EU invests in priority energy infrastructure

05.02.2019

The “Connecting Europe Facility” (CEF) programme by the European Commission (EC) is a major European funding instrument to support the Energy Union, which is one of the EC’s policy priorities. CEF promotes the development of high performing, sustainable and efficiently interconnected trans-European networks in transport, energy and digital services sectors. Significant infrastructure projects of TSCNET shareholders are also considered as Projects of Common Interest (PCIs) and worthy of support.

PCIs financed by CEF include for example the Viking Link interconnector of the Danish transmission system operator (TSO) Energinet, the SuedLink DC line in Germany – a joint venture of the Dutch-German TSO TenneT and TransnetBW from southwestern Germany – and the joint smart grid project SINCRO.GRID of TSOs ELES and HOPS from Slovenia and Croatia respectively.

Last week, the EU Member States endorsed the EC’s proposal to invest a further €800 million under the CEF in infrastructure projects with high cross-border benefits. The current approval concerns the CEF’s financial support for studies and work on a total of 14 projects. Priority has been given to initiatives to increase competitiveness, improve security of energy supply and contribute to sustainable development and environmental protection.

Agreement on minimum capacity at Danish-German border

25.01.2019

In July 2017, the Danish Ministry of Energy, Utilities and Climate and the German Ministry for Economic Affairs and Energy adopted a joint declaration on the increase of cross-border electricity trade between Western Denmark and Germany. The competent transmission system operators (TSOs), the TSCNET shareholders Energinet from Denmark and TenneT, the Dutch-German TSO, subsequently agreed to implement a joint countertrading programme. Energinet and TenneT have been meeting the requirements of the joint declaration since July 2017 and have since ensured minimum available hourly capacities for both directions at the border.

In addition, TenneT has committed itself to the European Commission (EC) in 2018 to further expand the coordinated trade programme and to implement the corresponding EC decision in cooperation with Energinet from January 2019. In order to better comply with TenneT’s additional obligations from the commitment, the two TSOs have now signed an extended agreement supporting TenneT in doing so.

Successful test for the Combined Grid Solution

09.11.2018

The Combined Grid Solution is a joint offshore connection project by the two TSCNET shareholders 50Hertz, one of the four German Transmission System Operators (TSOs), and the Danish TSO Energinet. The binational interconnector in the Baltic Sea will integrate the electricity systems of Denmark and Germany by linking the German wind farm Baltic 2 to the Danish wind farm Kriegers Flak. The utilisation of grid connections from offshore wind farms to couple the transmission grids of two countries is nothing less than a world premiere.

The laying of the two submarine cables “150kV-line KFE-BaZ 155“ and “150kV-line KFE-BaZ 156“ was completed at the beginning of July and the two TSOs have now successfully conducted 24-hour testing of both cables. Around noon on 6 November and in the afternoon thereafter, the two cables were energised one after the other up to the disconnector on the offshore substation OSS KFE and now are ready to transport electricity. Sebastian Wagner, Sub-Project Manager Sea cables at 50Hertz, and Energinet’s Project Manager Daniel Johan Brøndum jointly declared: “Everyone in the team worked closely together and delivered to-the-point. We are very happy and celebrate this success together.”

XBID is running stable

07.09.2018

The successful launch of the European Cross-Border Intraday (XBID) solution and ten XBID related Local Implementation Projects (LIPs) in June 2018 has marked a significant step towards the creation of a single integrated continent-wide intraday market. The aim of the XBID initiative is increasing the overall efficiency of cross-border trading and intraday coupling, which both are key components of the future European internal energy market.

The XBID solution has been running now for over two and a half months without any major incidents, delivering continuous trading of electricity across Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Norway, The Netherlands, Portugal, Spain, and Sweden. Many other European countries are to follow in a second XBID-wave in 2019. Up to now, the number of trades in XBID has exceeded 2.5m. As a result of this satisfactory commissioning, the Steering Committee, in consultation with the Nominated Electricity Market Operators (NEMOs) and Transmission System Operators (TSOs) involved, decided to shut down the rollback systems.

Among the TSOs collaborating in XBID are the TSCNET shareholders 50Hertz, Amprion, APG, Energinet, TenneT, and TransnetBW, as well as TSCNET client Creos from Luxembourg. Together they have developed a common IT system including one shared order book, a capacity management module, and a shipping module. XBID makes it possible to bring together bids of market participants from different market areas within the region covered by the project, provided there is sufficient cross-border transmission capacity. It thus bundles the whole European intraday continuous market and complements the existing day ahead market.

Danish security of supply among the best

09.07.2018

An availability rate of electricity of 99.995% of the time in 2017 is quite impressive, and the Danish TSCNET shareholder Energinet is the transmission system operator (TSO) presenting this outstanding value in its “Security of electricity supply report 2018”. With this remarkable confirmation of last year’s result (99.996%), Denmark is again among the leading European countries. According to Energinet, the excellent security value is partly due to the high level of underground cabling in Denmark.

