The present invention relates to a solar power plant that utilizes a working fluid to run a turbine assembly, which in turn is connected to a heating assembly and a cooling assembly to form a closed loop. The temperature and pressure gradient is achieved by employing specially designed heating and cooling units which are appropriately positioned with respect to the turbine assembly and each other such that the heated up vapours of working fluid are made to travel and strike the turbine with a pressure sufficient enough to rotate the turbine and generate power. Once the vapours pass through the turbine, they are made to travel back to the heating unit via cooling unit where they are cooled down to a liquid form which can be reutilized for another cycle. The power plant of the present invention is functional even with the ambient heat of the atmosphere and does not require any fuel consumption during its working.

A system for providing electrical power includes a high temperature heat source, an ambient temperature heat sink, an ORC generator, a solar thermal collector, and an SDES device. The ORC generator includes a generator working fluid with a boiling temperature greater than an ambient temperature of the ambient temperature heat sink, and the generator working fluid receives heat from the high temperature heat source and exhausts heat to the ambient temperature heat sink. The solar thermal collector is in thermal communication with the high temperature heat source to heat the high temperature heat source. The solar thermal collector includes a photovoltaic (PV) module, and the solar thermal collector is configured to convert a first portion of sunlight to thermal energy and a second portion of the sunlight to electrical energy. The SDES device receives electrical energy from one of the ORC generator and the PV module.
