- distribution – the process of delivering energy (120 V to 34.5 kV) from substation to the end user
- components of the transmission grid
- power station
- step-up transformers
- switchyard
- transmission towers
- transmission lines (overhead and underground)
- transmission substations
- regulators
- components of the distribution grid
