The research was carried out at the Iquitos Power Plant, in order to analyze the evolution of noise, air and water indicators and their parameters, based on environmental monitoring from 2018 -2021. The design is non-experimental, analytical, predictive, horizontal and retrospective. The secondary information was obtained from the quarterly reports of the Environmental Monitoring carried out by Electroriente. The evolution of the data from 15 quarterly environmental monitoring in their trends and prediction values was analyzed, for this the Holt-Winters Model with exponential smoothing was used. Which allowed to conclude that in the evaluation of the evolution in the indicators and their parameters: noise, air: PM-10 particulate matter, sulfur dioxide, nitrogen dioxide, hydrogen sulfide and in the effluent water: hydrogen potential (pH) , temperature (°C), electrical conductivity, disso...
