According to Article 4(10) of CACM Regulation ACER shall maintain a list of the designated NEMOs, their status and where they operate on its website: ACER’s list of designated NEMOs
Besides the NEMOs designated in each Member State, the following NEMOs are active in other countries using the passporting option:
The All NEMO Committee facilitates the cooperation among NEMOs for all common European tasks necessary for the efficient and secure design, implementation and operation of single day-ahead and intraday coupling. The All NEMO Committee is formed by the appointed representatives of each NEMO.
The All NEMO Committee also ensures compliance with the CACM Regulation, the MCO Plan and related contracts and relevant methodologies. It does this by organising periodic teleconferences and/or physical meetings, where discussions and decisions on article 9 of the CACM Regulation take place. According to section 4.2 of the MCO Plan, the All NEMO Committee may create or dissolve working groups or task forces dedicated to managing specific topics, under the responsibility of relevant task force leaders that refer to All NEMO Committee.
The All NEMO Committee also represent official all NEMOs positions in several coordination groups and meetings with TSOs and Institutions (NRAs, ACER, European Commission).
Cooperation is one of the key-words of the CACM Regulation. As a matter of fact, the establishment and efficient management of single day-ahead and intraday coupling process requires a high level of cooperation between Nominated Electricity Market Operators (“NEMOs”), who shall jointly carry out the MCO function based on the principle of non-discrimination (according to Article 7 of CACM Regulation).
To facilitate cooperation among NEMOs for all common European tasks required by the CACM Regulation each NEMO is entitled to sign the All NEMO Cooperation Agreement (ANCA) LINK and join the All NEMO Committee.
Under Article 7 of the CACM Regulation, on 14 April 2016 the Nominated Electricity Market Operators (NEMOs) submitted to all regulatory authorities (NRAs) and to ACER the proposal for a plan that sets out how to jointly set up and perform the MCO functions, including necessary draft agreements between NEMOs and with third parties (the MCO Plan).
The MCO Plan was unanimously approved in its final version by all NRAs on 20 June 2017, and includes:
Under Article 9(6) of the CACM Regulation, on 14 February 2017 the Nominated Electricity Market Operators (NEMOs) submitted to all regulatory authorities (NRAs) and to ACER the proposal for the following terms and conditions or methodologies:
All NEMOs’ proposal for the price coupling algorithm and for the continuous trading matching algorithm, also incorporating TSO and NEMO proposals for a common set of requirements, in accordance with Article 37(5) and 37 (1) of the CACM Regulation (Algorithm Methodology);
All NEMOs’ proposal for products that can be taken into account by NEMOs in single day-ahead coupling process in accordance with Article 40 of the CACM Regulation (DA Products Methodology);
All NEMOs’ proposal for products that can be taken into account by NEMOs in single intraday coupling process in accordance with Article 53 of the CACM Regulation (ID Products Methodology);
All NEMOs’ proposal for the back-up methodology in accordance with Article 36(3) of the CACM Regulation (Back-up Methodology);
All NEMOs’ proposal on harmonized maximum and minimum clearing prices to be applied in all bidding zones which participate in single day-ahead and single intraday couplings, in accordance with Art. 41 (2) and Art. 54 (2) of CACM (Harmonised min-max clearing price methodology);
The proposals were subject to a public consultation (in line with Article 12 of the CACM Regulation).
The details of the approval of each proposal are given in the following table:
|Methodology||Proposed by||Requested to be amended by||Approved by|
|Algorithm||All NEMOs on 14 feb 2017||All NRAs on 24 July 2017. Escalated to ACER on 30 Jan 2018 and consulted by ACER on May 2018||ACER on 26 July 2018|
|DA and ID products||All NEMOs on 14 Feb 2017||All NRAs on 14 August 2017||All NRAs on 24 Jan 2018|
|Back-up||All NEMOs on 17 Feb 2017||All NRAs on 25 July 2017||All NRAs on 24 Jan 2018|
|Harmonized max and min clearing prices||All NEMOs on 17 Feb 2017||Escalated to ACER on 2 Aug 2017, and consulted by ACER on 24 Aug 2017||ACER on 14 Nov 2017|
The Day-Ahead Products, Intraday Products and the Back-up Methodology have been unanimously approved in its final version by all NRAs on the 24 January 2018, while the Harmonised min-max clearing prices and the Algorithm Methodology were escalated by all NRAs to ACER, according to Article 9(11) of the CACM Regulation, respectively on the 25 July 2017 and on the 30 January 2018.
With decisions 04/2017 and 05/2017, ACER adopted the final version of the Harmonised min-max clearing prices to be applied, respectively, to single day-ahead coupling and single intraday coupling.
On 26 July 2018 with decision 08/2018, ACER adopted the Algorithm Methodology, including the two annexes on Day-Ahead common sets of requirements (DA Algorithm requirement) and on Intraday common sets of requirements (ID Algorithm requirement).Algorithm Methodology
