Electricity production from wind energy in Italy is expected to hit 4.3 TWh for 2008, up from 3.7 TWh in 2007 and 2.7 TWh in 2006, says the latest sustainability report published by Italian grid operator Terna. The rise is partly because the grid company is now required to give priority to wind-generated electricity, it says. To enable this more effectively it began using a 72-hour wind forecasting system in January 2008, the report notes. To accommodate more wind-generated electricity onto the network, the operator is also investing in grid expansion and improvement. This includes the construction of a new 380 kV power line between Sorgente on the island of Sicily and Rizziconi in Calabria and the strengthening of electricity interconnection capacity between the island of Sardinia and mainland Italy and between Sardinia and the French island of Corsica. The transmission network in the area between the city of Foggia in the region of Apulia and the cities of Benevento and Salerno in the region of Campania are also scheduled for improvements, the report adds.
