Revised Network Development Plan for Germany

04.02.2019

The four German transmission system operators (TSOs) and TSCNET shareholders 50Hertz, Amprion, TenneT and TransnetBW today have published the first draft of the new 2019 version of their “Network Development Plan (NDP) 2030” on their joint NDP website. All the different scenarios of the NDP meet the German official 65 percent target for renewables in gross electricity consumption, but differ in terms of the use of innovative technologies, storage technologies and flexibility options. Irrespective of this, a further increase in the internal German electricity market gap can be observed in all scenarios – with cumulative generation in the north and consumption centres in the south and west.

In response to the increase in required transport capacity estimated at around 11GW – due to the expansion of renewables, the significant reduction in the use of coal for electricity generation and the development of the European electricity market – the TSOs consider the construction of two additional major DC lines with a total length of 1160km to be necessary. These two extra lines with a total capacity of 4GW were not part of previous NDPs and go beyond the current German Federal Requirements Plan. The new lines are foreseen to run as underground cables in a corridor from the federal state of Schleswig-Holstein via Lower Saxony and North Rhine-Westphalia to Baden-Württemberg. They are part of the scenario B 230, in which the German TSOs propose to build altogether more than 4500km of new or upgraded power lines by 2030 (the abovementioned 1160km of the new DC lines plus an additional 450km of new constructions and 2900km of upgrades).

The costs for the expansion of the German extra-high voltage grid in the B 230 scenario will rise significantly as a result of the new projects. The TSOs estimate the costs at around €52bn. As in previous years, the Offshore Network Development Plan was drafted together with the NDP and integrated into the new NDP 2030. The NDP publication marks the start of a four-week public consultation. The comments will be taken into account for the second draft of the NEP 2030, which will then be submitted to the Federal Network Agency for review. The Agency is expected to announce its modified plans probably in May, after which the Federal Government will have to confirm the expansion in the official Federal Requirements Plan.

TSOs release data under open license

03.02.2019

The European power transmission system operators (TSOs), represented by the European Network of Transmission System Operators for Electricity (ENTSOE), have agreed on a new data policy for the reuse of TSO owned data. This new policy implies that the TSOs release their data on ENTSO-E’s Transparency Platform under an open data licence.

This allows TSO data to be easily reused for new services, research and applications, such as the “Wind Europe Map” and “Tomorrow’s Electricity Map” – just two examples of how the open TSO data can be used to better inform citizens about energy transition and to develop new services and transparency in general. The TSOs and ENTSO-E thus demonstrate their commitment to providing sound and reusable facts and figures to energy market players and the public.

APG study on targets for renewables

31.01.2019

A resilient electricity transmission grid is the most effective flexibility option for converting the energy system in the course of the energy transition. This is the result of a study conducted by the renowned consulting company “Energy Brainpool” on behalf of TSCNET shareholder APG, the Austrian transmission system operator (TSO). The aim of the study is to identify possible effects of the restructuring of the energy system and concrete measures so that Austria can sufficiently contribute to the international climate agreement. According to “Mission 2030”, the Austrian energy and climate strategy, the national target in this respect is to cover 100% of electricity consumption with renewable energies by 2030.

“A full focus on renewables is the only reasonable way,” states Gerhard Christiner, CTO at APG. “We fully support the political goals of the Austrian Federal Government.” Since the transformation of the energy system is a comprehensive project, it can only be realised with enormous effort of all parties involved. The new study shows that the expansion of renewables will lead to unprecedented volatility in power generation, which should best be countered with a strong transmission grid. The basic precondition for this is the rapid implementation of the existing grid extension plans.

“The APG grid development plan provides for an investment volume of more than two and a half billion euros over the next ten years to upgrade our infrastructure,” explains Thomas Karall, CFO at APG. That’s money well spent, for the results of the “Energy Brainpool” study show that, in principle, it is possible to achieve the targets set out in “Mission 2030″. But official approval procedures must be accelerated, because: “If we do not manage to extend the transmission grid on time, the energy system will reach its limits. Then it will not be possible to fully exploit the potential of renewable energies,” explains CTO Christiner.

Swissgrid responds to legislative revisions

31.01.2019

The Swiss Federal Electricity Supply Act is the most important legal basis for the operations of TSCNET shareholder Swissgrid, the Swiss transmission system operator (TSO). The Swiss Federal Office of Energy began revising this legislative act a few years ago in order to bring it into harmony with the national “Energy Strategy 2050”. Since October 2018, a corresponding consultation procedure on the planned revision of the Electricity Supply Act has been underway. The consultation ends today.

The current revision particularly aims at the full liberalisation of the electricity market and the introduction of a storage reserve. It has stimulated an ongoing debate in Switzerland on the security of supply, which is both necessary and explicitly welcomed by Swissgrid. The TSO also considers that the complete liberalisation of the electricity market will lead to new providers and more innovation, thus having a positive impact on the transmission system and the economy as a whole. In this context, however, it has to be emphasised that liberalisation also places higher demands on efficiency and data quality for the entire electricity sector. Because of this, the availability of timely and reliable data will be crucial for forecasting and monitoring.

With regard to the introduction of a storage reserve, Swissgrid takes a critical stance and generally questions the necessity of a strategic reserve. Reserving existing energy without adding more to the system will not increase supply security. In addition, there are still many open questions about the concrete technical design, but also about the roles and responsibilities in the electricity industry. Swissgrid has the task of operating the grid reliably and efficiently, while the entire electricity industry is responsible for the power supply. Through the activation of a storage reserve, the TSO would indirectly become the last-instance supplier, a role that Swissgrid rejects.

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”.

ACER consultations on CCRs, CSAM and RAOCM

28.01.2019

Two public consultations have recently been launched by the Agency for the Cooperation of Energy Regulators (ACER), both on proposals from transmission system operators (TSOs) affecting core operational areas of the TSO business. National regulatory authorities (NRAs) have delegated the decision on both proposals to ACER, which requests comments from interested stakeholders for a sound assessment.

In December 2018, the relevant TSOs submitted their suggestions on the methodologies for the Coordination of Operational Safety Analysis (CSAM) and for the Coordination of Relevant Power Outages (RAOCM) in electricity. The first ACER consultation refers to these proposals. It is open for all interested stakeholders until 18 February.

The background of the second consultation is the concern of NRAs to adopt some TSO proposals for amendments to the determination of capacity calculation regions (CCRs). Now ACER wants to gather views and information from stakeholders that relate to the latest ACER modifications to the second TSO proposal for amendments of the CCR determination. This consultation is open until 17 February.

ACER, based in Ljubljana, Slovenia, has launched two public consultations on the determination of CCRs and on the methodologies for CSAM and for RAOCM

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.
