The Vatican has announced plans to build a large agrivoltaic power plant that will meet 100% of its electricity needs. This ambitious project, with an estimated cost of 100 million euros, is expected to generate between 80 and 90 megawatts of electricity, making it one of the largest of its kind in Italy. The plant will be located on the extraterritorial domain of Santa Maria di Galeria, 25 kilometers northwest of Rome, covering an area of 450 hectares. This site has been home to Vatican Radio antennas since 1957, and the new project will repurpose the land for renewable energy production. An agrivoltaic power plant combines solar energy production with agricultural activities. In this case, solar panels will be mounted on steel posts that are 3 to 5 meters high, creating space for farming activities such as sheep grazing, vegetable farming, and the cultivation of aromatic plants. The solar panels will be installed on motorized axes, allowing them to rotate from east to west throughout the day to follow the sun’s movement. This design is expected to increase electricity production by 15 to 25% compared to traditional solar panels, which are fixed in one position. The electricity generated will first be used to power the Vatican Radio transmission center, then supply the entire Vatican City. Any surplus energy will be directed to facilities linked to the Holy See, such as the Bambino Gesù pediatric hospital in Rome, or fed back into the Italian electricity grid. The initiative was started by former Pope Francis in 2024 and continues under Pope Leo XIV, who established a foundation in 2026 to support the project. Although the construction has not yet begun, the Vatican is expected to soon issue tenders for the project, with construction estimated to take between 18 and 24 months once a contractor is selected.
