The renewable energy sector in Italy has been buzzing with activity, and the latest announcement has added fresh momentum. On September 4, 2025, PLT Energia confirmed the acquisition of the 50 MW Castelvetrano solar PV plant in Sicily from X-ELIO. While the deal value has not been disclosed, the strategic move signals PLT Energia’s ambition to strengthen its position in the Italian renewable energy market. This milestone also highlights the growing collaboration between two major players committed to Italy’s clean energy transition.

The acquisition of the Castelvetrano solar PV plant represents more than just an expansion—it’s a deliberate step toward building an integrated platform on a national scale. PLT Energia has set a clear goal of reaching 365 MW of installed capacity by the end of 2025, with 110 MW currently under construction and a robust pipeline of approximately 3.4 GW, including 600 MW already authorized. By bringing this new asset into its portfolio, PLT Energia is aligning itself with Italy’s decarbonization goals while reinforcing its presence in a highly competitive energy market.

Nestled in the Agro di Castelvetrano in Sicily’s Trapani province, the solar plant spans roughly 80 hectares and connects to Terna’s “Castelvetrano” 150 kV substation. Once operational in 2025, it is expected to generate about 92 GWh of renewable energy annually—enough to power thousands of households with clean electricity. The project has passed rigorous environmental and regulatory assessments, gaining Single Authorization in May 2021 from the Ministry of Ecological Transition. With favorable reviews and full permitting, the plant is poised to make a meaningful contribution to Italy’s renewable capacity and long-term sustainability targets.

Unlike many renewable assets tied to long-term contracts, the Castelvetrano solar plant’s electricity will be sold on the merchant market. This approach leverages PLT Energia’s strong expertise as an electricity trader in Italy, Spain, and Texas. By tapping into market-based opportunities, the company can maximize revenues while supporting grid flexibility. Meanwhile, X-ELIO continues to reinforce its Italian portfolio with 146 MW already operational, 116 MW under construction, and a pipeline of 1.1 GW in solar alongside 1.8 GW in energy storage. Together, these developments signal a more dynamic and collaborative renewable landscape in Italy.

The Castelvetrano acquisition reflects how strategic partnerships and market-driven approaches are shaping the future of Italian energy. With construction underway and operations expected to begin in 2025, this project marks an important step in PLT Energia’s journey to scale up its renewable footprint. As Italy races toward its decarbonization goals, the Castelvetrano solar plant stands as a shining example of progress in action.
