Gemasolar – Solar Power 24/7
June 24, 2011
It used to be that the United States lead the world in technology. Most of the technologies powering the new energy revolution were born here, but are being perfected elsewhere.
Gemasolar is a 19.9-MW plant with a 15-hour ‘battery’. Gemasolar’s expected production is 110,000 MWh per year—or about enough to fully power 25,000 households. Gemasolar to produce electricity about 6,400 hours per year – a capacity factor of 75%. Gemasolar’s power tower has a height of 140 meters (459.3 feet.)
The receiver on top of the tower is like a radiator that is heated to a temperature of about 565 degrees Celsius (1,050 degrees Farenheit) by the sunlight reflected by 2,650 heliostats with a total reflective surface of about 300,000 square meters (3.32 million square feet.)
