On December 31st, 2009, the regional power grid consisted of 10,694 km of 380 kV lines and 11,350 km of 220 kv lines (Source: Direzione regionale della Programmazione Unitaria e della Statistica Regionale).
The Region of Sardinia aims to ensure:
- the stability and security of the network through a considerable strengthening of energy infrastructures,
- the adjustment of the energy system to make it functional to the regional production system,
- the diversification of energy sources to ensure efficient provision,
- decreasing dependence on oil products, ensuring the compatibility of energy-related actions with environmental protection and the harmonization of the power grid infrastructures.
The current distribution and electricity transmission network is interconnected to the National Grid by the following infrastructure:
- a submarine cable connecting Sardinia, Corsica and the rest of Italy (SACOI), its potential being 250 MW;
- a submarine cable connecting Sardinia and Corsica (Sarco), its potential being 50 MW;
- a submarine cable (SAPEI), its potential being 1,000 MW.
As far as renewable energy sources are concerned, Terna SpA data show that between 2000 and 2010, in Sardinia, the percentage of energy produced from renewable energy sources share increased from 1.5% to 15.5%. Over a total of 14,705 FER systems installed on the regional territory until 2011, 99% of them included solar energy (photovoltaic and thermal) facilities, 39 wind power plants, 19 water facilities, 18 bioenergy plants. There is no geothermal system.
The topic of new technologies applied to sustainability in the energy sector is being developing by universities and public research centres.
Due to insularity, wind force and the average annual temperatures, Sardinia's conditions may be favourable for a more efficient use of Renewable Energy Sources.
