The government would implement an electricity-rationing programme as a "quick-hit" solution to address the current power blackouts, said Sonjica.
"We have discussed how quotas will be allocated, who will be exempt from the programme, what incentives and penalties will be in place, when it will start and what legislative enablers we need to have in place for the programme to work," Sonjica said.
When this rationing programme would be implemented was not clear. Eskom CEO Jacob Maroga said it might take "weeks to months".
A concept proposal on the rationing programme submitted to the Cabinet includes quota allocations for various electricity users, penalties and cut-offs, quota trading and flexibility of the programme.
It is designed to achieve the overall savings target of between 10% and 15% over time.
To have an immediate saving of 8%, industrial users would have to use 10% less electricity; commercial users 15% less; hotels, resorts, shopping malls and conference centres 20%;, large office buildings, the government and municipalities 15% less; agriculture 5% less; and residences 10%.
Penalties, which are yet to be determined, would be given for electricity use above the allocated quota and electricity supply to repeat offenders would be cut off.
An incentive scheme is being established for smaller consumers who exceed the savings targets, while large consumers could trade the unused portion of their quota allocations.
