The best available techniques (BATs) are used now widely in the different industries. The paper contains the description of some new technologies, or BATs, intended for the concentrating solar plants (CSPs) and installations. The most part of these BATs presented in article were suggested in ENIN. But together with them, there are some foreign prospective technologies or BATs. Some BATs were suggested both in ENIN and abroad, and they include the hybrid plants, the usage of thermal accumulators and the application of effective high-temperature heat carriers. The differences between different approaches in Russia and abroad are shown. All of them have a goal to increase the CSP efficiency. Some BATs were developed a certain time ago, but some were developed during the operation of existing large and small CSP. The niche of using different plants determines the placement and sphere of applications of these small and large plants with concentrators. A progress in creating the tower CSPs as well as the installations with parabolic troughs (PT) and Fresnel lens is shown. The one-loop and two-loop CSPs are compared, and the advantages and problems of one-loop plants are shown. The recommendations for future works and investigations are given and they include not only BATs but also the solution of such problems and indicators as financial support, economic indices, education and even safety measures.
