Eltherm South Africa has been awarded the contract to provide the design and installation of the electrical heat tracing (EHT) system for the 100 MW Kathu Solar Park. The Kathu Concentrated Solar Power (CSP) Park will be built in the Northern Cape.

Eltherm to provide EHT for Kathu Solar ParkThe contract was awarded to Eltherm by a consortium comprising of ACCIONA, ENGIE South Africa and SENER Engineering and Construction. Eltherm will deliver EHT to the solar park’s Thermal Energy Storage (TES), Heat Transfer Fluid (HTF) and balance of the plant. The TES, which features the plant’s molten salt storage will be the main focus of the EHT installation, with temperature classes of T1 – T3 being maintained.

EHT is required in CSP plants to maintain temperatures and prevent heat losses. EHT pre-heats empty pipes and equipment to maintain the right temperature throughout the process and to avoid solidification of the fluids. It also compensates for the loss of heat when fluids flow to pipes with a lower ambient temperature.

The Kathu Solar Park’s EHT system will be managed by Eltherm’s TraceVision software and controllers in order to ensure efficient and uninterrupted operations at the plant. It is estimated that the plant’s parabolic trough technology will provide up to five-hour TES storage capacity to meet peak energy demand after sunset.

Eltherm has installed EHT systems at a number of other solar plants, including Xina Solar One in Pofadder, in the Northern Cape. The company is currently involved with the maintenance and repairs of the heat tracing systems at Kaxu Solar One and Bokpoort CSP, also in the Northern Cape. Globally, Eltherm was responsible for the heat tracing at the Noor Ouarzazate Solar Complex in Morocco, as well as Ashalim Power Station in Israel, among others.

“The Kathu Solar Park contract undoubtedly reconfirms our strength in the South African CSP marketplace. We’re extremely excited to form part of Eltherm’s significant growth phase and leadership in this important global market segment. EHT plays an important role in the successful running of CSP plants and ultimately contributes to the world’s strides towards renewable energy provision,” says Peter Stone, Managing Director at Eltherm South Africa.
