Construction progress for Oradea-Békéscsaba line

02.11.2020

In July 2020, the Romanian transmission system operator (TSO) and TSCNET shareholder Transelectrica finally was able to award the construction contract for the missing section of the 400kV Oradea-Békéscsaba power line. For more than ten years, the completion of the overhead line in the far west of Romania has been prevented due to unsettled property issues concerning this section, namely between the Oradea South substation and Nădab. Now that the ownership concerns have been resolved, the investment in the new line will ensure interconnection capacity in the region. Transelectrica expects the construction works to be completed by summer 2021.

Closing this transmission gap is important to Romania’s overall security of supply because the commissioning of the last 72 kilometres between the Romanian town Nădab and the Hungarian border town Békéscsaba not only completes the Oradea-Békéscsaba overhead line, but also contributes to the closure of the “400 kV Ring” in western Romania, a priority energy objective for Romania. The new line will also enable Transelectrica to reduce congestions and thus save considerable intervention costs. As regards European market integration, Romania’s interconnection capacity will be increased by 100MW in export and 300MW in import direction.

The management of Transelectrica represented by the Chairman of the TSO’s Directorate, Cătălin Nițu, and the members of the Directorate, Andreea Miu and Bogdan Marcu, have now informed themselves personally about the progress of the construction work. Mr Nițu emphasised the particular importance of the project for the Romanian energy landscape and the European electricity market

Delay for Interim Coupling

11.09.2020

To introduce single day-ahead coupling in a total of 23 European countries, the so-called 4M Market Coupling Countries (4M MC) – Czech Republic, Hungary, Romania, and Slovakia – are to be connected to the Europe-wide Multi Regional Coupling (MRC) of the electricity market. The initiative to implement the MRC extension is the DE-AT-PL-4M project, also referred to as “Interim Coupling Project”. It aims to establish implicit capacity allocation based on Net Transfer Capacity (NTC) at six borders: PL-DE, PL-CZ, PL-SK, CZ-DE, CZ-AT, and HU-AT. The TSCNET shareholders 50Hertz, APG, ČEPS, MAVIR, PSE, SEPS, TenneT, and Transelectrica – transmission system operators (TSOs) from Austria, Czechia, Germany, Hungary, Poland, Romania, and Slovakia – participate in Interim Coupling.

After the project had completed the design phase and entered the implementation phase at the end of 2019, Interim Coupling was actually supposed to start in September 2020. The TSOs and Nominated Electricity Market Operators (NEMOs) involved have now announced that the kick-off must be postponed. This is due to several project parties experiencing local implementation bottlenecks in the first quarter of 2020 because of interrelations between ongoing parallel projects. This led to a delay of several months in the implementation activities for Interim Coupling. National regulatory authorities have asked the European Commission to provide guidance on how to proceed with this project. Market players will be informed as soon as possible about the next steps.

The start of the AT-PL-4M MC project has been postponed

First successful device installation within FARCROSS

28.08.2020

The FARCROSS (FAcilitating Regional CROSS-border Electricity Transmission through Innovation) project, which started in October 2019, is a four-year project funded by the European Commission under the Horizon 2020 programme. The objective of FARCROSS is to find solutions for increased regional cross-border cooperation in electricity transmission. The connection of regional key players in the energy value chain and the introduction of integrated hardware and software solutions are intended to tap additional resources for cross-border electricity flows. The FARCROSS consortium of 31 partners includes the transmission system operators (TSOs) from Albania, Bosnia and Herzegovina, Bulgaria, and Greece together with the TSCNET shareholders APG (Austria), Hops (Croatia), MAVIR (Hungary), and Transelectrica (Romania).

