The market coupling implements a decentralized approach where each PX manages its
bargaining system and has the right (obligation for the PX Coordinator and the Back-up
PX Coordinator [1]) to implement its own market with a common matching algorithm taking
into account the global model of the network defined by the European TSOs for the
respective markets. Consequently:
- the operators of the Italian and other European markets submit offers/bids in the
bargaining system of their local PX;
- each TSO communicates the information regarding the daily values of the ATC on its
borders to its local PX;
- the PXs (including GME):
- (anonymously) share all necessary information regarding
the offers/bids of their operators;
- share all the necessary information concerning the values
of the ATC;
- the PX acting as a Coordinator and the PX acting as a Coordinator of back up run
the market;
- the PXs that do not act as a Coordinator or as a Coordinator of back up can run
the market;
-
at the end of the market running, the PX acting as a Coordinator distributes the
results to all other PXs that verify their consistency and publish them.
[1] For full members in the PCR, there are figures such as the Coordinator,
the Back-up Coordinator and Operator. The Coordinator is the PX that for a given
market session has to coordinate the activities of the PXs and verify the correctness
of the procedures performed and the results obtained. The Back-up Coordinator is
the PX that is ready to take over the Coordinator where it has problems in performing
this role. The Operators are the other PXs.
