The “Balancing” section includes data regarding the Dispatching Services Market (MSD). This spot market is the tool through which Terna acquires its supply of resources for the dispatching services as solving congestion, building adequate storage margins and keeping the balance between injection and withdrawal. Acquiring the above-mentioned services is necessary for safely managing the National Electricity System, guaranteeing the proper grid standards, such as voltage and frequency.

Submitting offers on the Dispatching Services Market occurs in a single session immediately following the announcement of the results of the Adjustment Market (MA) [from 2:30 pm to 4:00 pm of D-1] while the selection of the quantity to be accepted is carried out by Terna in two subsequent phases:

  • Planning phase or ex-ante Dispatching Services Market [day D-1 from 4:00 pm to 9:00 pm] 
  • Real time or ex-post Dispatching Services Market [day D]

The market structure established by the existing regulatory provisions does not allow to differentiate offers according to the type of service and also establishes the publication of real time data within the fifteenth day of the m+2 month.
