Rotating machines

AEMI has a growing activity in hydroelectric power renovation projects.  The company is involved in two ways:

  • as a main contractor

AEMI has participated in returning infrastructure of the Zongo, Koni and Mbuji Mayi power plants into service as the main contractor, in particular generators of a power of less than 15 MW.

  • as a subcontractor

On the Inga II, N’Seke and N’Zilo power plants – large-scale projects – AEMI is the subcontractor for international companies responsible for large-scale renovation. Thus, for Inga II, AEMI has stacked generators with a power of 170 MW for Alstom-General Electric.

2 workshops in the DRC

As regards electrical repair, the AEMI workshops, in Kinshasa and in Likasi, are the only ones in the DRC to have all the equipment required to meet international standards. AEMI carries out repairs and renovations in its workshops, but the staff can also assist on site at the customer’s request.

Since 2017, AEMI has been officially certified to distribute, repair and maintain Siemens products in the DRC.
