Power station harnesses Sun's rays

1. The solar tower is 115m (377ft) tall and surrounded by 600 steel reflectors (heliostats). They track the sun and direct its rays to a heat exchanger (receiver) at the top of the tower
2. The receiver converts concentrated solar energy from the heliostats into steam
3. Steam is stored in tanks and used to drive turbines that, eventually, will produce enough electricity for up to 6,000 homes
