Italian data center firm Aruba has acquired three hydroelectric plants in Turin.The company said the three plants, located in the municipalities of Cafasse, Balangero, and Lanzo Torinese, along the Stura di Lanzo river, generate around 10GWh of renewable energy each year.Announced this week, the terms of the deal were not shared.“Every new plant that joins our facilities portfolio increases the share of clean energy we produce directly and make available to the country's digital infrastructure,” said Stefano Cecconi, CEO of Aruba. “This is a path we have been pursuing consistently for years. Growing in renewable generation means reducing the environmental impact not only of our services, but also of the IT infrastructure that customers choose to install in our data centers. For us, sustainability is not a statement: it is an industrial asset, built plant by plant.”Aruba now owns 11 hydro plants across Italy, with 11.6MW of capacity. The group's total hydroelectric generation capacity is now up to more than 60GWh annually.The plants are located across five rivers in four regions - Piedmont, Lombardy, Veneto, and Friuli-Venezia Giulia.The company acquired two hydro sites, with a combined capacity of 2MW, in April 2023. It previously acquired four plants, with a combined 6MW of capacity, in late 2020. It reactivated a decommissioned microhydro dam in Melegnano in 2024.Aruba added that it recently completed work on a third turbine at the hydroelectric plant inside the Ponte San Pietro (BG) campus.Aruba’s Bergamo campus outside Milan features three data center buildings. The original 17,600 sqm (189,450 sq ft) building offers 8,000 sqm (86,100 sq ft) of colocation space across 10 data rooms and 12MW of capacity. Buildings B and C offer 9MW and 8MW of capacity across 4,950 sqm (53,280 sq ft) and 5,950 sqm (64,050 sq ft) of colocation space, respectively.As well as solar and hydroelectric, the campus infrastructure features geothermal systems. The campus has a capacity for up to five buildings totaling 60MW and 200,000 sqm (2,152,800 sq ft).Founded in 1994, Aruba also operates two facilities in Arezzo and has one in Rome, with another facility in Ktiš in Czechia/Czech Republic.
