The economy shrank in the third quarter as logistics constraints and a chronic electricity shortage took their toll.
Troubled state-owned electricity monopoly Eskom was on Wednesday forced to ramp up daytime load shedding.
The plan sets out how billions of dollars in climate finance will be tracked and details potential investments.
Eskom announced last month that it would hand over responsibility for implementing load shedding to City Power.
Eskom will impose stage-4 power cuts from 2pm on Monday until 5am on Saturday as its generation woes continue.
Eskom reduced power cuts as severe outages earlier in the weekend allowed the “replenishment” of emergency reserves.
Stage-6 blackouts will be implemented with immediate effect and will continue until at least Monday.
Stage-4 load shedding has returned until further notice, Eskom said in the small hours of Wednesday morning.
South Africa is likely to prioritise energy security to avoid further damage to the economy, said CEO of the Energy Council.
Eskom will use a portion of $12.5-billion in multilateral loans to deliver power to areas where the grid is overloaded.
