JOHANNESBURG, June 14 (Reuters) – South Africa’s cash-strapped state utility Eskom said some of its power stations were operating below full capacity on Wednesday, after union members blocked some staff from entering around 10 plants because of a wage dispute.
Two labour unions, angered by Eskom’s failure to raise salaries as it embarks on a cost-cutting drive, have warned that thousands of their members will march to Eskom’s headquarters on Thursday to keep up the pressure in the wage talks.
President Cyril Ramaphosa has made stabilising state-owned firms such as Eskom a priority.
Eskom, which produces more than 90 percent of South Africa’s power, has so far refused to cede to demands by the National Union of Mineworkers (NUM) and National Union of Metalworkers of South Africa (NUMSA) to raise salaries by 15 percent.
A third union, Solidarity, is also unhappy with Eskom’s decision to keep salaries flat but did not protest on Wednesday.
“We have activated our contingency plans. All power stations are operating, some of them not at full strength,” Eskom CEO Phakamani Hadebe told a news conference.
He added that a dispute-resolution body would try to broker a wage deal between Eskom and the disgruntled unions.
Thava Govender, an Eskom executive responsible for generation, said shift workers had been intimidated as they arrived for work on Wednesday and that around 10 power plants were operating with reduced operating and maintenance staff.
Govender said Eskom was not able to quantify how severely power supplies had been affected but that it would become clear when demand peaked later in the day.
Eskom spokesman Khulu Phasiwe said police were at several power stations to protect staff and Eskom equipment.
Power supplies could also be affected on Thursday as NUM energy coordinator Paris Mashego said unions could bring more than 20,000 out of a total of 47,000 Eskom employees to a picket at the utility’s headquarters in Johannesburg.
Eskom narrowly avoided a liquidity crunch early this year. Ramaphosa oversaw the appointment of Eskom’s Hadebe on an interim basis in January in a bid to clean up governance and set the firm on a firmer financial footing. Hadebe’s appointment was
made permanent last month.
