How electricity is supplied to our customers

At SA Power Networks we are just one link in the energy supply chain. There are many organisations and people working together to make sure you have power at home or to run your business.

These organisations:

• generate electricity (coal, gas, wind and large-scale solar);
• operate the transmission network, which carries electricity long distances at very high voltages;
• deliver it locally via substations, poles and wires (our role as distributor); and
• your retailer sources electricity from generators and manages your bill.
