One of the key features of concentrated solar power (CSP) technology is the potential to operate with storage and provide a truly dispatchable renewable energy supply.

With energy stability and supply a critical issue for South Africa, CSP is set to play a leading role in the energy mix

South Africa’s energy supply is currently characterized by uncertainty. There is not enough power supply to meet current demand. During the winter months, the national grid can get close to the border of power failure, a situation which repeatedly threatens to destabilize business and industry, and affects foreign investment.

Renewable energies play a key role is South Africa’s energy mix. CSP is currently the only renewable technology that can store energy and dispatch at demand providing a unique advantage over other renewable energy technologies and in particular over solar PV at a time when the this one is able to deliver low LCOE values.

Thermal energy storage (TES) innovations are bringing costs down and can also help developers and EPCs meet local requirement. “One of the advantages of NEST’s storage technology is that it’s well suited for high local content, because it basically consists of concrete, steel and insulation material. The Heatcrete storage medium is made from readily available materials that typically can be sources locally”, says Jarl Pedersen, Vice President at NEST AS.

With South Africa providing one of the most exciting CSP markets worldwide, leading South African companies and institutions such as NEST AS, Stellenbosch University and Eskom will be discussing the key roles of thermal energy storage in the future of the CSP industry at CSP Today South Africa 2014 (8th – 9th April, Cape Town) and how developers and EPC contractors can meet local content requirements with TES solutions.
