Energy From Hydro Power

Hydropower or hydro energy is the energy produced by the movement of running or falling water. If the kinetic energy in running water can be exploited, it can be used as a renewable and even sustainable energy source to generate electricity or power other equipment. Hydropower is simply the conversion of the kinetic energy of water into electrical or mechanical energy. The extracted energy is obtained due to the movement and velocity of free-flowing or falling water, and their kinetic energy can be stored as potential energy by creating a barrier in front of rivers, especially fast-flowing rivers. Even waterfalls, due to their relatively high altitude and the wind, have huge sources of hydropower that need to be extracted with sufficient knowledge and equipment.

Using Hydro Power

The use of hydropower as a renewable energy source has been common since ancient times for irrigation or work with mechanical devices such as water mills, textile mills, home and local elevators. At present, with the advancement of technical knowledge and equipment for hydropower extraction, this energy can be considered an attractive alternative to fossil fuels because it has no direct role in the production of air and environmental pollutants.

International institutions such as the World Bank see hydropower as a low-carbon energy source (carbon footprint and pollution are low and not noticeable unlike fossil fuels) for the economic development of countries with high potential for water extraction. In short, hydropower is a reliable source of energy and is cost-effective. Large hydropower plants can produce hundreds of megawatts of electricity, and smaller plants can generate less than 10 megawatts of electricity.

There are also smaller power plants called Micro and Pico, which produce between 50 watts and 500 kilowatts of electricity. The lifespan of such power plants is more than 30 years. Micro-hydro power plants are so-called power plants that have a production capacity of 100 kW.

These power plants can power an independent home or a small community, and may occasionally be connected to power grids. On the other hand, Pico hydroelectric power plant is used to generate electricity below 5 kilowatts and even 800 watts. Small 200- or 300-watt turbines can power grid-independent homes in a developing country with just one meter of water falling.

The benefits and advantages of extracting electricity from water can be summarized as follows:

Hydropower extraction technology can also be used in developing countries.
Compared to other energy sources, hydropower has fewer environmental effects.
Electricity extraction technology is relatively simple and stable and provides the consumer with a lifespan of more than 30 years, and at the same time does not require a large amount of initial capital.
The final cost of such projects can ultimately outweigh the costs of other sources of energy production and be more economically viable compared to them.
Hydropower generation operations are automated and have low maintenance and operation costs.
Excluding fuel produced for energy transmission and logistics, we can say that we will not need any other fuel to generate electricity from water.
The intensity of the energy extracted will vary depending on the water in a place, but in general this energy will be available at a constant rate at all times.

The greatest application of hydropower is to generate electricity. Aware of this need, Zirsakht Tadbir Arian Company, with the help of modern knowledge and using the best equipment for extracting electrical energy from water, converts the mechanical energy of water into electricity. It is interesting to know that 15% of the world’s electricity is generated through mechanical energy from running water or water behind dams, and even in 35 countries more than 50% of their electricity needs are supplied through hydropower. In such countries, either the potential energy of the water behind the dam and with height or the kinetic energy of running water is used to supply electrical energy. Therefore, hydropower plants can be divided into two general categories:

Power plants that include a reservoir and dam. In these power plants, water is collected behind the dam in a reservoir and stores high potential energy. Eventually, water from this reservoir flows through canals and drives a water turbine to generate electricity.

Other types of power plants include running water power plants. As the name implies, in such a power plant, a barrier is built on the stream of the flowing water in order to control the flow of water as much as possible. Such a power plant requires a constant and continuous flow of running water and therefore can not provide a stable electric current unlike dams. In these power plants, the use of water's kinetic energy is the main goal in order to extract electrical energy.

Currently, only four hydropower plants with a capacity of more than 10 GW are built in the world. These include the 22,500-megawatt Three gorges Dam in China, the 14,000-megawatt Itaipo Dam in Brazil, the 13,860-megawatt Zilodo Dam in China, and the 10,200-capacity Central Hidroeléctrica Simón Bolívar Dam in Venezuela.

Zirsakht Tadbir Arian Company is one of the top companies and pioneers in the field of sustainable energy. In order to provide services to its customers, the company uses modern and high-efficiency equipment, taking into account government laws and restrictions, with the help of leading experts in the field of hydropower helps to extract the required energy from water.
