The Taccani Power Plant is located on the Adda River, within the Adda Nord Park, at the base of the rocky promontory that marks the river bend known as Trezzo. On top of this, stand the ruins of the castle built in 1370 by Barnabò Visconti on the ruins of an earlier Lombard structure. The plant, constructed between 1903 and 1906, was designed by architect Gaetano Moretti, who was commissioned by industrialist Cristoforo Benigno Crespi (1833-1920), owner of a famous cotton mill and founder of the Crespi Village (now a UNESCO World Heritage Site), to build a hydroelectric plant that would provide energy for the cotton mill while also blending into the surrounding environment. In the mid-1990s, a significant technological and environmental improvement and modernization project was undertaken, restoring the plant to full efficiency and safety, while maintaining high reliability standards. Today, the plant operates six turbine/alternator units, consisting of four propeller turbines and two Kaplan turbines, capable of generating flows of up to 180 m3/sec. Efficient power is approximately 10,500 kW, and the average energy output is approximately 65 million kWh, sufficient to meet the annual needs of over 24,000 families. Not only is the Taccani Power Plant today a unique place to visit for lovers of industrial archaeology, hydraulic engineering scholars, and anyone who enjoys discovering unique sites linked to the area's economic and manufacturing history, but it also offers an exceptional venue for prestigious events.
