The Campo Moro dams are a pair of hydroelectric-gravity dams situated in Lanzada, in the province of Sondrio, Lombardy (Northern Italy). The two dams are called "Alpe Gera" and "Campo Moro". Alpe Gera, the largest of the pair, was constructed with approximately 1,800,000 m³ of concrete. [1]
Location
The dams of Campo Moro are located in Valmalenco, which is a valley in the Bernina range, a subrange of the Rhaetian Alps, approximately 150 kilometres (93 mi) north of Milan. The closest municipality to the dams is Lanzada (SO), although Chiesa in Valmalenco is the largest and best known nearby.[2] The Campo Moro dams are accessible by car.[3]
Features
Campo Moro dam
The Campo Moro dam is a huge structure composed of two distinct gravity dams, split by a rocky spur. The western side has a stone-built dam, reaching 32 metres (105 ft) in height and spanning 150 metres (490 ft) in length. In contrast, the eastern dam is made of concrete, with a height of 96 metres (315 ft) and extending across 180 metres (590 ft) . The reservoir formed by Campo Moro holds a maximum capacity of 11 million m³ of water. It is fed by the waters collected in the Alpe Gera basin, at an altitude of 2,125 metres (6,972 ft). As this water makes its way towards the Campo Moro power plant, it goes down an average descent of approximately 133 metres (436 ft).[2][4]
Alpe Gera dam
The Alpe Gera dam is an imposing concrete gravity structure with a rectilinear shape that extends for 530 metres (1,740 ft) and reaches a height of 174 metres (571 ft), containing a total volume of 1,700,000 m³. The body of the dam is divided by contraction joints equally separated by 12 metres (39 ft).
On the upstream side of the dam, walls are covered with a coating of sheet metal panels 2 metres (6.6 ft) wide, 1.4 metres (4.6 ft) high and 3 millimetres (0.12 in) thick. Behind them, drainage pipes have been arranged to prevent infiltration, thus completing the drainage system, which also includes a series of holes in the rock. Inside the dam, seventy-two instruments constantly monitor temperatures, while many other devices keep structural stresses under control. Movements on the plane and in height are verified through specific triangulations. The dam is crossed by ten tunnels connected to each other longitudinally. At its highest point, the dam is equipped with one of the highest systems of elevators in Europe, which move vertically for 140 metres (460 ft).[5][6]
History
The Campo Moro barrier, built between 1956 and 1958, consists of two walls separated by a single rocky spur, the east dam and the smaller west dam. The Alpe Gera dam was erected between 1961 and 1964; it’s the wall constructed at the highest altitude at 2,000 metres (6,600 ft) a.s.l. Just a year later, in 1965, the central station was built within an artificial cave. The Campo Moro power station represents only the first of a series built in the Valmalenco and Sondrio area. In 1955, the Lanzada power station was built, followed by the Sondrio station in 1960.[7]
Smaller organisations that specialised in building “micro-stations”, helped with the conversion of energy in areas such as: Chiareggio in 1995, in 2001 on the Lanterna stream, Tornadri. Followed by the construction of three stations in 2002: on the Basci stream, Giummellini, San Giuseppe Entovascos stream, and near the Franscia on the Scerscen stream.[7]
To this day, Valmalenco, 'the valley of water', provides fresh water and energy to its region, representing 17% of the regional supply.
