Las plantas analizadas son de tecnología cilindro parabólica, Fresnel y torre central. Para ello se escogieron tres localidades pertenecientes a la región occidental, central y oriental; además, se analizaron dos tipos de enfriamiento: por aire y evaporativo. Las variables de análisis que se tomaron fueron: acuerdo de compra de la energía, tasa interna de retorno (TIR), valor actual neto (VAN), factor de capacidad, factor de conversión y cantidad de agua utilizada. Los resultados muestran que el costo del kWh oscila entre los 20 y 38 centavos según el tipo de tecnología y región de análisis.]]></p></abstract>

The technologies of the analyzed thermosolar plants are parabolic cylinder, Fresnel and central tower. The analysis variables that were chosen were power purchase agreement (PPA), internal rate of return, net present value, capacity factor, conversion factor and quantity of water used. For this, were selected three localities belonging to the western, central and eastern region. In addition, were analyzed two types of cooling: by air and evaporative. The results show that the cost of kWh ranges between 20 and 38 cents depending on the type of technology and region of analysis.]]></p></abstract>
