Palmiet Pumped Storage Scheme
The Palmiet Pumped Storage Scheme consists of two turbine units located upstream of the Kogelberg Dam on the Palmiet River near Cape Town, South Africa. The pumped-storage hydroelectricity plant is capable of responding to a surge in peak power demand in minutes. At night, excess power on the grid generated by conventional coal and nuclear plants is used to pump water to the upper Rockview Dam overlooking Gordon's Bay. It is regarded as a forerunner in environmental engineering. The whole Palmiet site is a conservation area and in December 1998 the area was declared a Biosphere Reserve by UNESCO - the first in South Africa.

Palmiet Pumped Storage
''Prionium serratum'', the palmiet, is a robust, evergreen, semiaquatic, rhizomatous flowering plant growing to in height. It is the only species in the genus ''Prionium'', and is endemic to South Africa (Cape Province and KwaZulu-Natal). Some authors have separated ''Prionium'' from the Thurniaceae, putting it instead in its own family, the Prioniaceae. Description The stem of ''P. serratum'' is up to in diameter and covered with the black, fibrous bases of old spirally arranged leaves, four-ranked or tristichous, as in the closely related family Juncaceae, a family in which it was previously placed - it also has close affinities with the bergpalmiet (''Tetraria thermalis'') in the Cyperaceae. The strap-like lanceolate leaves are rigid, with a high silica content, narrow, leathery, grey-green, and with toothed margins. The small, brown flowers are on a branched inflorescence about 1 m in length. Plants are hermaphroditic and pollination is anemophilous. The fruit is a dry ...

Palmiet River
Palmiet River ( af, Palmietrivier) is a river located in the Western Cape province of South Africa. The Palmiet River is a typical Western Cape river, experiencing winter rainfall and it is important for the Western Cape Water Supply System. It has a small catchment area of 500 km2, flows through the expanse of the Elgin Valley, and reaches the ocean through an estuary. This river has five irrigation and hydro-power dams along its length, and provides water for agricultural and industrial uses, as well as to the city of Cape Town. It is unclear why there has been an apparent increase in flow over the last 30 years. This river is named after the plant known as Palmiet ''(Prionium serratum)'' and should not be confused with the Palmiet River near Durban, or the Palmiet River which is a tributary of the Keurbooms River.

Pumped-storage Hydroelectricity
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gordon's Bay
Gordon's Bay ( af, Gordonsbaai) is a harbour town in the Western Cape province of South Africa. It is included in the City of Cape Town metropolitan municipality as a suburb of the Helderberg region (formerly called Hottentots Holland). It is situated on the shores of Gordon's Bay in the northeastern corner of False Bay about 58 km from Cape Town to the south of the N2 national road and is named after Robert Jacob Gordon (1743–1795), the Dutch explorer of Scottish descent. Gordon's Bay is the smallest of three towns in the Helderberg region ( Somerset West, Strand and Gordon's Bay), so named after the Helderberg Mountain which is part of the Hottentots-Holland Mountains which border the locality on two sides. Gordon's Bay was originally named "Fish Hoek", many years before the town of the same name, located on the western side of False Bay, was founded. Evidence of this can be seen on the outside wall of the local Post Office. Gordon's Bay consists of the old vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
