Load Modelling for a Federal Medical Center in Nigeria under Erratic Power Supply

Load data of a Federal Medical Center (FMC) in Nigeria, under prevailing erratic power supply from Nigeria’s electric power distribution company (DisCo) feeders, were considered to develop model load curve and electricity use values for planning effective electricity use and management. The analytical methods applied include nominal load evaluation for the entire FMC, data acquisition by direct hourly load monitoring for 12 months, diesel fuel consumption observation for power supply during DisCo outages, energy metering, outage events and durations, descriptive statistical evaluations of data. The results obtained and analysed include the following: nominal load, daily load and electricity use models. The results established daily load curve and parameters, such as load factor, daily average power and expected electrical energy consumption model in a typical Nigerian FMC. Model load factor is 0.545, which would be uneconomical especially when using standby generators the whole day due to failure of Disco feeder.
