Johannesburg - Unplanned outages jumped to 5‚026 Megawatts (MW) on November 1 from 4‚374MW on October 29‚ Eskom said in its 85th system status bulletin.
Planned maintenance eased to 3‚956MW on November 1 from 4‚252MW on October 29 and 4‚014MW on October 25.
Eskom said it continued to make progress with its programme of planned maintenance “but the system remains tight”.
Available capacity was only 33‚088MW compared with peak demand of 31‚648MW on November 1 resulting in a margin of 4.4%‚ while on October 8‚ when peak demand was 31‚943MW‚ the margin was only 3.4%. The international norm is to have a margin of 15%.
Eskom’s internal benchmark is to have no more than 3‚600MW in unplanned maintenance‚ a benchmark it has so far missed more than 60% of the time so far this year.
