Step 1: Generation
Electricity is generated from various sources.
Step 2: Step-up transformer
Voltage is increased to push the electricity over long distances.
Step 3: Transmission power lines
Lines carry electricity over long distances.
Step 4: Transmission substation
Voltage is lowered so electricity can travel across the local system.
Step 5: Distribution substation
Voltage is lowered further for safe distribution.
Step 6: Distribution power lines
Electricity travels across these lines in your community.
Step 7: Final stop
A transformer reduces voltage a final time, and electricity is sent to your home.
