Eskom was slammed at public hearings on its tariff hike application on Tuesday despite its argument that the proposed increase is as fair and low as possible.
Public hearings were held at the Cape Town International Convention Centre under the auspices of the National Energy Regulator of South Africa (Nersa).
The power utility wants to increase its tariffs’ by 16 percent a year over the next five years.
Speaker after speaker poked holes in Eskom's submission.
Liz McDaid of the Southern African Faith Communities' Environment Institute criticised the power utility for prioritising its revenue over service delivery.
Democratic Alliance Member of Parliament Lance Greyling said more transparency is needed around Eskom's cost of generation.
He told officials there are a number of figures floating around out there, leading to confusion.
Earlier in the day, Eskom boss Brian Dames told Nersa he believes the company has struck an optimal balance.
Congress of South African Trade Unions' Mike Louw wouldn't hear any of it. He said the poor would suffer the most.
