The Morcone project in the Benevento province in the wider area of Naples will have an installed capacity of 57 MW.
Nineteen turbines of the 3 MW class from Danish manufacturer Vestas will be installed.
Morcone was the largest project awarded by the Italian government at an auction in 2016.
E.ON is currently building the roads and laying the foundations for the first wind turbines in the mountainous terrain around the communities of Morcone and Pontelandolfo.
In the summer, the turbines will be installed, which will finally go into operation at the beginning of 2019.
In Italy, E.ON owns and operates ten windfarms with a total capacity of around 330 MW in the regions of Sicily, Calabria, Basilicata, Sardinia, Tuscany and Campania.
