During one of my MTB rides at the Cancano lakes I stumbled into this beatifull dam which is part of the A2A Hydro power of Valtellina : 8 hydro power plants from cancano lakes down to Stazzona near Tirano using water coming from the Adda river and from other 4 different basins :

• San Giacomo : 10MW
• Braulio : 19 MW
• Premadio : 226 MW
• Grosio : 428 MW
• Grosotto/Boscaccia : 13 MW
• Lovero 49 MW
• Stazzona : 30 MW

Adda river continues is ride down to Po river and in the mean time produces some other Hydro power in 4 hydro power plants that have been sold to EDF :

• Bertini : 12,5MW
• Taccani : 11 MW
• Semenza : 7 MW
• Esterle : 32 MW

and then into some other small powerplants :

• Rusca : 7 MW
• Italgen Vaprio : 21 MW
• Crespi (Adda Energia) : No data
• Adda S.Anna : No data
• Fara : 1 MW
• Muzza : 2,5 MW
• Maleo : 4,5 MW
• Pizzighettone : 3 MW

A total of around 900 MW of clean, renewable, hydroelectric power!
