Maputo — Mozambique's publicly owned electricity company, EDM, has warned that Maputo and the neighbouring city of Matola will suffer intermittent power cuts at peak times for about two weeks due to the replacement of equipment at the Infulene sub-station.
Restrictions in electricity supply are because EDM intends to replace the existing Infulene transformer of only 60 MVA (mega volt ampere) with a much more powerful transformer of 250 MVA, imported from Portugal.
EDM has warned consumers that the work at Infulene will begin on 26 April, and is likely to last a fortnight.
The director of the southern transmission department of EDM, Gil Massinga, cited in Friday's issue of the independent daily “O Pais”, said that the purpose of replacing the transformer is to improve the quality of electricity in the areas supplied via the Infulene substation. The new transformer should end the power oscillations and cuts which consumes have long complained about.
But in the short term cuts will continue. “We are forecasting power cuts, but short ones, since we are making efforts that this will not be critical”, said Massinga. “We intend to make our clients aware of this situation”.
In addition to Maputo and Matola, the areas that could be affected include the southern provinces of Gaza and Inhambane.
Refurbishing the sub-station had become necessary because the existing equipment was obsolete. “The equipment we have in this substation dates from 1971”, said Massinga. “It's between 40 and 42 years old, and it no longer supports peak demand in the southern region”.
EDM had already done all the work that it was possible to do without interrupting electricity supplies, he said. But now the rehabilitation was at its most critical phase, “and the moment has come when we have to interrupt supply in order to put the new transformer into operation”.
