The Congress of South African Trade Unions, the nation’s biggest labour federation, will present its proposal to rescue state power company Eskom. to senior members of government and the business community on Monday.

The union group, an ally of the ruling African National Congress, wants the government-owned pension fund, the Public Investment Corp, and state lenders, the Industrial Development Corp. and the Development Bank of Southern Africa, to take over R254 billion ($17 billion) of the company’s debt, Matthew Parks, Cosatu’s parliamentary co-coordinator, said in an interview Friday.

“We are ready for a fight,” Parks said, adding that the federation is aware there will be opposition to the plan.

The alternative is that Eskom will collapse, causing economic pain and job losses, he said. The meeting on Monday will be with the so-called President’s Working Council, which includes government, business and labour leaders.

The plan would leave the embattled power company that provides 95% of the country’s electricity with R200 billion of debt, an amount it has previously said it could manage.

Eskom is failing to cover its running costs and inadequate maintenance is leading to frequent plant breakdowns and rolling power outages. Those are stalling economic growth.

Cosatu represents 800,000 government workers, about four times its closest rival, and the PIC mainly manages the pension funds of civil servants.

The PIC, which has more than R2 trillion under management, also manages unemployment and worker-compensation funds.

Under the agreement, the PIC would provide the bulk of the debt relief, due to its size, and the government could also make a contribution depending on its finances, Parks said.

The debt relief would include assuming about R104 billion of Eskom debt already held by the PIC, he said.
