Bulgaria-Romania Day-Ahead Market Coupling Project is ready for Go-live on 27 October 2021 with first delivery day on 28 October 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 2021.

Bulgaria-Romania Market Project consists of the NEMOs and TSOs of Bulgaria and Romania, namely IBEX EAD, OPCOM S.A., ESO EAD and CN Transelectrica S.A, 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.

On behalf of IBEX EAD, OPCOM S.A., CN Transelectrica S.A and ESO EAD

About SDAC

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 maximising 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 utilisation of generation resources across Europe.
