Due to increased demand of electricity in the country coupled with limited generation capacity in the hydro power stations, EGENCO runs Diesel power plants in order to suffices demand during peak periods.
Peak period are the times when there is high demand for electricity in the country. Usually it is between 5:30am – 8:30am, 11:30am-1:30pm, and 5:30pm-9pm.The diesel generators therefore run during these hours to supplement the hydro power stations.
Currently EGENCO has a Diesel Power plants in Mzuzu, Lilongwe and soon to open in Blantyre.
The total generation capacity is as detailed below:
