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 and Gasunie present “Infrastructure Outlook 2050”

15.02.2019

Electricity grids in Europe are increasingly confronted with the fluctuating feed-in of renewable energies. Consequently, they need more flexibility, which can be provided by the comprehensive coupling of sectors such as energy, transport, industry and heat. Many European transmission system operators (TSOs) have identified the integration of electricity and gas transmission infrastructures as a promising approach to fulfilling the requirements of the coming sustainable energy system. Electricity and gases must complement each other, since interlinking both grid types creates new storage possibilities and also provides additional transport options for renewables. Both factors will help to keep energy supplies reliable and affordable also in the low carbon energy future.

TSCNET shareholder TenneT, the Dutch-German TSO for electricity, and Gasunie, the Dutch TSO for gas, each operate grids in the Netherlands as well as in Germany. Last year they entered into a sector coupling partnership with plans for the Power-to-Gas (PtG) pilot plant “ELEMENT ONE”. Now the TSOs have presented their joint “Infrastructure Outlook 2050”. It clearly illustrates that the existing electricity and gas infrastructures in the Netherlands and Germany continue to play a decisive role in coping with the increase in renewable energies and achieving the Paris climate targets. The main conclusion of the joint TSO study is that electricity and gas networks must be more closely interconnected by 2050 in order to meet the objectives. The Outlook is also the first document of its kind to consider various scenarios for the future development of energy supply.

The importance of hydrogen from PtG technologies for energy storage and transport is also highlighted. But even despite the potential of sector integration, further expansion of the electricity grid remains essential, as all scenarios envisage a significant increase in the necessity of electricity transport. In addition, however, there must also be backing from political decision-makers and the creation of a clear, supportive regulatory framework. Manon van Beek, CEO at TenneT, argues that “energy systems are not converted overnight but require sustained, joint efforts”. She therefore sees the need for close cooperation between all those involved in the energy market. In this respect, the “Infrastructure Outlook 2050” represents a “solid, joint start with fresh insights”.

TSO-DSO platform for congestion management

30.01.2019

Grid operators in the Netherlands and throughout Europe are working intensively on expanding grid capacity, which is urgently needed in the wake of energy transition and economic growth. However, this cannot be achieved in the short term, but the use of flexible electricity from the market can help to avoid anticipated grid congestions. GOPACS (“Grid Operators Platform for Congestion Solutions”) is the name of a new technological tool developed in the Netherlands for this purpose. It is the result of a unique, active collaboration between four Dutch distribution system operators (DSOs) and TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO).

GOPACS is not a market platform in its own right but uses orders on existing market platforms. And this is how it works: If congestion is foreseeable at some part of the grid, operators would like to see, for example, a reduction in production or an increase in consumption. Via GOPACS, an invitation to tender is sent to market participants concerned, who place an appropriate purchase order on a connected market platform. To avoid negative impacts on the balance of the national grid, the reduction of generation in the congestion area is combined with a contrary order from a market party outside this area. The price difference between the two orders is covered by the operators, the two orders are matched, and congestion is resolved.

The Dutch grid operators are currently looking for market players who want to participate and use their flexibility productively. Participation in GOPACS is interesting for any market party with the possibility to influence electricity consumption or generation and to provide this flexibility for trading.

Together with Dutch DSOs, TenneT has launched GOPACS, a smart platform for market players to solve grid congestions

TenneT performs blockchain pilots successfully

29.01.2019

The energy transition demands digital transition – the number of renewable sources is increasing, while in the future there will be less and less conventional plants available to ensure the required flexibility and stability in the grid for which the transmission system operators (TSOs) are responsible. As such, the Dutch-German TSCNET shareholder TenneT is constantly seeking new decentralised sources that can replace lost flexibility. In addition to wind and solar energy, these can include batteries, industrial plants or cogeneration. This is where digitisation comes in, because only through so-called “aggregator” and block chain technology the capacity and potential of all these sources can be combined and fully utilised.

TenneT has launched two pilot projects last year, one in the Netherlands and one in Germany, both employing blockchain technology. In the first case, e-vehicles and in the second case household batteries were used to balance the grid and avoid congestions. The blockchain application is an IBM development and the Dutch green electricity supplier Vandebron is the cooperation partner in the Netherlands. Vandebron provides battery capacity from e-car charging sessions at TenneT’s request. In this way, the TSO can draw on an additional electricity pool. In Germany, TenneT collaborates with Sonnen E-services, a company specialising in home energy storage systems. Decentralised household batteries from Sonnen are integrated into the TenneT network via a blockchain and interconnected. Through the smart use of these batteries, Sonnen contributes to facilitating power transmission in Germany.

Since both blockchain tests were successful, TenneT and IBM have signed a contract for the further development of blockchain technology. The companies will intensify the implementation so that many more parties can gain access to the electricity market. Three new partners have already been won as additional “aggregators” to ensure improved matching of electricity supply and demand. TenneT CEO Manon van Beek explains that the TSO offers not only “a new way of integrating decentralised sources”, but also “private individuals a good opportunity to participate actively in the energy transition, making the energy transition more affordable together”.

