Ternai prepares plans for investing in the development of the grid in order to increase its efficiency and to keep up with the evolution of the country’s power plants and consumption. The works that Terna plans and constructs also have positive repercussions on society. In effect, the condition for their construction is that the collective economic benefit they generate is greater than the cost. Every year Terna prepares a Grid Developmenti Plan with the works scheduled for the subsequent 10 years, as well as the progress made on the works planned in previous years.
Since 2008 Terna has submitted its Development plan to the Strategic Environmental Assessment (SEA) procedure, as provided for by the European Union’s Directive 42 of 2001.

Like the previous editions, the 2011- 2020 Development Plan is organized in two sections. The first contains a detailed analysis of the state of the grid and the new development requirements that emerged in 2010, while the second describes the progress made on the works included in the previous Plans. There is also a new part regarding the new infrastructure for the production from renewable sources, pursuant to the License Agreement, which regards grid infrastructure for the development of renewable sources and is aimed at facilitating the achievement of the national objectives with the maximum exploitation of the installed power, while fulfilling the security obligations of the electric system.         

Approved by Terna’s Board of Directors on December 16, 2010, the 2011-2020 Plan was sent for approval by the Ministry of Economic Development on January 28, 2011, while on March 18, 2011 the consultation stage of the proposed 2011 Development Plan and the related Environmental Report began .
To verify the main expectations of our stakeholders, the Plan was submitted for prior assessment by the Grid Users’ Consultation Committee , which expressed a favorable opinion on November 4 with regard to the new works and on December 15 with regard to the Plan as a whole.
