The research, seeks to expose the current situation of the substation of 115kv thermoelectric plant, currently the capacitor banks are developed to the full range, allowing the correction of the power factor, making a diagnosis of the situation of low power factor in the substation and the selection of the type of bank which will be used according to the electrical characteristics of the company was made. The components of a capacitor bank to increase the power factor were identified. Likewise, the types of the main electrical parameters are described. Being referred in great part to the analysis of the efficiency of the capacitor bank for the increase of the active power in electrical substations which, in turn, will serve as a pilot to be applied in other capacitor banks with similar characteristics. Making use of the systemic method to identify the causes of the increase of active power in the substations, which will lead to make decisions in the respective strategic plan.

The purpose of the research is directed to the design of a Biodigester where bovine manure and wastewater are used for the creation of low-cost fuels. A Biodigester is a system that takes advantage of anaerobic digestion (in the absence of oxygen) making use of the bacteria that live in the manure, which help to transform it into biogas that will be used in kitchens and as an alternative source of electricity once it has passed through the electric generator of transformation that operates based on gas and in turn obtain the fertilizer called Biól, which after having served its time in the Biodigester is considered with the same importance as the Biogas since it provides an excellent natural fertilizer that improves the yield of crops, allowing to obtain a better product. Low-cost biodigesters have been developed and are widely implemented in Southeast Asian countries, but in South America, only countries such as Cuba, Colombia and Brazil have developed this technology. They are characterized by their low cost, easy installation and maintenance, using simple materials for their construction.
