BrightSource Adds Storage to Its Solar Thermal PPAs With SCE: A common refrain about the limitations of solar

A common refrain about the limitations of solar power is that the technology only works when the sun is shining. That's certainly true of photovoltaic (PV) solar technology. Some consider the variable nature of PV (or wind power) a threat to the reliable operation of the electrical grid . Concentrating solar power (CSP), while more expensive upfront than PV technology, has an absolute advantage over PV: the ability to store thermal energy long after the sun goes down. This ability improves CSP's capacity factor and dispatchability, and has the potential to improve CSP's levelized cost of energy (LCOE). And CSP needs every advantage it can muster, given the plunging cost of PV and the exploding scale of the global photovoltaic market. In fact, a significant number of planned CSP plants have switched to PV because of the challenging economics of CSP, as well as financiers' f...
