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.
