In recent years, the supply of energy by renewable systems has taken a lot of strength, particularly in this research is considered a strength in the application to telecommunications networks, specifically in the headend where the reception and processing of voice signals is carried out, video and data. In the headend it is transcendental that the supply of electrical energy exists, given that it is the most important area to be able to transmit and distribute the signals to the end customers. A field of interest is the use of renewable energy sources such as wind and solar energy, which even having access to the conventional distribution network, can be supported to guarantee continuity in the service to this sensitive area. In this document we examine existing works and present the fundamental principles and motivations necessary to a deep understanding of the use of renewable energy in the headend. In addition, we present a reference model for the renewable energy station. It provides a comprehensive overview and helps identify opportunities in this promising field of research related to telecommunications and renewable energy.