The three demonstration areas of FARCROSS are smart grid innovations, the development of regional system operations platforms to allow improved system operation forecasting on TSO level, and the optimisation of capacity allocation for regional cross-border trading. The technical grid solutions involve special line monitoring sensors, which are based on the Dynamic Line Rating (DLR) technology for real time overhead line monitoring. These sensors enable TSOs to optimise the utilisation of their transmission lines. The installation of DLR sensors is intended for four countries, and the Croatian TSO HOPS was the first to install such devices on the 220kV Senj-Melina transmission line a month ago. Since then, the sensors have been operating smoothly and the HOPS team of experts is pleased to have taken the first step towards the ambitious FARCROSS goals.

Way is paved for 400kV line in western Romania

29.07.2020

For more than ten years, the completion of the 400kV Oradea-Békéscsaba overhead line in the far west of Romania has been prevented due to unresolved ownership issues regarding the section Oradea South-Nădab. Because of this, the line could only partially be put into operation, that is between the Romanian town Nădab and the Hungarian town Békéscsaba, near the Romanian-Hungarian border. Now the property situation has been clarified and the Romanian transmission system operator (TSO) and TSCNET shareholder Transelectrica was able to award the building contract for the missing section.

Transelectrica expects the construction work to be completed within twelve months. The commissioning of the last 72-kilometre section and thus the completion of the Oradea-Békéscsaba overhead line will contribute to the closure of the “400kV Ring” in the west of Romania. This project is a priority energy target for Romania, which will significantly improve the operational reliability of the national transmission system and security of electricity supply in the north-west of the country. The new Oradea-Békéscsaba line will also enable Transelectrica to eliminate congestions and thus save considerable costs for grid interventions. Finally, Romania’s interconnection capacity will be increased by 100MW in export and 300MW in import direction, which will not only contribute to compliance with EU regulations, but also make a sustainable contribution to the integration of the European electricity market.

Southeast RSC established in Thessaloniki

28.07.2020

The four transmission system operators (TSOs) of the South-East Europe and Greece-Italy Capacity Calculation Regions (CCRs) – which are ESO-EAD (Bulgaria), IPTO (Greece), Terna (Italy), and TSCNET shareholder Transelectrica, the TSO from Romania – have established the sixth European Regional Security Coordinator (RSC) in the northern Greek city of Thessaloniki. The new RSC goes by the name of Southeast Electricity Network Coordination Centre (SEleNe CC). Each TSO participates equally in the share capital of the new company.

SEleNe CC provides all regional RSC services for both CCRs according to the requirements of the EU guideline on capacity allocation and congestion management (CACM). The main tasks of SEleNe CC – just as with Baltic RSC, Coreso, Nordic RSC, SCC, and the Munich based RSC TSCNET Services – are: coordinated security analysis, outage planning coordination, coordinated capacity calculation, (very) short-term adequacy forecasts, individual and common grid modelling, and data set delivery. The Board of Directors of SEleNe CC consists of one member from each TSO with Ioannis Kampouris from the Greek TSO IPTO as Chairman and CEO.

Catalin Nitu, CEO of Transelectrica, comments on the establishment of SEleNe CC: „Improving energy security and cooperation at both organisational and technical level brings us one step closer to an energy-integrated Europe. This step is part of a normal and necessary evolution for regional energy security, in the light of the implementation of the common electricity market’s new model. I express my gratitude to our colleagues and partners who have consistently shown professional excellence and commitment to establish this security centre.”

New Local Implementation Project under SIDC

09.07.2020

European transmission system operators (TSOs) are committed to the European Energy Union by collectively working towards an integrated European electricity market. A key component for market integration is cross-border Single Intraday Coupling (SIDC), which was introduced as XBID in June 2018. SIDC is designed to increase the overall efficiency of intraday trading through effective competition, increased liquidity, and more efficient use of generation resources. Currently, the markets of 22 countries are coupled through SIDC: Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Romania, Slovenia, Spain, and Sweden. With the inclusion of the Slovakian Nominated Electricity Market Operator (NEMO) OKTE and TSCNET shareholder SEPS, the TSO from Bratislava, the project also extends to Slovakia.

