Preparations for market inclusion of COBRAcable

15.03.2019

COBRAcable will be the first direct link between the electricity markets of Denmark and the Netherlands. It is a joint project of the two transmission system operators (TSOs) and TSCNET shareholders Energinet from Denmark and TenneT, the Dutch-German TSO. By increasing the exchange of surplus wind energy, the DC interconnector is to improve the cohesion of the European transmission system and the integration of the electricity market. COBRAcable also makes a sustainable contribution to the low-carbon energy future by providing the opportunity to hook up future North Sea offshore wind farms to the connection. The entire cable route comprises 329km, of which 307km are offshore and 22km onshore. Since two cables are laid in parallel, the total length of the cables is 658km.

COBRAcable reached the Dutch shore at the Eemshaven connection point in November 2018 and will be commissioned this year. Now the two TSOs are preparing the commercial operation of COBRAcable scheduled for the third quarter of 2019. The concrete measures are the inclusion of COBRAcable in the day ahead and intraday market coupling systems on 16 April 2019 and in the market coupling results on the following day, each with an allocated capacity of zero. The objective of this is to test the relevant IT systems and prepare for a successful launch of commercial operations later in the year.

TenneT presents Annual Report

21.02.2019

The transition to significantly more solar and wind energy in the power grid continues to have a substantial impact on the business operations of TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO). The apparent progress made by TenneT in this respect is reflected in the TSO’s just published Integrated Annual Report 2018, which is accompanied by the Green Finance Report 2018. To further advance the energy transition, TenneT focuses on the innovation and optimisation of the existing transmission system as well as on major national and international grid expansions. Manon van Beek, CEO at TenneT, refers to the necessity “to expand and reinforce our grids both onshore and offshore” and further explains: “We must also use the capacity of this infrastructure better, more flexibly and efficiently with the help of technology.”

TenneT again achieved a very good financial result in 2018. On an underlying revenue basis of €4.2bn, the TSO invested €2.3bn (2017: €1.8bn) in the energy transition and security of supply, with remarkable success, as grid availability in 2018 was 99.9988% within TenneT’s control area. And apart from the ensured reliability of the current transmission system, TenneT also wants to guarantee security of supply in the future. Since the energy future cannot be realised without inventive concepts, TenneT was and will be very active in innovation research for a flexible and affordable energy system based on solar and wind energy as well as green hydrogen. Several research projects are currently underway with renowned partners from industry and science.

Especially in terms of wind energy, TenneT is setting standards by reaching a new milestone in Germany and bringing almost 17TWh of offshore wind energy ashore in 2018. TenneT’s total connection capacity for offshore wind farms grew to 6,232MW. The BorWin3 and DolWin6 projects, which will be completed in 2019 and 2023 respectively, will further increase capacity to more than 8,000MW in Germany, while the development of an offshore grid in the Dutch North Sea is also progressing as planned.

Another important operational objective of TenneT is the further integration of the Northwest European electricity market, which is essential for the success of the European energy targets. One of TenneT’s current projects is the Doetinchem-Wesel link between the Netherlands and Germany, which went into operation in September 2018. In addition, the COBRAcable subsea connection between the Netherlands and Denmark has “landed” at the Eemshaven connection point and will be commissioned this year. Also worth noting is the NordLink cable connection currently under construction, which will be the first direct link between the German and Norwegian markets. The 624km interconnector is expected to come on stream in 2021. TenneT will then be operating 16 interconnectors in total.

TenneT reports on a prolific 2017

23.02.2018

With the Integrated Annual Report 2017 and the Green Finance Report 2017, TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO), yet again presents a combination of healthy financial results (22 percent boost in revenue, experiencing a jump from €3,227 million to €3,948 million) with an enduring commitment to the sustainable energy future and impressive investments (€736 million invested in the Netherlands, and €1,032 million in Germany) in the transmission system of the future. The company’s strategy for increasing the grid resilience while maintaining high supply security includes extension of the TSO’s onshore and offshore infrastructure, the development of a more flexible electricity system, and the introduction of intelligent software based on blockchain technology.

Prominent examples of TenneT’s forward-thinking actions in 2017 are two pilot projects in the Netherlands and Germany, which enable consumers to take part in the electricity market, as well as offshore systems for connecting wind farms to the onshore grid, or interconnectors such as the Dutch-Danish COBRACable and NordLink between Germany and Norway. The conception of an artificial island in the North Sea, the North Sea Wind Power Hub, to bundle wind power capacities and, moreover, to connect national markets, is perhaps TenneT’s most outstanding future vison in this regard. In 2017, TenneT was able to enlarge the Power Hub Consortium promisingly.

TenneT’s CEO Mel Kroon is profoundly pleased with the TSO’s business year and comments: “In 2017 we made good progress on realising our strategic priorities.” Mr. Kroon emphasises that the company succeeded in combining supply security with grid modernisation and expansion, but also pointed out the future tasks: “Now that modern society is increasingly dependent on electricity, the costs of renewable electricity decrease significantly and ‘green power’ is supplied by a wide range of sources at countless locations, we must shift to a new electricity system that can support this revolution.”

Collaboration and innovation – TenneT report

28.07.2017

A whole lot of aspects from the half-year report of TSC member Tennet are worth mentioning, but what might be considered as especially valuable and forward-thinking is the continuing effort of the Dutch-German transmission system operator (TSO) in promoting the European energy collaboration and market integration. Tennet complements these efforts with the development of digital solutions for the renewable’s integration to facilitate the energy transition.

Mel Kroon, CEO at TenneT, mentions two essential catalysts of a sustainable European energy future: “Further integration of the North-West European electricity markets” to improve green energy management, as well as “smart, innovative systems” to match future energy demand and supply. Among TenneT’s most prominent international projects are the so called Power Link Island, a North Sea Wind Power Hub to be developed jointly with Danish TSO Energinet, the COBRAcable between the Netherlands and Denmark, or the NordLink cable to connect the Norwegian and German electricity markets. TenneT’s key initiative in terms of smart software solutions is the research on block chain technology fostering local, flexible electricity generation.

The company’s European commitment is emphasised by the opening of a representative office in Brussels in June and the appointment of Ben Voorhorst, Chief Operating Officer of TenneT, as President of the European Network of Transmission System Operators for Electricity (ENTSO-E) in March. As far as TenneT’s operating results in the first half of 2017 are concerned, the TSO reports satisfactory figures, with profits before interests and taxes growing to €478m. Infrastructural investments in the Netherlands and Germany remained on a high level since large-scale grid extension projects, on- and offshore, are being implemented continuously. To help financing these investments in the transmission of the renewables, TenneT has yet again succesfully issued long term green bonds with a nominal total value of €2bn in March and June respectively.

Data transmission to accompany COBRA

23.09.2016

The two TSC members Energinet.dk, the Danish transmission system operator (TSO), and TenneT, the Dutch-German TSO, are intending to equip the submarine COBRAcable connection with an additional fibre-optic data cable. The data cable’s primary function is to exchange technical information and to facilitate communication between the two appendant converter stations in Eemshaven in the Netherlands and Endrup in Denmark.

The COBRAcable, scheduled for operation in 2019, will be a new submarine DC interconnector with a total length of 325km and a capacity of 700MW. As direct link between the Dutch and Danish power grids, it will make the two national energy capacities structurally available to the other partner country. COBRAcable will promote the interexchange of renewable energy and ensure supply security in Denmark and the Netherlands, respectively.
