[en] This report aim is to assess the repowering of a wind farm. First of all, it is explained in a general context the current situation of wind energy in Spain and in particular the repowering process. Focusing on case involving this project, an analysis of the location and facilities of the current wind farm is presented. The farm has 49 wind turbines type G58/850. It is essential to carry out an analysis of the wind resource of the area in order to evaluate the advisability of repowering the farm. Actually, the data acquired from the IDAE records that wind speed values are quite appropiate. Nowadays, the energy production of the park is around 158.875 MWh according to assumptions made before and can supply around 150.000 people. The purpose is to increase these result. Therefore, it will be studied the option of choosing higher power wind turbines from three different manufacturers. After an exhaustive study of the principal characteristics of these turbines, it is concluded that G132/5000 wind turbines are the most suitable ones. This work results assume that reconstruction of the park will be based on 14 turbines of that type. According to some estimation the park will provide an annual energy generation of 295.485 MWh. The repowering will also entail the redistribution of the new turbines as well as the civil works and the improvement of some road infrastructures. Finally, an important part of any project is the assessment of the viability. On the one hand, promoters must ensure that they fulfill all legal guarantees. On the other hand, some economic and environmental studies will be determined. According to them and the results obtained, park´s repowering can be possible.

[eu] Informe honek haize-parke baten berrindartzearen ikerketa aurkezten du. Lehenik eta behin, Espainiar estatuko energia eolikoaren egoera azaltzen da eta bereziki berrindartzearena. Aukeratutako parkean arreta jarriz, bere kokapeneko eta instalazioen analisia azaltzen da. Parkeak 850 kW-ko 49 haize-sorgailu ditu. Ezinbestekoa da parkea berrindartzearen ahaleran, leku horren baliabide eolikoen analisi zehatza egitea. Ikerketa honek IDAE organizazioak aurkitutako datuetan oinarritzen da eta horren arabera, haize abiaduraren balio egokiak erregistratzen direla aipa daiteke. Gaur egun, parkearen ekoizpen energetikoa 158.875 MWh-koa da eta 150.000 pertsona hornitu dezake. Proiektu honen asmoa aipatutako emaitzak handitzea da eta horretarako potentzia handiagoko haize -sorgailuak aztertuko dira, hiru fabrikatzaile desberdinen artean. Haien ezaugarrien ikerketa sakon baten ondoren, G132/5000 haize-sorgailuak hautatu egin dira, egokienak baitira. Lan honen ondorioz, berreraikitzeak mota horretako 14 turbina izango dituela azaltzen da eta horrek 295.485MWh urteroko energia ekoiztuko luke. Horrez gain, parkearen berrindartzeak turbina berrien antolakuntza zehazteak dakar, baita lan zibila eta azpiegitura batzuen hobekuntza. Azkenik, edozein proiekturen aurkezpeneko funtsezko oinarria beraren bideragarritasunaren ebaluazioa da. Batetik, sustatzaileek lege guztiak betezen dituztela bermatu behar dute . Bestalde, ingurumenari eta ekonomiari buruzko ikerketak aurkeztu beharko dira. Ikasketa hoien arabera, parkearen berrindartzeak aurrera eraman daitekeela adierazten da.
