The environmental impact of reservoirs comes under ever-increasing scrutiny as the global demand for water and energy increases and the number and size of reservoirs increases. Dams and reservoirs can be used to supply drinking water , generate hydroelectric power , increase the water supply for irrigation , provide recreational opportunities ...
These impacts can be split into operational impacts (fuel sourcing, global atmospheric and localized pollution) and construction impacts (manufacturing, installation, decommissioning, and disposal). All forms of electricity generation have some form of environmental impact, [ 1 ] but coal-fired power is the dirtiest.
The dams and their hydroelectric power plants have had positive and negative impacts on the environment. One of the most useful features of hydroelectric power plants is that generation can be quickly ramped up and down, to meet demand and balance wind and solar.
In recent years the production from the Valco plant has declined allowing capacity at Akosombo to be used to service growing domestic demand. [17] Initially, the dam's power production capabilities greatly exceeded actual demand; while the demand since the dam's inception has resulted in the doubling of hydropower production. [18]
A run-of-river plant may still produce a large amount of electricity, such as the Chief Joseph Dam on the Columbia River in the United States. [91] However many run-of-the-river hydro power plants are micro hydro or pico hydro plants. Much hydropower is flexible, thus complementing wind and solar, as it not intermittent. [92]
The hydropower plant is planned to have an installed capacity of 2,115 megawatts. [38] If completed on time in 2022, this would be Africa's 2 largest dam by installed capacity, after Ethiopia GERD Dam 5100 megawatts, over Egypt's Aswan High Dam (2100 megawatts), Mozambique's Cahora Bassa Dam (2075 megawatts), and Angola's Lauca Dam (2070 ...
Batang Toru hydropower plant is developed by PT North Sumatra Hydro Energy (PT NSHE), [1] a company founded in 2008. The pre-construction phase of the power plant has been started after the Purchasing Power Agreement (PPA) contract with the National Electricity Company (PLN) was signed on December 21, 2015.
Energy development is the field of activities focused on obtaining sources of energy from natural resources. [citation needed] These activities include the production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reuse of energy that would otherwise be wasted.
