Day-Ahead Market Coupling - Price Coupling of Regions (PCR) 
 

Full price coupling between allows the simultaneous calculation of electricity prices and cross-border flows across regions which will bring a benefit for end-consumers derived from a more efficient use of the power system and cross-border infrastructures as a consequence of a stronger coordination between energy markets.

This cooperation aims at establishing price coupling of the day-ahead wholesale electricity markets, increasing the efficient allocation of interconnection capacities of the involved countries and optimizing the overall social welfare.

North-Western Europe (NWE) Coupling
project initiated by the Transmission System Operators and Power Exchanges of the countries in North-Western Europe. The 17 partners of this project comprise APX, Belpex, EPEX SPOT and Nord Pool Spot from the Power Exchanges’ side; 50Hertz, Amprion, Creos, Elia, Energinet.dk, Fingrid, National Grid, RTE, Statnett, Svenska Kraftnät, Tennet B.V. (Netherlands), Tennet GmbH (Germany) and TransnetBW from the TSO side.

South-Western Europe (SWE) Coupling
Joint project between the French, Spanish, Portuguese TSOs, Réseau de Transport d’Électricité (RTE), Red Eléctrica de España (REE), Rede Eléctrica Nacional (REN), and the Iberian and French Power Exchanges OMI Polo Español, S.A. (OMIE) and EPEX SPOT, in which are defined the pre-coupling, post coupling and exceptional situations processes that are necessary to allow the implementation of market coupling between France and the Iberian Market.

Italian Borders Working Table (IBWT)
Joint Market Coupling project between the Transmission System Operators (ADMIE, APG, ELES, RTE, SWISSGRID and TERNA) and Power Exchanges (BSP, GME, EPEX, EXAA and LAGIE) of Austria, France, Greece, Italy, Slovenia, and Switzerland, with the support of CASC and ECC. This project aims to define the pre-coupling, post coupling and exceptional situations processes that are necessary to allow the operation of Market Coupling between MRC and the Italian-Borders day-ahead markets.

The Multi-Regional Coupling (MRC)
Pan-European project dedicated to the integration of power spot markets in Europe. It is a cooperation between the Power Exchanges APX, Belpex, EPEX SPOT, Nord Pool Spot and OMIE, and the Transmission System Operators 50Hertz, Amprion, Creos, Elia, Energinet.dk, Fingrid, National Grid, REE, REN, RTE, Statnett, Svenska Kraftnät, TenneT TSO B.V. (Netherlands), TenneT TSO GmbH (Germany) and TransnetBW. The cooperation operates a price coupling of the Day-Ahead wholesale electricity markets, increasing the efficiency of the allocation of interconnection capacities of the involved countries and optimising the overall social welfare. The MRC relies on one single algorithm, calculating simultaneously the electricity market prices, net positions and flows on interconnectors between bidding zones, is based on implicit auctions and facilitated through the Price Coupling of Regions solution. The MRC currently covers countries accounting for 75% of European power consumption.

Price Coupling of Regions (PCR)
Initiative of seven European Power Exchanges (APX, Belpex, EPEX SPOT, GME, Nord Pool Spot, OMIE and OTE), to develop a single price coupling solution to be used to calculate electricity prices across Europe and allocate cross-border capacity on a day-ahead basis. This is crucial to achieve the overall EU target of a harmonised European electricity market. The integrated European electricity market is expected to increase liquidity, efficiency and social welfare. PCR is open to other European Power Exchanges wishing to join. Today, PCR is used to couple the Multi-Regional Coupling, covering 75% of European consumption, and the 4M Market Coupling between the markets of Czech Republic, Hungary, Romania and Slovakia.
