The day-ahead market bids for purchase and/or sale of electricity from all participants were accepted for auction and traded successfully - without any regard whether they were market participants - from the Czech or from the Slovak Republic.

Short-term electricity market organizers, the Operátor trhu s elektrinou, a.s. (OTE) in the Czech Republic and Slovenská elektrizacná prenosová sústava, a.s., (SEPS, a.s.), the transmission system operator and organizer of day-ahead electricity market in the Slovak Republic, in co-operation with CEPS, a. s., the Czech transmission system operator, have integrated with success the two national day-ahead electricity markets.
