The 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 2009, Terna continued with many initiatives for reducing the environmental impact of its plants. In particular:

  • on January 13, 2009, Terna signed an agreement with the WWF to maximise the environmental focus of plans to develop the electricity grid. This is the first protocol of understanding that the WWF has signed in Italy with a leading national infrastructure enterprise. The main objectives of the agreement are greater integration of environmental criteria at the national electricity grid development planning stage, along with a harmonisation of these activities with the eco-regional conservation strategy promoted by the WWF. The three-year deal calls for a special jointly-prepared action plan to foster the sustainable development of the electricity grid in WWF sanctuaries, with a view to minimising environmental impact;
  • Terna S.p.A. has signed important Memoranda of Understanding with the regions of Valle d’Aosta, Liguria and Lazio regarding the use of SEAs by the Grid Operator in preparing the development plans for these regions. As a result of these agreements, Valle d’Aosta, Liguria, Lazio and Terna have made a commitment to accelerate and streamline the authorisation process for development projects subject to SEA, and to submit the environmental and local impact of new electricity infrastructures in these regions to prior verification. The approach adopted is based on openness and dialogue with local institutions regarding site placement decisions in order to minimise the environmental impact of electricity infrastructure on local areas;
  • two documents have been signed regarding the sustainable development of the electricity grid in Piedmont. The first concerns construction of the new “Trino-Lacchiarella” power line; the second concerns the rationalisation programme in the city of Turin. Among other things, the work planned includes the demolition of old lines, and infrastructure rationalisation in order to optimise and reduce the impact of these lines on local areas;
  • as part of the grid reorganisation work taking place near Cagliari, operations began on the final stage of removing 150 kV overhead lines at the “Molentargius-Saline” park. This involved the use of specially-modified helicopters to lift 10 pylon bases decommissioned over two years ago out of the Sardinian pond, along with the removal of 12 km of highvoltage power lines within the park;
  • the Rosental Group won first place in the international “Pylons of the Future” contest, which Terna sponsored to encourage the design and planning of new, lower environmental-impact national transmission grid support infrastructure.
    The philosophy behind “Pylons of the Future” contest was to combine innovation, technology, design and environmental awareness in the sustainable development of the national transmission.
