How electricity gets to you

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.
