Ternai continues to be a member of Confindustria, the most important association representing the interests of Italian enterprises. In April 2008 Terna also signed a Protocol of Understanding with the ANIE (the National Federation of Electro-technological and Electronic Companies), which is a member of Confindustria. The three-year agreement provides for common initiatives aimed at institutional and financial interlocutors and the operators of the electric grids of other countries of common interest with regard to their respective objectives of international growth. The ANIE undertakes to encourage its members to provide, at Terna’s request, technical advice about foreign markets and to facilitate the exchange of information and statistical data to improve knowledge of markets of interest.  

Terna also participates actively in the CEI (Italian Electro-technological Committee), an organism entrusted with tasks regarding the industry’s technical standards. Terna employees with technical roles often belong to professional associations whose purpose is to keep their members up to date, such as, for example, the CIGRE (Conseil International des Grands Réseaux Électriques) and the AEIT (Italian Federation of Electro-technology, Electronics, Automation, Information Technology, and Telecommunications), which bring together electrical engineers and other industrial specialists.
