Estudio técnico-económico de tecnologías de energía renovable para la Granja Avícola Avitrave.

Abstract

The purpose of this study was to evaluate the pre-feasibility of different technological routes of renewable energy as alternatives to reduce the consumption of electricity from the public network marketed by the National Electricity Corporation, the use of diesel and eradicate the consumption of LPG used for heating in Avitrave Poultry Farm. Results obtained from the energy analysis during the productive period April-May indicated that the item for the acquisition of LPG represents the largest amount within the energy expenditure, with a percentage equal to 78.87%; followed by electricity consumption with 19.43%; and less diesel with 1.71%. These figures are related to a peak daily energy demand estimated at 197.35 kWhe and 535.98 kWht, and an annual demand of 113.48 MWhe and 167.10 MWht. The determination of the level cost as a parameter for evaluation and comparison between technologies was carried out using the models detailed in section 2.6 and the System Advisor Model (SAM) tool. Among the technologies for electricity generation, it was determined as the most profitable a PV system connected to the grid with polycrystalline technology of 270 Wp, with a level cost of 13.41 cents USD/ kWhe. While for heat production the minimum generation cost was 12.08 ctvs.USD/kWht, which corresponds to the technology with a hot gas and air exchanger based on rice husk, an alternative compared to turbo-heater technology. to LPG, it is convenient to implement from a LPG cost 2.5% higher than the current value.
