Im pretty sure larger are on the drawing block, but this one is about to fully turn on.
I listened to a presentation comparing the merits of solar thermal vs solar pv, and the main driver of solar thermal was cheap energy storage today, and very competitive costs. Limits are that it’s only in key environments (low humidity, high sunlight). And that thermal projects seem to have to stay above 50MW to compete financially.
This plant offsets 760,000 tons of CO2 annually.
The plant is called the Noor Complex, and is the world’s largest concentrated solar power (CSP) plant. It is being constructed at the site near the city of Ouarzazate which is on the edge of the Sahara Desert. It was first powered in February 2016, officially turned on by His Majesty Mohammed VI of Morocco. Currently it is powering 160 megawatts against an intended target of 580 megawatts.
