Environment

The most evident sign of Terna's operations is the physical, visible presence of power lines and stations across the country. To minimise this, Terna has developed a management system for monitoring and limiting the environmental impact of its operations. The Company has placed special emphasis on transmission infrastructure development activities. In this field, Terna has chosen to work with local institutions and harness Strategic Environmental Assessments (SEAs) to take environmental requirements into account right from the earliest stage of new line planning. This makes it possible to identify optimal solutions that combine the needs of developing the electricity grid with the need for protecting the environment and local cultural heritage.

In 2010, Terna continued with many initiatives for reducing the environmental impact of its plants. In particular:

  • it celebrated the International Year of Biodiversity, implementing interventions of environmental restoration, mitigation and offsetting in the two WWF oases of Tuscany of Padule-Orti Bottagone (LI) and Stagni di Focognano (FI), and in the Sicily oasis of Torre Salsa (AG), envisaged by the three-year agreement signed with WWF Italy in January 2009. In December 2010, a new Terna-WWF convention was signed for the development of the first Action Plan for the Sustainability of the Development of the National Transmission Grid in the areas of high environmental value within the national park of Pollino (Region of Calabria and Region of Basilicata) and the National Park of Gran Sasso - Laga (Region of Abruzzo).
  •  In November 2010, the first single-shaft tubular pylons were assembled for the new Chignolo Po-Maleo 380 kV power line in the provinces of Lodi and Pavia. The tubular supports are an important innovation in the development of high and very high voltage lines. The compact structure guarantees that minimum dimensions are required and provides a valid alternative, in given landscape conditions, to conventional pyramid-truncated supports. The prevalent use on the new line of single-shaft pylons in lieu of the traditional pyramid-truncated versions reduces the area of the territory taken up by the lines 5 times and the area covered on the ground by the supports, going from 250 to 50 m2.
  • Terna's attention to CO2 emissions continues. According to the “Carbon Disclosure Project - Italy Report 2010”, prepared on the basis of a survey carried out amongst the top 60 Italian companies in terms of Stock Exchange capitalisation, Terna came in second place in the classification of the Italian businesses most aware and involved in climate change and most transparent in communicating the measurement of its emissions, thereby entering the Italian Carbon Disclosure Leadership Index. Terna's performance is even more significant, as it is not an electricity production company and therefore adopts containment policies on an entirely voluntary basis.
