Austrian-Slovenian Market Coupling


In a joint press release together with power exchanges BSP and EPEX SPOT, the two TSC members APG, the Austrian transmission system operator (TSO), and ELES, the Slovenian TSO, informed about progress in the coupling of the power markets from Austria and Slovenia. The project following the European target model for day-ahead Capacity Allocation and Congestion Management is scheduled to go live in mid-2016.

Operating at full capacity


A conceptual task force (CTF) consisting of dedicated experts at TSC has developed a coordinated intraday capacity calculation (IDCC) concept. It proposes an advanced hybrid-coupling model and takes account of the requirements set by the capacity allocation and congestion management (CACM) guideline for the implementation of a single energy market across Europe. Although the concept is based on flow-based (FB) capacity calculation, it allows the use of available transfer capacities (ATCs) as well.

The concept describes two high-level business processes for IDCC, one based on a day-ahead common grid model (CGM), and the other based on intraday CGMs. A key element in the IDCC concept is the availability of information close or at least closer to real-time. In this context, the task force developed a new GSK methodology (generation shift key/s). The conceptual work is to be followed by a proof-of-principle stage. The concept serves as a starting point for a coordinated IDCC concept supported by the European transmissions system operators (TSOs).

CWE FB MC successfully went live


This is an important milestone for the CWE region (“Central Western Europe”: (Belgium, France, Germany, Luxembourg, the Netherlands) as a part of the European grid: Yesterday evening, a TSC operator at TSCNET Services in Munich, Germany, started the flow-based (FB) CWE computation and officially fired the starting pistol on the FB Market Coupling (MC) processes. So today is the first trading day using FB parameters for coupling, following the approval by National Regulatory Authorities (NRAs) on the 23rd of April.

FB MC helps to enhance the usage of the grid infrastructure and increases the price convergence. As of now, TSCNET performs all the computations in this regard and facilitates all the related operations for the TSC member TSOs within the region (Amprion, TenneT, and TransnetBW). All the procedures and steps of calculation had been screened for several months during a parallel run phase prior to the go-live.

Rapt attention: People at TSCNET’s operator room during the go-live – it worked!
