Tallest solar tower in the world

November 2nd, 2017, Published in Articles: Energize

GE, BrightSource Energy and Megalim Solar Power has installed the solar receiver steam generator at the 121 MW Ashalim Solar Thermal Power Station in Israel’s Negev desert. With the receiver in place, the 250 m tower is now the tallest power tower in the world. When Ashalim is operational, 50 600 software-controlled mirrors, spread over 3,15 km2, will track and reflect sunlight onto the receiver on the tower, which will heat water to create superheated steam. The steam will drive a conventional steam turbine to generate electricity.

The project will avoid 110 000 t of CO2 emissions while producing enough electricity to support the equivalent of 120 000 homes during the daylight hours in which the plant will operate. The lift was a first-of-its-kind due to the sheer density of the receiver, as well as the need to maintain very tight tolerances throughout the duration of the lift.
