Standard Bank head of Southern Africa’s oil and gas coverage Paul Eardley-Taylor has suggested that South Africa needs 13 GW of gas-to-power (GtP) capacity, rather than the 7.2 GW to 8.6 GW outlined in the draft Integrated Resource Plan 2023. Speaking at mine ventilation solutions developer Howden’s Technology Day, hosted at Mintek, in Johannesburg, on April 17, he explained that this calculation was made by considering the need to overcome Stage 6 or even Stage 7 loadshedding, when Stage 6 was being regularly achieved, as well as ensure a 15% reserve margin for winter peak demand.
Johannesburg Water has showcased some of the various reservoirs and systems that supply the City of Johannesburg with water. The water utility also outlined the challenges in operating the systems that feed the economic hub with the critical resource. Natasha Odendaal has the story.
Volkswagen Group Africa (VWA) last week suffered four power outages at its Kariega plant, says VWA MD and chairperson Martina Biene. This happened while there was no loadshedding scheduled for the Eastern Cape.
The National Energy Regulator of South Africa (Nersa) has initiated consultations on Eskom’s latest Regulatory Clearing Account (RCA) application for the 2022/23 financial year, where Eskom is requesting R9-million, its lowest RCA application since the utility began making yearly submissions under the claw-back mechanism. Given that the amount is less than 2% of Eskom’s allowable revenue for the year, Nersa is not required to undertake public hearings. Nevertheless, a consultation document has been published, with virtual hearings scheduled for August 2 and 4 and a decision expected by December 2.
The National Energy Regulator of South Africa (Nersa) has belatedly moved to quell concern that its recent approval of a new loadshedding code of practice, which increases the number of potential stages from eight to 16, represented a signal that the prospect for higher levels of loadshedding was imminent. Following extensive public consultations undertaken by the National Rationalised Specifications (NRS) Association of South Africa, the third edition of the NRS048-9 standard was approved by the regulator for use by Eskom and municipal system operators during times of electricity constraint.
Technology company ABB has joined investors EDP, ESB, TotalEnergies, Act and DublinBIC in becoming an investor in energy management solutions company GridBeyond, which uses artificial intelligence (AI) and data science to enable customers to improve distributed energy resources and industrial loads. The investment was made through ABB’s Technology Ventures unit.
South Africa has fallen to sixty-ninth from sixty-fourth on the World Energy Council’s (WEC’s) latest World Energy Trilemma Index which ranks more than 100 countries against the three key dimensions of energy security, equity, and environmental sustainability. The index is included in the ‘World Energy Trilemma 2024’ report, released on April 16, and which is topped by Denmark and Sweden, with Niger and the Democratic Republic of Congo at the bottom of the standings.
South Africa’s State-owned power utility Eskom said it’s in talks with government ministries over private and foreign options to fund a R390-billion expansion of its transmission network as more renewable generation comes online. Eskom supplies more than 80% of electricity to the continent’s most industrialised nation and has failed to meet demand, resulting in blackouts that have crippled the economy. The utility also owns, manages and maintains the transmission system and plans to build 14 218 kilometers of power lines over the next decade, more than three times what it has installed over the past 10 years.
Engineering News editor Terence Creamer discusses the halt in loadshedding over recent weeks; what South Africans should expect for the higher-demand winter period; and the longer-term outlook for South Africa’s electricity sector.
Selecting a generator set with a standby power rating might have been sufficient ten to 15 years ago but is no longer a viable option to cope with the current severity of local power disruptions owing to South Africa’s energy crisis, says generator manufacturer WEG Africa senior gensets manager Craig Bouwer. WEG Africa operates a generator manufacturing facility in Cape Town, which supplies standard off-the-shelf generator sets as well as custom-built, application-specific units, with capacities ranging from 10 kVA to 3 350 kVA at 50 Hz.
