    On 19 November 2014 the CZ-SK-HU-RO Market Coupling was successfully launched, integrating the Czech, Slovak, Hungarian and Romanian day-ahead electricity markets and replacing CZ-SK-HU Market Coupling.

    The project started in August 2013 with the aim to extend the CZ-SK-HU Market Coupling towards Romania and to implement the PCR (Price Coupling of Regions) solution. Transmission system operators (ČEPS, SEPS, MAVIR and Transelectrica) together with power exchanges (OTE, OKTE, HUPX and OPCOM) supported by national energy regulators (ERÚ, ÚRSO, MEKH and ANRE) collaborated within the project in order to develop and implement all necessary solutions which ensure technical and procedural compatibility of 4M MC with the target European solution which is already implemented in other coupled European regions. Market coupling allows higher efficiency of trading and capacity allocation, which should lead to higher security of supply, higher liquidity and lower price volatility.
