Largest Hydroelectric Power Plants of the World

November 22nd, 2011

Hydroelectric power plants which use potential energy of water for generation of electricity are one of the most important sources of power production on large scale basis. The construction required huge infrastructure. Some large-scale structures of hydroelectric power plants have been developed all over the world, being considered as one of the wonders of the world.

 

Itaipu hydroelectric power plant

Itaipu hydroelectric power plant is constructed on the Parana River in the areas adjoining the borders of Brazil and Paraguay. The construction began in 1975 and finished in 1991. There are 20 power generation units with total capacity of 14000 MW or 14GW. In 1995, the plant was responsible for 25% of total power supply in Brazil, and almost 80% in Paraguay.

 

The dam is unbelievably 196 meters high.

 

 

Boguchanskaya hydroelectric power plant

The construction of Boguchanskaya hydroelectric power plant on Angara River began in 1980. However, all preparatory work began in 1974. The plant has an installed capacity of 3,000 megawatts, generating 17.6 billion kilowatt hours annually.

Churchill Falls power plant

Churchill Falls power plant is the second largest hydroelectric plant in North America with an installed capacity of 5,428 MW. The powerhouse is 972 ft long and 154 ft high from the bottom to the top.

 

Churchill Falls power plant is the second largest hydroelectric plant in North America.

 

Guri hydroelectric power plant

Guri hydroelectric power plant is constructed on the Caroni River in Venezuela. The plant has 20 generation units with a total capacity of 10000 MW.

 

The dam is 1300 meters long and 162 m high.

 

 

Tucurui hydroelectric power plant

Tucurui hydroelectric power plant is located on the Tocantins River. It has 23 generators with total generating capacity of 8370 MW. The plant is the largest 100% Brazilian plant.

 

The Tucuruí Hydroelectric Plant is one of the biggest engineering works in the world.

 

Sayano-Shushenskaya hydroelectric power station

Sayano-Shushenskaya hydroelectric power station is located on the Yenisei River, near Sayanogorsk in Khakassia, Russia. It is the sixth largest hydroelectric plant in the world. Its total installed capacity and average annual production are 6,400 MW and 23.5 TWh respectively.

 

The station’s constructions include the dam, a power plant building, and an additional spillway.

 

Bratsk hydroelectric power plant

Bratsk hydroelectric power plant, which is developed on Angara River, produces 22.6TWh of power annually. Its total power generation capacity is 4500MW. The plant has 18 power generation units, each of which is equipped with Francis turbine and produces 250MW. There is a long penstock of 5140 meters from reservoir of the dam to power generation units.

 

There are costal concrete wall which are 506 meters long

 

 

Krasnoyarsk hydroelectric power plant

Krasnoyarsk hydroelectric power plant with power generation capacity of 6000MW is constructed on Yenisey River. The dam is 119 meters high. The work on this plant was completed in 1964; however, it has brought many changes in the climate of the surrounding areas.

Utilizing Hydroelectric Energy

November 3rd, 2011

In our quest for becoming a greener Earth, one of the best solutions is the continued usage and utilization of hydroelectric energy. Hydroelectric energy is created by utilizing the gravitational force of falling or flowing water. This process is quite reminiscent of the way that wind energy is created. Most people don’t know, but roughly 7% of the utilized power in the United States is created using hydroelectric energy.

One common procedure to do so is by damming up water flowing in a river behind a large concrete wall. This water holds a large amount of potential energy. As it falls from the dam, it flows through a turbine with rotary blades. Electromagnets spin within the turbine as the water flows through it and a current is created. The energy is transferred to coils. These coils take the current to a transformer and the voltage is multiplied for transmission to homes and businesses through power lines.

This rather elegant method of creating energy without drilling for coal or burning fossil fuels enables us to benefit from a natural resource to create hydroelectric energy.

This energy source not only does not pollute the Earth’s atmosphere but also reduces green house gasses, and consequently, the threat of global warming. Better yet, this energy is virtually limitless, as the water from streams and rivers is provided by rain fall and is naturally replenished.

Other advantages of this energy are that water is also a generally an available resource in many countries and eliminates the cost of the fuel used for this power source. Once hydroelectric power plants are built on waterways they are relatively inexpensive to operate. As the technology continues to mature, it is likely that power resource will become even more efficient and widespread.

Regardless of the source of electricity, whether it is created using wind, water, oil or coal, the benefits we gain are endless.

Currently, water provides the electricity needed for homes and businesses around the world. This electricity operates everything from house hold appliances to wireless devices and large production equipment. Hydroelectric energy can also be stored to be later used in a motor vehicle to reduce our dependence on fuel.
