PROYECTO DE EJECUCIÓN DE UNA PLANTA SOLAR FOTOVOLTAICA UTILITY SCALE EN SAN JUAN DEL PUERTO (HUELVA)
Abstract
El proyecto presenta las etapas necesarias para la ejecución de una planta solar fotovoltaica de 48 MW de potencia nominal y 58,5 MWp, ubicada en la localidad de San Juan del Puerto (Huelva). Las fases del estudio son las siguientes: selección del emplazamiento, diseño y elección de equipos, estimación de la producción energética, diseño de la instalación eléctrica y de la obra civil, y evaluación de la viabilidad económica.
En primer lugar, se selecciona un terreno que cumple con criterios de irradiación, accesibilidad, orografía favorable y cercanía a infraestructuras eléctricas.
La conexión a la red se realiza mediante la subestación ONUBA de 220 kV.
El diseño de la planta se realiza con PVSyst. Se emplean 105.408 módulos Jinkosolar de 555 Wp montados sobre seguidores en estructura 2V, junto con 14 inversores Sungrow de 3437 kW. La planta alcanza una producción media estimada de 116,157 GWh anuales, lo que se traduce en 1985,8 horas equivalentes y un factor de capacidad del 22,7%.
La instalación eléctrica genera energía en corriente continua a 600 V, que se eleva sucesivamente hasta 30 kV antes de su evacuación a la red. La planta presenta cables de aluminio con aislamiento XLPE. Además, se describe la correspondiente subestación elevadora. En cuanto a la obra civil, se describen caminos internos y de acceso, sistemas de drenaje, zanjas para cableado y un vallado perimetral.
El estudio económico incluye un presupuesto de 40.469.686,05 €. Con un LCOE de 23,35 €/MWh y un precio de venta de 42,30 €/MWh, se obtiene un valores del VAN del proyecto de 19.001.009,09 € y del 8,99% para la TIR, lo que confirma la viabilidad técnica y económica del proyecto.
The project outlines the necessary stages for the implementation of a 48 MW nominal power and 58.5 MWp photovoltaic solar plant located in San Juan del Puerto (Huelva). The phases of the study include: site selection, system design and equipment selection, energy production estimation, electrical and civil works design, and economic feasibility assessment. First, a site is selected based on criteria such as solar irradiation, accessibility, favorable topography, and proximity to electrical infrastructure. The grid connection is made through the 220 kV ONUBA substation. The plant design is carried out using PVSyst. It includes 105,408 Jinkosolar modules of 555 Wp mounted on 2V structure trackers, along with 14 Sungrow inverters of 3437 kW each. The estimated average annual production is 116.157 GWh, equivalent to 1,985.8 full-load hours and a capacity factor of 22.7%. The electrical installation generates direct current at 600 V, which is successively stepped up to 30 kV before being injected into the grid. The plant uses aluminum cables with XLPE insulation. The design also includes a step-up substation. Regarding the civil works, the study describes internal and access roads, drainage systems, cable trenches, and perimeter fencing. The economic analysis includes a total budget of €40,469,686.05. With a Levelized Cost of Energy (LCOE) of €23.35/MWh and a selling price of €42.30/MWh, the project yields a Net Present Value (NPV) of €19,001,009.09 and an Internal Rate of Return (IRR) of 8.99%, confirming the project's technical and economic viability.
