Relations with companies using the electricity service

in

Terna mainly deals with companies operating in the electricity industry and belonging to one or more of the following categories:

  • distribution companies, with which Terna regulates the energy transmission service on its own grid;
  • dispatching users, i.e. producers, end customers, or wholesalers with which Terna regulates the dispatching service;
  • interruptible customers, i.e. end customers of withdrawals that grant Terna the right to interrupt their load;
  • owners of production plants and owners of grid segments, to which Terna must guarantee the right to connection in compliance with regulatory and technical provisions.

Relations between industry companies and Terna are mainly regulated by the industry Authorities and are defined technically and commercially in the Grid Code.

In particular, with regard to the dispatching service, Terna regulates with the users of the injection dispatching service the economic items regarding procurement of the resources necessary to safeguard the security of the National Electricity System, thus maintaining the equilibrium between injections and withdrawals, as well as ensuring that grid parameters, such as voltage and frequency, are at appropriate levels.

The economic items regarding procurement on the dispatching service market (“MSD”) and other injection side system charges are negative and in 2012 amounted to about 2.2 billion euro.

System charges relative to withdrawal dispatching, mainly composed of the Uplift payment for the MSD resources procurement, are positive and in 2012 amounted to about 2.9 billion euro.

Moreover, with the users of both injection and withdrawal dispatching users, Terna regulates the economic items regarding imbalances, understood as the difference between the plans the users presented on the electricity markets and the actual value of the electricity injected or withdrawn. As regards injection, the amount comes to about 0.2 billion euro (asset for the operator) while the amount relative to withdrawal comes to about 0.1 billion euro (liability for the operator).

Most of the interactions with electrical operators are managed through a platform created to optimize the commercial relationship with the counterparts: the My Terna Portal.

The portal represents the main access channel for services dedicated to operators, from management of the database for requests for connection to the NTG, to the stipulation of withdrawal contracts, to management of contacts, to the display of the principal data for every operator. The system provides for a front office and a back office controlled with a single instrument which allows processes to be tracked and for monitoring of progress status for procedures, using e-tickets.

To meet the needs of operators, the portal home page  – accessible at the www.terna.it site – provides a manual for users an e-mail address that can be used for requests for clarifications and reports of any problems during the registration and utilization phase.

In 2012, Terna procured resources for the interruptibility and instant load reduction services aimed at making functioning of the National Electric System secure in the event the resources procured on the market turned out to be insufficient. In 2012 there were 234 assignees of the interruptibility and instant load reduction service for about 4,346 MW of power and the related negative economic item amounted to about 0.6 billion euro on an annual basis.

The Gaudì Portal

In 2011 the Gaudì (Management of the Single Database of the Plants) portal was implemented, created through the integration of the three main database archives managed by Terna: CENSIMP for the surveying of plants, RUP relative to the database of the Significant Production Units(1) and UPN6 relative to the database of non-significant production units.

The system, which was established by special provisions of the Electricity and Gas Authority, allows technical data for all plants and electricity production units to be received and archived. The goal is to centralize the registration data for all production initiatives carried out and being carried out within Italy with the transmission system operator for their grid manger activities, which involve only a small number of operators, regardless of the size and type of plant, thereby ensuring a complete and constantly updated database.

In 2012 there was an evolution in the qualification process for the plants managed through the Gaudì platform. The process, in accordance with the project road map established by Resolution AEEG 148 of 2011, underwent the following revisions: management and validation of the database also for purposes of measurement, reclassification of GSE commercial types and introduction of the most important features needed to manage the entire life cycle of the plants in operation.

In total there are over 500,000 plants registered in the system, of which more than 150,000 in 2012 alone. A toll-free number and a special e-mail address were activated to manage operator requests and reports. In 2012, a total of 36,121 calls and 20,137 emails were received. During the first few months of 2013, in line with what happened the preceding year, Terna planned three meetings - throughout Italy - with the operators and users interested in using the portal to explain Gaudì registration and user procedures.

The objectives set for 2013, are: total alignment of master data with the Distributors and GSE, complete integration of the process with Terna Group's company systems that use data of plants and production units in operation, the implementation of proper reporting that, as well as providing information on the status of the data, is capable of illustrating growth trends in the various energy production sectors.

(1) Significant production units are production units with overall power of the associated generation groups of not less than 10 MVA.
