This report presents the results of the pre-feasibility assessment for repowering the Nasca Wind Farm, located on San Pietro Island (Sardinia, Italy). To assess the repowering of the existing wind farm, a total of 8 new possible configurations were considered, highlighting the benefits of higher tower heights. The suitability of the existing distribution grid to host the new capacity from the wind farm has been preliminarily assessed by the Distribution System Operator (DSO) of San Pietro: the screening verified that a 2 MW wind farm could be realised in Nasca without the need for significant improvements to the power grid, also when the existing PV plant is repowered to 1.6 MW (+0.6 MW). 

Nowadays, thanks to the PV plant in Nasca and several distributed rooftop PV plants, San Pietro Island has a ~13.5% self-sufficiency of the electrical supply. The wind farm studied in this report has the potential to increase self-sufficiency to a value between 42.3% and 50.7%, depending on the scenario assessed.
