The document discusses integrated solar combined cycle (ISCC) technology, which combines concentrated solar power with a combined cycle power plant. It outlines key design considerations for ISCC including solar resource, land availability, topography, the age and capacity factor of the fossil plant. It also discusses transient operation modeling and provides an example of the Martin Solar Energy Center ISCC plant. Charts show the modeled and actual power output over time for the plant. References on ISCC simulation and integrating solar and conventional energy resources are also provided.
