Market Coupling - Day-Ahead market

OTE, a.s (OTE, Market Operator) is the nominated electricity market operator (NEMO) in the Czech Republic and as such cooperates with other European NEMOs to implement single day-ahead and intraday electricity markets across Europe, which is the goal set out in the European Commission Regulation 2015/1222 of 24 July 2015 establishing a guideline on capacity allocation and congestion management (CACM Regulation). OTE representatives are thus actively involved in individual market coupling projects.

Market coupling (day-ahead and intraday), as required by the CACM Regulation, leads to the removal of barriers to cross-border trading and promotes one of the fundamental principles on which European cooperation is based – securing the free movement of goods, persons and services. An energy market divided into individual national markets (though physically interconnected) is inefficient and trading on it is riskier, thus more expensive.

Even though electricity markets coupling is primarily intended to facilitate trading and reduce losses from inefficient use of cross-border capacity allocation, the overall impact is much wider. For traders, thanks to the unification of trading rules, market coupling facilitates access to individual European markets and the expansion of business opportunities. For transmission system operators it increases the efficiency of cross-border profiles. For the end customer, the creation of a single electricity market brings increased security of electricity supply as well as benefits that result from a wider range of suppliers thanks to increased competition in individual markets. In the overall context, this pushes down the unregulated electricity prices, resulting in lower overall costs of electricity.

On the day-ahead market, the projects include All NEMO Committee, Single Day-Ahead Coupling (SDAC), 4M Market Coupling (4M MC), Core Flow-Based Market Coupling (Core FB MC), DE-AT-PL-4M Market Coupling (Interim Coupling) and 15min Market Time Unit.
