Abstract
Este proyecto trata de analizar la viabilidad económica de dos tipos de sistemas de tecnologías minieólicas (vertical y horizontal) aplicadas sobre una vivienda unifamiliar situada en Madrid en régimen de balance neto, de próxima aprobación.
En primer lugar se expondrá cuál es el estado actual del autoconsumo en España y en el mundo así como el balance neto. Por otro lado se analizará también y se desarrollarán ambas tecnologías minieólicas, describiendo sus principales características y componentes.
Se explicará también cuál es su funcionamiento y que alternativas existen para su instalación.
Se predimensionarán los dos tipos de tecnologías minieólicas utilizadas para aplicarlas sobre el caso de estudio, tomando como base el consumo energético de la vivienda objetos de estudio.
Conocidos los costes de la instalación que satisfacen dichas necesidades energéticas, se valorará la viabilidad económica de los miniproyectos, analizando las variables económicas más relevantes, tales como el VAN, TIR y retorno de la inversión, considerando varias hipótesis de instalación y varias hipótesis sobre el mercado eléctrico.
Finalmente se expondrán una serie de conclusiones derivadas del estudio económico realizado y se analizará si resulta o no rentable.
The Project is intended to analyse the future approval of the Royal Decree about energy production in terms of net metering in Spain. The net metering technology is based on the compensation of energy balances instantly or differes, unleashing a whole new bunch of possibilities for the consumer to produce his own energy for his particular use. This system is particularly interesting for power generation facilities, especially those renewables, as wind energy, solar-photovoltaic and microgeneration, because for the first time it lets them adjust their production to consumption without physical accumulation. With this system, any facility may produce energy for direct consumption under demand. If the demand of energy is higher than production it will be necessary to import energy from the electric network; but when the electricity demand is lower than production the energy will be exported to the electric network. The possibility that the net metering Royal Decree may succeed in the upcoming months makes it interesting to present the advantages and disadvantages of its application in a building and the economic benefits for the users under this modality. In this Final Degree Project, we will analyze self consumption through net metering systems and its regulations, as well as the installation of the renewable technologies of wind power with vertical and horizontal axis designs studying its application to residential building and concluding whether it would be profitable or not to carry it out.
