热效率、容量系数、环境考虑、投资、燃料和O&M成本是太阳能电站技术经济评估的主要参数。分析表明，具有67 MWe太阳能场的集成太阳能联合循环系统（ISCCS-67）是伊朗第一座太阳能发电厂的最佳方案。联合循环和ISCCS-67电厂的平准化能源成本（LEC）将相等，如果ISCCS-67资本成本的4900万美元由国际环境组织，如全球环境基金（GEF）和世界银行提供。研究表明，ISCCS-67在30年的运行期内节省燃油消耗5900万美元，减少CO2排放约240万吨。ISCCS-67电厂的另一个优点是涡轮机容量增加50%，总效率提高4%。在考虑环境成本的情况下，ISCCS-67的LEC分别比联合循环和燃气涡轮机低10%和33%。
Thermal efficiency, capacity factor, environmental considerations, investment, fuel and O&M costs are the main parameters for technical and economic assessment of solar power plants. This analysis has shown that the Integrated Solar Combined Cycle System with 67MWe solar field (ISCCS-67) is the most suitable plan for the first solar power plant in Iran. The Levelized Energy Costs (LEC) of combined cycle and ISCCS-67 power plants would be equal if 49 million $ of ISCCS-67 capital cost supplied by the international environmental organizations such as Global Environmental Facilities (GEF) and World Bank. This study shows that an ISCCS-67 saves 59 million $ in fuel consumption and reduces about 2.4 million ton in CO2emission during 30 years operating period. Increasing of steam turbine capacity by 50%, and 4% improvement in overall efficiency are other advantages of ISCCS-67 power plant. The LEC of ISCCS-67 is 10 and 33% lower than the combined cycle and gas turbine, respectively, at the same capacity factor with consideration of environmental costs.
