Region, Go-live for the Bulgaria-Romania day -ahead market coupling project is reconfirmed for 27 October

28.Nov 2021.

Following successful completion of all testing activities, the go-live for the Bulgaria-Romania day -ahead market coupling project is reconfirmed for 27 October.

Bulgaria-Romania market project consists of the NEMOs and TSOs of Bulgaria and Romania, namely IBEX, OPCOM, ESO and Transelectrica, and aims to connect the RO-BG border in the European Single Day-Ahead Market Coupling (SDAC) as foreseen by EU Regulation 2015/1222 CACM (guideline on Capacity Allocation and Congestion Management), allowing implicit allocation of the cross-zonal transmission capacity and the electrical energy.

SDAC allocates scarce cross-border transmission capacity in the most efficient way by coupling wholesale electricity markets from different regions through a common algorithm, simultaneously taking into account cross-border transmission constraints, thereby maximizing social welfare.

The aim of SDAC is to create a single pan European cross zonal day-ahead electricity market. An integrated day-ahead market increases the overall efficiency of trading by promoting effective competition, increasing liquidity and enabling a more efficient utilization of generation resources across Europe.
