"For one, the cost, though lower, is still $7.3 billion per gigawatt. Second, the area required is mind-boggling with a total of 1.1 million square meters of solar collectors. Finally, the heat storage capacity of this system is just 7.5 hours, meaning it can only operate around 4,000 hours per year, vs 6,000 for the solar tower design of Gemasolar (and 2,000 hours for traditional solar technology)."
As always, these analysis of power production are based on centralized generation and distributed (grid) delivery. Solar PV is best used where it is generated and best stored where it is generated. This is why NRG Energy is looking at the lease of solar PV installations on homes and businesses with perhaps battery storage and a natural gas backup generator. NRG is looking at a distributed solution instead of whining about solar PV installations not paying "their fair share", as the all encompassing excuse to raise rates.
