Pondage usually refers to the comparably small water storage behind the weir of a run-of-the-river hydroelectric power plant. Such a power plant has considerably less storage than the reservoirs of large dams and conventional hydroelectric stations which can store water for long periods such as a dry season or year.
Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power or water energy, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. [1] Hydropower is a method of sustainable energy ...
Nepal Electricity Authority (NEA) has established an autonomous company named Upper Tamakoshi Hydropower Limited (UTKHPL) in March 2007 (2063/11/25 B.S.) as an executing agency for the implementation of the Project. There are six full-time and two invitee members in the Board of Directors (BoD) at present.
For example, a low-head hydro power plant with hydrostatic head of few meters to few tens of meters can be classified either as an SHP or an LHP. [30] The other distinction between SHP and LHP is the degree of the water flow regulation: a typical SHP primarily uses the natural water discharge with very little regulation in comparison to an LHP.
Three Gorges Dam (left), Gezhouba Dam (right). This article provides a list of the largest hydroelectric power stations by generating capacity. Only plants with capacity larger than 3,000 MW are listed.
The United States used more hydropower than any other state at the time. [ 11 ] Recognizing that the great hydroelectric potential of the Falls exceeded the local demand for electricity, a large power company was established nonetheless at the prime location for development; it awaited the prospect of an effective long-distance power ...
Hydrostatic head is also used as a measure of the waterproofing of a fabric, commonly in clothing and equipment used for outdoor recreation.It is measured as a length (typically millimetres), representing the maximum height of a vertical column of water that could be placed on top of the fabric before water started seeping through the weave.
Feasibility calculations may be affected by seasonality. For example in Finland, capacity factor during the cold winter months is more than double compared to July. [6] While the annual average in Finland is 29.5%, [6] the high demand for heating energy correlates with the higher capacity factor during the winter.
