The Anti-Privatisation Forum (APF) will stage a protest on Tuesday when a hearing into Eskom's 34 percent tariff hike application enters its last day in Pretoria.

"The Anti-Privatisation Forum will be there today [Tuesday]... [to express] dissatisfaction with the proposed tariffs hikes by Eskom," APF spokesperson Sithembiso Nhlapo said in a statement.

"The tariff increases do not adequately protect poor consumers and will bring new hardships to communities already struggling for mere survival."

The National Energy Regulator of SA's (Nersa) is set to continue public hearings into the tariff increase application after several organisations opposed it on Monday.

Eskom's application for a 34 percent hike has raised the ire of civil society and labour movements, many of whom were presenting their arguments during the two-day hearings in Pretoria.

Nersa has received 170 submissions on Eskom's application, of which 25 would be heard during the course of the hearings.
