A trade union and civil society coalition has vowed to protest against Eskom's proposed 16% electricity increase outside a public hearing in Cape Town this week.
Metalworkers' union Numsa spokesperson Castro Ngobese said that they would picket outside the Cape Town International Convention Centre on Tuesday morning.
The CTICC is the venue for the first hearing by the National Energy Regulator of South Africa.
The union feared jobs would be lost and the cost of living increase should Eskom's application to Nersa succeed.
Christelle Terreblanche, speaking on behalf of the One Million Climate Jobs Campaign and other organisations, said that they have been given permission to demonstrate outside the convention centre at 1pm on Tuesday.
