Will Solar PV Kill Concentrating Solar Thermal Power?

The boon of concentrating solar thermal power plants is their ability to deliver more consistent electricity, and to offer thermal storage (cheaper than batteries) to expand their daily coverage. 

But it might be in serious trouble. And this time the culprit is not cheap natural gas, the Koch Brothers, nor the desert tortoise advocates.

…The relentless price declines of PV panels allows developers to build PV plants at a lower cost than their [concentrating solar thermal] CST cousins. This issue is illustrated in the following Capital Cost per watt chart (an excerpt from the upcoming GTM Research “CSP Report”). In 2010, the price to build a CSP park run by Troughs, Power Towers or Dish-Engines will cost between $5.00 and $6.55 per watt (AC). On the other hand, utility-scale PV projects can limbo below $3.50 a watt (DC).
