Publications on HDVC reliability and the balancing market


The European Network of Transmission System Operators for Electricity (ENTSO-E) has adopted positions on two systemically relevant topics for the European energy market: the electricity balancing market and the improvement of high-voltage direct current (HVDC) system reliability. Two respective papers have been released by ENTSO-E. The first, a balancing guideline, gives a simplified overview of the target model of the European balancing energy market and explains the most important concepts and processes associated with this market and the platforms for the exchange of balancing energy products. In addition to the focus on the interaction of the different balancing processes, the legal framework of the target model is also briefly outlined.

In its position paper on HDVC reliability, ENTSO-E recognises HDVC as an increasingly important method of transmitting large quantities of electrical energy for the Europe-wide transmission grid. As new HVDC connections play a key role in the future development of the continental transmission system, the reliability, availability, compatibility and robustness of the technology will be crucial for market and system security. For future challenges, high system security and the needs of an efficient European integrated market, it is essential that the owners of HVDC installations, together with other relevant HVDC stakeholders, focus not only on technology innovation but also on further process development, HVDC network integration studies and the maintainability to be carried out by transmission system operators (TSOs). ENTSO-E strongly supports more efficient cooperation between all HDVC players.

ENTSO-E has released a European electricity balancing guideline as well as a position paper on improving the reliability of HVDC systems  (picture of HVDC Plus IGBT converter modules: Siemens AG,

Nordic TSOs to open RSC in February


The Nordic transmission system operators Fingrid from Finland, Statnett from Norway, Svenska Kraftnät and the Danish TSO and TSC member agreed on their meeting of 16 November 2016 on a common Regional Security Coordinator (RSC) office similar to TSCNET Services based on the system operation guideline approved by the EU member states. The four TSOs wish to intensify their cooperation in terms of regional system operation, system security and the implementation of the new Nordic market for automatic frequency restoration reserve (aFRR).

The Nordic RSC office is to be officially opened in Copenhagen, Denmark, on 1 February 2017. As a service tool of the TSOs it will provide, inter alia, transmission capacity calculations, security analyses and adequacy forecasts. The common aFFR-market will be beneficial concerning the maintaining of good frequency quality and the integration of an increasing amount of renewables into the Nordic power system.

Furthermore, the TSOs announced a “Solution report” as sequel to their “Challenges of the Nordic Power System” report. The new paper will cover aspects of transmission adequacy, generation adequacy, flexibility and inertia and is to be published in June 2017.

System security conference in Erfurt


On the 5th and the 6th of September, TSC member 50Hertz, one of the four German transmission system operators (TSOs), held its annual system security conference (“Systemsicherheitskonferenz”) in Erfurt, the capital and biggest city of Thuringia, Germany. The theme for this year’s conference was digitalisation as a key to a successful energy transition. More than 165 experts from TSOs and DSOs, energy producers, industry, politics, NGOs and science used the conference as a forum for discussion.
