South African Energy Crisis
The South African energy crisis is an ongoing period of widespread national blackouts of electricity supply. It began in the later months of 2007 and continues to the present. The South African government-owned national power utility and primary power generator, Eskom, and various parliamentarians attributed these rolling-blackouts to insufficient generation capacity. According to Eskom and government officials, the solution requires the construction of additional power stations and generators. Corruption and mismanagement of Eskom, most notably during the Jacob Zuma administration, have exacerbated this energy crisis; neglect by Eskom staff in addition to multiple acts of sabotage has also contributed to ongoing power supply problems. Background In a December 1998 report, analysts and leaders in Eskom and in the South African government predicted that Eskom would run out of electrical power reserves by 2007 unless action was taken to prevent it. To improve power supply and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electricity Regulation Act
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...

Matla Power Station
Matla Power Station in Mpumalanga, South Africa, is a coal-fired power plant operated by Eskom and consuming the output from the Matla coal mine. History Construction started in 1974, and the last unit was commissioned in July 1983. In 1981 the southernmost smokestack measuring in height was demolished after it partially collapsed during construction, killing 4 workers. It held the world record for the tallest free standing structure to be explosively demolished for 24 years until the 2006 demolition of the Westerholt Power Station chimney.

Power Station
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and an increasing use of renewables such as solar, wind, geothermal, and hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry. In 1878, a hydroelectric power station was designed and built b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kendal Power Station
Kendal Power Station is a coal-fired power station in Mpumalanga, South Africa. It is sited in a coal-mining area; one of its sources is AEMFC's coal mine at Vlakfontein, near Ogies. History Design Kendal was built between 1982 and 1993. The first unit went online in 1988. On completion in 1993 it became the world’s largest indirect dry-cooled power station. The total station water consumption of a dry-cooled system does not exceed 0,2lkWh, compared with the 2,5lkWh consumed by wet-cooled systems. Evaporation losses in wet-cooled systems account for approximately 80% of the water requirements of a conventional wet-cooled power station. Kendal is fired with coal mined in the Bombardie Cologne coalfield. Twin overland conveyors transport the coal from the mine through the stock-year into the coalbunkers. For each unit there is one cooling water system, including the cooling tower with its tuber bundle heat exchangers, three circulating pumps (units 4 to 6) two circulating ...

Kriel Power Station
Kriel Power Station in Mpumalanga, South Africa, is a coal-fired power plant operated by Eskom. It is located about 4 km from Matla Power Station just outside the town of Kriel (Emalahleni Local Municipality, Mpumalanga). In contrast with most other Eskom power stations, the turbine generators at Kriel are each housed in a separate building rather than the more common single turbine hall. When Kriel was completed in 1979 it was the largest coal-fired power station in the Southern Hemisphere. It was also one of the first stations to be supplied with coal from a fully mechanised coal mine. History On 25 July 2022, the entire power station tripped. Eskom said the first fault caused units 1, 2 and 3 of the power station to trip, while the second fault tripped units 4 and 5. Unit 6 was already offline.