Electricity
The Campo Moro lake is one of two artificial sources of hydroelectricity produced in Valmalenco, and the Campo Moro power station is one of three local power stations. The other two are at Lanzada (1000 meters a.s.l) and Sondrio (altitude 300 meters a.s.l).[2]
Catchment Area
The Fellaria Glacier is located in Valmalenco above Lake Gera. The glacier's ice melts into Lake Gera and provides the water used by the power stations.[8] The Fellaria Glacier is on the plateau of Fellaria, where the maximum altitude reached by the glacier is 3,500 metres (11,500 ft) a.s.l. The Bernina range, located east of the Gotthard Pass (Switzerland), is partly home to the largest glacial mountain range in Italy. Together with summits such as Mount Cevedale (3779 meters a.s.l.), Mount Adamello (3539 meters a.s.l.), and Piz Bernina (4049 meters a.s.l.), the last being home to the Fellaria glacier.[9]
The Scerscen Glacier, located on the border between Switzerland and Italy, is another water resource of the Alpe Gera basin.[10]
Campo Moro power station
The Campo Moro power station is situated at 2,000 metres (6,600 ft) a.s.l. and was constructed in 1965. It was built inside an artificial cave that is linked to the outside by a 570-metre-long (1,870 ft) gallery. It produces approximately 33 million kwh a year, which provides for the annual needs of 14,000 households.[2] The water used in the electricity generation unit is returned to the Campo Moro reservoir and redirected towards the Lazanda power station by an 8,000-metre (26,000 ft) tunnel.[11] The energy production of the two artificial reservoirs makes Valmalenco and the Sondrio region Italy’s largest producers of hydroelectric energy, with 12% of the national supply, and provides energy to Milan and its province.[12]
Lanzada power station
The 'Alfredo Pizzoli' hydroelectric plant, also called Lanzada power station, is situated in Lanzada at 1,000 metres (3,300 ft) altitude a.s.l. It is the second component of the Valmalenco hydroelectric system, which derives its energy from the Alpe Gera and Campo Moro dams.[13] The Lanzada power station is owned by Enel and has a capacity of 190.7 MW and It can produce on average around 300 GWh per year, which can supply 111,000 families annually. The power station was constructed between 1957 and 1962 and is still active today. The power station has three turbines. It uses the two reservoirs and the water coming from the Compo Moro power station to produce electricity.[14]
Sondrio Power station
The Sondrio power station, located in Sondrio, Italy, stands as a testament to the architectural prowess of Giovanni Muzio. Design and construction took place between 1959 and 1960, commissioned by the Società Edison, now used by Enel Energy. This hydroelectric power station is a distinctive blend of functionality and aesthetics, with Muzio choosing to integrate the structure seamlessly into the surrounding mountainous landscape. The building emerges as a grand glass portal, serving as the terminus for the entire system connected to the Campo Moro reservoir, linked to the Lanzada power station.[15]
Alpe Gera Lake
The lake of Alpe Gera supplies the Valmalenco power stations with water. It is located in Italy's upper Valmalenco region, is one of the country's largest man-made reservoirs, and is placed at an altitude of over 2,051 metres (6,729 ft) a.s.l. with a surface area of 1.15 square kilometres (0.44 sq mi).[16]
Mountain huts
Rifugio Zoia
Constructed in 1929 and renovated in 2007, Rifugio Zoia stands at 2,021 metres (6,631 ft) a.s.l in the Bernina Range. the Refugio is accesible by walk (5-minute) from the parking area near the Dams. It is a starting point for climbers and hikers, and connects to trails of varying difficulty in Valmalenco.[17]
Rifugio Bignami
Rifugio Bignami is located above Lake Gera and overlooks the eastern Fellaria glacier. It is frequented by trekking practitioners, mountaineers and alpine skiers.[18]
Rifugio Poschiavino
Rifugio Poschiavino is located in Campo Moro and it is a starting point for the excursions of the Bernina group.[19]
Recreational activities
Cycling
- In 2018 Campo Moro was included in 'Cycling the Dams', a collaborative sustainability project by Il Sole 24 Ore and Enel.[12]
- The Bike ride start in Chiesa in Valmalenco, goes thru Lanzada and Campo Franscia to finally reach the Campo Moro car park after a 16 kilometres (9.9 mi) ride. From the car park, you can go upward to reach the dams where you can admire its high mountain views with peaks and the glacier (Fellara Glacier). From the dams, it is possible to pick the route 41 and go for rough track (Piz Bernina) and trails or go back to Chiesa in Valmalenco.[20]
Visit tours
- The Lanzada power station is open to the public for visits for people to see how water power functions. It is a collaboration with Enel and the Sondrio and Valmalenco tourist consortium.[13]
Hikes
Campo Moro is known to be a starting point for a large number of hikes:
- The ascendance of the Piz Bernina summit (4049 meters a.s.l). The hike begins from the Compo Moro dams.[3]
- The hike leading to Campo Franscia. This climb is characterized by a gradual, constant gradient leading up to Campo Franscia. It leads to brief tunnels that guide to the parking areas of two mountain lodges at Campo Moro, situated near the Campo Moro artificial basin.[21] In the distance, the prominent Alpe Gera dam becomes visible, offering the option to venture there to appreciate its elevated mountain views adorned with peaks and glaciers. It also starts from the Campo Moro, traversing two dams, passing under the second one.[22]
- The itinerary from Campo Moro to Chiareggio offers a hike accessible to all levels of hiker, showcasing the varied landscapes of the Via Alpina, such as turquoise lakes, pastures, and dense woods. Hiking time is approximately six hours and thirty minutes. The route has a vertical descent of 400 metres (1,300 ft). The starting point is the Zoia hut (2021 meters a.s.l) in Campo Moro. The final stretch leads to Chiareggio (1612 m), the starting point for mountaineering itineraries in the Ventina-Disgrazia Group.[23]
