Why is energy storage important in South Africa?
Energy goals Energy storage is considered crucial for South Africa’s energy goals, particularly in ensuring stable grids and integrating renewables. This is because while the country has great renewable energy sources, the problem is its load profile that does not align with the renewable energy generation profile.
Are pumped storage schemes a viable solution?
“In this context, pumped storage schemes offer a viable solution to balance supply and demand, integrate renewable energy sources and provide ancillary services to the grid,” said Van Dijk and Coetzee.
How much money does South Africa spend on solar & battery imports?
In 2023 alone, the country spent over R17.5-billion (US$905-million) on solar and battery imports. This is unnecessary because South Africa sits on reserves of manganese, vanadium, platinum and other rare earth elements. These are the critical ingredients for manufacturing clean energy systems and storage, which could be made locally.
Why is energy storage important for a sustainable electricity network?
To have a sustainable electricity network, energy storage is a crucial part of the system. While technology is likely to evolve and change in the future, there must be some sort of storage system as part of the long-term solution for the country’s energy transition.
What is behind the meter and how can it help South Africa?
While both are crucial to South Africa’s energy transition, behind-the-meter solutions provide immediate relief to the country’s energy constraints. In-front-of-the-meter projects are key to meeting actual energy transition targets and reducing emissions.
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.
