Objective
- Demonstrate the viability of solar energy integration in a conventional power plant, as a basis for the commercial exploitation of a hybrid solar energy-fossil fuel plant and evaluate this benefits.
- Analyse the operation of a Solar Central receiver System that will enable developing this technology for future applications under more demanding conditions.
- Reduce pollutants emissions in electric energy production.
- Obtain a hybrid plant design that could be applicable to thermal power plants.
- Commercially develop this type of plants for future applications with increased efficiency and significantly reduced costs.
Design phase has obtained the next results (main chosen equipment are new) :
- The plant is based on the construction of a small combined cycle (70.4 MW) so that admit saturated steam of solar origin.
- The solar energy collector (21 MWt) and conversion system is formed by a Heliostat Field, a Central Solar Receiver, and its corresponding Tower.
- Water from the power plant's heat recovery boiler is sent to the Central Receiver. Saturated steam is generated in the Receiver, and injected in the heat recovery boiler.
- The gas turbine has a power of 42.7 MW and the steam turbine of 28.4 MW with sun and 20 MW without sun. The power plant net efficiency is 54% without sun and 61.3% with sun.
- The Heliostat Field is North-oriented and composed of 489 heliostats of 70 m² reflective surface each.
The plant proposed is based on the construction of a small combined cycle (70.4 MW) so that admit saturated steam of solar origin. The Project is located in the Power Plant of Cristobal Colon, on Huelva, Spain.
The solar energy collector (21 MW) and conversion system is formed by a Heliostat Field, a Central Solar Receiver, and its corresponding Tower.

The gas turbine has a power of 42.7 MW and the steam turbine of 28.4 MW with sun and 20 MW without sun. The power plant net efficiency is 54% without sun and 61.3% with sun.
This allows using a proven, relatively undemanding technology in the Central Receiver, which reduces costs and increases the reliability of the plant.
The Heliostat field is North-oriented and composed of 489 heliostats of 70 m² reflective surface each.
Contrary to traditional tendencies, in this plant the energy contribution of the solar receiver is not sought at the highest possible temperature compatible with the optical quality and the technological limitations of the material, rather this solar contribution is intentionally made at to relatively low temperature (the evaporation zone of the Rankine cycle) to relax the technological conditions of operation of the solar system, thus increasing its reliability and reducing its cost. That is, this proposed design chooses to forfeit an appreciable fraction of the solar radiation energy to obtain to reliable, cheaper system which saves primary fossil-fuel energy.