Lex Hartman resigns and TenneT adjusts management structures

02.01.2019

On 1 January 2019, personnel and structural changes at management level took effect at TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO). To begin with, Managing Director Lex Hartman resigns from the Executive Boards of TenneT TSO GmbH and TenneT TSO B.V. In addition, the company’s governance structure, related to the ongoing process of refining TenneT’s development strategy, will be adapted to better achieve the TSO’s future objectives.

TenneT CEO Manon van Beek wholeheartedly thanks Lex Hartman for his “major contributions in the Executive Board to the development of TenneT” and especially emphasised his significant role for “the improvement of TenneT’s visibility and reputation in Germany”. Lex Hartman, who began his career with TenneT in 1999 and held various positions during his long term of office, has been a member of the Executive Board of TenneT Holding BV since 2008 and of TenneT TSO GmbH since 2010. Mr. Hartmann indicates the need for a personal change after more than 10 years “as a board member for this fantastic company” and further comments: “I am grateful that TenneT gave me the opportunity to make a meaningful contribution to society.” However, Hartman will continue to serve the Executive Board as a strategic advisor.

As far as the new board structure is concerned, the Executive Board of TenneT Holding BV now consists of four directors: Manon van Beek (CEO), Otto Jager (CFO) and two COOs, Ben Voorhorst and Wilfried Breuer. The nomination of Wilfried Breuer is only temporary, as he has decided to accept a position as Technical Director at a manufacturer of power engineering technology. TenneT thanks Mr Breuer for his substantial contributions and commitment. In the first quarter of 2019, he will continue to work with the TSO, while the search for his successor has already begun.

Dutch recovery facility ready for operation

04.10.2018

Although it is most unlikely that there will ever be a complete power outage in the Netherlands, TSCNET shareholder TenneT, the German-Dutch transmission system operator (TSO), wants to be prepared even for such an unimaginable scenario and thus also fulfil European agreements. For these reasons, a new recovery facility for the high-voltage grid was put into operation at the gas-fired Enecogen power plant in the Rotterdam-Europoort area.

In the event of a total blackout, the Dutch power plants will have to be reactivated, which is exactly the task of the new equipment. Like an enormous starter motor, the system ‒ consisting of an emergency generator and a gas turbine ‒ switches the Rotterdam power station back on. Then the rest of the power supply, be it other large-scale plants, solar or wind farms, is connected back to the grid step by step in order to quickly reactivate the national transmission system.

The Enecogen recovery facility is the third emergency system contracted by TenneT in the Netherlands. With comparable units in the north and centre of the country, the new “starter of the south” now completes the TSO’s emergency and recovery concept for total power failures.

Dutch research on decentral balance maintenance

05.09.2018

The continuous maintenance of the balance in the electrical transmission grid between customer demand and supply is one of the core tasks of any transmission system operator (TSO). In order to further improve performance in this respect and to make balance maintenance more decentralised, TSCNET shareholder TenneT wants to explore possibilities to offer local electricity generation and regulating capacities. Decentral maintenance methods appear to be an appropriate response to an increasingly volatile and decentral energy generation. For this reason, the Dutch-German TSO has launched a pilot research project on the enhanced and decentral use of automatic Frequency Restoration Reserves (aFRR) within the Dutch transmission system.

TenneT is cooperating with seven partners from the energy sector on this project, which is a follow-up to a previous collaboration with the Dutch green energy supplier Vandebron on the employment of e-car batteries for grid control measures. With six additional partners, the field of investigation is now being expanded to also include wind and solar energy, combined heat and power generation, heating grids, electric boilers as well as electric pumps. This provides the research with the broadest possible spectrum of technologies and the widest scope of possible applications.

The pilot project derives its significance from the fact that currently the use of alternative energies in the aFRR market is not always possible due to inadequate specifications and technologies. TenneT aims to explore and, as far as possible, remove the technical hurdles in order to facilitate the use of regulating capacities from decentralised and sustainable sources.

First Borssele jacket ready for shipping

31.07.2018

A height of 55m, a length of 50m, a width of 28m, and a total weight of about 2730t ‒ these are the stately specifications of the jacket for the first transformer platform in the Borssele offshore wind farm zone. The connection of this area in the Dutch part of the North Sea to the onshore grid is the first large-scale connection project of TSCNET shareholder TenneT, which is being implemented under the Dutch National Energy Agreement for offshore wind farms. With the completion of the first platform substructure in a shipyard in Schiedam in greater Rotterdam, the Dutch-German transmission system operator (TSO) has reached the first milestone in the realisation of the Borssele connection project.

During the so-called load out, a time-consuming precision procedure, the jacket was lifted onto a seagoing barge. On Sunday 5 August, the heavily laden barge will start its journey through the Nieuwe Waterweg canal to the Borssele I wind farm area. Here, a special crane vessel will install the jacket on the seabed, which is planned for the period from 6 to 16 August. Wilfried Breuer, member of the TSO’s Executive Board and Managing Director TenneT Offshore, comments on the progress of the Borssele project: “I am proud that we can make such a major contribution to the energy transition, in which offshore wind energy plays a crucial role.”
