CACM Cost Report of 2020 / 5 Introduction
All Nominated Electricity Market Operators (NEMOs) The aim of Single Day-ahead Coupling (SDAC) is to cre- and all transmission system operators (TSOs) report to ate a single pan European cross zonal day-ahead elec- the regulatory authorities on the costs of establishing, tricity market. An integrated day-ahead market will amending and operating single day-ahead and intraday increase the overall efficiency of trading by promoting coupling according to the Article 80 of the Commission effective competition, increasing liquidity, and enabling Regulation (EU) 2015/1222 of 24 July 2015 – CACM Reg- a more efficient utilisation of the generation resources ulation. Costs directly related to single day-ahead and across Europe. SDAC allocates scarce cross-border intraday coupling shall be clearly and separately iden- transmission capacity in the most efficient manner by tified and auditable. The report shall also provide full coupling wholesale electricity markets from different details of contributions made to NEMO costs by TSOs in regions through a common algorithm, simultaneously accordance with Article 76(2). considering cross-border transmission constraints and thereby maximising social welfare. SDAC began as a Description of the Single Day-ahead Coupling voluntary initiative from NEMOs and TSOs in 2014 with

• Joint NEMOs and TSOs: governed by the Single Day- Ahead Coupling Operations Agreement (DAOA); • Only NEMOs: governed by the All NEMO Day-Ahead Operation Agreement (ANDOA); • Only TSOs: governed by the TSO Cooperation Agree- ment for Single Day-Ahead Coupling (TCDA).
Therefore, the governance structure is headed by a Joint Steering Committee (JSC) that includes representatives of all the parties involved. The JSC activities are supported by horizontal groups which address the legal, financial and communication aspects of the coupling. Further- more, there are three joint groups which address the following operational aspects: Market & System Design, MRC members (operational*) 4MMC members (operational) Procedures and Operation. In addition, in autumn 2020, *Bulgaria, SEM bidding zone: operation in isolation the 15 minutes Market Time Unit (MTU) coordination was established as a project under the JSC.
