Abstract

A method for modifying a solar thermal power plant operating on conventional oil based technology into a hybrid solar thermal power plant includes: providing an oil-based solar thermal power plant, which includes a solar collection system with at least one radiation absorber tube containing a heat transfer oil to be heated by the solar collection system; providing a molten salts solar thermal power plant, which includes a solar collection system to heat a molten salts mixture; and coupling the respective plants such that the hybrid solar thermal power plant is configured to heat medium temperature steam generated by the oil based solar power plant by the molten salts mixture thereby producing high temperature steam and subsequently supplying it to a steam turbine to generate electricity.
