GRTN (Gestore della Rete di Trasmissione Nazionale - Italian Independent System Operator) is a company which was established in April 2000 as part of the process of restructuring of the power system. The process was initiated by Legislative Decree no. 79/99, aiming at fostering liberalisation and competition in a sector of strategic importance for economic development.
The activities of GRTN concern electricity transmission on the high- and extra-high voltage grid (national transmission grid) that it operates under exclusive rights (“concession”). This responsibility is fulfilled through dispatching, i.e. the co-ordinated operation of power plants, national transmission grid, connected grids and ancillary services.
The shares of GRTN are held by the Ministry of Economy and Finance, exercising the shareholder’s rights jointly with the Ministry of Production Activities, which also issues strategic and operational guidelines for GRTN.
As a Group, GRTN set up two companies, of which it is the sole shareholder: AU (Acquirente Unico) and GME (Gestore del Mercato Elettrico).
