The Bokpoort concentrated solar plant in Northern Cape Province, South Africa, is now operational, having been built by a joint venture between Spain’s Acciona, Sener and TSK and South Africa’s Crowie.
The $300m project has been developed by ACWA Power and has a capacity of 55MW.
It began operations and makes use of SENERtrough parabolic trough collector technology with a 1,300MWh system of two storage tanks.
Using around 180 loops, the plant can produce more than 230GWh per annum. This is the fourth concentrated solar plant built by Acciona outside Spain.
In late-2014, Accion’s Sishen photovoltaic plant began operations. Its Gouda windfarm came online in August 2015, with a capacity of 138MW.
Sener and Acciona are presently developing a 100MW solar complex at Kathu for GDF Suez.
Along with Kathu and Bokpoort, Sener has a third thermosolar facility in South Africa.
In these three projects, Sener supplied key technology such as the SENERtrough parabolic trough collectors and the molten salt storage system that enables the plants to continue to produce electricity in the absence of solar radiation.
Sener has so far completed 29 solar plants, which have been turnkey projects in Spain, the US, South Africa, and Morocco with a total capacity of more than 2,000MWe.
