Connection of plants using renewable energy

The main contribution of the 2011 Developmenti Plan to the reduction of CO2 emissions will be due to the connection of plants producing from renewable sources. The production of energy from renewable sources has grown rapidly in the last few years. In particular wind generating plants have considerably increased, especially in southern and insular Italy. During 2010, new wind plants with about 950 MW of installed capacity were commissioned, while photovoltaic plants with about 1520 MW(2) of installed capacity were also commissioned.  

One of Terna’s main tasks is to plan the upgrading of the NTG in order to encourage production of electricity from renewable energy sources by trying to overcome any grid and operating limitations that could condition the injection into the grid of such energy, which is entitled to dispatching priority.   
In this regard, the works included by Terna in the 2011 Development Plan will release about 4,700 MW of power from wind, thus obtaining a reduction of emissions amounting to about 5,000,000 tons of CO2.
