Spain's third largest utility, Unión Fenosa, claims that the first environmental ISO certificate for Spanish wind farms has gone to it renewables and cogeneration division, Union Fenosa Energías Especiales (UFEESA). The news will add value to UFEESA, part of which was put up for sale in December by its parent company Unión Fenosa (Windpower Monthly, January 2003). From the start of the year, all consumers may now choose their electricity supplier and utilities are expected to begin using every trick to polish up their green image. The certificate is for two wind stations, Careón and Castelo, both in Galicia. "The certification is the result of an environmental management system applied to these wind farms," says Unión Fenosa. This system is an adaptation of similar models implemented elsewhere by the utility making it -- in 2001 -- the first Spanish utility to receive environmental certification for its entire conventional generating capacity. UFEESA says it is the developer of 476 MW of wind in Spain. Meanwhile, Italian utility ENEL, already active in Spain's power market, has confirmed an interest in buying into UFEESA.
