The thesis was developed in the Power Plant of the city of Requena, to analyze the evolution of the environmental parameters in its power plant from the environmental monitoring of 2018 -2021. The research is non-experimental, analytical, predictive, horizontal and retrospective. Data variations from 15 quarterly environmental monitoring (04 years) were systematized and analyzed, and based on this analysis of trends and prediction of changes in environmental parameters through mathematical modeling using the Holt-Winters Model with exponential smoothing. The results show that the noise in the Requena power plant has a decreasing trend and the noise levels comply with the environmental quality of the noise, which are not higher than 80 dB. The prediction analysis for the next year reports a descending noise evolution from a maximum level of 61.02 dB to a minimum level of 58.12 dB. In the ...
