermeasures to ensure system security.

In the course of the workshop, TSC TSOs presented a proposal for a new cost-sharing method in the case of MRAs. The new method was received favourably by NRA representatives. In view of the topic’s complexity, they were emphatic about the progress made by the TSOs. The workshop was also taken as an opportunity to introduce the newly established TSCNET Services GmbH and its services for TSOs’ control centres.
