Bethlehem Hydro
Bethlehem Hydro owns and operates two small hydro power plants situated in the Dihlabeng Local Municipality (Thabo Mofutsanyana District Municipality) in the Free State province of South Africa. The scheme utilizes the water supplied to South Africa by the Lesotho Highlands Water Project, which releases water into the As River via a tunnel outlet near the town of Clarens. South Africa has limited potential for hydro energy due to low average annual rainfall making projects like Bethlehem Hydro rare. The project was identified in 1999 and developed by NuPlanet Project Development. The two power stations in the scheme will cut back carbon dioxide emissions by 33,000 tons per year by reducing the demand for traditional fossil-fuel power stations. Sol Plaatje Power Station The Sol Plaatje Power Station was the first commercial small hydro power station constructed in South Africa for 22 years. It was commissioned in November 2009 and is located close to Bethlehem, Free State. The pow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lesotho Highlands Water Project
The Lesotho Highlands Water Project (LHWP) is an ongoing water supply project with a hydropower component, developed in partnership between the governments of Lesotho and South Africa. It comprises a system of several large dams and tunnels throughout Lesotho and delivers water to the Vaal River System in South Africa. In Lesotho, it involves the rivers Malibamatso, Matsoku, Senqunyane, and Senqu. It is Africa's largest water transfer scheme. The purpose of the project is to provide Lesotho with a source of revenue in exchange for the provision of water to South Africa, as well as generate hydroelectricity for Lesotho. As of 2015, royalties paid by South Africa to the Lesotho government amount to R780 million (approximately €50 million), equivalent to about 5% of Lesotho’s state income outside of taxes. The hydro-electric power has enabled Lesotho to become self-sufficient in electricity production, however criticisms have included loss of livelihoods for displaced peopl ...

As River
The As River is a tributary of the Liebenbergsvlei River in the eastern Free State, South Africa. Since 1968 it is impounded by the Sol Plaatje Dam (formerly: Saulspoort Dam) at its confluence with the latter river, just east of Bethlehem. Its origin is some 35 km southeast of Bethlehem, on the northern slopes of the Rooiberge, near Clarens. With the opening of the northern delivery tunnel of the Lesotho Highlands Water Project in 1998, the once tiny stream was transformed to a strong-flowing river. Water delivery The As River is one of the discharge points for the Lesotho Highlands Water Project. As of 2004, 18 cubic meters of water was released per second, and the river's flow is consequently not seasonally variable. The Stortemelk Dam, situated downstream of the outfall, was one measure taken by the then Department of Water Affairs, to stabilize water flow and limit erosion. By 2004, four weirs had been built.

Clarens, Free State
Clarens is a small town situated in the foothills of the Maluti Mountains in the Free State province of South Africa and nicknamed the "Jewel of the Eastern Free State". It was established in 1912 and named after the town of Clarens in Switzerland where exiled Paul Kruger spent his last days. It is situated 336 km from Johannesburg, 284 km from Bloemfontein, 389 km from Durban. History A farm called "Leliehoek" (English: Lily Corner) was bought from Hermanus Steyn in 1910, and in 1911 Piet de Villiers sold his farm "Naauwpoort" (situated near the Titanic rock) to a company wanting to establish a village there. These two farms were divided into erven and sold for fifty pounds each. A commission was appointed in 1912 to finalize negotiations, and a decision was made to name the village "Clarens" in honour of President Paul Kruger’s influence in the area. This came about in the following way - during the Free State-Basotho War of 1865 - 1866, five "burgers" fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydro Energy
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Greenhouse Gas Emissions
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely follow ...

Fossil-fuel Power Station
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator. The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine. All plants use the energy extracted from the expansion of a hot gas, either steam or combustion gases. Although different energy conversion methods exist, all thermal power station conversion methods have their efficiency limited by the Carnot efficiency and therefore produce waste heat. Fossil fuel power stations provide most of the electrical energy used in the world. Some fossil-fired power stations are designed for continuous operation as baseload power plants, while others are used as peaker plants. However, starting from the 2010s, in many countries plants designed for baseload supply are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kaplan Turbine
The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan, who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low- head applications which was not possible with Francis turbines. The head ranges from and the output ranges from 5 to 200 MW. Runner diameters are between . Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as 54.5 rpm ( Albeni Falls Dam) to 450 rpm. Kaplan turbines are now widely used throughout the world in high-flow, low-head power production. Development Viktor Kaplan, living in Brünn, Austria-Hungary (now Brno, Czechia), obtained his first patent for an adjustable blade propeller turbine in 1912 ...
