What is peak-load shifting?
Peak-load shifting is the process of advancing or delaying large energy load blocks to minimize generation capacity requirements and regulate load flow in the power supply system. This is known as peak-load shifting.
How can South Africa cope with high energy demand?
South Africa is exploring various new ways of easing the strain on the national grid during periods of high energy demand. It is part of government’s commitment to tap into all available avenues to help get us through our energy crunch.
How much energy did South Africa need in Q1 2023?
In total, South Africa experienced a shortage in energy supply of 5 751GWh in Q1 2023, which was more than the combined load shedding in the first three quarters of 2022. As a proportion of energy demand over the period, load shedding equated to 10.2% of the 55 983GWh of energy that Eskom did supply in Q1.
Does South Africa have pumped electricity?
“It offers reliable, flexible, and low-carbon electricity,” wrote Van Dijk. Currently, South Africa has four major pumped storage schemes: the Drakensberg, Palmiet, Ingula and Steenbras. These facilities help stabilise the grid by storing surplus energy during low demand and releasing it during peak periods.
What is Phase 1 of Eskom's battery energy storage system project?
Phase 1 of Eskom’s Battery Energy Storage System project also includes the installation of 833 MWh storage capacity at eight substation sites in KwaZulu-Natal, Eastern Cape, Western Cape and Northern Cape. This phase also includes about 2 MW of solar PV capacity.
What is local energy storage?
Local energy storage is a technology that can mitigate fluctuations in output power by regulating ramp-up controls and absorbing spikes in power. It responds to sudden sags by injecting power, smoothing the generation curve and providing a more stable power source and reliable distribution grid.
