Market Coupling - Intraday Market

OTE, a.s (hereinafter 'OTE', Market Operator) as a Nominated Electricity Market Operator ('NEMO') in the Czech Republic cooperates with other European NEMOs to implement the Single Day-Ahead (‘SDAC’) and Intraday (‘SIDC’) Electricity Market Couplings across Europe, as set out in the European Commission Regulation 2015/1222 of 24 July 2015 (CACM Regulation) establishing a guideline on capacity allocation and congestion management. OTE representatives are thus actively involved in individual market coupling projects.

Market coupling (SDAC and SIDC), 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 market 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 unregulated electricity prices, resulting in lower overall costs of electricity.

Here are the projects that contribute to the implementation of the Single Intraday Market Coupling in which OTE participates:
