Johannesburg - South African power utility Eskom warned of possible electricity outages on Wednesday and Thursday evening, saying its system was severely constrained.

Eskom has instituted at least three blackouts this year as demand, which peaks at about 36,000 megawatts during evening hours, put pressure on supply.

“Eskom will utilise all necessary emergency resources at its disposal to keep the lights on, but should the demand not decrease, load reduction will be implemented as a measure of last resort to protect the national grid from a total shutdown,” it said in a statement. - Reuters