Within the framework structure of the SIDC, Local Implementation Projects (LIPs) provide for the expansion of the market coupling, and a new project has now been established as LIP 17. The NEMOs and TSOs from the Czech Republic, Hungary, Poland, and Slovakia – the TSCNET shareholders ČEPS, MAVIR, PSE, and SEPS – have proposed to implement SIDC across the borders between Slovakia-Czechia, Slovakia-Hungary, and Slovakia-Poland. The SIDC Steering Committee approved on 7 July and the LIP 17 roadmap will now be elaborated in more detail.

The SIDC solution comprises a common IT system with a shared order book, a capacity management module, and a shipping module. In addition to the TSOs mentioned above, the TSCNET shareholders 50Hertz, Amprion, APG, ELES, HOPS, TenneT, Transelectrica, and TransnetBW as well as the TSCNET customers Creos from Luxembourg and Energinet from Denmark are also part of SIDC.

SIDC: Massive growth in trading volume

02.04.2020

European cross-border Single Intraday Coupling (SIDC) was introduced in June 2018 (then called XBID) to increase the overall efficiency of intraday trading through effective competition, increased liquidity, and more efficient use of generation resources. The overarching objective is the integration of the European energy market. In November 2019, SIDC was extended in a second go-live, so that currently the markets of 22 countries are coupled through SIDC: Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Luxembourg, Norway, the Netherlands, Portugal, Spain, Sweden (first go-live), and Bulgaria, Croatia, the Czech Republic, Hungary, Poland, Romania, and Slovenia (second go-live).

The Nominated Electricity Market Operators (NEMOs) from the seven countries of the second go-live report significant growth in trading volume in the coupled intraday market. The Hungarian NEMO HUPX, for example, recorded an average monthly trading volume of around 75,600MWh from December 2019 to February 2020 compared to 7,600MWh in the same period of the preceding year; in the Czech Republic, the volume has increased eightfold. The other NEMOs are also registering significant growth rates. A total of 36 million trades have been executed since SIDC first went live, and the system continues to operate reliably after the second wave.

The SIDC solution is based on a common IT system with a shared order book, a capacity management module and a shipping module. The TSOs cooperating in SIDC include the TSCNET shareholders 50Hertz, Amprion, APG, ČEPS, ELES, HOPS, MAVIR, PSE, TenneT, Transelectrica and TransnetBW, as well as the TSCNET customer Creos from Luxembourg and Energinet from Denmark. With the accession of the NEMO OKTE and further TSCNET shareholder SEPS, the TSO from Bratislava, the project has meanwhile been extended to Slovakia. A third go-live to expand continuous cross-border intraday trading to Greece and Italy is expected in the first quarter of 2021.

TERRE platform launched

07.01.2020

The project “Trans European Replacement Reserves Exchange” (TERRE) is dedicated to implementing the exchange of replacement reserves (RRs) under the EU guideline on electricity balancing. The objective of TERRE is to establish the European RR balancing energy market via an RR platform and to create uniform conditions for market participants. TERRE has been confirmed by the European Network of Transmission System Operators for Electricity (ENTSO-E) as the European platform for the exchange of balancing energy from RRs and is closely monitored by national regulatory authorities and the Agency for the Cooperation of Energy Regulators (ACER).

TERRE involves eight European transmission system operators (TSOs). The three TSCNET shareholders ČEPS from the Czech Republic, PSE from Poland and Swissgrid from Switzerland are complemented by RTE (France), National Grid (United Kingdom), Terna (Italy), REN (Portugal) and Red Eléctrica de Espaňa (Spain). A further six TSOs with observer status include the TSCNET shareholders MAVIR from Hungary and Transelectrica from Romania.

The TERRE platform was launched on 6 January 2020. The platform ensures cost-effective balancing energy with service availability within 30 minutes in a European setting. ČEPS was the first TSO to connect to the platform, and is currently also the only one. Further members will follow. “The launch of TERRE represents the completion of several years of effort, from defining business rules to developing an IT solution to testing the system with market participants in Europe,” explains Zbyněk Boldiš, Member of ČEPS’ Board of Directors.
