Expertise ought to profit humanity. One of the vital exceptional examples of expertise’s potential to supply enduring advantages is the Itaipu Hydroelectric Dam, an enormous binational vitality challenge between Brazil and Paraguay. Constructed on the Paraná River, which varieties a part of the border between the 2 nations, Itaipu reworked a once-contested hydroelectric useful resource right into a shared engine of financial progress.
The power plant has held many data. For many years, it was the world’s largest hydroelectric facility; the dam spans the river’s 7.9-kilometer width and reaches a top of 196 meters.Itaipu was also the first hydropower plant to generate more than 100 terawatt hours of electricity in a 12 months.
To acknowledge Itaipu’s monumental engineering achievement, on 4 March the dam was acknowledged as an IEEE Milestone throughout a ceremony in Hernandarias, Paraguay. The ceremony commemorated the challenge’s impression on engineering and vitality manufacturing.
Itaipu’s huge scale
By the late Nineteen Sixties, Brazil and Paraguay acknowledged the Paraná River’s untapped hydroelectric potential, in response to the Global Infrastructure Hub. Brazil, which was present process speedy industrialization, sought a steady, renewable energy source to scale back its dependence on fossil fuels. In the meantime, Paraguay, missing the monetary sources to assemble a gigawatt-scale hydroelectric facility independently, entered right into a treaty with Brazil in 1973. The settlement granted both countries equal ownership of the dam and its power generation.
Building started in 1975 and was accomplished in 1984, costing US $19.6 billion. The dimensions of the challenge was staggering. Engineers excavated 50 million cubic meters of earth and rock, poured 12.3 million cubic meters of concrete, and used sufficient iron and metal to assemble 380 Eiffel Towers.
Itaipu was designed for steady enlargement. It initially launched with two 700-megawatt turbine items, offering 1.4 gigawatts of capability. By 1991, the power plant reached its deliberate 12.6 GW capability. In 2006 and 2007, it was expanded to 14 GW with the addition of two extra items, for a complete of 20. Though China’s 22.5-GW Three Gorges Dam, on the Yangtze River close to the town of Yichang, surpassed Itaipu’s capability in 2012, the South American dam stays one of many world’s best hydroelectric amenities.
On common, Itaipu generates round 90 terawatt-hours of electrical energy yearly. It set a document by producing 103.1 TWh in 2016 (surpassed in 2020 by Three Gorges’ 111.8-TWh output). To place 100 TWh into perspective, an influence plant would wish to burn approximately 50 million tonnes of coal to provide the identical quantity of vitality, in response to the U.S. Energy Information Administration.
By harnessing 62,200 cubic meters of river water per second, Itaipu prevents the discharge of practically 100 million tonnes of carbon dioxide every year. Throughout its 40-year lifetime, the dam has generated greater than 3,000 TWh of electrical energy, assembly practically 90 p.c of Paraguay’s vitality wants and contributing roughly 10 p.c of Brazil’s electrical energy provide.
Itaipu’s legacy endures as a testomony to the advantages of worldwide cooperation and sustainable energy and to the ability of engineering to form the long run.
IEEE recognition for Itaipu
The IEEE Milestone commemorative plaque, now displayed within the dam’s customer heart, highlights Itaipu’s function as a world chief in hydroelectric power era. It reads:
“Itaipu energy plant development started in 1975 as a joint Brazil-Paraguay enterprise. When energy era began in 1984, Itaipu set a world document for the one largest put in hydroelectric capability (14 GW). For not less than three a long time, Itaipu produced extra electrical energy yearly than some other hydroelectric challenge. Linking power plants, substations, and transmission strains in each Brazil and Paraguay, Itaipu’s system offered dependable, inexpensive vitality to shoppers and business.”
Administered by the IEEE History Center and supported by donors, the Milestone program acknowledges excellent technical developments worldwide. The IEEE Paraguay Section sponsored the nomination.
