Therefore, hydropower is essential and considered as an economical factor for producing electricity. There are many untapped hydropower resources in the world. This paper is the review paper which presents about the condition of the hydroelectricity in Myanmar in detail. Hydropower is a clean energy that is a prosperous gift from nature to produce electricity. It is the power derived from continuous running water and falling water. Although it has some drawbacks to use, it cannot be denied for its advantages like abundant, reliable, low operating costs and can supply as a backup power during blackout situation and can also use as surplus energy in base load and peak load conditions in pumped storage power station.

In a hydroelectric scheme, water is stored in a dam and passed through a turbine and generator set before being released back into the river downstream. It is important to note that the power station does not consume any water in this process, it only uses the energy contained in running water to turn its turbines. Advantages : Water is a renewable source of energy. The process of electricity generation has no emissions. Disadvantages : SA is a dry country with few rivers suitable for hydroelectric plants. The construction of dams in rivers always has an impact on the environment. Micro-hydro power is a technically and economically feasible remote area power supply technology option at suitable sites.

Dams are extremely expensive to build and must be built to a very high standard. The high cost of dam construction means that they must operate for many decades to become profitable. The flooding of large areas of land means that the natural environment is destroyed. People living in villages and towns that are in the valley to be flooded, must move out. This means that they lose their farms and businesses. In some countries, people are forcibly removed so that hydro-power schemes can go ahead.

Benefits of Hydropower

News, analysis, experiments, videos, games, and educational paths on the issues of energy and the environment for complete and topical information. There are many advantages in using glacier melt waters for the production of hydroelectric power. Glaciers are a source of water that is constant and sure during the summer months, unlike the water of rivers and torrents whose capacity is subjected to remarkable variations depending on precipitation. Consequently, in the summer months, when most of the water courses on the surface suffer a lack of water, the water courses fed by the glaciers instead, are rich in this precious resource. The energy obtained from glaciers can therefore be used in the periods in which the other water resources register minimum levels and due to the melting water of the glaciers it is possible to face situations of energetic emergency such as the recent summer black-outs.


For more than a century, the technology for using falling water to create hydroelectricity has existed. The evolution of the modern hydropower turbine began in the.


Review on hydropower in Myanmar

Run-of-river hydroelectricity ROR or run-of-the-river hydroelectricity is a type of hydroelectric generation plant whereby little or no water storage is provided. Run-of-the-river power plants may have no water storage at all or a limited amount of storage, in which case the storage reservoir is referred to as pondage. A plant without pondage is subject to seasonal river flows, thus the plant will operate as an intermittent energy source. Conventional hydro uses reservoirs , which regulate water for flood control, dispatchable electrical power , and the provision of fresh water for agriculture.

Hydro power plants provide clean and affordable electricity in large quantities. They are often the main renewable energy technology choice for governments due to its ability to deliver reliable baseload energy with very minimal fluctuation. Hydro power plants are also able to accommodate changing demand and suited to large scale network response.

Hydropower, the creation of mechanical energy through the transfer of kinetic energy created by the flow of water, is currently the only large-scale renewable alternative to traditional electricity sources, such as fossil fuels [1]. As economic development spreads throughout the world, so does the demand for electricity, causing global electricity production to double in just the last two decades. Worldwide, 66 countries already generate at least half of their power from hydroelectricity, but only one third of the economically feasible potential of hydroelectric power has been realized [2]. Widespread poverty has inhibited the access to electricity in much of the developing world, additionally restricting the availability of elementary services like light and running water.

Benefits of Hydropower

Most dams in the United States were built mainly for flood control, municipal water supply, and irrigation water. Although many of these dams have hydroelectric generators, only a small number of dams were built specifically for hydropower generation. Hydropower generators do not directly emit air pollutants. However, dams, reservoirs, and the operation of hydroelectric generators can affect the environment. A dam that creates a reservoir or a dam that diverts water to a run-of-river hydropower plant may obstruct fish migration.

Hydropower has the ability to generate electricity without emitting greenhouse gasses, however, it can also cause environmental and social threats, such as damaged wildlife habitat and harmed water quality. Hydropower is the most important and widely-used renewable source of energy. Hydropower represents about 17 percent of total electricity production.


hydroelectric plants supplied as much as 40 percent of the electric energy Americans recognized the advantages of mechanical hydropower and used it.

Hydropower doesn't pollute the air like power plants that burn fossil fuels, such as coal or natural gas. Hydropower is a domestic source of energy, produced in the United States. Hydropower relies on the water cycle, which is driven by the sun, thus it's a renewable power source.
