A fluidized-bed concentrating solar power plant comprises a particle receiver configured to contain solid state particles, wherein the particle receiver heats the solid state particles by transferring thermal energy from sunlight to the solid state particles. The plant also comprises a first silo configured to receive and store heated solid state particles from the particle receiver; a heat exchanger configured to receive the heated solid state particles from the first silo and generate a fluidized mixture comprising the heated solid state particles suspended in a gas; and a second silo configured to feed cooled solid state particles to the particle receiver, the cooled solid state particle extracted from the fluidized mixture. The first silo and the second silo each comprise a foundation comprising a base supported by a plurality of micropile units. Each micropile unit comprises a plurality of micropile columns coupled to a support block which supports the base.
