While both are part of the electrical grid, they serve different functions:

• Transmission moves large amounts of electricity at very high voltages (typically 69 kV to 765 kV) over long distances, from power plants to substations. It's the bulk transport of power.

• Distribution takes the high-voltage electricity from substations and steps it down to a lower, safer voltage (typically under 33 kV) for local delivery to homes, businesses, and industrial facilities. It's the final-mile delivery network.
