Not necessarily obsolete, just uncompetitive. Many of the concentrated thermal systems can meet 30% efficiency but they usually are more of steel and plumbing projects than solar projects. On top of the high initial capital cost, they have higher maintenance as it is a system of high temperatures with moving parts.

That was exactly the meaning/claim - that because PV prices have fallen, it doesn't make sense to build new thermal plants.
