The electric connectivity & delivery system is the bridge between electricity generation and consumption. Thus, it must accommodate the needs of both end users and generators.

All forms of electricity generation must be sited in areas that meet specific criteria: thermal power plants require a reliable supply of fuel and meet local air emissions standards; hydroelectric dams must be sited in strategic locations along existing waterways; wind turbines require sufficient wind speeds; and solar panels need sufficient sunlight. Thus, the electric grid must extend from the locations of individual generators to collect power for delivery to consumers. In some cases, generators and consumers are in the same location.

The electric delivery system has two major components, transmission and distribution, with a third to possibly become more important in the future, storage. The transmission system uses high-voltage power lines to interconnect electricity generators with major urban areas and other load centers. The distribution system collects power from the transmission system and distributes it to individual consumers using lower-voltage power lines. Unlike transmission and distribution that connect generation and consumption between different locations, storage systems connect between different points in time.
