Mineral Resources and Energy Minister Gwede Mantashe finally ended a destructive near seven-year disruption to the procurement of renewable energy in South Africa, when he announced the names of 25 wind and solar preferred bidders on Thursday night. The bidders are expected to build 2 583 MW of new generating assets, and introduce these into the country’s power-stressed grid within the coming 36 months.
A free smart device app and Web-based tool has been developed to enable anyone in South Africa to measure how much energy, cost and greenhouse-gas emissions savings will be achieved by switching to light-emitting diode (LED) lighting, while ensuring the quality of luminescence is maintained or improved. A team from State-owned South African National Energy Development Institute (Sanedi), supported by German development agency GIZ and the South African German Energy Partnership, investigated three public sites in South Africa used by government agencies or departments using the app, and each site demonstrated significant savings in energy and costs, as well as rapid payback periods of up to two years, Sanedi Renewable Energy Centre of Research and Development manager Dr Karen Surridge said on October 28.
The National Energy Regulator of South Africa (Nersa) has notified the Gauteng division of the High Court that it will oppose Eskom’s application to have the regulator’s decision to reject the utility’s fifth multiyear price determination (MYPD5) revenue application reviewed and set aside. Eskom approached the court on October 15 after the regulator voted, on September 30, to reject Eskom’s MYPD5 submission for the three financial years from 2022/23 to 2024/25.
As a potential means to transition away from fossil-fuel-based electricity generation methods and towards greater decarbonisation of its energy mix, independent system modeler Clyde Mallinson this week said South Africa needs to build energy storage solutions to bridge the gap between when renewable energy is produced and when it is not to meet daily and peak demand.
Speaking during a webinar on the system benefits of energy storage on October 27, he said South Africa’s peak hourly electricity demand was 34.1 GW, while its average hourly demand was 26.4 GW.
The United Nations climate talks haven’t even started and host-nation UK is already conceding that a key goal – a deal to end coal burning – is off the table.
“It will be hard to consign coal to history at Glasgow,” Barbara Woodward, the UK’s ambassador to the UN, said in an interview Wednesday, a day before she travels to Scotland for the COP26 climate conference that begins Sunday. “We’ve got to give up coal and some of the plans do not foresee that.”
The City of Johannesburg (CoJ) this week unveiled a new plan to accelerate security of reliable power supply for residents and businesses in the municipality. Headed by executive mayor Mpho Moerane, the CoJ has launched an energy mix Energy Sustainability Strategy for the municipality, through which the city seeks to increase its capacity to cater for its growing developmental needs.
