South Africa’s National Nuclear Regulator (NNR) has reported that the country’s (and Africa’s) only operating nuclear power plant (NPP), at Koeberg near Cape Town, had for the past decade complied consistently with regulations concerning occupational exposure and public doses of radiation. The NNR was created in 1999 and exists to protect people, property and the environment from nuclear damage. It does so through the establishment of regulatory practices and safety standards optimised for South Africa, and through oversight and assurance activities. Koeberg is owned and operated by the country’s national State-owned electricity utility, Eskom. It is composed of two reactors, known simply as Units 1 and 2. Unit 1 entered operation in 1984 and Unit 2 in 1985. Each unit has a net generating capacity of 930 MWe. The NPP’s current licensing term will expire on July 21, 2024.
Eskom instituted its first round of load-shedding this week after a short period of reprieve. Engineering News Editor Terence Creamer joins me to discuss the causes of the latest cuts and the prognosis for 2022.
Eskom reported a material improvement in the performance of its power stations on Friday morning and indicated that it would review, by 17:00, whether it was necessary for it to sustained load-shedding over the weekend. CEO Andre de Ruyter reported that total unplanned losses had reduced to 11 258 MW, from above 14 000 MW when six-days of Stage 2 load-shedding was declared on Wednesday February 2.
A combination of renewables, storage and flexible gas are needed to create a stable and resilient energy system that provides a reliable source of electricity while transitioning away from carbon-intensive coal-fired power, marine and energy technology company Wärtsilä Energy Europe and Africa VP Kenneth Engblom has told Engineering News. “Making such smart strategy decisions will lead to more resilient electricity systems and save billions of dollars in the process,” he said in a February 3 interview.
Biomass fuel manufacturer and distributor Calore Sustainability Energy (CSE) Biomass, a division of clean energy provider Earth & Wire, started the new year with installations at two agriculture companies in Worcester, in the Western Cape. The first installation includes two 350 kW hot-air generators, installed last month, and the second installation a 2 200 kW wood chip-fuelled boiler system, to be installed in April.
The regulatory environment for environmental policies and decreasing emissions is a key driver when a boiler owner decides to convert to using natural gas as a fuel source, says natural gas supplier Egoli Gas MD Vishal Pooran. “Natural gas-fuelled boiler studies have shown an overwhelmingly positive reaction from customers when using natural gas.”
The chairperson of the South African Wind Energy Association (SAWEA) says the industry is well placed to take advantage of both the 100 MW reform and recent moves to release 36 000 ha of Eskom land in the grid-rich Mpumalanga province to accelerate renewables investments and facilitate a just energy transition from coal. Mercia Grimbeek tells Engineering News that resource measurement campaigns have overturned earlier assessments suggestive of deficient wind resources in the region to show that “a sufficient resource exists in the province for the deployment of wind energy facilities”.
Eskom cut power supply to certain parts of Dlamini in Soweto on Friday after residents allegedly denied them access to the area to install prepaid split meters. Eskom’s senior operations and maintenance manager Mashangu Xivambu said this happened despite the power utility engaging with community leaders and residents about the implementation of the project ahead of time.
President Cyril Ramaphosa was told to cut bureaucracy and focus on fixing the country’s energy crisis if he wants to revive Africa’s most industrialized economy. Water, transport and port services must be “dramatically improved,” the Presidential Economic Advisory Council (PEAC) said in a briefing note submitted to Ramaphosa ahead of his State of The Nation address next month and seen by Bloomberg. Two additional bidding rounds for the provision of renewable energy should be held this year, it said.
Electro-mechanical services and repairs company Marthinusen & Coutts (M&C) performed a significant rewind in 2020 after being contracted by German original-equipment manufacturer (OEM) Voith Hydro to wind the stator of Unit 1 at State-owned power utility Eskom’s Drakensburg hydro pump storage power station near Bergville in KwaZulu-Natal. The massive stator winding contract, which was performed by a winding team from M&C under the supervision of Voith, was the final stage in the refurbishment of three of the station’s four 250 MW motor-generator units. Eskom engaged Voith to refurbish Unit 1.