The key features of today’s energy landscape ‒ such as the integration of extensive and increasing wind and solar power capacities, more electricity interconnectors between different countries, or the harmonisation of markets and grid operation via EC regulations ‒ all affect the Danish supply security, which is no longer a national, but a regional issue. Energinet is aware of the new challenges and will adress these with operational and infrastructural measures, but also with the introduction of market reforms to increase the flexibility of both, generation and consumption.

Combined Grid Solution: submarine cable installed

06.07.2018

In early May, all of the three offshore platforms for the planned Danish wind farm Kriegers Flak in the Baltic Sea were successfully installed. One of them will not only collect wind power, but also function as linking point for the Combined Grid Solution, the first Danish-German offshore interconnector. The Combined Grid Solution is a joint venture of two TSCNET shareholders, 50Hertz, one of the four German Transmission System Operators (TSOs), and the Danish TSO Energinet.

Just two months later, 50Hertz announces that the next significant step for the project has been taken. The Combined Grid Solution will integrate the electricity systems of Denmark and Germany by linking the German wind farm Baltic 2 with 25 kilometres of submarine cables to Kriegers Flak. Now both cables of the interconnector have been laid out completely. The Baltic 2 platform was the starting point for the cable laying, and on 5 July, the Kriegers Flak platform was reached.

Elke Kwapis, project manager at 50Hertz, acknowledges the good cooperation with Energinet in this process and states: “These are great news. In the business everybody knows how complex the installation of submarine cables can become.” Especially in this case, it was even more challenging than usual, because the Baltic 2 platform was constantly in operation during the cable laying.

XBID successfully launched

15.06.2018

After several years of complex and intensive development and testing, the Cross-Border Intraday (XBID) solution and ten XBID related Local Implementation Projects (LIPs) were finally initiated on 12 June, with first deliveries on 13 June. In order to create a single integrated European intraday market, several Nominated Electricity Market Operators (NEMOs) and nearly twenty transmission system operators (TSOs) from all over Europe collaborate in the XBID initiative. Among the TSOs are the TSCNET shareholders 50Hertz, Amprion, APG, Energinet, TenneT, and TransnetBW, as well as TSCNET client Creos from Luxembourg.

With a common IT system consisting of one shared order book, a capacity management module, and a shipping module, XBID bundles the whole European intraday continuous market and complements the existing day ahead market. From now on, continuous trading of electricity is possible across the following countries: Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Norway, the Netherlands, Portugal, Spain, and Sweden. Most of the other European countries are to follow in a second XBID-wave in 2019.

The XBID solution for creating a single integrated European cross-border intraday electricity market was succesfully launched.

CGS onshore transformers on site

03.06.2018

The Bentwisch substation near the city of Rostock in Mecklenburg-West Pomerania is the future onshore converter station for the Combined Grid Solution, the first Danish-German offshore interconnector. The project is a joint venture of two TSCNET shareholders: 50Hertz, one of the four German Transmission System Operators (TSOs), and Energinet, the Danish TSO. The Combined Grid solution integrates the electricity markets of Denmark and Germany by linking the Danish Kriegers Flak wind farm with its German counterpart, Baltic 2. Now another significant step for the interconnector has been taken, as two transformers have been supplied to Bentwisch.

In combination with a double converter system, the large-scale equipment is essential for balancing the asynchronous transmission systems of Germany and Denmark. The transformers were transported from Rostock harbour to the substation per heavy-duty road transport. The second arrived in Bentwisch on the night of 29 to 30 May, and the first three weeks before. “We have thus reached another milestone on the way to commissioning the Combined Grid Solution. The transformers are the most important technical components for the back-to-back system on site,” comments Martin Henschel, specialist engineer at the 50Hertz Northern Regional Centre.

Cooperation for the green and digital transition

25.05.2018

The European energy landscape is changing constantly and fast, and there are two main factors that radically influence the conditions for the players in the energy market: the energy transition and the digital revolution. New digital developments offer great opportunities for companies from the energy sector to closer cooperate with companies outside the sector’s traditional value chain in order to realise a smart and efficient green and digital transition. Modesty and professional ambition should balance each other in this challenging field of work, or in the words of Thomas Egebo, CEO at TSCNET shareholder Energinet, the Danish transmission system operator (TSO): “We don’t have all the answers, but we would like to be part of the solution.”

On behalf of Energinet and the European Network of Transmission System Operators for Electricity (ENTSO-E), Thomas Egebo was the host of the Digital Round Table on 24 May in the Danish Capital of Copenhagen. High-level representatives from Microsoft, GE Power, Renault, Envision ‒ China’s second-largest wind turbine company ‒ and other international companies and organisations attended the event to discuss the impact of new technologies and digitalisation on the energy sector and the possibilities for new partnerships between companies from the traditional energy sector and other companies.

Many of the prospective solutions are still unknown to us today, but it is certain that data is essential for the energy future. Energinet wants to be a catalyst in this area to help market participants create products of the future. Thomas Egebo explained that a TSO such as Energinet can supply production data and information about the state of the network to businesses and consumption data to individual consumers. “Data is something that everyone can tap into, as well as a crucial element of the new business models, in which consumers can make a real difference in contributing to the integration of renewable energy,” commented Mr Egebo.
