Tendercapital-backed Cobra Green wins Colleferro approval for 150MW AI data center

Colleferro's town council has approved the 150MW AI data center that Cobra Green Hyperscale has proposed for the Lazio town, Data Center Dynamics reports. Mayor Giulio Calamita, quoted by Il Messaggero, said the unanimous vote showed the administration leading the process, not undergoing it, after two years of administrative work. The vote follows a municipal call for operators to bid on sites in the town.

Construction is expected to start in 2027, though the project still needs final approval from the Italian government. Cobra Green is a Rome-based photovoltaic company founded in 2022 and owned by Irish investment firm Tendercapital. The company expects to employ up to 220 people. Milan-based Lombardini 22 designed the campus. The site covers 5.7 hectares, with server buildings, offices, and grounds. The power plan draws 150MW from grid operator Terna. A further 34MW comes from on-site solar; gas generators cover emergency supply.

That solar figure is just under a quarter of the grid allocation. The Italian grid will carry normal load. The scale of the project suggests it has grown since Tendercapital bought Cobra Green from NV Holding in 2025. At that point the developer's target was 100MW of data center capacity. Supporting solar was to total 60MW. The public record does not say whether this is the same project, adjusted.

If built, it would add to a thin regional market: Lazio has just 11 data centers, most of them in Rome, according to DataCenters.com. The council vote is a meaningful step, but not a construction permit. The public record names no tenant and gives no IT compute capacity. Without those, the project cannot be underwritten.
