Malawi: Escom, Egenco Move in to Improve Electricity System Stability

Electricity Supply Corporation of Malawi (ESCOM) Limited and Electricity Generation Company (EGENCO) Malawi Limited will on Wednesday launch Automatic Generation Control (AGC) to improve system stability by introducing generation fast response to power demand changes in real time.

ESCOM Chief Operations Officer (COO), Maxwell Mulimakwenda said all was set for the launch of AGC in Blantyre to ensure balance between generation and load demand, frequency as well as power interchange with other systems.

“AGC is a modern way of operating and controlling generators to improve frequency regulation and system stability,” Mulimakwenda said.

Minister of Energy, Ibrahim Matola is expected to grace the launch, which will be spiced up by a parade from Victoria Avenue to Sunbird Mount Soche Hotel.

Currently, ESCOM manages generation control through its National Control Centre with EGENCO performing a similar task through its Generation Control Centre whereas local power plant operators do so via their generation sites using telephones.

However, Mulimakwenda said changes effected in the power sector, especially with the integration of renewable energy, has rendered the current system challenging — hence AGC’s introduction.

“AGC will achieve stable frequency regulation by sending automatic signals to four generators via the SCADA system.

And guess what, this historic event has been achieved through collaborative efforts by ESCOM, EGENCO and Southern Africa Energy Programme (SAEP).”
