This research is on the analysis and modelling of power consumption in a base transceiver station. For the purpose of this research, two base transceiver stations in Benin (BEN) were visited and data were collected and analysed: Ugbor station referred to as BEN035 (site A) and Benson Idahosa University referred to as BEN198 (site B). Analysis was made on AC power consumption and its Matlab plot. The model of Base station instantaneous DC power consumption for high and low traffic global system of mobile communication (GSM) usage was carried out by Matlab software to show how power is been consumed in a Base transceiver Station (BTS) and for future forecast.

Keywords : Base transceiver station, modelling, power consumption, Forecast, Matlab software and telecommunication.
