Vellezzo Bellini sits in the province of Pavia rather than Milan, which is the first thing most directories get wrong about MIL04D. The building carries 24 MW inside a 107,209 sq ft shell — the same footprint as MIL04B, which holds 20 MW — making it the highest-powered of the four buildings on a 64 MW campus off Alzaia Naviglio Pavese. Power reaches the site on a purpose-built dual 132 kV circuit buried for roughly 10.2 km to Terna's Lacchiarella substation, landing at an on-site medium-voltage substation built between November 2023 and May 2024, with 72 MTU 20V4000G24F generator sets of 2,420 kW each and about 1 MW of rooftop photovoltaic behind it. The campus was permitted through Italy's national environmental assessment, procedure 11238, opened in March 2024 by the development company Infrastructure Italia Land 4 S.r.l. and recorded as concluded; Bouygues E&S Italia holds the works package on a build estimated at €41.6 million.
How does MIL04D differ from the other three buildings on the campus?
It carries 24 MW in the same 107,209 sq ft shell that holds 20 MW at MIL04B. MIL04A is 10 MW in 71,364 sq ft and MIL04C 10 MW in 62,646 sq ft, so D accounts for more than a third of the 64 MW campus.
Which province is the campus in?
Pavia. Vellezzo Bellini is a comune in the province of Pavia, Lombardia, and the campus is marketed into the Milan market, which is why it is commonly filed under Milan.
How does the campus connect to the grid?
On a dedicated dual 132 kV circuit buried for about 10.2 km to Terna's Lacchiarella substation, routed through Zibido San Giacomo, Lacchiarella, Binasco, Casarile, Rognano and Giussago, and landing at an on-site medium-voltage substation built between November 2023 and May 2024.
What standby generation serves the campus?
Seventy-two MTU 20V4000G24F sets at 2,420 kW each, tested monthly, drawing on 72 day tanks of 1,000 litres plus additional 30,000-litre storage.
