EDM spokesman Luís Amado told the media in Maputo late on Thursday that “the water problem persists in the southern zone, and we are already on a red alert.”
He added that the Corumana dam produces 25 megawatts, but is currently producing half of that.
“The water problem continues, especially in the south. We are not able to produce in Corrumana. We have 25 MGW, but we are producing half because of the water shortage”.
In the center and north of the country, he said production is normal, but in case of low rainfall it can equally face the same problem as in the south of the country.
The shortage of water in southern Mozambique started at least two years ago. In 2016, in Southern Africa, one of the worst droughts was due to El Nino.
Southern Africa is still battling to recover from the 2015-16 El Niño-induced drought, which by last year had affected about 41 million people across the Southern Africa Development Community (SADC).
The Southern African Power Pool (SAPP), a common electricity market between 12 southern African countries has been under strain since late 2014 because of power supply constraints in its largest member, South Africa.
Low rainfall has also exacerbated the situation, reducing output from hydroelectric facilities.
