The Khi Solar One Power Station is located in Raaswater, South Africa. The solar tower power plant has been in operation since 2016 and has a nominal output of approximately 50 megawatts. In this TanDEM-X image, the circle of solar mirrors appears strikingly radiant. The 2120 heliostats are aligned with the Sun and reflect the radar beams at an almost identical angle, making them appear very bright. Using its 'staring spotlight' mode, the satellite observed an area of 3.9 by 4.8 kilometres with a resolution of 74 by 30 centimetres (range direction by azimuth/flight direction).
