CSP: PV Not the Only Game in Town


With the price of photovoltaic (PV) panels plummeting and the advent of the era of PV “solar farms,” large scale solar thermal projects have not been getting much love lately, at least not in the USA. Concentrating Solar Power (CSP) is a workhorse technology for large-scale solar power generation. So why aren’t we hearing more about it?


 What is CSP? According the the Solar Energy Industry Association’s Website: “Concentrating solar power (CSP) plants use mirrors to concentrate the energy from the sun to drive traditional steam turbines or engines that create electricity. The thermal energy concentrated in a CSP plant can be stored and used to produce electricity when it is needed, day or night. Today, over 1,400 MW of CSP plants operate in the United States, and another 390 MW will be placed in service in the next year.” Built-in storage. That’s the holy grail of solar, right? Why are we not all over this?
