Burgas, on the Black Sea, June 18 (BTA) - The project parties of
 the Interim Coupling have announced the successful go-live of
the Interim Coupling solution, the Independent Bulgarian Energy
Exchange said (IBEX). On Thursday for the first time, day-ahead
cross-zonal capacity on the 6 new borders (Poland-Germany,
Poland Czechia, Poland-Slovakia, Czechia-Germany,
Czechia-Austria and Hungary-Austria) has been implicitly
allocated via the Euphemia algorithm.

The successful launch of the Interim Market Coupling is a
necessary condition for the implementation of Bulgaria-Romania
day-ahead market coupling, which is being implemented according
to schedule and is expected to be completed within three months
of its start, IBEX said.

The Interim Coupling project aims to connect the borders of 4M
MC (Czech-Slovak-Hungarian-Romanian market coupling) with the
Multi-Regional Coupling (MRC) by introducing Net Transmission
Capacity (NTC), based on implicit capacity allocation on the
above-mentioned six borders.

This NTC-based market coupling represents a major step towards
the achievement of European Single Day-ahead Coupling. The next
step consists of the introduction of the flow-based capacity
calculation method in the framework of the Core Flow-Based
Market Coupling project, which is the target model for day-ahead
 market coupling.

The 4MMC countries' day-ahead market (Romania Hungary, Czechia
and Slovakia) is now integrated in the Pan-European day-ahead
power market.

The Single-Day Ahead Coupling (SDAC) in the EU 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.
