JOHANNESBURG - Eskom has warned the national power grid will remain under pressure for the rest of summer.

This means rolling blackouts are possible should the power utility experience technical problems.

Last year, the parastatal had to implement load shedding after a silo at Majuba power station collapsed, leaving the system extremely vulnerable.

Today, its largest power station is operating at almost 50 percent.

Eskom's Andrew Etzinger says the utility is still trying to fix the problem.

"The Majuba power station is producing roughly half of its normal output. The permanent solution will be once it's rebuilt. There's still a temporary solution in place, so that is certainly a big factor in putting pressure on the reserve margin at the moment."
