The Mantaro power plant complex ( Complejo Hidroenergético del Mantaro in Spanish ) is located in the Colcabamba district ( Tayacaja province , Huancavelica region ) in Peru . The complex is the largest hydropower plant in Peru (as of March 2015) and consists of three parts: the Tablachaca dam , the Santiago Antúnez de Mayolo power plant and the Restitución power plant .
The Mantaro power plant complex is owned and operated by Electroperú (EP).
history
The first investigations into the use of hydropower on the Río Mantaro were carried out in the 1940s by the Peruvian engineer and physicist Santiago Antúnez de Mayolo . In 1945 he submitted a study for a hydropower plant on Mantaro. In 1961 the Corporación de Energía Eléctrica del Mantaro (CORMAN) was founded with the aim of realizing the project of a hydropower plant on the Mantaro. The construction of the power plant complex began in 1967. The building project was realized in three steps.
First of all, the Tablachaca Dam, Power Plant I and the connecting tunnel between the two were built from June 1967 to October 1973. The first three machines from Power Plant I went online in October 1973. In a second step, additional pressure pipes were installed and in May 1979 the remaining four machines were commissioned. Then the power plant II was built as the last part of the project and in November 1984 an additional three machines were connected to the grid.
Barrier structure
The Tablachaca dam (Spanish: Represa de Tablachaca , ⊙ ) dams the Mantaro , a source of the Río Ene and thus the Amazon . The barrier structure is a concrete arch dam with a height of 77 (or 80) m. The top of the wall is at an altitude of 2697 m above sea level . The length of the top of the wall is 180 m.
From the dam, the water is first directed through a tunnel (length 19.8 km, diameter 4.8 m) and then through three penstocks (length 1.6 km, diameter 3.3 m) to power plant I.
Reservoir
When the reservoir is completely blocked , the Tablachaca reservoir holds 7 million m³ of water. Since the water flow of the Mantaro fluctuates due to the rainy and dry seasons, various dams in the Mantaro river system above the Tablachaca dam are used for regulation, including the Upamayo dam on Lake Junín . The Junín Lake, from which the Mantaro rises, has a total volume of 556 (or 580) million m³ of water - 441 million m³ of this can be used.
Power plant I
The Santiago Antúnez de Mayolo ( ⊙ ) power plant is located near Campo Armiño at an altitude of 1840 m above sea level . The village of Campo Armiño was built specifically for the workers involved in the construction.
The power plant is named after Santiago Antúnez de Mayolo , who carried out the first studies on the use of hydropower on the Mantaro. It has an installed capacity of 798 MW . The power plant started operation with three machines in 1973. The remaining four machines followed in 1979. The annual production in 2009 was 5.369 billion kWh ; this corresponded to 16.3% of the electricity generated in Peru this year.
There are seven Pelton turbines with vertical shaft and four nozzles each in his machine house . Each turbine has a maximum output of 114 MW . The generators have an output of 120 MVA and their nominal voltage is 13.8 kV . The nominal speed of the turbines is 450 / min. In the switchgear , the generator voltage is increased from 13.8 kV to 230 kV using power transformers.
According to the Global Energy Observatory (GEO), both the turbines and the generators were supplied by Ansaldo . According to OSINERGMIN , the turbines were supplied by Riva Calzoni and the generators by ASGEN .
The maximum height of fall is 748 m. The maximum flow rate is 15.78 m³ / s per turbine. The water is then forwarded from power plant I to power plant II via a single pressure pipe (length 500 m).
Power plant II
The Restitución ( ⊙ ) power plant is a cavern power plant with an installed capacity of 210 MW. It was put into operation in 1984. The annual production in 2009 was 1.680 billion kWh ; that corresponded to 5.1% of the electricity generated in Peru this year.
It receives its water from power plant I. From there it is fed to the power plant via a 100 m long bridge tube with a subsequent 800 m long pressure pipe. Below the power plant, the water returns to the Río Mantaro ( ⊙ ).
There are three Pelton turbines with vertical shafts and six nozzles each in his machine house . Each turbine has a maximum output of 70 MW . The generators deliver 82.5 MVA , their nominal voltage is 13.8 kV . The nominal speed of the turbines is 200 / min. In the switchgear , the generator voltage is raised from 13.8 kV to 231 kV using power transformers.
The turbines were supplied by Riva Calzoni and the generators by Ansaldo .
The maximum height of fall is 257 m. The maximum flow rate is 32 m³ / s per turbine.
