This paper presents an initial analysis of the technical viability, of the application for the commercial and pre-commercial wave energy technologies, to the Spanish coasts. This analysis provides an optimal framework for future research, choosing one technology and considering a concrete point of the Spanish coast, with their respective constraints such as, the regulatory aspect of the fees to be applied to such technology, and the restrictions related to the protection of the ecosystems, and other local activities not compatible with the technology.This work is continuing the initiative started by the Project Enola. Enola is a software that provides comprehensive and complete information, about the potential electric production, based on wave energy of the Spanish coast. After evaluating all the wave energy technologies available at this point, those more mature and viable have been selected; the parameters under which they are productive have been analysed; and the ideal areas for implementation on the Spanish coast have been determined, according to the potentials provided by Enola and the technical limitations of the technologies themselves. The results is a summary document where one can easily identify the best locations for the deployment of wave power plants (optimum output).
