Power demand down - Eskom
Eskom is still calling on its consumers to switch off unnecessary appliances to save power.
JOHANNESBURG - Eskom says demand for electricity so far in 2012 has been two percent less than 2011.
The power utility says this is because of weaker economic growth, changes in commodities markets and efforts to save power.
Eskom released details of how tight the electricity supply is.
It says its systems are still very tight as the summer maintenance season approaches.
Eskom CEO Brian Dames says people are responding to power alert requests to switch off appliances they are not using.
"We have residential costumers responding [to requests to switch off] but there is opportunity [to do more]."
Dame says its coal stocks were also affected by the truck drivers' strike.
But he says the utility still has comfortable levels of supply.
"We are going into summer and we are going to do a lot of maintenance. We need everyone to save electricity."
