Johannesburg - The first unit of South African power utility Eskom's Medupi power plant is still due to come on line in the second half of 2014, chief executive Brian Dames said on Tuesday.

Eskom, which declared power emergencies twice last week, is racing to keep the lights on in Africa's largest economy and Medupi's construction has been plagued by several delays in the past related to design flaws, labour unrest and other problems. - Reuters
