**Abstract**

Technology parks are considered innovative environments for the development of new technologies, in a dynamic that can be explained by the micro level of multilevel analysis of the theory of sociotechnical transition, by contributing to explain the actors responsible for the process of development and dissemination of technology. The cases analyzed were composed of companies and eco-innovative projects in the renewable energy area of the Itaipu Technological Park. The methodology was based on a study of multiple cases of qualitative nature, supported by content analysis and triangulation of information. The main results showed that the ITP, with the support of its maintainer Itaipu Binacional, created an environment conducive to the development of eco-innovative companies in renewable energies, stimulating the exchange of knowledge between companies and favoring partnerships with national and international companies for technological development.
