Dams Along the Paraná River, Brazil

Brazil - May 8th, 2012

The wide, greenish-blue line crossing this image of Brazil diagonally is the Paraná River. Here, the river appears widest and most blue in color behind the Engineer Sérgio Motta Dam, formerly known as the Porto Primavera Dam, in the state of São Paulo, Brazil.

South of the dam, the river forms a natural boundary between Paraguay and Brazil until the confluence with the Iguazu River. Shortly upstream from this confluence, however, the river is dammed by the Itaipu Dam, the second largest hydroelectric power station in the world (after the Three Gorges Dam in the People’s Republic of China), and creating another massive, shallow reservoir behind it.

After merging with the Iguazu, the Paraná then becomes the natural border between Paraguay and Argentina. Here, the outline of Argentina’s Misiones Province is clearly visible as it is darker green than the surrounding land in Paraguay (west) and Brazil (east).

Brazil, Paraguay and Argentina - May 6th, 2012

Near the center of this image are the cities of Foz do Iguaçu, Brazil, and Ciudad del Este, Paraguay, by the triple border between Brazil, Paraguay and Argentina. Flowing towards the cities from the top center is the Paraná River, changing in color from brown with sediments to greenish blue in the large reservoir behind the Itaipu Dam, a hydroelectric dam on the Paraná River.

Visible to the west, near the left edge, is the dark blue Rio Yguazú Lake. To the east, in the dark green vegetated area, the San Antonio River can be observed. It is a tributary of the Iguazu River, and forms the border between Misiones Province in Argentina and Paraná State in Brazil.

Paraguay, Brazil, Argentina - December 29th, 2011

The white area near the top of this image is the city of Foz do Iguaçu, in the Brazilian state of Paraná, by the triple border between Brazil, Paraguay and Argentina. Visible to the north of the city is the reservoir created by the Itaipu Dam, a hydroelectric dam on the Paraná River located on the border between Brazil and Paraguay.

The dam is the largest operating hydroelectric facility in terms of annual generating capacity, generating 94.7 TWh in 2008 and 91.6 TWh in 2009. In 2008 the plant generated a record 94.68 TWh, supplying 90% of the electricity consumed by Paraguay and 19% of that consumed by Brazil.

Visible to the west is the Rio Yguazú Lake, while to the east, the San Antonio River, a tributary of the Iguazu River, can be seen. The San Antonio River forms the border between Misiones Province in Argentina and Paraná State in Brazil. South of the San Antonio’s source near Barracão, the international border continues south along the Pepiri-Guazu River, which forms the border between Misiones Province and Santa Catarina State.

Itaipu and Rio Yguazú Reservoirs in Brazil and Paraguay

The Itaipu and Rio Yguazú Reservoirs, golden tan in color due to sediments, can be observed in the lower right quadrant of this image that spans Paraguay and southern Brazil.

The Itaipu Reservoir, on a horizontal axis along the lower right edge, was created by the Itaipu hydroelectric dam on the Paraná River, located on the border between Brazil and Paraguay.

The Rio Yguazú Reservoir, situated almost at a right angle from its horizontally flowing neighbor to the east, is located in the Alto Paraná department of Paraguay.

Alto Paraná has a combination of valleys with streams that come from the Paraná River. The lands near the banks of the Paraná River have forests, which are in trouble nowadays because of the indiscriminate deforestation. However, some reforestation programs have been enacted and replant various species of pine.

Huge Blackout in Brazil and Paraguay – November 11th, 2009

A problem with the Itaipú hydroelectric power plant plunged Paraguay and large parts of central-western and south-eastern Brazil into darkness on Tuesday night, virtually paralyzing the two countries. Experts are debating whether or not lightning and heavy winds and rains from a large atmospheric disturbance were responsibile for the blackout.

Power was being restored to Brazilian cities early Wednesday, while it was restored to Paraguay about 20 minutes after the initial loss. The power failure knocked out electricity in São Paulo, Rio de Janeiro, Brasília, Belo Horizonte and almost 800 other cities in 10 Brazilian states. It it also forced the shutdown of major airports in Rio and São Paulo, as well as the São Paulo metro system.

Itaipú, the world’s largest operational hydroelectric power plant, straddles the border between Brazil and Paraguay. Representatives of Itaipu Binacional claim that the blackout was not caused by a problem with the hydroelectic power plant itself, but by a fault in the system that transmits electricity.

Brazilian government officials, including the Minister of Mines and Energy, originally blamed the blackout on a lightening bolt and/or strong winds and rains from a large atmospheric disturbance hitting a 750 kilovolt electrical transmission line between Ivaiporã (in the state of Paraná) and Tijuco Preto (state of São Paulo).

However, the Brazilian National Meteorology Institute (INMET) stated that the sky was heavily cloudy and prone to lightening strikes only between 1:00PM and 4:00PM, during which time this image was taken, and had cleared well before the start of the blackout at 10:10PM. Here the storm is visible covering the Itaipú Dam near the triple border between Brazil, Paraguay and Argentina around 1:40PM on Tuesday.

The Paraná River, on which the dam is located, runs southward out from under the clouds, then east into the sediment-filled Rio de la Plata estuary. The cities of Buenos Aires and Montevideo can be seen on the shores nearby. Upon opening the full image, more of Brazil and Paraguay are visible to the north, above the clouds.
