Progress in the construction of the Ilanga-1 plant

As a member of the EPC consortium, SENER is participating in the turnkey construction of the Ilanga-1 solar thermal plant in South Africa, where it is responsible for the engineering, procurement management, construction and commissioning. It is also participating in the O&M (Operation and Maintenance) consortium that will operate and maintain the plant once it is in operation. SENER is also a minority shareholder in the company that owns the project, ‘Karoshoek Solar One (RF) Proprietary Limited’, whose other partners include COBRA and local investors.

It is a 100 MW plant with parabolic trough technology SENERtrough® designed and patented by SENER with a thermal energy storage capacity of 5 hours thanks to the use of molten salts. The plant is located near the town of Upington in the Northern Cape province, and once operational it will be able to supply electricity to more than 80,000 homes.

The construction work started on the plant in October 2015 and commissioning phase is scheduled for November 2018. The works are currently progressing as planned and the 266 loops and components of the solar park are already being manufactured, most of them in local workshops. One of the project’s biggest challenges is meeting the demanding commitment of using locally manufactured products.

Ilanga-1 is SENER’s third CSP project in South Africa, after the Bokpoort plant (50 MW), commissioned in March 2016 and owned by ACWA Power, and the Kathu Solar Park (100 MW), which is currently under construction and is owned by ENGIE. They are all turnkey projects that use SENERtrough® technology and molten salt thermal energy storage systems.
