Larderello in Tuscany is an absolutely unique place – the "Mecca" of geothermal energy. This landscape, full of natural steam vents and hot springs, was known already in antiquity, and Dante Alighieri allegedly drew inspiration from it to describe hell in the "Divine Comedy". However, the modern history of this place begins in 1904, when Prince Piero Ginori Conti conducted a historic experiment here: he used steam issuing from the ground to power a small generator that lit five lightbulbs. It was the first time in human history that electricity was produced from geothermal energy.
Today's Larderello, managed by Enel Green Power, is a powerful complex consisting of 34 power plants with a total capacity of about 800 MW. It is one of few areas in the world (alongside The Geysers in the USA) where so-called "dry steam" occurs.[12] Water does not issue from the wells, but pure, superheated steam under high pressure, which goes directly onto turbine blades. This eliminates the need for complicated separators, making the process extremely efficient.
Basic project data:
A characteristic element of the Tuscan landscape in this area are huge hyperboloid-shaped cooling towers, which have become an icon of industrial architecture. Despite the industrial character, the region attracts thousands of tourists. A Geothermal Museum operates here, documenting over 100 years of technology history – from simple boric acid boilers (boric acid was formerly obtained here) to state-of-the-art digital systems controlling extraction.
The Larderello complex is proof of the longevity of geothermal resources. Despite over a century of intensive exploitation, thanks to responsible reservoir management and continuous investments in new wells, the power plant still produces about 10% of all geothermal energy in the world, powering millions of Italian homes. It is a living monument of engineering linking history with the future of energy.
